dunno. interesting questions. if it takes 1,000 btu to evaporate a pound
of alcohol and we get 10,000 by burning it, we might be ahead of the game
with a good heat exchanger and enough insulation, especially if we ferment
indoors, and count the heat of fermentation.

that may well be true, with conventional agriculture.

could be the moisture content is too high. then again, we have corn stoves, 
and drinking alcohol could be an interesting byproduct.
