Richer is Cleaner and Greener



Dispatches from a rapidly changing, rapidly improving world

The good news keeps rolling in. I hope to do a few more of these before real life resumes. Enjoy!

Use Energy, Get Rich and Save the Planet

By the 1990s, researchers realized that graphs of environmental impact didn’t produce a simple upward-sloping line as countries got richer. The line more often rose, flattened out and then reversed so that it sloped downward, forming the shape of a dome or an inverted U — what’s called a Kuznets curve. (See nytimes.com/tierneylab for an example.)

In dozens of studies, researchers identified Kuznets curves for a variety of environmental problems. There are exceptions to the trend, especially in countries with inept governments and poor systems of property rights, but in general, richer is eventually greener. As incomes go up, people often focus first on cleaning up their drinking water, and then later on air pollutants like sulfur dioxide.

As their wealth grows, people consume more energy, but they move to more efficient and cleaner sources — from wood to coal and oil, and then to natural gas and nuclear power, progressively emitting less carbon per unit of energy. This global decarbonization trend has been proceeding at a remarkably steady rate since 1850, according to Jesse Ausubel of Rockefeller University and Paul Waggoner of the Connecticut Agricultural Experiment Station.

The Good News

These Kuznets graphs confirm that the best way forward for the environment is by way of technological and economic development. Technological progress gives us the means of producing energy in increasingly clean ways and adds to our ability to mitigate damage that's already been done. Malthusian and Luddite approaches are wrong because they assume a zero-sum world (which this is not) and they ask the developing world to forego many of the benefits of technology and economic growth that we in the developed world take for granted, meanwhile demanding that the developed world to take this whole standard of living thing down a notch. Yet somehow a philosophy which is as indifferent to the human misery it allows (and causes) as it is ineffective in protecting the environment -- the developing world will just revert to burning charcoal and peat once you take all the other infrastructure away -- dubs itself Sustainability.

True sustainability requires adopting an approach that improves the lives of the people involved. There is only one truly sustainable direction for humanity...forward.

Coming Soon: The Ultimate Hybrid


Dispatches from a rapidly changing, rapidly improving world

Special Dispatch

I don't know how much time I'll have for blogging while I'm on paternity leave from work, but it'all going to be good news stories. Let's get this party started.

Lightning Hybrids Develops Biodiesel-Hydraulic Hybrid

The LH4 was designed by a company called Lightning hybrids and as stated above, is powered by a Biodiesel engine. Only 3 cylinders are needed to get the vehicle moving and power the hydraulic pump that takes the place of a traditional electric motor. Combined, the system is good for 100mpg, which will do very well in the race for the Automotive X Prize.

The Biodiesel-Hydraulic combination is also a wonderful choice in terms of performance. When the need arises, the LH4 can launch to 60mph in just under 6 seconds, which is nothing to sneeze at given the high fuel economy number it is able to return. The looks of the LH4 aren't bad either.


The Good News

When I first read about hybrid automobiles 20 years or so ago, two models were on the table: electric and hydraulic. With the advent of the Prius a few years back, and the rush of other car companies to follow suit, the term "hybrid" has become almost synonymous with "electric hybrid." There were a few announcements early on that some automakers were looking at the hydraulic approach, but announcements have been few and far between and production vehicles available to the consumer or commercial markets have been non-existent.

Please correct me if I'm wrong on this; if anyone is selling hydraulic hybrids I'd like to hear about it. Plus I'd be very interested to know how they're doing...

I always liked the elegance of the hydraulic model for hybrid automobiles: capture the forward momentum you normally lose every time you brake in the form of hydraulic compression. Then turn around and unleash that pressure next time you want to acelerate. This approach may provide a better fuel savings than electric hybrids can -- it certainly will for larger vehicles whose greater mass will pump massive amounts of force into the hydraulics system. You've got to love that 0 to 60 in six seconds. That's some pretty nice acceleration for a car that gets 100 MPG. Plus, the expectation is that hydraulics systems are more economical than the battery systems used in electric hybrids -- giving the hybrid shopper less sticker shock.

Perhaps most imortantly, having two working models for how to deploy a hybrid vehicle means competition. Hydraulic hybrids will drive improvements to electric hybrid systems and vice-versa. And one day, these two models might meet to provide the ultimate hybrid. Get that fossil-fuel-burning engine out of the loop and provide your primary power with an electric engine. Then use hydraulic brakes to capture your lost forward momentum. Now that would be an efficient model.

Sharing the Highway

When I was in California last week, I was driving down highway 101 south from SFO towards the San Mateo bridge when I passed (and was later passed by) a truck pulling a trailer with the Tesla logo proudly displayed. The trailer was fully enclosed, so I couldn't see the vehicle inside, but it was pretty cool to be sharing the road with the all-electric roadster of the future -- even if the Tesla itself wasn't moving under its own power.

Likewise, it will be very gratifying to see one of these babies out on the road in the very near future.

apterafromtherear.jpg

Interesting write-up available here. A year and a half ago, the Aptera seemed like a great idea, but a long way off and kind of science-fictiony. Now, not so much. Aptera appears to be on its way.

T. Boone Pickens Town Hall in Shreveport, LA

T. Boone Pickens came to my home town Shreveport yesterday as part of his campaign for the Pickens Plan. It was set to start at 10:30, and I showed up a few minutes early to make sure I could get a decent seat.

Out in front of the Shreveport Civic Center were two CNG vehicles. One was a GM Impala and the other was a Chesapeake work truck. Unfortunately neither is in production right now. If you want to be a CNG early adopter you essentially have one choice in the United States today - the Honda Civic GS CNG.

I got inside and got a great seat on the second row. When the rally started 30 minutes later, the room was completely full (picture gallery here [Hey, that's me in photo 8]).

A video showing T. Boone's travels on this campaign rolled to the tune of Johnny Cash's "I've Been Everywhere." T. Boone is shown hopping from city to city on various talk shows and rallies throughout the country.

Then our local Senator David Vitter came out and introduced T. Boone.

Pickens was given a standing ovation as he approached the podium from the back of the hall. Shreveport is a very friendly crowd for this guy. He's advocating a move from petroleum to natural gas to people living on top of the biggest gas field in the United States.

tboone.jpg

T. Boone looks like he's one of those rare 80-year-old guys with another 20 years left in him. He got to the stage and - with a quick hand up from Vitter - did this funny hop step 3 feet up onto the stage. He didn't bother with the stairs at the side of the stage.

He got straight to the point - we import 70% of our oil. Nixon thought we had a problem back when we imported 24% of our oil. At this summer's peak prices we were sending $700 Billion overseas annually for petroleum. We can't afford this now. And if we don't do something it will get worse. Pickens says that by 2018 we'll be paying $300 a barrel for oil. It will break this country.

Get this kid to MIT...

...fast!

12-year-old William Yuan has invented a new, improved 3D solar cell.

william yuan.JPG

William invented a novel solar panel that enables light absorption from visible to ultraviolet light. He designed carbon nanotubes to overcome the barriers of electron movement, doubling the light-electricity conversion efficiency. William also developed a model for solar towers and a computer program to simulate and optimize the tower parameters. His optimized design provides 500 times more light absorption than commercially-available solar cells and nine times more than the cutting-edge, three dimensional solar cell.

You know, this kid might just have kicked us over the Solar Singularity finish line. Grid parity has already been achieved in Hawaii - where there is plenty of sun and electricity is otherwise produced via diesel. But this development could bring solar to the rest of us.

More on 3D solar cells here.

Running Like Clockwork

Back during the 1970's my Grandfather Shelby Gordon spent much of his retirement in his wood working shop. He made wooden swings, shelves, and - most impressively - grandfather clocks. Here's the one I have in my dining room:

GG clock.JPG

You don't plug these clocks into the wall. They use weights. About once a week you pull the chains to raise the weights up and they slowly work their way down.

I thought about that clock when I read this article about storing wind mill energy:

...one of the most serious issues raised by the [wind power] naysayers was that the wind does not always blow when you need it.

But a New Jersey company plans to announce on Tuesday that it is working on a solution to this perennial problem with wind power: using wind turbines to produce compressed air that can be stored underground or in tanks and released later to power generators during peak hours.

Its a great idea in part because its so simple. It doesn't require expensive batteries or capacitors to store power. Just an air compressor. Its a totally mechanical solution.

With similar ease weights like in my grandfather clock could store power. These windmills are very tall. For perspective, check out the stairs/service entrance at the bottom right of this windmill:

windmill2.JPG

If the wind is blowing hard when the price of electricity is low (like at night), why not have the windmill pull weights up to the top of the tower? It could be engineered to pull several weights or geared to slowly pull one very large weight up the tower. When the electricity is needed the weights would fall.

One of my economics professors once told me that the purest application of supply and demand theory he ever saw was at a hydroelectric dam control center. The controller watches an indicator that tells what the supply is - water behind the dam - and another indicator shows the price of electricity. These indicators were probably analog dials back when my professor toured that plant. I'm sure its computerized now. But they try to match power generation to that time when the price of electricity (and the need for electricity) is highest. Unless, of course, the water gets too high behind the dam. Then they'll generate regardless of the price of electricity.

Whether the answer is compressed air or weights, mechanical storage would allow windmills to function like hydroelectric dams and be better at providing power when its needed. And that would also improve the profitability of these power plants.

MIT, Aussie Boffins Produce Cheaper Hydrogen

In last night's Fast Forward Radio discussion of future vehicular fuel sources I tossed out a couple of bits of recent research that might make Hydrogen a bit more of an option in the intermediate future.

It seems that considerable advances have been made in the last few months in terms of generating Hydrogen from sources other than fossil fuels.

My claim of "near 100% efficiency" comes from this EETimes piece (via Instapundit and ChicagoBoyz) describing MIT research using a liquid Cobalt Phosphate catalyst to do the job.

"[W]ith our catalyst almost 100 percent of the current used for electrolysis goes into making oxygen and hydrogen."
-- Daniel Nocera, MIT Chemistry Professor.

Meanwhile, in Australia, Monash University scientists have succeeded in producing Hydrogen (and Oxygen) gas directly from sunlight and water, using a slightly charged (1.2V) Nafion (wikipedia) substrate doped with Manganese "clusters". See this recent Gizmag piece (Artificial Photosynthesis provides clean, cheap Hydrogen) for additional details.

A Short Bridge to EV's

Hybrid electric/gasoline vehicles have been thought of as a bridge technology to full electric vehicles. There are a number of factors that could make the bridge long (25+ years) or short (a decade). Paypal cofounder and Tesla chairman Elon Musk is betting on a short bridge. Here's why:

  1. Hybrids represent a poor compromise. The product is neither a good EV or a good gas powered vehicle.
    EM: Because you need both a gasoline-powered engine and a big battery, neither can be very good, and the engine will be a weak engine. It's just not where the future lies.

  2. Batteries capable of offering EV's comparable range to gasoline vehicles will be available sooner than most people think.

    EM: We'll be able to offer a car with a 305-mile range roughly three years from now.

    ...

    I think what we'll see is an increasing amount of energy being stored in the battery pack and a lowering of the cost of the battery pack over time.

    ...

    If you look at the improvement of battery energy density, it tracks to about 8 or 9 percent a year.

  3. Tesla will address the EV road trip problem with their second model.

    EM: There is the occasional road trip, but that's actually pretty rare, and for some people it's never. Our second model will address that rare case in two ways. One is to allow people to switch out the battery pack, so you can go to a battery-change station just like you'd go to a gas station. The second path is to have a high-speed charge. If you have a high-powered onboard charger, you can get an 80 percent charge in 45 minutes. If you're going from L.A. to San Francisco, which is about a 400-mile trip, you can drive 200 miles, stop for lunch, charge your car in the restaurant parking lot, finish lunch and continue the remaining 200 miles to San Francisco.

  4. And there will be improvements to EVs beyond batteries that will enable EV's.

    EM: [Battery improvements are] not the only thing. The efficiency of the electric motor, the efficiency of the powertrain, the rolling resistance are all important.

  5. Part of the electric infrastructure improvement necessary for EV's can be done right at the EV owner's residence.

    EM: I have another company, SolarCity, which is the largest provider of solar power to homes and businesses in California. The solution is to get a SolarCity solar panel on your roof and then have an electric car. It takes actually only a small solar-panel setup - of about 10 by 15 feet - to generate 200 to 400 miles a week of electricity for your car.

Read the whole interview.

(H/T to Michael Darling)

Musk didn't mention it, but there's another factor that would tend to push us to EV's quickly:

  1. Skyrocketing gas prices.

    Dude. We're there.

    No, I'm talking about $7,8... $10/gallon gas. If gas prices go in that direction the hybrid's gas engine will look less like a feature than a bug.

