How about dumping the batteries
How about if we put some major R&D into capacitors (so called super capacitors), charge up in less time than filling a tank with gas, would weight a tenth what batteries would making the car that much more efficient. Are we a looong ways away from where we need to be for them to work, we sure are, but you have to start somewhere. This would be the holy grail that electric cars need to get past everyone's range fears. How do we get there, pretty easy set a date when you can no longer buy a gas powered vehicle, I don't care when the date is, but set a date 10, 20, 30 years from today. We did it with digital TV, incandecent bulbs starting this year and so on.
