This is interesting
, and would be more interesting if there were a measure of how much diverting corn into ethanol (25% of the corn crop in 2007 produced 2.65% of the US total demand for gasoline in 2006) had an effect on prices of food. Northey is right. Corn ethanol has to be a transitory technology. But the US will need to find ways to get ethanol from the field to the pump. Where is the infrastructure going to come from, who's going to build the pipelines. And at the end of the day how much real difference will it make if there is no corresponding increase in fuel efficiency?
