Sony Prototype Sends Electricity Through the Air

Posted by ScuttleMonkey on from the efficiency-is-overrated dept.

itwbennett writes "Sony announced Friday that it has developed a prototype power system based on magnetic resonance that can send 'a conventional 100 volt electricity supply over a distance of 50 centimeters to power a 22-inch LCD television.' Unfortunately, Sony's prototype wasted 1/5 of the power fed into it and additional losses 'occurred in circuitry connected to the secondary coil so the original 80 watts of power was cut by roughly a quarter to 60 watts once it had made its way through the system.'"

    But if they can't improve on 50cm, I'm just getting a 2ft extension cord for fixed items.

    (sorry for mixing units)

      I don't know, if they could make it out to 1000 barleycorns or even several rods, i'd buy a hogshead of them next fortnight.

    If this is a Sony technology, you better believe the electricity is going to be in some kind of proprietary format that requires you to purchase special electrons at a 30% premium over industry standard.

    I here someone once figured out a way to send signals from a TV station to a TV set without wires. Crazy I know, but true.

    Only another 42,163.9995 km to go to use this to send solar power from geosynchronous orbit.
