Sony Prototype Sends Electricity Through the Air 240

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.'"
