As should the "self charging electric car".

Jim: Those are the exact results we keep telling you that you'd get. There is no magic in electricity, the energy has to come from somewhere. If you use a battery to run a motor, and DIRECTLY use that very motor to ONLY run a generator to charge a second battery - and then keep switching the batteries - in time BOTH BATTERIES WILL BE DEPLETED.

Subtract from the equation the energy required to move a car, and the batteries will be discharged even faster - the energy to move the car has to come from somewhere.

Your gas engine would provide about 4,000 watts of energy. BUT IT IS STILL ONLY 5 horsepower. It does not magically become more because it's converted into electricity - it actually becomes LESS dues to the losses and inefficiencies mentioned.

AGAIN...
The energy required to charge a battery is GREATER than the energy you can get back out of it.
ALSO, the motor and generator both have losses - all of these inefficiencies add up to mean that "self charging" simply is not possible.

Is physics really this hard to understand?
