Hear me on this: IF MY WHEELS ARE TURNING, WHY ARENT THEY SPINNING SOMETHING THAT IS RECHARGING THE BATTERIES.? How hard is this? Say the car has four motors, one at each wheel. Forget a big battery, the hull of the vehicle, like a Tesla, would have a massive generator rather than a battery. You don’t even need a battery to drive a car. You need a battery to start a car. In my scenario, you would still only need a smaller battery to get the car rolling, then the generators would take over and power the car. The battery would be bigger than a die hard form sears, but it would still just start the car,.
