ethanol is fine.
Well, the only reason corn would be a biofeedstock and is used in the US is because there have traditionally been surpluses. But it makes a lousy feedstock for many reasons, not the least is that the hybrid stuff they now grow is so dependent on chemicals that it IS too expensive to turn into corn.
There are MANY better ways to make ethanol, including enzymatic hydrolysis of cellulosic waste....wood, waste paper, cardboard, green waste, yard clippings, old cotton waste and CORNSTALKS and COBS. The economics of this are more complicated, but you have to calculate the advantage you get from slowing the fill rate of landfills. Sugar cane and switchgrass have much better yields, in fact, our cane industry is getting a boost here with the construction of an ethanol plant on Kauai....it has been delayed for a year or so, but should come on line in 09.
Forget that stuff about corn, I'm sure there will be some made out of it, particularly in the midwest, but most ethanol will be made for local use....very cool aspect of the economics of ethanol.
I look forward to the day when we can get the gasoline out of our ethanol. Anhydrous ethanol has an octane rating (R + M /2) of 116. I can run my TT special on it.....after I put it together!!! Makes a bunch of power, produces very little carbon deposit, and cools the internals better than gasoline. If you spill it, you can lick it up, with a slice of lime. It's the fuel Henry Ford envisioned that his cars would use.