Economic Inevitability

I'm all for fresh oil drilling, for getting shale up and running, for converting coal to methanol and trash to ethanol that we can burn in our flex fuel vehicles. I like the idea of diesel sourced from algae and bacteria that excretes crude oil. I'd be proud to drive around fueled by used french-fry grease, and I think converting atmospheric CO2 into gasoline is a swell idea.

Those are all great ideas and I think we should pursue each and every one of them enthusiastically. But I'm starting to think that the real future of automotive transportation has little if anything to do with liquid fuel (or even natural gas.) Here's why.

I drive one of these and I love it.

Impreza.jpg

With my Impreza, I get between 22-32 MPG. With gas anywhere from $3.90 - $4.35 a gallon, let's just round everything off and say that I'm paying about $4 for every 25 miles I drive. That doesn't sound like such a bad deal until you consider what it ought to cost to drive something that looks like this:

zerotruckdisguised.jpg

Take one of these Ero trucks, load it up with freight, drive it 50 miles to its destintation and then 50 miles back home, how much would you expect to shell out? Keep in mind that such a trip will run you about $16 in my moderately fuel efficient Subaru. At least twice as much, right? Call it $30 at the barest minimum

Would you believe 10% of that? How does $3 sound for a 100-mile trip?

The's because our "Ero truck" is really a Zero truck, an Isuzu modified to run on expensive-to-buy-but-oh-so-inexpensive-to-operate lithium batteries. Go back and read over all those fuel options I listed at the beginning of this post. Do any of them promise to deliver 100 miles of driving for three dollars?

I didn't think so.

zerotruck.jpg

Electric cars are the way this thing is going to work out, folks. Yes, there are major issues to be resolved around developing more efficient batteries, extending the range these things can drive, figuring out a way to charge up quickly, etc. And of course, the biggest issue -- how do we source all that electricity?

Mr. Pickens' continent-sized wind farm is one idea. Getting serious about nuclear is another.

But it's simple economics in the end. That 13 extra bucks I'm paying for every 100 miles of driving could be better spent on -- so many things. Multiply that by the 20,000 miles I'm likely to put on my car in a year, and that's $2600. Multiply that by the five years I'm taking to pay off my car and we're looking at a break even point of an all-electric Subaru Impreza -- with a sufficient range to get me from Highlands Ranch to Boulder and back, slightly more than the 100 miles that the Zero truck delivers -- costing about $13,000 more than what I paid for mine.

Faster, please.

The Pickens Plan

Solar as a Service

Drive around and look at the rooftops in your neighborhood. If your town is anything like where I live chances are you won't see any solar panels. Take a good look. In fact, take some pictures to document how your town looked circa 2008. By 2018 those rooftops will, mostly, have solar panels. Don't worry they won't be ugly boxes- at least not for long. The way solar will look will change too.

Solar has been around for decades, but it hasn't been accepted. Things are about to change - partly due to technology, but also because we'll find the right business model.

A good example of how this worked is the mobile phone. They were also around for decades before they were broadly accepted. In the 1967 movie Clambake, Elvis Presley's character took a call on a car phone. It was a plot point that his oilman dad had to call every mobile phone register throughout the country to find him. And of course it was very important to the believability of this car phone that Elvis' character was very rich.

clambake phone.jpg

In the 1987 movie Wall Street, Michael Douglas' character did business from the beach with this brick:

wallstreet phone.jpg

We laugh at the brick now - you could throw a hip out carrying this in a holster - but it was an incredible leap forward from the Elvis phone. It was no longer tied to a car. And it was a true cellular phone - no mobile registers to call - just dial the number like a house phone. On the downside it was still analog. And it was still a status symbol - Gordon Gekko had one because he was rich.

By the time of the 2004 action film Cellular, it was an important plot point that everyone had cellphones.

15102__cellular_l.jpg

Cellphones are dirt cheap now. I got laughed at the other day when I pulled out my Go Phone. Yeah, I bought this thing around Christmas of 2006 for $20 as a "disposable" cell phone. Its still going strong. I plan to become marginally less dorky by buying an iPhone... soon.

Anyway, solar will be adopted in a similar fashion. Sunshine's free, but the panels have been expensive. Payback on these things has been longer than their useful life. Typically people have resorted to solar only if grid electricity was unavailable. That's changing. The word is that solar is slowing becoming competitive with grid power.

There's been another problem with solar - you get the risks associated with owning the power plant. If there's a problem at the hydroelectric damn its not your problem, but if there's a problem with your solar panel, it is your problem.

Until now. Recurrent Energy is now offering "solar as a service." They come to your site, set up the panels, and plug you in. They maintain ownership of the panels, so if there's a problem, they'll fix it. They promise that their service "supplies competitively priced solar electricity, displacing expensive peak-time utility power."

I think this business model will be an important part of the move to solar. If the price is competitive with the grid (or better) and the risks of ownership remain with a power company, why not make the move?

Go-Grease Lightening

If there's anyone who doubts that higher gas prices will encourage people to adopt alternatives, consider this:

grease gone.jpg

Used cooking oil stolen — by biodiesel pirates

SAN FRANCISCO - A few years ago, drums of used french fry grease were only of interest to a small network of underground biofuel brewers, who would use the slimy oil to power their souped-up antique Mercedes.

Now, restaurants from Berkeley, Calif., to Sedgwick, Kan., are reporting thefts of old cooking oil worth thousands of dollars by rustlers who are refining it into barrels of biofuel in backyard stills.

Who says we aren't building more refineries? They've just been forced underground.

When gas was a $1.00 a gallon used cooking oil went to the dump. It just wasn't worth the work of collecting it and processing it into diesel (or, alternatively, altering a diesel engine to run on cooking oil). Legitimate grease collectors are understandably upset about thievery, but it's a sign that the stuff they're collecting has real value now.

A possible answer to this problem is to start paying the restaurants for the amount of grease they provide. Once the cost of theft is pushed to the restaurants, they'll keep the grease under lock-and-key until the collection truck comes by.

Used cooking oil is helping some individuals motor around, but it isn't a national answer. We don't eat that many french fries. We really do need to build some new commercial refineries and drill more domestically. But also, this story provides proof that as the price of crude rises the opportunity for a profitable alternative fuel industry opens up. Funding the expensive R&D for new battery technology suddenly looks sensible. As does exploring the possibility of algae biofuels.

Algae Economy, Part 2

For the last couple of days the Drudge Report has had a red link at the top of the page to this news story:

'Squawk Box' Guest Warns of $12-15-a-Gallon Gas

In a television interview (which you can watch at that article) energy expert Robert Hirsch stated that a $12 gallon of gas is “inevitable.” I think he's wrong.

It's true that oil production has remained flat, but Hirsch is only counting oil that we can pump out of the ground. Biofuels are not part of his thinking.

I think $5 and $6 per gallon gas may be inevitable. But as the pain increases, the money flowing toward alternatives will increase. And we have some very promising alternatives. Plug-in hybrids will be hitting the market in the next couple of years. At $5 per gallon for gas those hybrids will sell much faster than the automotive industry will be able to make them. The energy consumption patterns will change overnight in this country. Perhaps we should be a little more concerned about the electricity infrastructure. Nuclear energy has to be part of our thinking.

But we'll still need liquid fuel. And here's the most promising new source:

Important statistics from this story:

  • 100,000 gallons of biofuel per year per acre for algae crops. This compares to 20 to 30 gallons of biofuel per acre for corn crops.

  • If we used 1/10th of the state of New Mexico for this Vertigro system, it could supply all the transportation fuel this country needs.

  • The most ideal place to grow algae is in the desert. No farm land is sacrificed, no food crops are sacrificed.

In the last video I posted on this guy, he explained that different algae species could be used to make different fuels. You'd could develop a jet fuel algae, a diesel algae, and a gasoline algae.

UPDATE: For convenience, here's that first video:

Ethanol: the Other Side

I was pleased to see (via InstaPundit) this favorable treatment of Robert Zubrin's views on ethanol in Newsweek. I don't think corn-based ethanol is a great way to go, especially with the heavy subsidies that seem to be required to make it happen, but at least we can have a little clarity on whether ethanol production is causing a food shortage.

It isn't.

If we're going to produce ethanol, there are much better ways to go than corn. Sugar beets would make more sense, as would organic waste. Or we might think about importing ethanol if we're really serious about the stuff.


Probably a better fuel for humans than vehicles

The other day I heard a radio ad for a local auto dealer touting its leadership in providing flex fuel vehicles within the state of Colorado. That strikes me as progress. But I want to see pumps dispensing pure ethanol (from sources other than corn) and methanol. I would take both of those as significant signs of progress.

UPDATE: More on importing. This s about as political as I ever like to get. But even if, for whatever reason, you disagree about dropping the tariff on imported ethanol, at least here's something more interesting to look at tan that tired corn photo, above.


May 08, 2008


The (Solar) Singularity is Near

One of the reasons I don't lose sleep over Peak Oil is that there is such a broad range of alternative energy sources under development. The list includes, but is not limited to, the following:

Nuclear Fission
Solar
Concentrated Solar
Ethanol -- from switchgrass, cornstalks, etc.
Ethanol -- from waste
Methanol -- from coal
Synthfuel -- from coal
Synthfuel -- from shale
Synthfuel -- from tar sands
Biodiesel -- from waste
Biodiesel -- from algae
Nuclear Fusion

Progress is being made on all of these fronts. And if oil shoots up to $200, $300, $400 per barrel over the next couple of years, we can expect interest in these (as well as funding applied to them) to skyrocket.

Let's look at just the second and third items on the list, the two major forms of harnessing energy from the sun. What we normally think of as "solar energy" is the application of photovoltaic technology -- turning the sun's power directly into electricity. "Concentrated solar" power, AKA solar thermal energy, involves concentrating and capturing heat from the sun, which is then used to create steam and move an electricity-producing turbine.

We wrote about the tremendous promise of concentrated solar power just a few weeks ago, so I won't rehash all that here. Suffice it to say that, even if photovoltaic technology had hit some kind of peak of its own, meaning that we wouldn't expect much more from it than what we're getting now, concentrated solar would remain as a major potential energy source that we have barely even begun to exploit.

But the truth is that photovoltaic solar energy is far from any peak. Ray Kurzweil has repeatedly stated his assessment that solar energy is on a Moore's-Law-style trajectory of its own, and that all the worlds energy could be supplied by solar in as little as 20 years. So if Moore's Law is leading us to The Singularity, is this acceleration of solar power capability leading us to a solar singularity?

Some probably wouldn't like that term, seeing as it could make the whole question as to what exactly we mean by "singularity" even murkier than it currently is. But it has a ring to it, doesn't it?

Solar Singularity.

Anyhow, if we are going to get to the point where solar really does (or even could) supply all the world's power within a couple of decades, we are obviously going to have to see:

Accelerating progress in solar energy technology culminating in a fundamental shift in how the world's energy needs are met.

And that, then, can be how we define the solar singularity. It seems unlikely that it could be confused with any other kind of singularity, doesn't it?

We talked briefly on the most recent FastForward Radio about how we would know when we've reached the solar singularity. One suggestion was "when solar is cheaper than anything else." Another was "when they don't even bother to drill any more." Those are both good candidates. But how could we ever get to that point?

LED Bulbs Getting Ready for Prime Time?

They certainly produce more visually pleasant light than compact fluorescents. And you don't have that pesky toxic-cleanup issue if one breaks. But are LED-lightbulbs ready to take on the incandescent bulb?

Lighting Science Group says they are. And to back it up, they're introducing a new line of LED-based lightbulbs that plug into a regular light socket. Check out the bulb shown here.

LEDbulb.jpg

Looks pretty neat. And as we can see from this page, it can be had for a mere $110.

What the...$110???

For a LIGHT BULB?

Well, hang on. LSG has an answer to that:

At $40 to $110 apiece, the LED "in-screw" bulbs may still seem too pricey for a lot of consumers. But Lighting Science Group's pitch is that a 50 cent Edison bulb will last for 750 to 3,000 hours, while an LED has to be replaced only every 50,000 hours (or 10 to 30 years). The company says the cost savings is almost $740 over a lifetime due to much lower energy consumption.

That's the same argument that's made in favor of the compact fluorescents, but these bulbs last longer and are even easier on the old electric bill.

Plus, I think I already mentioned -- no mercury.

Bring 'em on, I say.

Concentrated Solar Power: Another Great New-Old Idea

Writing for Salon, Joseph Romm says that concentrated solar power (CSP) is the key to solving our energy problems.

One of oldest forms of energy used by humans -- sunlight concentrated by mirrors -- is poised to make an astonishing comeback. I believe it will be the most important form of carbon-free power in the 21st century. That's because it's the only form of clean electricity that can meet all the demanding requirements of this century.

