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.

What! GM backing cheap fuel!

Whatever happened to the conspiracy theorists from my childhood, you know, the ones who always claimed "the car makers and big old buried that 100 mpg carburetor design", and the like!

I don't know the merits of this particular deal, but it never made sense to me that "car makers" really cared one way or the other about the fuel costs (and the SUV craze has borne that out...)

Did you consider the cost to plant, harvest and produce potatoes and beets, etc vs corn?

Potatoes cost $2017 per acre to produce.

Corn on the other hand $502 per acre to produce.

That is a rather large difference, corn production also requires next to no man power where
as the production of potatoes (root bound crops) is considerably higher.

Correct. Unfortunately, the current refinement processes still result in a more costly product per unit of energy than petroleum. Gasoline prices are close to making ethanol affordable, but not quite. The advantage to this process is that it would make ethanol cheaply. A result that is far more desirable than pure efficiency. If it's highly efficient in the end, all the better. :-)

BTW, Pimentel still disagrees that ethanol is energy positive. He's really just being a jerk, pushing data that's nearly 30 years old. Not a single study that's independent of his numbers has shown the same results. The only problem is that there are enough gullible people who listen to him. :-/
