The mechanical energy of the second motor is converted back into electricity. But nothing is 100% efficient and there is an energy "loss" (actually heat generation) at each stage (conversion or transfer), so the final electrical energy is not sufficient to run the first motor at the same speed, so in a few seconds all levels of energy decrease to zero in a reaction loop. | |
