I, too, think ethanol is a remarkable fuel for racing.  It burns cool, 
it allows very high compression ratios, and it produces very high 
specific outputs for a given capacity engine.

BUT, it contains about one fourth as many calories as gasoline, pound 
for pound. This means that to reach a certain power output, the engine 
needs four times as much ethanol.  One author I read stated that there 
just isn't enough arable land in the world to support our energy habit 
on an ethanol economy and still allow us to eat.