Romm argues that CSP, which uses heat from the sub to move an electricity-generating turbine (as distinct from photovoltaics, which convert sunlight directly into electricity) can produce energy more efficiently coal or oil or even nuclear power. He claims that CSP can provide power at a cost of 10 cents per kilowatt hour or less. Concentrated solar power's big advantage over conventional solar power has to do with storage:

The key attribute of CSP is that it generates primary energy in the form of heat, which can be stored 20 to 100 times more cheaply than electricity -- and with far greater efficiency. Commercial projects have already demonstrated that CSP systems can store energy by heating oil or molten salt, which can retain the heat for hours. Ausra and other companies are working on storing the heat directly with water in the tubes, which would significantly lower cost and avoid the need for heat exchangers.

Romm provides a number of interesting examples of CSP applications throughout history. Before the invention of photovoltaics, CSP was the only real model for generating solar power. He even gives an example of a CSP-powered pumping station that was built and put into operation in Egypt in 1913. It was shut down during WWI, and then never reopened once cheap oil established itself as the dominant energy source.

So it's interesting to see CSP making such a striking comeback. It reminds me of the recent news about production of automobiles running on compressed air - another idea that was experimented with a century or so ago, then pretty much forgotten, and which has now found new life. New technologies and new market conditions provide the opportunity for abandoned and all-but-forgotten ideas to re-emerge. My favorite example of this has to be the idea of building a Charles Babbage-style difference engine at the nano scale -- a model of computing that would have been awkward and clunky to implement using 19th century industrial technology, and which was deserted in favor of 20th century electronics technology, now finds new life with 21st century nanotechnology.

Zero-Emission Aviation

Hydrogen has a long (if somewhat spotted) history of making things go up. For starters, hydrogen gas is lighter than air. In fact, it's even lighter than helium, which is why -- along with a US embargo preventing the German government from getting their hands on sufficient quantities of the inert gas that today we use to lift children's party balloons and to make our voices squeaky -- the ill-fated airship Hindenburg was put aloft by hydrogen gas. Sadly, hydrogen's extra boost of lift power came with a high level of volatility and flammability, and I think we all know the rest of that story...

But there are other ways that hydrogen can make things fly. For example, Boeing has recently announced that, earlier this year, the aircraft manufacturer demonstrated the first-ever manned flight of an airplane powered entirely by a hydrogen battery. NASA tells us that aircraft account for "up to 4 percent of the annual global CO2 emissions from fossil fuels near the Earth's surface as well as at higher altitudes (25,000 to 50,000 feet)," so there is definitely something to be said for airplanes with a carbon footprint of zero. The question is, how close does this initial 20-minute demo flight get us to a future of zero-emission aviation?

Not very, according to Boeing:

The director of the Ocana research centre, Francisco Escarti, said the hydrogen battery "could be the main source of energy for a small plane" but would likely not become the "primary soruce of energy for big passenger planes".

"The company will continue to explore their potential as well as that of all durable sources of energy that boost environmental performance," he said.

But Boeing is not the only game in town where hydrogen-powered flight is concerned. As we reported a couple of months ago, the European Space Agency is looking at an idea called LAPCAT (Long-Term Advanced Propulsion Concepts and Technologie) which promises not only to deliver large-scale, hydrogen-powered commercial aviation, but to return us to the era of supersonic commercial aviation. UK-based Reaction Engines, who have proposed LAPCAT and are currently working with the ESA to study its feasibility, claim that their jet will deliver cruising speeds up to Mach 5, making it possible to fly from Sydney to Brussels in about four hours.

Consider the possibilities: a jet that can fly faster than the Concorde -- with a much greater range than Concorde's, too -- which will have none of the Concorde's negative impact on the atmosphere. Moreover, Reaction Engines claims that the greater range means that LAPCAT will be able to fly routes that can minimize or avoid "supersonic overflight of populated areas." So we can once again travel faster than sound, this time with less worry about potential resulting noise pollution.

Of course, there's a hitch to hydrogen-powered aircraft. In fact, it's the same hitch that you get with hydrogen-powered anything. Hydrogen is a means of transporting energy; it is not itself an energy source -- at least not when burned like a conventional fuel. So if we want truly zero-emission aircraft, we need to make sure that whatever is serving up LAPCAT with hydrogen fuel, or charging the batteries of Boeing's more modest offering, is itself a green and emission-free energy source. Solar, wind, and hydroelectric would all be good ways to produce energy for zero-emission aviation. But if we were to look to look to a future in which all aviation becomes zero-emission, we will need something more scalable and reliable than any of those.

For the near- to mid-term, that probably means nuclear energy. For the longer term, fusion energy will eventually supply us with cheap and abundant power without the risks or drawbacks associated with nuclear fission reactors. (Although it's important to note that those risks and drawbacks have been considerably reduced in the more recent versions of nuclear fission reactors, which has significantly broadened the appeal of these low-emission power plants.) Mimicking the process by which the sun itself is powered, fusion is perhaps the ultimate natural energy source. And it's fueled by hydrogen -- meaning that a future of zero-emission aviation may be hydrogen-powered in more ways than one.

Less Gas is Always Greener

Without looking, what would you guess is the subject of the Wired article "'Misinformed Craze' For Hybrids Delays Greener Technology?"


Guess 1:

I was sure initially that the author was suggesting that standard hybrids are delaying plug-in hybrids.

Thanks to the nickel batteries in standard hybrids, there's a good argument that these "green" cars are worse for the environment than my Ford Explorer. This is tragic because, well, it exposes my witty title as a lie.

Plug-in hybrids will be doubly better for the environment. We will be able to drive emission-free for most commuting and the batteries necessary to power a plug-in hybrid are environmentally friendly too.

But it doesn't look like plug-ins are being held back by the standard hybrids. Most major car companies, plus a few upstarts, are getting into the plug-in business as fast as they can. In ten years we'll probably look back at standard hybrids as a brief, necessary bridge to plug-ins.

Prediction: the word "standard" won't describe non-pluggable hybrids for much longer.

But that's not what the Wired article is about.


Guess 2:

Perhaps the author is arguing that somehow hybrids as a whole - standards and plug-ins - are holding back the development of full EV's.

Now this would be an interesting article too. But hybrids aren't holding EV's back any more than standard hybrids are holding back plug-ins.

EV's are being held back by a chicken/egg problem. Few people will buy EV's until they are comparable to gas guzzlers in range, speed, and the ability to fuel up quickly at convenient stations. No EV's, no infrastructure. No infrastructure, no EV's.

Plug-ins will, I think, serve as a proving ground for the EV’s that follow. They could also provide the infrastructure for EV's. Plug-in owners will buy gas for long trips until enterprising station owners offer quick charge service that's cheaper than gas. Once that service is widespread, we'd have a network of stations that full EV's could use. Perhaps Congress should mandate standardized quick charge jacks in plug-ins to encourage this.

But no, that's not what the Wired article is about either.


The Big Reveal:

The article states that hybrids are holding back other technologies like...hydrogen. This according to two French researchers who also concede that hydrogen won't be commercially viable until 2025 at the earliest.

If we ever do get hydrogen fuel cell vehicles (a rather big if) they will also be electric vehicles. A hydrogen fuel cell would power a car with electricity. Wouldn't it be beneficial to have already perfected electric vehicles? Right now the best path to electric vehicles is through hybrids.

There's no need to wait to 2025 to do something. We will experiment with many possibilities between now and then.

Carbon Recycling

In a recent post Phil asked, "So are we better off strictly recycling, or with a mix of recycling for metals and plastic, while reclaiming energy from paper and other organic waste?"

There's an interesting parallel between recycling and "reclaiming energy." Recycling allows you to use the same raw materials over and over. Reclaiming energy allows us to use carbon over and over.

Fossil fuels release carbon that's been sequestered since the fossils they were made from were living. Ethanol releases carbon too, but it's the product of plants that sequester carbon while they grow (paper and organic waste sequestered carbon recently). Instead of a one-way release of carbon, we'd get to take advantage of a carbon cycle. This makes it closer to being carbon neutral.

But NPR reported today on a study that apparently shows that ethanol is worse for the climate than gasoline. Their reasoning: when we devote more of our corn crops to ethanol, world food production is shifted to places like Brazil where rain forests are slashed and burned for farm land. And burning of rain forest releases a lot of carbon.

This highlights the importance of using things other than food to make ethanol. Making cellulosic ethanol from biological waste (like corn stalks) or switch grass could be carbon neutral. Using land that's not being used for crops wouldn't be a problem. Algae for diesel and ethanol can be grown in the desert.

Unfortunately that's not the message that most people will take away from that study. "Ethanol is worse than gas." Well, no. Ethanol can be much better than gasoline for the environment. We just have to be careful about unintended consequences. Perhaps it's time to end corn ethanol subsidies.

Recycling and Alternatives

Per Bylund writes about the Swedish government's coercive recycling regulations:

...[E]verybody is recycling. But that is the result of government force, not a voluntary choice. The state's monopolist garbage-collection "service" no longer accepts garbage: they will only collect leftovers and other biodegradables. Any other kind of garbage that accidentally finds its way to your garbage bin can result in a nice little fine (it really isn't that little) and the whole neighborhood could face increased garbage collection rates (i.e., even larger increases than usual — they tend to increase annually or biannually anyway).

So what do you do with your waste? Most homes have a number of trash bins for different kinds of trash: batteries in one; biodegradables in one; wood in one; colored glass in one, other glass in another; aluminum in one, other metals in another; newspapers in one, hard paper in another, and paper that doesn't fit these two categories in a third; and plastic of all sorts in another collection of bins. The materials generally have to be cleaned before thrown away — milk cartons with milk in them cannot be recycled just as metal cans cannot have too much of the paper labels left.

The people of Sweden are thus forced to clean their trash before carefully separating different kinds of materials. This is the future, they say, and it is supposedly good for the environment.

What is interesting about this Soviet-style planned recycling is that it is officially profitable. It is supposed to be resource efficient, since recycling of the materials is less energy-consuming than, for instance, mining or the production of paper from wood. It is also economically profitable, since the government actually generates revenues from selling recycled materials and products made in the recycling process. The final recycling process costs less than is earned from selling the recycled products.

However, this is common government logic: it is "energy saving" simply because government does not count the time and energy used by nine million people cleaning and sorting their trash. Government authorities and researchers have reached the conclusion that the cost of (a) the water and electricity used for cleaning household trash, (b) transportation from trash collection centers, and (c) the final recycling process is actually less than would be necessary to produce these materials from scratch. Of course, they don't count the literally millions of times people drive to the recycling centers to empty their trash bins; neither do they count, for instance, energy and costs for the extra housing space required for a dozen extra trash bins in every home.

Not to get into the politics of whether the Swedish government should or should not enforce such a vigorous model of recycling, I wonder how reclaiming refuse for biofuel production might fit into such an environment? All the wood, paper, and organic waste which is currently going for recycling or trash disposal might be converted into energy instead. I'm not sure this would make things any easier, but I would venture to guess that (at least) folks wouldn't have to sort paper into different varieties or wash out their milk cartons before disposing of them.

There has been quite a bit of interest in cellulosic ethanol lately; I wonder how enthusiastically its widespread production from waste materials would be received by environmentalists? While you would no longer have paper ending up in landfills, you would have it being "used up" in the form of energy production. Whereas, with recycling, the paper will last a lot longer -- although certainly not forever.

So are we better off strictly recycling, or with a mix of recycling for metals and plastic, while reclaiming energy from paper and other organic waste?

Hydrogen on the Cheap

Yesterday, in response the the latest Better All the Time post I commented:

I do have one prediction about hydrogen. We will find much more efficient ways to get it than water electrolysis. For example, green plants get hydrogen from water as part of the process of photosynthesis. This is done very efficiently (and why would nature bother to get hydrogen from water if hydrogen were useless?). We are beginning to understand how this works and we might use that method to get hydrogen.

Or, we might use John Kazius' microwave method.

Or there might be some other way that that I won't know about until... today. According to Technology Review, scientist have known since the 70's that a material called titania serves as a catalyst for breaking down water into hydrogen and oxygen in the presence of light - specifically ultraviolet light.

The problem is that sunlight is only partly UV. The process would be much more efficient if titania split water with visible light too.

Nanotech to the rescue. Scientists with the startup company Nanoptek have just announced that putting titania on dome-like nanostructures stretches the bonds between the titania atoms so that it begins splitting water with visible light.

This process is said to be as cost effective as the current cheapest way of obtaining hydrogen - from natural gas. But since the natural gas process releases a significant amount of CO2 and this method releases only oxygen, this is the environmentally friendly approach.

