 If it were just up to the markets in the United States and there were no politics being played, I would guess that ethanol would be somewhere between 20 and 30 percent of the U.S. fuel market. And we'd also be optimizing engines to run on it. Ethanol is such a superior fuel to gasoline. When you build cars for it, it doesn't have a competition. But ethanol is a very, very efficient, powerful fuel. We should be using more of it.
