Sadly there all kinds of free energy videos on Youtube.
Shoprt answer here is both motor and generator have losses,
electrical and mechanical, and of course extracting energy from
the combo adds to that loss. Losses then cause the energy
production to fall, and that sequence, classic differential
equation behavior, falls ultimately to ZERO.
So nope, this doe not work.
Even the generator betwxt said ultimately slows the earths rotation rate to ZERO,
again the energy production evaporates.
And of course we have the second law of Thermodynamics that tells us all
irreversible systems essentially "disintegrate", my term.
Lastly if we could find a way of converting dark matter into energy, since it
appears to make of most of the universe, we could get what looks like free
energy, maybe even restart the universe due to elimination of most kinetic
energy and subsequent gravitational collapse to retrigger another big bang,
the time span would make it look like boundless free energy....speaking as
a non physicist, read makes my intellectual entropy maxed out, hence
worthless.