One way this could really be useful is in storing solar power for night use. These dishes could produce hydrogen during daylight for powering fuel cells 24/7.

Now this is what I'm talking about...

fiskerkarmadetroitproduction.jpg

...well almost.

This is the Karma plug-in hybrid. It's fast, its beautiful, and it will go 50 miles before burning a drop of fuel. The one feature that I could do without is the $80,000 sticker price.

Maybe if I planned an eco-friendly mid-life crisis...

Nah. I'll wait for others to pay for the R&D that went into this car and then purchase the $30,000 Honda Accord plug-in that will follow in 3 or 4 years.

On the other hand, that Accord probably won't go 0-60 in 6 seconds. Sigh.

The Race to Plug-In

Saturn has announced that it will sell a plug-in version of the Saturn Vue in late 2009. Toyota will sell a plug-in Prius in 2010. The Chevy Volt will also have a plug-in version in 2010.

chevrolet-volt-picture-3-703660.jpg

Plug-ins will be compared to each other on how far they will be able to travel as electric vehicles per charge. The Saturn plug-in will run 10 miles on electric per charge. The Prius will only go 7 miles. The Volt (pictured above) will go 40 miles per charge.

That 30 mile advantage for the Volt over the other plug-ins will make a huge difference at the pump. Running as an EV is the equivalent of paying $.75 cents per gallon for gasoline. And being able to go 40 miles per charge means that many people won't have to burn gas at all during their daily commutes. I wouldn't. But I would burn some gas with the Saturn and Prius plug-ins.

Of course I'm burning gas with my current vehicle. Plug-ins, even ones with modest EV ranges, will be a huge step forward.

UPDATE: GM is calling the Volt their "Moon shot." And, just in case you're not convinced that this is a race...

There's nothing magic about the technology. Two or three years after the Volt is introduced, everybody will have something like it. We'd just like to be first for once.

The $2,500 Car

Take a look at part of the reason that petroleum will never be cheap again:

2500 car.jpeg

This is Tata Motors "Nano" car. It will seat four adults comfortably and will sell for about $2,500 US in India and other developing countries. A version of this cute car might even make it to the US. This is the 21st century's answer to the VW Bug.

A car this cheap will allow millions in India, China and elsewhere to purchase a car for the first time. As more people demand petroleum the price of that resource will continue to climb - even without the peak oil nightmare.

We as a country have to get serious about flex fuel vehicles, ethanol and biodiesel production, battery R&D, and nuclear power. The quicker we push the alternatives, the less the pain of transition.

Switchgrass Looks Promising

Not to get a whole thing going again, but one of the arguments offered against flex fuels is that any flex-fuel program requires ethanol and ethanol (if it could ever work at all) is problematic in that its production requires making energy production competitive with food production, which can drive up the price of produce such as corn which is applicable to both.

One solution, as I noted in the comments section of that lengthy discussion, might be to open up other agriculture markets for fuel production, while relegating corn back to what it's best at -- feeding us and our livestock. At the same time, we might look at crops that would give us a bigger bang for our buck in terms of domestic ethanol production. As reader Odograph pointed out, it would be next to impossible for the US to match Brazil's successful ethanol program, partly because corn just doesn't crank out energy as efficiently as sugarcane, and partly because we're such pigs when it comes to energy consumption.

Solutions such as plug-in hybrids might at least cut down our rate of consumption of liquid fuels for powering cars (if not our total energy footprint). I mentioned crops such as sugar beets, fodder beets, and sweet sorghum which yield ethanol at about the same rate as sugar cane. And here's another possibility, which we discussed briefly on our most recent podcast -- switchgrass:

Previous studies on switchgrass plots suggested that ethanol made from the plant would yield anywhere from 343% to 700% of the energy put into growing the crop and processing it into biofuel. But these studies were based on lab-scale plots of about 5 square meters. So 6 years ago, Kenneth Vogel, a geneticist with the U.S. Department of Agriculture in Lincoln, Nebraska, and colleagues set out to enlist farmers for a much larger evaluation. Farmers planted switchgrass on 10 farms, each of which was between 3 and 9 hectares. They then tracked the inputs they used--diesel for farm equipment and transporting the harvested grasses, for example--as well as the amount of grass they raised over a 5-year period. After crunching the numbers, Vogel and his colleagues found that ethanol produced from switchgrass yields 540% of the energy used to grow, harvest, and process it into ethanol. Equally important, the researchers found that the switchgrass is carbon neutral, as it absorbs essentially the same amount of greenhouse gases while it's growing as it emits when burned as fuel.

switchgrass.jpg

Switchgrass looks promising, but it's no panacea. As a natural part of the North American prairie ecosystem, this plant has been touted by some as a crop that could solve all our energy needs with minimal fertilizer, herbicides, or other inputs. But the research says not so fast:

A final significant finding, Vogel says, is that yields on farms using fertilizer and other inputs, such as herbicides and diesel fuel for farm machinery, were as much as six times higher than yields on farms that used little or no fertilizer, herbicides, or other inputs to grow a mixture of native prairie grasses. That result contrasts sharply with a controversial study published just over a year ago in Science that suggested that a mixture of prairie grasses farmed with little fertilizer or other inputs would produce a higher net energy yield than ethanol produced from corn (Science, 8 December 2006, p. 1598). Instead, the current study--published online today in Proceedings of the National Academy of Sciences--shows that switchgrass farmed using conventional agricultural practices on less-than-prime cropland yields only slightly less ethanol per hectare on average than corn. "The bottom line is that low-input systems are not economically viable," Vogel says.

Switchgrass may be part of the overall solution, but it's going to take some real effort to make it work.

Zubrin on the Glenn and Helen Show

Robert Zubrin is featured on the most recent Glenn and Helen Show, talking about his book, Energy Victory -- which is apprently doing quite well. (He was also a guest on FastForward Radio not long ago.) Now Glenn reports that a member of John McCain's campaign staff has contacted him to point out how Senator McCain is all about Flex Fuels.

Here's hoping that some (or all) of the other candidates chime in. Before Christmas, I started a list of people who I think need to read Zubrin's book. Let's add all the candidates' names to that list. A sane energy policy could be closer then we think!

The Ultimate Hybrid

Some great alternative energy ideas are emerging around our two most recent posts on the subject. Stephen has us powering our homes with either miniature nuclear reactors or nano-solar panels. Reader Da55id, in the comments section of the earlier post, suggests using those some solar panels to launch a potentially workable version of the hydrogen economy:

1.) Water is delivered via current water pipes (no charge)

2.) Solar power cracks the water to yield hydrogen (appx $15k investment)

3.) The hydrogen is stored to be used by fuel cell that the govt funded to ensure that critical infrastructure can be "battery powered" for months at a time AND this same tech can backup whole houses...and now for the final piece.

4.) The electricity generated by the hydrogen runs your Tesla of Chevy Volt (saves you about $3,000 in gasoline costs per year)

I like this. It seems a reasonably workable model for hydrogen, using it to store solar energy, which has this little not-always-available issue associated with it.

Meanwhile, Will Brown is offering up a veritable smorgasboard of new battery technologies and new approaches for solar, nuclear, and hydrogen power.

Everybody wants their electric car now, it seems -- and I'm right there with you, guys -- but if I were a betting man, I would predict that we'll still be using internal combustion engines for at least a couple more decades. Rarely does Phil Bowermaster want to err on the side of caution when it comes to the roll-out of new technologies, but what with this whole thing going on, and all...

President Bush on Wednesday signed an energy bill designed to cut U.S. dependence on overseas oil by imposing the biggest increase in fuel-efficiency standards in 32 years and mandating a fivefold increase in the use of home-grown biofuels.

"Today we make a major step toward reducing our dependence on oil, confronting global climate change, expanding the production of renewable fuels and giving future generations of our country a nation that is stronger, cleaner and more secure," Bush said in a ceremony at the Department of Energy.

...I think we have to be (and again, nobody hates this word more than Yours Truly) realistic. The new law requires that cars become 40% more fuel-efficient (in 12 years) and that we make some modest progress in ethanol and other biofuels. Clearly, the US Government is not on a Speculist time schedule.

Baby steps, guys. Baby steps.

We'll have electric cars in a few years, but we're going to muck around with hybrids for a while until we get it right. And, yes, I think we'll have mini-nukes or hydrogen fuel cells or nano-solar collectors powering nano-wire batteries to generate electricity for our homes and cars, but this is all going to take a while. In the mean time (building on a all of these various ideas), I would like to see us work towards a scenario where every new vehicle built is either:

1. A flex-fuel plug-in hybrid, or

2. A diesel plug-in hybrid

Today we have a lot of cars running on gas, a few plug-in hybrids running on gas and grid power, and a few vehicles out there running on biodiesel. Petroleum is still dominant. But if every new car fit into one of those two categories, we would eventually see our vehicles powered by:

Fuels
Petroleum
Methanol
Ethanol
Diesel
Biodiesel

The Grid
Fuel Oil
Coal
Hydroelectric
Nuclear
Wind

Off the Grid
Nano-Solar
Hydrogen Fuel Cells
Compact Nuclear

Most of these different approaches to fueling cars actually work together -- so you can have a flex-fuel car burning any combination of gas and alcohol while getting its battery power from the home system, which is half nano-solar and half coal power from the grid. Or you could have your biodiesel car with its battery charged from a compact nuclear power source or a hydrogen fuel cell charged by nano-solar. Choices!

Sooner or later, the less environmentally friendly options (standard gas and diesel, and coal) have to start being phased out in favor of the lower-emission options. But in a world where just about anything you can think of can power your car, that shouldn't be that hard to do.

UPDATE: Then again, maybe the future isn't that far away. Glenn directs us to a video of a test drive of the 300MPG Aptera, which we recently blogged about.

Cheaper Than the Grid

Electricity is the ultimate commodity. Whether it comes from a coal burning plant, wind mills, or from a hydroelectric plant; an electron is an electron. When powering your toaster, one is as good as the next.

This commodity problem - from the point of view of those who are producing power - is compounded by the fact that customers can't choose where their power comes from. If you'd rather your power came from a clean source - well, tough. You don't get that choice. If you're on the grid your electricity could come from basically any source anywhere in the country - clean or dirty.

Power sources compete on one basis - price. And, unfortunately, environmental impact is a cost that usually falls outside of price. There are a couple of ways out of this trap. We could tax dirty power. But, right or wrong, we've usually lacked the political will to put the cost of environmental impact back on the energy consumer.

The less painful way out is to find ways that clean power can compete with dirty power on the basis of price. Putting filters on smoke stacks can't do that. Any effort to clean up a dirty process makes that power more expensive than the dirty original - just like taxing. We need entirely different clean power sources.

Hydroelectric power is cheap and clean, but we've basically maxed out on that in this country. Wind power can compete with grid power on the basis of price and this resource has not been fully exploited; but there is a limit to the amount of power that the wind can provide.

There are two more cheap and clean sources of electricity that I read about just today. First, the Nanosolar Company has begun selling new advanced solar panels that are actually cheaper than grid power.

The company, which has raised $150 million and built a 200,000-square-foot factory here, is developing a new manufacturing process that “prints” photovoltaic material on aluminum backing, a process the company says will reduce the manufacturing cost of the basic photovoltaic module by more than 80 percent.

Nanosolar, which recently hired a top manufacturing executive from I.B.M., said that it had orders for its first 18 months of manufacturing capacity. The photovoltaic panels will be made in Silicon Valley and in a second plant in Germany.

...

Nanosolar’s founder and chief executive, Martin Roscheisen, claims to be the first solar panel manufacturer to be able to profitably sell solar panels for less than $1 a watt. That is the price at which solar energy becomes less expensive than coal.

“With a $1-per-watt panel,” he said, “it is possible to build $2-per-watt systems.”

According to the Energy Department, building a new coal plant costs about $2.1 a watt, plus the cost of fuel and emissions, he said.

Another possibility is the mini-nuclear plant. Phil mentioned these in a recent Better All The Time entry. But Glenn Reynold's link today points to an article with this fact about mini-nuclear plants:

The whole process is self sustaining and can last for up to 40 years, producing electricity for only 5 cents per kilowatt hour, about half the cost of grid energy.

We may live to see dirty power plants mothballed for the most practical of reasons - the price.

All I Want for Christmas is a Sane Energy Policy

To use a cliche from a few decades back, I think my "consciousness has been raised" by reading Robert Zubrin's new book, Energy Victory. It seems that everywhere I turn, I encounter someone who says something that reminds me of the book, and that makes me want to give them a copy. So I'm starting a last-minute Christmas list of people I want to share the book with.

