This would be wasteful. Generators are used in electric car braking systems (the motor is turned into a generator) so that the forward motion recharges batteries, as the load from the generator helps stop the car.
thank you very much for your knowledgeable,and clear answer,i once hooked up a dewalt drill motor,to a altenator,and produced more energy than consumed, perpetual ? is 13.5 enough to recharge 12, yes !
a form of it is called regenerative braking and is used on many hybrids. But there ain't no free lunch. It stops the car like regular brakes and feeds power back into the battery.
No. Perpetual motion machines don't work because of inherent loss.
