When I was a kid, I asked dad why can't one make a perpetual motion machines by powering an electric motor by the generator that the motor drives. Of course, I was too young to understand friction, heat, eddy currents, etc. Fast forward, it is amazing how many scam perpetual motion "free energy" motor generator sets are demonstrated on the internet.

For customers with a large amount of inductive loads, power factor correction may save some energy.
