Corn ethanol will not work without massive government subsidies from seed to gas pump. Without these subsidies ethanol blended fuels will be even more expensive than regular gasoline and the market will quickly abandon ethanol fuels.

Corn ethanol subsidies totaled $7.0 billion in 2006 for 4.9 billion gallons of ethanol.

That's $1.45 per gallon of ethanol (and $2.21 per gal of gas replaced).
