Sony Getting Closer to TVs With No Cables WhatsoeverJesus Diaz10/02/09 1:28pmFiled to: wireless powerWireless power transferSonyEnergy91EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkThis TV has absolutely no cables connected to it. No video cable. No audio cable. And no power cable. How's this wicked sorcery possible? Thanks to Sony's new Wireless Power Transfer technology, which can send 60 watts over the air.AdvertisementSony's Wireless Power Transfer can push 60 watts of electrical energy over almost 20 inches (50 centimeters). That's a pretty decent distance, especially when they say that it can be extended using passive extender units. In fact, they have already achieved 31 inches in other tests.They claim that their method—which sounds similar to Intel's—uses some dharmastastic magnetic resonance, in which electromagnetic energy gets transmitted from one device to another, both sharing the same resonant frequencies.
