Here’s a very good idea. There’s an article on Forbes. We need to skip the whole painful hydrogen and ethanol and biofuel psudoadvancement and go right to electric cars. Solar peaks in the day, wind peaks in the night. Balance out the load by allowing utilities to borrow power back from the cars, provided the driver has not disabled this ability. (Like they’re leaving soon or something?) Really, why are we even trying to set up another flawed model of distrubution of liquids for powering vechicles? Electricity really is the renewable way to go. Besides, I remember reading somewhere that two thirds of oil in the US is used for millitary use and transporation trucks and the like. Although changes in consumer technology could definitely help, the millitary and transporation and freighting industry will need to get involved too. The article is here.
