You might want to Google on this professor Pimental that so many of you folks think hung the moon. His problem with ethanol is that it's largely derived from corn and he hates corn because it's used as an animal feed. He's a raging vegan. (and his claims as to energy innefficiency have been thoroughly repudiated by virtually every other researcher to look into the matter)
"(and his claims as to energy innefficiency have been thoroughly repudiated by virtually every other researcher to look into the matter)"
Uh huh.
And who paid those researchers that refuted his claims?
