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?

    Dewey, what part of this looks like authorities should be involved?

    Corn on the other hand $502 per acre to produce.
    How much without subsidies?
