corn ethanol has been around for decades, and it hasn't gotten anywhere because of the low yield per acre. The current excitement is about cellulosic ethanol, which is fermented from any cellulose (grass, wood, debris) using specialized enzymes.
The National Renewable Energy Lab has gotten the cost of cellulosic ethanol down to about $1.15/gallon.
15% gasoline is added because the flash point of pure ethanol is too high to start a cold engine.
We drive these clunkers at work that run on E85, and they sometimes stall when cold. Otherwise they drive like a normal car.

A democracy cannot exist as a permanent form of government. It can only exist until the voters discover that they can vote themselves largesse from the public treasury. From that moment on, the majority always votes for the candidates promising the most benefits from the public treasury with the result that a democracy always collapses over loose fiscal policy, always followed by a dictatorship. The average age of the world's greatest civilizations has been 200 years.
