Sony Getting Closer to TVs With No Cables Whatsoever [Wireless Power]
Sony'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.
Sony says that this system offers 80% efficiency, which may get reduced to about a minimum of 60% if there is a misalignment in the frequencies, which needs to be corrected.
I don't know if this is safe for our bodies or not, but I would like to have it. Even if that requires me not wearing my tinfoil hat while watching the sixth season of Lost. [Sony via i4u]
