(snip) My wife and I visited the Reeves AgriEnergy Company in Garden City KS a few weeks back. The spokesman said at the time it took 36,000 purchased BTU's to make a gallon of anhydrous alcohol and that a gallon of anhydrous alcohol (I can't remember) somewhere around 70,000 BTU's in it. He also said they sold anhydrous alcohol for .97 cents (US) a gallon. This does not include any road or sales tax.
