Startup Claims to Make $1/Gallon Ethanol

gnick writes to mention Wired is reporting that an Illinois startup is claiming they can make ethanol from most any organic material for around $1/gallon. Coskata, backed by General Motors and several other investors, uses a process that is bacteria based instead of some of the other available methods. The bacteria processes organic material that is fed into the reactor and secretes ethanol as a waste product.

    $1/gallon would be great if it were gasoline, but one gallon of ethanol doesn't store the same amount of energy as a gallon of gas.

    How many joules per dollar does that work out to compared to gas?

    Or, even better, how many miles per dollar does that work out to in today's ethanol-powered cars?

    That is a modest proposal if I may say so myself.

    we could get 2% efficiency, but if we're getting it cheap, that's all that matters, right?

    Yes.

    The efficiency argument as it pertains to ethanol is related to the so-called "energy positive" problem. The concern is that if it takes more energy to create the ethanol than it does to farm it and convert it to fuel, then what exactly is powering all that farm equipment? It can't be the ethanol, or we'd eventually run out of energy.

    On the other hand, grid power consolidates the power infrastructure and therefore is wonderfully inexpensive. If this machine did nothing more than take grid power and convert it straight into ethanol, it would be a miracle machine. It's almost as good as if you had a machine that converted uranium or plutonium directly into millions of barrels of ethanol. If you get a slight boost from the energy already stored in the corn, so much the better!

    The key thing (economically) is to get off of oil. Oil is starting to weigh down our economy and gives far too much power to current and potential enemies. Making transportation cheap again would rebound the economy, bring food prices back in line, and generally improve things for the U.S. (and really, the rest of the world) all around. :-)

    "inthishouseweobeythelawsofthermodynamics" is cute when someone's bragging about their perpetual motion machine. It makes you look ignorant when the story is about someone converting one form of energy to another in an incrementally more efficient way than before. News flash: it's obvious that current production methods can be improved upon. What part of that smacks of breaking the laws of physics?

  6. No way will it cost $1 per gallon by GreatDrok · · Score: 4, Insightful

    Don't expect the price of any petrol replacement to be any less than petrol if widely deployed.

    One of the reasons for the high taxes in the UK for fuel is that they want to keep traffic numbers down. Pushing the price up should discourage people from driving so much in theory. Of course, the government just becomes dependent on the taxes and so will want a big cut of any other fuel source. Certainly, in the UK if you drive a diesel fueled by used cooking oil, a waste product which would normally be dumped, the government expect you to pay tax on it. The justification is that the tax is used to maintain the roads although that is supposed to be what the road tax is for. Anyway, it is currently cheaper to use vegetable oil and pay the tax than to use fossil diesel but if it gets more popular to use such biofuels the price differential will go away. Sure, they will be largely carbon neutral but the government will still want the same amount of income from fuel sales, they're addicted. I think the US drivers will have to get used to similar things. Accept it, whether the fuel is from fossil or modern sources, the price is going to remain high. You'll never see $1 per gallon again.

    The nice thing about ethanol is that continued research is almost guaranteed to drive down the price-per-energy cost by orders of magnitudes

    That's true of most technologies. e.g. If we were to embrace hydrogen, I can guarantee that the price of hydrogen fuels would drop like a rock over time.

    The real beauty of ethanol is that it is similar enough to gasoline to make it a viable alternative for powering existing engine designs. Which means that the massive investments made in the modern, overdesigned, otto-cycle piston engine can continue to be leveraged while new engine technologies are developed.

    In short: Hydrogen would require an entirely new infrastructure. Ethanol would not. Which is a huge win for ethanol.

    Just so you know, as soon as I read the first five words or so of your rant and saw the ad hominem attacks coming, I stopped reading. If you want to make a point, try to do it without resorting to insults. Obviously you cared enough about what you wrote to wrote a large diatribe, and if you want your time to be used effectively, you shouldn't hurl insults, because it just means you will have wasted your time in writing it.
