If you have a double shaft electric motor with one end turning the wheels of a car and the other turning a generator to charge the batteries, would that not take care of the range and recharging problem? I mean it is necessary to maintain the charge from an alternator on a gas engined car to maintain the battery for using headlamps, wipers, air conditioning, etc, etc. If the battery dies the car will die because the computer and ignition system must have power to operate. Maybe I am not understanding something that everybody else already knows. I am willing to hear any ideas.

Thanks, T.W.