For example, yesterday I followed a link over at Jerry Pournelle's site to the text of a speech by Newt Gingrich entitled Sleepwalking into a Nightmare. In the speech, Gingrich lays out one of the major propositions of Zubrin's book -- a sound and sane energy policy, one that gets us off Saudi oil once and for all. But he blows it almost immediately, to wit:

And let's be honest: What's the primary source of money for al Qaeda? It's you, re-circulated through Saudi Arabia. Because we have no national energy strategy, when clearly if you really cared about liberating the United States from the Middle East and if you really cared about the survival of Israel, one of your highest goals would be to move to a hydrogen economy and to eliminate petroleum as a primary source of energy.

Emphasis added. One thing Zubrin makes very clear is that the "hydrogen economy" is simply not a workable idea. Hydrogen burns clean and would be a terrific alternative to gasoline if it were available on its own. Unfortunately, on this planet it comes packed with oxygen in the form of water. In order to free up hydrogen atoms to burn as fuel, we have to expend energy to release them from their bond with the oxygen atoms. In fact, the amount of energy we have to expend is, at best, only equal to the amount of energy we'll get burning the hydrogen. There's no net gain.

So somehow we have to generate the energy required to free up all that hydrogen. And that needs to be a clean and non-foreign source of energy. So naturally the question becomes --once we've figured out what that is, why not just use it instead of hydrogen? Cut out the middle man, as it were.

The hydrogen economy is, if anything -- according to Zubrin -- a diversion backed by the oil companies. It allows President Bush and other politicians to take the position that they are in favor of getting us off oil while backing a proposal that is very unlikely to do so. Meanwhile, we just keep chugging the oil.

So for Christmas, I want to give Newt Gingrich a copy of Energy Victory. In fact, I'd send him two copies if I thought he could get his friend President Bush to read one of them.

But I don't just want to give the book to my friends on the right. Oh, no. Others need to read it, too.

Last night I'm sort of half-watching Boston Legal. I don't really follow that show much any more (believing that it jumped the shark somewhere around the halfway point of the first season), but the lawyer who lives here at Casa Speculist is still a pretty big fan, so it was on. Anyhow, John Larroquette is making this closing argument about how hard it is to know what to do about saving the environment. As a throwaway, he mentions that ethanol is an attractive approach, except for the fact that filling the tank of a Hummer one time requires using the same amount of grain that would feed a human being for a year.

I'm not sure that I'm quoting that correctly, and -- even if I am -- considering the source, let's just say that there is some chance that it might be a bit exaggerated. Be that as it may, the problem with that argument is not the merits of the case, it's the assumption that energy is a zero-sum agricultural game. Zubrin points out that much of the developing world is starving not because we're burning all our grain in the form of ethanol, but because we refuse to import their agricultural products. If we want to help raise the developing world out of poverty, a huge step forward is to create a worldwide market for their agricultural produce -- for example, the ethanol market that Zubrin argues can free us from dependence on foreign oil.

So let me offer the book Energy Victory to Boston Legal executive producer David E. Kelley. Merry Christmas! (Or happy what-have-you.) Dave, this business about helping out third-world farmers is right up your alley. And I have a sneaking suspicion that making our energy economy dependent on their efforts would do more to help them than we have been able to do so far through clever manipulation of, say, the coffee or brazil nut markets. Plus, you could write one of those heavy-handed closing arguments for Alan Shore (James Spader) to deliver, and for once Denny Crane (William Shatner) would be standing by cheering!

shatner.jpg

I also want to give a copy to whoever it was in the Blog Talk Radio chat room while we were interviewing Robert Zubrin who claimed that ethanol requires more energy to manufacture than it produces. This is another oil-company talking point. Zubrin clearly demonstrates in his book that while this is a valid argument against the 'hydrogen economy," it is utter nonsense when applied to ethanol. Brazil has demonstrated that you can get a net energy gain from ethanol for decades, now. (And I'll throw in another gift copy of the book for the first oil-company stooge who leaves a comment arguing that Brazil is different because they use sugar cane rather than corn.)

Finally, I want to give a copy to Dr. John Marburger, a science adviser to President Bush who is quoted in the book as well as to a member of Marburger's senior staff whose meeting with Zubrin is described in some detail. Zubrin meets with Marburger and outlines how one simple federal requirement -- that all cars manufactured in the US and imported into the US be flex-fuel-capable -- could help us to:

  • Achieve energy independence

  • Break the grip of OPEC on global energy markets

  • Help to de-fund terrorism

  • Drastically decrease carbon emissions

  • Improve economic conditions for some of the poorest of the poor worldwide

Zubrin argues that putting enough flex-fuel cars on the road can create a market for ethanol (not to mention methanol) both of which can free us from dependence on foreign oil. He explains elsewhere in the book that making a car that can run on either gasoline, ethanol, or methanol is not the huge retooling task that most people would expect it to be. You need a recalibrated fuel injection system -- one that responds to whatever mix of gas and alcohol you happen to put into your tank -- and fuel lines that won't break down when exposed to alcohol. That's it. This is well-established technology. Compared to building a hybrid or making a car that you can safely run on hydrogen, this is child's play.

Put enough of these flex fuel cars on the road, Zubrin argues, and gas station owners will have an economic incentive to put in ethanol or methanol pumps. More people buying flex-fuel cars and greater demand for alcohol fuels eventually puts price pressure on OPEC. This economic solution would put the consumers in the driver's seat and would create a competitive environment that would drive down the price of gasoline, ethanol, and methanol. It's a win-win-win.

Marburger's response?

"We don't believe in mandates."

His staffer, when meeting with Zubrin some time later, explained that the costs involved in making the switch to flex-fuel cars would simply be too great for us to bear. Not the cost of actually changing the vehicles -- which apparently he concedes would be minimal -- but the cost of certifying all these new flex-fuel cars. That would cost us a whopping $150 million dollars or, as Zubrin points out, about what the US spends on foreign oil every five hours.

You know, I'm a pretty free-market guy, and Zubrin's solution passes my 80-20 test: 20% of the initiative (or less) needs to come from the government, while 80% (or more) should be market-driven. I haven't seen anything else proposed that comes close to meeting that ratio. The "hydrogen economy" certainly won't.

You would think that a government that "doesn't believe in mandates" would leap at the chance to do something effective that requires so little government involvement. Unless, of course, "we don't believe in mandates" really means "we don't believe in doing anything that will annoy the oil companies," which of course, is another way of saying, "we don't intend to do anything about this at all."

So come to think of it, I don't think I'll waste two copies of the book on Marburger or his staff member. I think there must be some other folks out there who would benefit more from reading it. Please feel free to leave suggestions in the comments area as to who I should give the book to.

And don't forget to buy your own copy:

Fueling the Future

Ronald Bailey has written an interesting article weighing our future fuel options. The problem - our green alternatives aren't cheap enough and the cheap alternatives aren't green. He's not impressed by ethonol or hydrogen.

He is excited by next generation (nanotech engineered) lithium ion batteries. Also:

Biotechnology is another possible pathway to a post-petroleum future. For example, the privately-held biotech company, LS9, based in San Carlos, CA. aims to use synthetic biology to skip over ethanol to directly produce gasoline. LS9 co-founder and Harvard University geneticist George Church describes synthetic biology as "treating biology the way you would treat large-scale integrated circuits. We've been dealing with one part at a time or a small number of parts. Synthetic biology is engineering of new systems using parts that we trust." Another way to think about it is that biologists want to do to biology what engineers have done to electronics and chemists have done with chemistry.

I had similar thoughts back in June.

The Golden Ticket

As luck would have it, my cobloggers Phil, Kathy Hanson, Michael Sargent, Ben Young and I all won golden tickets to tour the super-secretive EEStor factory in Cedar Park, Texas.

As we arrived we gathered just outside the huge iron factory gate. After what seemed an eternity, the gate swung open and we were all greeted by diminutive orange teamsters and the factory's elusive caretaker Richard Weir.

OompaLoompas1971 small.JPGThroughout the day we toured a wonderland of futuristic paradigm-altering technology. But, strangely, our party kept shrinking. Michael's incessant gum-chewing, Ben's handheld television, and Kathy's nonstop shouting "But I want a supercapacitor NOW!" caused them all to be asked to step away from the tour. And those tiny workers seemed weirdly disappointed that the new Phil wasn't tempted by the river of chocolate at the lunch buffet.

Phil would have made it to the end of the tour, but he got sidetracked by the Fizzy Lifting Flying Car Project (FLFCP).

Only I, being pure of heart, was allowed to see the entire factory...


Okay. Obviously frustration has sent me a little over the edge. Is EEStor about to change the world, or is this all an elaborate tease? Since January we've been waiting for EEStor to deliver their supercapacitors for use in ZENN electric cars. If what they've claimed is true, it will be a real game changer:

The Achilles heel of [currently available] ultracapacitors is their specific energy density -- they don't hold nearly as much energy per unit weight as batteries. Lithium ion batteries produce around 120 watt hours per kilogram, whereas commercially available ultracapacitors produce around 6 Wh/kg, some 20 times less. That won't cut it for vehicles, much less for industrial-grade renewable energy storage.

...

[But EEStor] system claims a specific energy of about 280 watt hours per kilogram, compared with around 120 watt hours per kilogram for lithium-ion and 32 watt hours per kilogram for lead-acid gel batteries.

Forget hybrids, if EEStor delivers this, we'll all jump straight to 100% electric vehicles. Supercapaciters are environmentally clean, charge as fast as you can fill a tank with gasoline, and would be cheap to operate.

EEStor has not produced (at least for the public) a working prototype. Perhaps they're worried about the Slugworth's of the world who could steal their invention. But they do have a patent. Comeon guys, show your cards!

Maybe they don't feel the need to demonstrate their technology because they have sufficient investment already. ZENN Motor Company has invested $3.8 million and the venture capitalist firm Kleiner, Perkins, Caufield & Byers (known for wise early investments in Google and Amazon) has invested another $3 million.

These high-end investors must know more than the public. But other critics are publicly doubtful that EEStor's announced breakthrough is even technically possible.

I remain hopeful and optimistic because the guys that founded EEStor have a good track record. When a prototype is delivered we will learn either that EEStor is living in a world of pure imagination, or that we've all got a golden ticket.

Welsh Fishing Buddies Save the Planet

All right, really they're an organic chemist and a couple of engineers. But they got the idea for their Greenbox -- a device that captures a vehicle's carbon emissions and stores them for eventual processing as biofuel -- while fiddling around with carbon dioxide in order to grow algae as apart of a fish-farming project.

greenbox.jpg

If the system takes off, drivers with a Greenbox would replace it when they fill up their cars and it would go to a bioreactor to be emptied.

Through a chemical reaction, the captured gases from the box would be fed to algae, which would then be crushed to produce a bio-oil. This extract can be converted to produce a biodiesel almost identical to normal diesel.

This biodiesel can be fed back into a diesel engine, the emptied Greenbox can be affixed to the car and the cycle can begin again.

The process also yields methane gas and fertilizer, both of which can be captured separately. The algae required to capture all of Britain's auto emissions would take up around 1,000 acres.

Seems like a technology such as this -- if it pans out -- could be a big helping in cutting emissions during the long transitional phase from gas-powered vehicles to hybrids to plug-in hybrids to fully electric vehicles. And then once we're fully electric, all we need is something to power the electric grid.

More squishy green algae goodness here.

Is Heat a Resource?

…apparently so. Utah physicist Orest Symko has developed a way to turn waste heat into sound which is then converted into electricity.

"It is a new source of renewable energy from waste heat."

...

Using sound to convert heat into electricity has two key steps. Symko and colleagues developed various new heat engines (technically called "thermoacoustic prime movers") to accomplish the first step: convert heat into sound.

Then they convert the sound into electricity using existing technology: "piezoelectric" devices that are squeezed in response to pressure, including sound waves, and change that pressure into electrical current. "Piezo" means pressure or squeezing.

...

Devices that convert heat to sound and then to electricity lack moving parts, so such devices will require little maintenance and last a long time. They do not need to be built as precisely as, say, pistons in an engine, which loses efficiency as the pistons wear.

...

The research is funded by the U.S. Army

speculist dune.JPGSymko thinks that these devices can be shrunk for use in laptop computers. They could reduce heat and extend battery life at the same time. Also he thinks they might be used as an alternative method for getting electricity from sunlight. You could put these devices in a small greenhouse box on your roof and plug in. No word yet on whether this could provide more electricity per dollar invested than photovoltaic cells.

If our country moves to hybrid vehicles, why not use our hot cars to charge those lithium ion batteries? Both engine heat and cabin heat could be used. We southerners could get some serious mileage out of cabin heat. Just sitting in the parking lot my truck typically gets over 120 degrees Fahrenheit in August.

