In Brazil, 20% of what goes into gastanks of cars is bio-ethanol. Today.
Already. And, just about market priced with gas. No fantasy. All reality.


I'm not convinced this stuff is the way to go. It's more expensive than
regular gasoline, and you get fewer MPG. The guys who are basically
converting garbage to ethanol may have a market (and I applaud their
efforts), but the idea of growing corn to make ethanol is a dumb one.


Not necessarily. Have a look at this link has to say:-

That link doesn't say anything about the overall thermodynamics of the
process and how it compares to refining oil.


it says something about the financial viability of producing ethanol to
meet our enegrgy requirements. It isn't a failed concept as you claim
it to be. Solar and wind energy are highly capital intensive. In
contrast, ethanol is a lot more financially viable. BTW-I might have
replied by mistake to one of your posts on this thread.

I have a PhD in chemical engineering and my area of expertise is thermodynamics. Your expertise is in what? Look at the overall energy balance (this is something I could make undergraduates do in their thermo class) and what does it tell you?
