Sep 20, 2006 — Ethanol fuel is grain alcohol blended with regular gasoline. E10 is the most common blend, 10% ethanol, 90% gas. It runs in regular cars. About a third of the gas sold in America is E10. E85 is 85% ethanol and only runs in specially designed engines. Ethanol is big business for American corn farmers. But corn isn't the only crop you can make ethanol from. And it may not be the best, for the environment or for North Country farmers. New York State is taking steps towards a radically different kind of ethanol production. Gregory Warner reports.