The interim sound step is important. It serves to organize the energy in preparation for a conversion to electricity:

"You have heat, which is so disorderly and chaotic, and all of a sudden you have sound coming out at one frequency," Symko says.

And they won't drive us crazy with their noise:

Symko says the devices won't create noise pollution. First, as smaller devices are developed, they will convert heat to ultrasonic frequencies people cannot hear. Second, sound volume goes down as it is converted to electricity. Finally, "it's easy to contain the noise by putting a sound absorber around the device," he says.

100 MPG

Enough about the X-Files. Let's talk about the X Prize...the automotive X Prize, that is. From Slashdot:

The [X Prize] Foundation now plans to offer millions for the first practical car that increases mileage five-fold. The specs for the competition are out in draft form amd call for cars in two categories that are capable of 100 MPG in tests to be run in 2009. The categories are: 4-passenger/4-wheel; and 2-passenger/unspecified wheels. The cars must be manufacturable, not "science projects. The prize is expected to top $10 million. The X Prize Foundation says that so far it has received more than 1,000 inquiries from possible competitors.

More info here. The requirement that it be a truly manufacturable car is important. On the other hand, a 100 mpg car doesn't have to be all that cheap compared to a 20 mpg car. There's plenty of room to make that extra cost up on the back end.

The winning entry will almost certainly be a hybrid, but what kind? We've spent a lot of time pondering hybrids at the Speculist. Stephen is a big fan of plug-in hybrids. Personally, I don't think enough attention has been paid to hydraulic systems which "recycle" braking into acceleration. Who knows? The winner might exploit more than one of these ideas.

Then again, there was this tidbit on L2si the other day:

If this guy is legit, he may deliver the environmentally friendly Hummer that I asked for on the most recent FFR.

March 30, 2007


Wacky Energy Sources

Pond scum is only the beginning. Over on L2si, you've got your choice of wacky energy sources: do you want power from sugar or power from water? If it works, I think the latter will be the way to go.

But that's a fairly sizable "if."


High Hopes for Pond Scum, Part 2

Yesterday Popular Mechanics published an article on commercial algae production. The key points:

  • Algae produces oil. Lots of it. Up to 50% of the volume of algae is oil that can be directly converted into biodiesel. The carbohydrate content can be fermented into ethanol (or a really strange martini). Both biodiesel and ethanol are environmentally friendly fuels. After harvesting these two fuels, the remaining plant bulk - mostly protein - can be used in feed stock.

  • Algae is subject to exponential growth under the right conditions. It can double its volume in a day. Therefore, it can be harvested everyday. This sets it apart from every other biodiesel crop. Algae is expected to produce 10,000 gallons of oil per acre per year. The next best biofuel crop - palm - produces 650 gallons per year per acre.

  • If we had to grow all our country's diesel this way, it could be done "on an area of land that’s about one-half of 1 percent of the current farm land that we use now."

  • Algae grows well in brackish water. This could be particularly useful in the deserts of the American southwest. Much of the available ground water there is salty.

  • The startup company that is featured in this article is moving forward quickly:

    Solix plans to complete its second prototype by the end of April and to begin building a pilot plant this fall. That plant will take advantage of CO2 generated from the fermentation and boiler processes of New Belgium Brewery, also in Fort Collins. The company’s initial target is to be competitive with biodiesel, which historically sells for about $2 per gallon, wholesale. They believe they can reach this goal within a few years, and are ultimately aiming to compete with petroleum.

Here's my original March 11 "Pond Scum" post. And, don't miss the FastForward Radio discussion on this topic.

March 16, 2007


Another Possibility for CO2

My last post on commercial algae production mentioned the importance of CO2. Without additional CO2 - in densities greater than what's found in the atmosphere - algae farms would not be commercially viable.

There may be another way to get energy from CO2. The Max Planck Institute has developed a catalyst that breaks the stable CO2 bond much like algae and other plants.

In photosynthesis, the CO2 molecule is initially bonded to nitrogen atoms, making reactive compounds called carbamates. These less stable compounds can then be broken down, allowing the carbon to be used in the synthesis of other plant products, such as sugars and proteins.

In an attempt to emulate this natural process, Goettmann and colleagues Arne Thomas and Markus Antonietti developed their own nitrogen-based catalyst that can produce carbamates. The graphite-like compound is made from flat layers of carbon and nitrogen atoms arranged in hexagons.

The team heated a mixture of CO2 and benzene with the catalyst to a temperature of 150 ºC, at about three times atmospheric pressure. In a first step, the catalyst enabled the CO2 to form a reactive carbamate, like that made in plants.

The catalyst's next useful step was to enable the benzene molecules to grab the oxygen atom from the CO2 in the carbamate, producing phenol and a reactive carbon monoxide (CO) species.

From there it is relatively easy to refine fuel. When oil supplies were limited during World War II, Nazi Germany made fuel from carbon monoxide derived from coal.

Now these researchers are attempting to further increase efficiency by using light as the energy source to split CO2 - again, like plants.

It seems that one way or another, excess CO2 will be less a problem than a solution.

March 12, 2007


High Hopes for Pond Scum

In our last FastForward Radio show Phil and I discussed the possibility of oceanic plankton being used to sequester the greenhouse gas carbon dioxide. As an aside I mentioned that plankton makes a good bio-diesel. In other words, we could get a twofer out of the deal. We sequester carbon AND we harvest some of the plankton for energy.

It's not a bad idea, but ramping up a major offshore project with unproven technology would be difficult. Fortunately there is an easier way to get started. Last week The New York Times published an article about a related venture:

A few companies are in a race to be first to convert [freshwater] algae to fuel on a commercial scale, and it will require not a small amount of money, luck and biotech tweaking…

[The goal] is to find an energy-efficient way to convert algae into fuel [pdf link], which is why she [Venture Capitalist Lissa Morgenthaler-Jones] was visiting a catfish farm here that was for sale. Farmed catfish could provide a useful source of carbon dioxide for the algae, as well as a critical revenue flow to keep research going…

By comparison to plankton, algae is lower hanging bio-diesel. Working onshore would eliminate much risk - to people and to the project. And lessons learned could further offshore plankton projects later.

According to the US Department of Energy, algae can produce more bio-diesel than any other plant. Algae doesn't have to waste energy drawing water and nutrients from the ground. Algae's advantage is that it is suspended in the aqueous solution of the carbon dioxide and nutrients it needs to grow.

Using catfish as a source of CO2 helps in a small-scale experimental pond, but commercial algae production would not be huge catfish farms. On larger scales catfish would be more of a distraction than a revenue source. Scientists are recommending using the desert:

Geothermal activity under the desert could provide a free source of carbon dioxide to bubble up for the algae to absorb and convert into organic matter to process as fuel...

"If the U.S. put 15 million acres of desert into algae production, we could produce enough volume of liquid fuels to get us off the Middle East oil addiction and give Iowa back to the songbirds," said B. Gregory Mitchell, an algae research biologist at the University of California , San Diego, who is a friend of Ms. Morgenthaler-Jones and Mr. Jones.

Gregory Mitchell's calculation is based on a theoretical production of 20,000 gallons of bio-diesel per year per acre of algae.

One requirement that would be in short supply in the desert is water. It would have to be piped in from elsewhere. Perhaps algae wouldn't require potable water. Runoff water and even sewage from desert cities like Las Vegas and Phoenix might be usable. Such water would have to be treated because algae ponds are subject to contamination which would reduce bio-diesel yields.

Obviously there is much work to be done. But if we can do this we would be harnessing desert solar power and CO2 for our energy needs.

Brewing the Future

Almost two years ago I wrote about a certain self-replicating nano-machine that works at the nano-level and quickly produces macro-level results. This machine is yeast.

Yeast hasn't eaten the world Grey Goo style because they either die of starvation (because they quickly eat all sugar in their area) or they are poisoned by the product of their work – alcohol.

This fact - that yeast is killed by alcohol - places an upper limit on the amount of alcohol in beer and wine. If you want something much stronger than 10% alcohol, it will have to be a distilled beverage.

Brewers have been working with yeasts for generations to bred yeasts that can produce higher concentrations of alcohol. In an effort to improve the efficiency of ethanol production (ethanol being simply an alcohol we can burn in our cars), a group at MIT has joined this effort with their own super-yeast:

The work by MIT chemical-engineering professor Gregory Stephanopoulos and his colleagues focuses on the second part of this process: fermenting sugars to make ethanol. The yeast strain they made can tolerate ethanol concentrations as high as 18 percent--almost double the concentration that regular yeast can handle without quickly dying. In addition, the new strain makes about 20 percent more ethanol by processing more of the glucose, and it speeds up fermentation by 70 percent.

H/T to FuturePundit.

Futurepundit Randall Parker points out that this will result in an exponential improvement in efficiency because each fermentation produces more ethanol, AND isolating that ethanol will require less distillation.

These researchers also want to genetically engineer the yeast to break down cellulose into simple sugars. Then yeast could perform the two biggest steps in making ethanol from biomass…

Ethanol is less than ideal as a liquid fuel because it has much less energy per gallon than gasoline.

True, but a plug-in hybrid vehicle could probably be engineered to get acceptable range and power burning pure ethanol. This could potentially be a step toward energy independence.

Of course if we get an 18% alcohol beer, we'll need autodrive on those cars.


UPDATE: Okay... ethanol IS the alcohol found in alcoholic beverages. No difference - except that the ethanol put in gasoline is "denatured" - made unfit for human consumption. You want people topping off their cars at the pump, not their flasks.

More info from wikipedia:

Ethanol creates very little pollution when being burned... Pure ethanol has a lower energy content than gasoline (about 30% less energy per unit volume).

A clean burning fuel with 70% of the energy of gasoline. Yeah, a plug-in hybrid could work.

Cheap, Abundant, Distributed

Last week Glenn Reynolds' Internet model for air travel was all the buzz. All well and good, but how about a similar model for nuclear power? Michael Anissimov outlines a plan for safe, cheap, abundant energy -- this is a plausible, relatively near-term solution. Exciting stuff.


Plus, it's the very infrastructure that can help us gear up to our Helium 3 endgame.

August 20, 2006


Extreme Measures

FuturePundit Randall Parker outlines Brazil's successful ethanol program, which has now replaced an impressive 40% of the gasoline consumed in the country. Unfortunately, he goes completely off the rails when he gets on the subject of trade barriers that prevent Brazilian ethanol from being imported into the US:

I feel compelled to digress again into trade politics but only because I have a really great idea for Brazil. My advice to the Brazilians: Stop letting any of your models come to the US and pose in Victoria's Secret catalogs until the US government agrees to let in Brazilian sugar and sugar cane ethanol. American citizens might tolerate having to pay more for Breyers than Dreyers in order to get sugar rather than corn syrup as ice cream flavoring. But American men will only find the backbone they need to stand up to the corn farmers and ADM when they find out that the farmers are preventing them from looking at Gisele Bündchen, Michelle Alves, Shirley Mallmann, Isabeli Fontana, Fernanda Tavares, and Ana Beatriz Barros.

Whoah, whoah, whoah...slow down there, son. Take a breath. Let's not do anything rash, okay? I mean, come on.

It's just ethanol.

Where is your sense of proportion?

UPDATE: I replicated Randall's links without checking on whether they were completely work / kid safe. I think they're pretty much okay. I mean, anybody who doesn't approve of that Gisele Bündchen photo must just hate art or horses or something.

UPDATE II: Looks like they swap those photos out every now and then, so never mind about the horses.

Hydrogen Hybrids

Will Brown directs us to this site, where they sell kits that you can use to convert your existing car into a gas / hydrogen hybrid. It's a very interesting model.

In keeping with our discussion on economic disruption, these kits enable you to collect your own hydrogen. Hydrogen is extracted from the atmosphere via solar power. Free fuel! Plus, if you don't collect enough -- or say if you need to go on a long trip -- you can always switch back to burning gas.

hydro.jpg
Answer to the problem of gas proces?

There are bound to be numerous objections to and problems with this approach. I was a bit alarmed by the presence of the tanks reading DANGER! HYDROGEN! stacked on each other in the back of the car, but apparently the hydrogen gas is bonded to a metal and stored in an inert state. (I guess the warnings are only there in gas the gas begins to leak out for some reason, although I'm not clear on how that coul happen.)

Anyway, with what it's costing me to fill the Jeep these days, I certainly like the idea of collecting fuel for free in my back yard.

May 02, 2006


More on Alternative Energy

What, nothing about black holes as an alternative fuel source? Oh, well...go ahead and listen to the Glenn and Helen Show's interview with Jim Meigs from Popular Mechanics, anyhow.

It's not like I'm accusing them of selling out or anything. Or suggesting that Popular Mechanics is just a front for the powerful anti-black-hole lobby.

