Just a small observation... I know there has been much talk in this thread about how ethanol contains less energy than gasoline on a pound for pound basis. Ths is absolutely true. However, I think the point is moot, as we are talking about engines that are not 100% efficient. The energy basis is known, and a 100% efficient gasolie engine will yield more power than a 100% efficient ethanol engine given the same amount of fuel.
But when the efficientcy of the engine is a variable, the fact that ethanol contains fewer BTUs than gasoline becomes irrelevant.
It is my opinion that this fact does not support nor deny any argument provided here, it just may help us avoid a red herring.
