Thirsty autos. The more I write about biofuels the more I am convinced that there is an elephant in the room that no one is acknowledging. The elephant is automotive fuel economy.
There is no point using expensive grain to make a gasoline extender if its just going to poured into inefficient autos and burnt. Robert Rapier said at the end of last year fuel ethanol is boondoggle.
That doesn't apply to all biofuels, but when you look at the potential gains in green house gas reduction, compared to the savings that could be made by making cars a little more efficient, you have to wonder where people's priorities are.