Heavens, no.

CLEVER

It stands for "Compact Low-Emission Vehicle for Urban Transport:"

The prototype, a skeletal speedster which had safety netting in place of body panels, exhibited the general design and technology of the vehicle rather than its actual, finished appearance.

It has the compactness of a motorcycle but the safety of a car, and cornering is smoothed by a tilting technology developed by mechanical engineering students Matt Barker, 29, Ben Drew, 27 and their instructors.

clever.jpg

I've been wondering for some time why somebody doesn't build a car-like frame around a motorcycle. Motorcycles get great gas mileage, but they tend to be invisible to some of the less...attentive drivers out there. This would be as visible as any small car and it gets 108 miles to the gallon.

Who needs a hybrid?

April 26, 2006


But How Would We Tap In?

High gas prices are the problem. Black holes are the unlikely ultimate answer:

A new study finds that the supermassive black holes at the hearts of some galaxies are the most fuel efficient engines in the universe.

"If you could make a car engine that was as efficient as one of these black holes, you could get about a billion miles out of a gallon of gas," said study team leader Steve Allen of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University. "In anyone's book, that would be pretty green."

Granted, we probably won't really be harnessing them to power automobiles. But they've got to be good for something: probably enormous engineering projects a century or two down the road that we can only vaguely conceptualize at this point.

The article goes on to make the rather offbeat point that black holes are also "green" in the role they play in preventing the galacgtic version of urban sprawl -- by basically sucking everything in the vicinity in and annihilating it all.

Er, okay. Pretty handy, huh?

UPDATE: Meanwhile, here's the low-down on some less exotic energy alternatives.

February 26, 2006


Distribution

"The future is here, it's just not evenly distributed."

- quote commonly attributed, probably incorrectly, to William Gibson.


"Our nation is on the threshold of some new energy technologies that I think will startle the American people. It's not going to startle you here at Johnson Controls because you know what I'm talking about. (Laughter.) You take it for granted. But the American people will be amazed at how far our technology has advanced in order to meet an important goal, which is to reduce our imports from the Middle East by 75 percent by 2025, and eventually getting rid of our dependence totally."

- President Bush, February 20, 2006


It's gratifying to see the President finally addressing this important front in the War on Terror. If we are less dependent on trouble spots for energy, then the amount of misery we will feel compelled to put up with will be less, and the money that malevolent oil dictatorships will have to do us harm will be less too. A win, win. A triple win if you consider the environment. Most alternative forms of energy reduce pollutants, including green house gases.

The President said,

The most promising ways to reduce gasoline consumption quickly is through hybrid vehicles. Hybrid vehicles have... an electric battery based on technologies that were developed by the Department of Energy... [T]his technology came to be because the federal government made a research commitment...

Research paid off in the past, so let's try it again. The President suggests "a 22 percent increase in funding for clean energy research at the Department of Energy."

Future Pundit Randall Parker has an excellent analysis of Bush's speech, why it's important, and why it doesn't go far enough:

Bush is getting over the original obsession of his Administration on hydrogen and seems to be realizing that development of better batteries is a highly desirable and achievable goal. Well, better that political leaders learn late than never.

Bush even seems to be aware that switch grass would be better than corn as a biomass source of energy. We need better technology for converting the cellulose in the switch grass into more usable sugars. But that's a solvable problem.

...

I do not think Bush's recent speeches on energy are a huge step forward. A huge step forward would put a couple billion dollars a year into solar research, a couple billion into batteries, maybe a billion into accelerating pebble bed nuclear reactors or other advanced reactor concepts, and still other initiatives. These initiatives should be on a scale similar to the corn ethanol boondoggle [$3 billion per year] but in productive directions rather than aimed at satisfying farmers and Archer Daniels Midland.

Agreed. And how about setting aside about 10% of that budget for energy push prize programs?

February 19, 2006


Is He Serious?

President Bush is talking about moving ahead with nuclear power:

WASHINGTON -- President Bush on Saturday renewed his push for expansion of nuclear energy and sought support for plans to revive nuclear-fuel reprocessing to deal with radioactive waste from commercial power plants.

The President's take on our energy future is summed up as follows:

"The best way to meet our energy needs is through advanced technology..." .

That's a refreshing statement. I hope he means it. Whether we pursue a renaissance of nuclear power as the best means of kicking off the hydrogen age, or as moving us towards something more exotic, or as a freeing-us-from-foreign-oil end unto itself -- or even if we skip nuclear power altogether in favor of something more productive, more exciting, whatever -- the solution to our energy problems lies in technologies not yet perfected or possibly even conceived. And I don't exclude from that list technologies that allow us to use petroleum more efficiently or extract it from places where we haven't before.

Put another way, existing energy technologies -- on their own -- are not going to cut it. So much of the thinking that takes place in the political sphere, where energy is concerned, is predicated on existing technologies and usage patterns or, at best, linear extrapolations therefrom. This kind of thinking leads to zero-sum-game realpolitick whereby we identify countries like Saudi Arabia as our "friends." It also provides the rationale for those who claim that the US interest in Iraq must be primarily about the oil.

New technologies, whether they involve a refurbished approach to nuclear power or something else altogether, give us options that existing technologies can't. This is the piece of the puzzle that's often missing in the global warming debate. The Kyoto Protocoal requires participating countries to cut emissions by...cutting emissions. The assumption is that the primary means of doing this is to reduce energy use. As the Wikipedia article on the subject explains it:

The Kyoto Protocol limits emissions to a percentage increase or decrease from their 1990 levels. Since 1990 the economies of most countries in the former Soviet Union have collapsed, as have their greenhouse gas emissions. Because of this, Russia should have no problem meeting its commitments under Kyoto, as its current emission levels are substantially below its targets.

A more dynamic approach would be an international treaty requiring participating nations to reduce emissions without reducing energy use. Such an agreement would not reward economic failure, which is what Kyoto does -- whether intentionally or inadvertantly. Instead, it would presuppose the need to keep economies developing and, more importantly, the need to find non-emission-producing energy technologies.

Ultimately, it's all about the questions we ask. If we ask "How can we get more oil?" and "How can we reduce greenhouse emissions?" we get one set of answers. If we ask "What alternatives do we have to oil?" and "How can we reduce greenhouse emissions while increasing the amount of available energy?" we get another set of answers.

Energy Race Update

Russia wants in on "the energy race" too.

We are planning to build a permanent base on the moon by 2015 and by 2020 we can begin the industrial-scale delivery... of the rare isotope Helium-3," Nikolai Sevastyanov, head of the Energia space corporation, was quoted by ITAR-TASS news agency as saying at an academic conference.

The International Space Station (ISS) would play a key role in the project and a regular transport relay to the moon would be established with the help of the planned Clipper spaceship and the Parom, a space capsule intended to tug heavy cargo containers around space, Sevastyanov said.

January 26, 2006


The Energy Race

A couple of days ago China announced plans to complete its tokamak fusion reactor by April of this year. China will start experimenting with the reactor - designated HT-7 - this summer with the hope of hitting a magic breakeven point that has, to date, never been reached in fusion research anywhere. They hope to produce more power than is required to contain the reaction.

Tokamak is a Russian acronym meaning "toroidal chamber in magnetic coils." A tokamak reactor contains a giant donut-shaped magnet used to contain plasma within the reactor.

The United States has been betting on the success of a different tokamak project: the International Thermonuclear Experimental Reactor (ITER). The ITER has been in the design and planning phase so long (since 1985!) that China may have already leap-frogged the rest of the world with its cheaper reactor.

...Construction [on ITER] is expected to begin in 2008 and finish in 2016. ITER is designed to generate 500 MW (about 10 times the record held by JET) and will hopefully produce more energy than is required to keep the plasma heated and confined...

Which will mean little if China has already accomplished this with a reactor that cost 1/20th the price of the ITER.

Tokamak reactors are powered by deuterium harvested from seawater.

After nuclear fusion, the deuterium extracted from one liter of sea water will produce energy equivalent to 300 liters of gasoline.

This would be a practically inexhaustible supply of power, and China probably has the lead in deuterium fusion research at the moment. Maybe the U.S. will compete with a different form of fusion.

[Deuterium fusion critics] have noted that the neutrons released in the deuterium-tritium fusion would create secondary radiation within the metallic parts of the reactor chamber. This secondary radiation would create radiological waste disposal problem, and would also shorten the life of the components in the reactor through radiative metal fatigue...

If China gets their reactor working, it won't be easy to operate or maintain. Fortunately, there is the possibility of a cleaner, easier to manage fusion fuel.

[Twenty years ago fusion expert Gerald Kulcinski] and a group of scientists met at a retreat south of Madison, Wisconsin to discuss the problems with the deuterium-tritium fuel cycle for fusion. They talked over what the options are for a better fuel. Helium-3 is what they came up with.

In fact, helium-3 is the perfect fusion fuel. It can produce an incredible amount of power with absolutely no radioactivity. And a helium-3 fusion reactor won't have the same containment issues either.

Professor Kulcinski's lab is running the only helium-3 fusion reactor in the world. He has an annual research budget that is barely into six figures and allows him to have five graduate research assistants working on the project. Compared to what has been spent on other fusion projects around the world, the team's accomplishments are impressive. Helium-3 would not require a tokomak reactor like the multibillion-dollar one being developed for the international ITER project. Instead, his design uses an electrostatic field to contain the plasma instead of an electromagnetic field.

There's a catch. Unlike the deuterium, which can be obtained from the ocean probably forever, there are only a few hundred kilograms of helium-3 on Earth. You have to go to the Moon to find helium-3 in useful quantities.

In January of 1986 Professor Kulcinski and his group contacted the Lunar and Planetary Institute at the Johnson Space Center. The soil samples from the Apollo missions are stored there. Every sample from the Moon had helium-3 in it. It didn't matter if the sample was collected from right on the surface or from a core sample a meter deep...

Theoretical calculations of helium-3 abundances on the Moon suggest that it may have enough to supply current world energy demand for thousands of years. Even further out, the gas giant planets contain enough helium-3 to power human civilization for millions of years.

In the short run deuterium will be seen as the miracle fuel. We certainly have plenty of it right here at home. But it will wear out reactors and leave us with some nasty radioactive waste. Ultimately we will turn to helium-3 because it is abundant (if you look in the right places), safe, and manageable.

Alternative Energy...

...is civil defense. Or so says Engineer Poet. Some good thoughts, there. Check it out.

Hydrogen Car Update

Engineer Poet provides a withering analysis of the potential viability of the car that produces its own fuel about which we recently wrote. It looks as though the efficiency just isn't there.

Good to know. However, I must take issue with EP's conclusion:

Forget Hydrogen!

Surely that's a little extreme? After all, it's the most abundant element in the universe. It's got to be good for something.

UPDATE FROM STEPHEN:

EP is right that energy is lost using hydrogen in a hydrogen fuel cell to produce electricity.

But this Engineuity concept car would use the hydrogen extracted from water in an internal combustion engine - exploding it like gasoline or diesel under pressure.

Also, there doesn't appear to be significant loss of energy from heat because the heat is recycled to aid the electrolysis - am I right about this heat recycling? Someone with a engineering background needs to study that schematic on this point.

Anyway, EP may be right about hydrogen fuel cells, but this is a different idea.

UPDATE II:

The original IsraCast article now has an audio interview of project leader Professor Amnon Yogev.

According to the interview, reclaiming heat energy is a very important part of this concept. According to Yogev:

If you don't find a way to use the heat...actually you reject half of the energy.

October 25, 2005


Sounds too good to be true

...but then again, I've often wondered if there wasn't a solution like this sitting out there somewhere waiting for someone to find it:

A unique system that can produce Hydrogen inside a car using common metals such as Magnesium and Aluminum was developed by an Israeli company. The system solves all of the obstacles associated with the manufacturing, transporting and storing of hydrogen to be used in cars. When it becomes commercial in a few years time, the system will be incorporated into cars that will cost about the same as existing conventional cars to run, and will be completely emission free.

From reading the full article, it sounds as though the car will actually require two fuel sources -- water and a very heavy metal coil which enables the production of free hydrogen by producing metal oxide (what folks like us call rust, one presumes) as the by-product of running the engine. Apparently the driver would need to put water in the tank on a par with putting gas into the fuel tank of a conventional vehicle. How long the coil lasts is not stated, but seeing as it weighs 100 Kg, one would hope that the driver won't need to go sticking in a new one every week.

UPDATE: Plenty of healthy skepticism about this over at SlashDot, where I got the link to the cover story of the latest New Scientist -- Metal: The Fuel of the Future.

