E85 will make perfect sense once petroleum is removed from the distilling process. Ethanol will be one of many methods to "store" solar energy. It's still going to continue to be important in the internal combustion field. Current marketplace E85 doesn't make much sense, but it is a stepping stone. It's not a dead end technology, it's just one that requires a good amount of energy to to expended on its manufacture. Eventually, the price of this energy will decrease.
