Well, it's an interesting question. As a side-issue I have to say that I have never quite understood why the energy content per Gallon of Ethanol is such a big deal. A so-called "Downside". So you have to build a slightly bigger fuel tank. Big deal.
It's only about 27%-29% less, or so, in energy content per gallon. That is annoying, and, as I said, I agree that you have a good question going, if only for intellectual interest, but I don't see so much of a downside to this aspect of ethanol. Maybe others do. It has nothing basically to do with mileage, in my view, which is what I think some (but not all) people are getting at when they criticize the lower energy density of ethanol. A good way to measure mileage, in my view, is miles-per-unit-energy, not "miles per gallon" since different fuels have different energy densities per unit volume (and different masses per unit volume, for that matter). Sure, it's true that if ethanol is generally apportioned into cars in gallons, and if costs are compared, this makes it even harder to argue for ethanol (in over-simplified arguments) but I think the basic economic argument, if such a simple argument is to be part of the discussion, should focus on $/mile, not $/gallon. Each fuel has its own way of doing things. You probably didn't mean for me to get into much of this, so as I said, just using it as a foil for a side issue.
