Ain't No Way that this can be true, and bet that he has NOT build a unit to do it yet nor will he ever.
Good example is a picture tube.
A car alternator may have magnets in it and as powerful as they can be, it takes increasing energy to turn the alternator as the load nears a short circuit or low impedance load. The turning of the shaft IS reflected in the load, because a magnetic field by itself can not produce energy until we add kinetic energy to move the magnets past conductors thus inducing a time varying current. Sure the electrical path is isolated from the time varying magnetic field, but if it where not for that time varying and highly magnetic field there would be no induced current. It's time that new technology is brought to the masses. That is the claim.
