Sony’s Wireless Power Transfer can push 60 watts of electrical energy over almost 20 inches (50 centimetres). 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]

Why the surprise now? this is old technology being widely introduced to the public for the 1st time. You wouldn’t see this in the late 19th century – due to the government’s controlling/possessive nature, so why now? why is wireless power transmission finally being introduced without a sound? Is the government slowly letting it out to blend in with half the other new technology? rather than suddenly in the 1890′s?
Intel’s (and sony’s) wireless technology uses the exactly same concept that nikola tesla used for the basis of wireless electricity – Magnetic Resonance.

You will be surprised about how similar this technology is with his tech.

Monday, October 5, 2009 at 10:08 AMObviously there were some hurdles to overcome, seeing as sony is struggling to transmit over 60cm, I don’t think it was just the “we don’t want wireless electricity, cause then we can’t charge ppl for it” reason.
I don’t care so much that it was possible centuries ago, I’ll care when its in my home actually being used, something Sony is Obviously working towards.
However, when it comes to things I want wireless, my TV that sits forever in the same place is not the first appliance on my list…

Thursday, October 8, 2009 at 12:15 AMhaha wanna make a bet? Why would they release something that would in turn be distributing free electricity!? They used “lack of funding” as an excuse. Seriously.
It was his other projects that had them worried a bit – like his death ray/particle beam projector concepts, but this was just the easiest way to silence him a bit.
“I’ll care when its in my home actually being used, something Sony is Obviously working towards.” That’s pretty simple thinking. Do you know how much they are going to charge for this kind of technology? Prices and demand are going to be incredible. They’ll probably intergrate it into the newest line of TV’s starting at around 10k.
Besides, Sony is working towards a Wi-Fi version of his work. He was attempting to create something 3G sized.
They’ll probably just make simple wall sender/receiver units that’ll transmit and receive power at the wall socket. Tesla actually tried making wireless power towers that looked like radio stations that actually distributed wireless power to an entire city, rather than a home.

Monday, October 5, 2009 at 4:33 PMThe problem with Telsa’s earlier work was that it kept producing clones of cats, Top Hats and Hugh Jackman. Hopefully they have sorted that out.