Hard Math

Getting back to non-conventional fuel sources, the argument is often made that ethanol can't really work as a fuel source, seeing as ethanol fuel in the U.S. is actually produced at a net loss of energy. That doesn't seem to be the case in Brazil.

Maybe sugar provides more robust alochol production than grain does. Or Maybe the Brazlians know something we don't?

Kentucky Fried Jeepin'

In the interests of fuel economy, I've been thinking about trading in my 2002 Jeep Liberty for one of the new diesel models. But now this article in The Smithsonian (via SciTech Daily) really has me thinking. Consider these two use-cases:

Every few weeks, Etta Kantor goes to a Chinese restaurant and fills a couple of five-gallon pails with used cooking oil. Back in her garage, the 59-year-old philanthropist and grandmother strains it through a cloth filter and then pours it into a custom-made second fuel tank in her 2003 Volkswagen Jetta diesel station wagon. Once the car is warmed up, she flips a fuel toggle on the dashboard to switch to the vegetable oil. Wherever she drives, she’s trailed by the appetizing odor of egg rolls.

Sean Parks of Davis, California, collects his cooking oil from a fish-and-chips restaurant and a corn-dog shop. He purifies it chemically in a 40-gallon reactor that he built himself for about $200. The processed oil can be used even when his car's engine is cold, at a cost of about 70 cents a gallon. Parks, 30, a geographer for the U.S. Forest Service, makes enough processed oil to fuel his family's two cars.

The article goes on to point out that the grease running through all the deep fryers in all the restaurants and fast food joints in the US could be used to make about 100 million gallons of biodiesel fuel annually, which could meet about 5% of our national fuel consumption needs.

kfcjeep.jpg


What's most impressive to me about the adoption of this energy source is that apparently some folks don't feel the need to wait for biodiesel to be offered at their neighborhood Shell station before they start using it. They're adjusting their vehicles and finding the fuel themselves.

The article concludes:

Grass-roots fans aren't waiting. Kantor, who paid $1,400 to outfit her VW diesel with a second fuel tank, says she gets nearly 200 miles per petrodiesel gallon. "This is not about money," says Kantor, who speaks at schools about protecting the environment. "I'm doing this to set an example."

Well, 200 MPG sounds pretty darn good. I doubt a modified Jeep would be quite as fuel efficient as a modified Jetta, but still.
Even at 150 miles per gallon, that would be 8-9 times better than the mileage I'm currently getting. And there's a hot wings place just right up the street (with a McDonald's and a Popeye's along the way.)

Hmmmm.......

UPDATE: Well, our friends J Random American and Engineer Poet didn't waste much time in totally raining on my hot-wings-Jeep parade (see comments, below.) However, J's cat diesel idea has me thinking that maybe we shouldn't just be thinking of running the Jeep on chicken grease. The chickens themselves would appear to be a good option. Of course, if we really want to get a meme going, maybe we should crunch the numbers on how much fuel we could get from puppies. I can think of at least one prominent blogger who might be intrigued.

On a more serious note, J points out some very real economy of scale objections to these gimmicky fuel sources. Read the whole thing.

To Plug or not to Plug...

The October issue of Popular Mechanics has an article (not available online) entitled, "Fueling the Future." The article highlights five emerging energy technologies:

  1. Next Generation Wind Power

  2. Plug-in Hybrid Vehicles

  3. Cleaner Fusion

  4. Ocean Wave Energy Buoys

  5. Microbial Fuel Cells

  6. Organic Solar Cells

All of these ideas are worth a post. But I'm particularly glad that the idea of plug-in hybrids is getting some mainstream attention. This article states that most Americans drive an average of 30 miles a day. According to Dr. Andrew Frank of the University of California, an electric engine that's recharged nightly could handle all of those miles. And unlike all-electric vehicles, there is no range issue. The car's gasoline engine will kick in if the battery gets low or if high speeds are required. We have the gasoline infrastructure in place to allow these vehicles to take long trips.

The primary reason carmakers appear to favor the "charge-sustaining" approach is convenience. They don't think drivers will want to be bothered with having to plug in their vehicles when they come home at night, which the "charge-depletion" approach requires.

Well, that's kind of silly. If the owner of a plug in hybrid doesn't want to plug in, he doesn't have to. It's only an option. Such a car would be no different from the hybrids on the road today. They run primarily on gas, but use some electric power harvested from braking. Dr. Frank:

"We are also working on automating the charging. The only thing that is required for you to do is that you park in the same place every night. You park the car, you take the key out, you hear a little click underneath the floor and the car is on charge, automatically."

Dr. Frank believes that plug-in hybrids could become a stepping stone to other fuel sources like hydrogen. He imagines a plug-in hybrid hydrogen fuel cell vehicle.

Bigger Than Oil

Late last month columnist Michael Ventura wrote a remarkable horror story about America’s future for the Austin Chronicle.

oil-rigsmall.gifApparently America is doomed because of rising oil prices. Nice of Ventura to let us know. Gives us a chance to plan for the whole mediocrity gig. Ventura’s article is well written, logical....and quite wrong. I invite you to read the whole thing and return here for the pep talk you’ll need after reading it.

Ventura has decided, with some relish it seems, that America will cease to be a superpower. I don’t disagree with his outline of our challenges. While his timetable seems accelerated, I don’t doubt that the price of petroleum is going to skyrocket in the coming years. Output has probably peaked, while our demand in this country continues to climb. And the colossus developing economies in China and India will soon be competing for a larger share of this resource.

Ventura’s logic fails in two respects. First, he is considering America’s challenges without also considering what we have going for us. Also, Ventura is working from the hypothesis that the U.S rose to power solely because of oil. By gobbling up this resource, this thinking is, the United States became a hyperpower. Of course petroleum did fuel our rise to dominance, but petroleum is a world resource. Our country was able to demand a lion’s share of this resource because we were already set up to succeed and other societies were set up to fail.

In 1998 Ralph Peters wrote, “National success is eccentric. But national failure is programmed and predictable.” He then outlined seven “failure factors” - the reasons why societies fail. They are:

  • Restrictions on the free flow of information.

  • The subjugation of women.

  • Inability to accept responsibility for individual or collective failure.

  • The extended family or clan as the basic unit of social organization. (rather than being able to hire the best person for the job, the job must go to never-do-well second cousin Herb)

  • Domination by a restrictive religion.

  • A low valuation of education, and

  • Low prestige assigned to work.

A country will suffer if any of these factors become part of its culture. If the culture is able to self-correct, it will improve its chances for success - every time. But often societies are ideologically committed to a failure factor - as China is to the restriction of information and the Islamic world is to...all of these factors. Societies burdened with failure factors have an impossible time keeping pace with countries that aren't.

The failure factors are sliding scales. If we were to assign "10" as the perfect score for each category, the United States would not score 70. But historically we have valued liberty for individuals and accountability in leadership. It was thought that such a system would maximize individual happiness. It has certainly done that, but it has also produced a remarkably powerful country. Right makes might.

The United States is also the beneficiary of remarkable network strength. Of course there's the country itself. The United States is a huge free trade zone dominated by a single language and few barriers to commerce. Canada and Mexico were brought into this network with NAFTA. And soon, Central America will be brought into the economic network with CAFTA. And America's social and economic sphere of influence is global.

But let's assume that Ventura is right about petroleum slipping away. It won't be gone so much as prohibitively priced - priced to the point that we have to limit our energy consumption or find a new source of energy.

I’m betting on the new source of energy.

This is not just blind optimism. There’s accelerating development in every field of human knowledge. Moore’s law keeps delivering faster processors, which provide us the power to accomplish more intellectually in a shorter period of time than ever before.

Speaking of network strength, the Internet isn't going away. The Internet provides a way for knowledge workers to work anywhere - even in those suburbs and rural areas that Ventura thinks are going to become backwater ghettos. Telecommuting has been limited to a great extent because people are still expected to come into an office. Expectations may change with $6.00 per gallon gas.

The Internet also provides instant and universal access to the world of knowledge. It will be instrumental in helping scientists find a petroleum replacement.

What will replace petroleum? Hydrogen suffered a set-back recently when the National Academy of Engineering concluded that, if achievable, a hydrogen economy is “several decades” away.

"Several decades" has a way of becoming one decade if sufficient resources are devoted to the problem. Our mild flirtation with this research would become a committed love affair if petroleum prices skyrocket. But hydrogen isn't even my favorite energy alternative. Our country should explore the possibility of clean nuclear energy produced from helium-3.

UPDATE: Here's another energy idea.

Speaking of Energy Production

Well, I was...yesterday, but you kind of have to dig for it.

Those who insist that a hydrogen-based energy economy is impractical and undoable have a lot of recent news to contend with. It looks like we'll either find a way to do it at the molecular level or using good old atom-splitting technology.

I'm fine either way.

Energy Warfare

Ever since Steven Den Beste retired his word processor (actually it appears he's thrown it out the window, run over it with his car, and set it on fire), I've missed the sort of technical and knowledgeable blogging that engineers are often good at.

"Engineer Poet" is that kind of writer and so I'm glad to have him guest-blogging today at The Speculist.

Engineer Poet regularly blogs at Ergosphere.

-Stephen Gordon

Foreword:  This piece is late for its purpose.  I began writing it in late August and had a first draft in the space of a few days, then I set it down for a 3-week hiatus.  When I came back to it I had great difficulty getting to the next stage of refinement, and it barely changed through the end of September and the whole month of October.

Ideally this piece should have been done no later than mid-October.  Energy issues are crucially important to the USA, and anything which might have injected some reality-based discussion into the pre-election politics could not have done anything but good.  That opportunity is now gone, but I'm hoping it can still be of benefit.


We've 2 got a problem.  A BIG problem.  It's a problem as big as the biggest monster SUV, and as old as the Model T.  It's our dependence on oil.  Not only are the costs of oil depressing our economy 3 , the money we're paying is feeding a movement which is inimical to the United States and western civilization in general.  Even without that, we have still not fully dealt with the air pollution produced when the oil is consumed.

It's obvious to a great many people that we are already involved in a war.  Why not take the war beyond the spheres of military action and financial interdiction and attack the problem at its source, and (since You Cannot Do Just One Thing) a few others besides?

Specifying the problems and goals

Suppose that the US decided to take the following as national security issues:

  • Dependence on foreign (particularly middle-east) oil and vulnerability to price shocks.
  • Decreasing availability of N. American natural gas and price spikes.
  • Air pollution and its consequent health effects.
  • Increasing atmospheric CO2 concentrations.

The goals:  Reduce the need for oil and gas to moderate prices and cut the influence of their price on our economy, reduce pollution and cut atmospheric CO2 contributions.  (Whether or not the last is necessary or even desirable is the subject of much debate, but the scientists are the most reliable guides we have and they don't seem to have changed their recommendations yet.)

Further suppose that the US went on a war footing with regard to these issues, devoting about $100 billion per year initially.  What would it buy, and how fast could we see change?

Cold Fusion to Make a Comeback?

Cold Fusion, written off for more than a decade as junk science, is struggling to work its way back to respectability:

Later this month, the U.S. Department of Energy will receive a report from a panel of experts on the prospects for cold fusionthe supposed generation of thermonuclear energy using tabletop apparatus. It's an extraordinary reversal of fortune: more than a few heads turned earlier this year when James Decker, the deputy director of the DOE's Office of Science, announced that he was initiating the review of cold fusion science. Back in November 1989, it had been the department's own investigation that determined the evidence behind cold fusion was unconvincing. Clearly, something important has changed to grab the department's attention now.

Behind the scenes, scientists in many countries, but particularly in the United States, Japan, and Italy, have been working quietly for more than a decade to understand the science behind cold fusion. (Today they call it low-energy nuclear reactions, or sometimes chemically assisted nuclear reactions.) For them, the department's change of heart is simply a recognition of what they have said all alongwhatever cold fusion may be, it needs explaining by the proper process of science.

It's this sort of thing that makes predictions about future energy capacity and capabilities so difficult to predict. (For that matter, it's this sort of thing that makes the future in general so difficult to predict.) Cold Fusion may yet be a long way off, but the fact that it could be back on the table only goes to show the risks involved in assessing the future based on present capabilities.

We've seen a lot of discussion in the blogosphere recently about the viability of changing to a "hydrogen economy." The big problem with hydrogen is extracting it from water (or some other source, although water is probably the most likely.) A lot has been written about the impracticality of solar power, wind power, nuclear power, etc.

Personally, I'm quite partial to this model of using wind to extract hydrogen from water. It answers many of the objections which have been raised to wind.

But I haven't seen much written about cold fusion, either as a direct energy source or as a means of enabling hydrogen as an energy source. A while back, Steven Den Beste had this to say on fusion:

Wake me when it actually works.

Well, we won't nudge him just yet.
