The best - and by "best" I mean "most depressing" - thing about ethanol-from-corn is that it's a net energy sink. It actually takes quite a bit more energy to grow and process the corn than it produces in ethanol. There's on way an ethanol industry would even exist without the colossal American subsidies to the corn industry. Not to mention the fact that the ethanol itself has a lower energy density than gasoline, so mixing it in with gas is simply diluting the energy of the gas.
