The world and its doggie knows about induction - heck electric tootbrush chargers are based on the paradigm.
But today Intel claimed it has proved Nikola Tesla's theories and that will happen very soon.
Intel has managed ro realise Teslas's dream of transmitting electricity - an idea considered somewhat stupid at the time Tesla had the bright idea, and also invented alternating current, even though America was definitely DC.
So far there is only 50 percent degratation in wattage, according to Intel labs.
Intel has already realised Tesla's dream of transmitting electricity across the wires for 30 metres.
It is a work in progress but it already works.
