It would literally change anything. I've read somewhere that only in the US they could shutdown 3 nuclear powerplants simply by "saving" the energy that is usually lost when transmitting through wire. Sensors like Hall-Sensord (which are actually used in some keyboards) would be wayoe precise (which wouldnt make any keyboard greater but yeah, you get the point). Think of the dynamo used on your bicycle to power the lights - even more effective. And although I am not really convinced of this one, you would be able to store power in a loop of wire, effectively making batteries which save the energy from the electric net when there is just too much power being produced unnecessary as you can just leave it cycling in the loop without it slowly fading away.
