It makes sense to further explore avenues of electricity infrastructure for transportation considering the steady rise and obvious applicability of solar power for vehicles. Bioelectricity could appropriately complement PV for electric vehicles. Once the cost of PV decreases and the grid is ready to handle additional renewables, consumers will hopefully demand electric vehicles more so than today.

100 mp/gallon? miles per kilowatt??-how do we refer to distance per unit of power?

Ethanol has enough problems to be a bad comparison. Why not instead compare methanol production with its byproduct of fertilizer versus burning, with no fertilizer. We need a replacement for oil-based fertilizers and I'd rather explore multiple options for transit than just cars.
