In about 1956 (shows how old I am !) I had a toy car made by "Distler" - think that is right spelling. It was German and powered by a small battery thingy which my Dad called an 'accumulator'. You charged it up with a specific charger shaped like a petrol pump. It didn't run for all that long but was pretty cool for the time. Now , things have moved on a bit since then but we,apparently, still can't produce a viable battery to power a car. Would it be cynical to suggest that there are vested interests at work in not progressing such development.
NB watch 'The Stone Cutters' episode of The Simpsons for a hint.
