If we put the ecological aspect aside, because it's controversial to say the least, I always wonder how one expects to have a battery serve as a propulsion source, while the same battery technology can't even provide enough juice for a modern mobile phone to last more than a day or two at best. I know vehicle Li-Ion batteries have much more sophisticated management and are much bigger (and heavier as you point out), but still they can't really "run away from their roots/handicaps", can they?
