I kinda wondering how the claim can be made that ethanol produces more energy than gasoline? From what I remember in organic chemstry there's about 25% more Kcalories in gasoline than ethanol based on the same volume. This makes ethanol only about 75% of the power of gasoline.

Now, for efficient electrical transmission you need room temperature superconductors that haven't been invented yet.

Far as I know the most efficient hydrocarbon is still diesel, which is easier to refine than is gasoline.
