Batteries for electric cars are rechargeable - why can't a similar system be incorporated? Or does this fall into the "perpetual motion is impossible" theory?
Point 2 has been discussed on here before, and it does seem logical that a battery cannot contain enough energy to drive a car AND completely charge another similar sized battery.
