Batteries are not the way of the future. Sorry. Battery cars are currently failing hugely even with government aid. Tesla(Electric Lotus Elise, Government funded) just went under and is no more. The problem with electricity unless tapped from the Air as Tesla intended, there isn't enough to revolutionize the motorized world. Where does electricity come from? Coal, Natural Gas, Damaging Dams, Nuclear Power Plants(Despite human error it could be the greenest form of energy possible , even without the use of Helium 3 AKA Cold Fusion), etc., all of which produce more electricity than turbines or Solar panels could ever hope of equaling. Everyone wants clean energy, problem is that it doesn't exist. Going green is BS.
Also, Battery power = HEAVY... Especially if you want more than 30 minutes of ride time...
