I've had some pretty crazy ideas lately, not sure why. But, my latest idea is to create an electric car that charges itself.

On a normal car that uses a combustion engine, the electrical system is charged by the alternator which is hooked up via pully/belt system to the crankshaft, and it turns (creates an electric current) when the engine is running.

So, on a 100% electric car, why couldn't you hook up a series of alternators to the non-drive axle. So, when the car is in motion, the axle is turning which in-turn turns the alternators and creates a charge to keep the batteries charged up??

Make any sense? Why wouldn't it work?
