Intel Demos Wireless Power

[DSM4Life]

Intel (NSDQ: INTC) on Thursday showed off its technology for transmitting power wirelessly, a capability that could one day help eliminate the wire clutter behind desks and other areas of the home or office.

Wireless power was one of several technologies Justin Rattner, CTO for Intel, highlighted at the last keynote of the chipmaker's Developer Forum in San Francisco. Rattner also rolled out Intel's work in robotics and "programmable matter," which is the ability to manipulate the shape, size, and even color of an object.

Alanson Sample, a University of Washington intern at Intel's research facility in Seattle, demonstrated the ability to transmit 60 watts of power a distance of two or three feet, using two round metal coils, one as a transmitter, the other a receiver. The latter had a light bulb on the top that remained lit as Sample, a graduate student in electrical engineering, moved the coil around.

The technology builds on the work of Marin Soljacic, a physicist at MIT. Intel and MIT researchers are leveraging a phenomenon know as "resonant induction" in transmitting power.

Intel's system, called a "wireless resonant energy link," relies on strongly coupled resonators, which operate on a principle similar to how a singer can shatter glass with her voice. The receiving resonator absorbs power at its natural frequency much like a glass absorbs sound energy at its natural frequency.

If the technology finds its way into our daily lives, it could one day make it possible to recharge or operate a laptop or any other device simply by placing it on a desk or table with a wireless power device built in. If these devices proliferate, then we may no longer need a notebook battery, for example, a capacitor could be used instead to store power temporarily, Rattner said.

No timetable was given for when the technology could find its way to the market. Intel is working on miniaturizing the power-receiving antenna to a size where it could fit in the base of a notebook.

That is pretty sick

I wonder how they will minimize the whole 'sick building' phenomena though.

Its cool and scary at the same time. What i find interesting is tests show they only lose 25% of the energy when pushing it through the air. If energy can't be destroyed then where did it go ?

I should extrapolate.
In the states, apparently you guys define 'sick building syndrome' as being related to poor ventilation..

In the caribbean it refers to feeling lethargic in response to electromagnetic fields generated by having shitloads of electrical equipment in your office. Well, lethargy among other things.

I wonder how they'll negate that.

Absorbed/Conducted by surrounding organisms and materials?

Absorbed into humans

[spywizard]

or power cars.. lines in the ground/roadway.. power pulled from them..

easy..

[Narkissos]

Absorbed into humans

That'd be bad-ass if it gave me super-powers.

Nikolai Tesla was doing it in 1898!

(Yes, I'm a huge Tesla fan! Edison was a cheap hack and stole other peoples ideas!)

Thats easy , em fields of the low strenght that is emitted from electrical equipment have no effect on humans. In sweden we have a phenomenon called electricity allergy where alot of people are convinced they can not be close to electrical equipment or power lines. Of course its all in their head though because ever study ever done has shown its bunk. There are alot of bs about microwaves from cell phones aswell circluating here aswell.

that's pretty cool but it took them long enough!

Tesla worked with air coil transformers ages ago. A transformer is just 2 coils near each other that transmit power....they are not connected and work on inductance. Only problem is getting them to work further apart which i guess they have finally done.

my sonicare toothbrush does this but again, in close proximity. You just set it on the stand and it charges. There are no charge tabs or leads or anything.

I've read the studies.

I also know what i've experienced.

To me that'll be one of those things that we'll be back and forth about for another decade or two until science sits up and shouts "Eureka".

Just like the 'steroids don't work' assertion.

Not doubting your experience. But in a office environment there are just to many other plausible factors at play to be able to single out em fields. Lighting(especialy if its fluorescent ones), air quality etc. When it comes to EM fields there is just no know credible way they can have a impact on the body.

It would be interesting though to walk around with a gauss meter at places where people feel lethargy and compare it with the em field in their living room or computer room. Or just put 100 or so random people in a room and crank up a nice em field in it without them knowing it to se if there is a response. I remember(but cant find reference ) that some kind of study like that has been done in sweden where it was shown that those with electricity allergy can not feel the effects of electrical equipment if they dont know its around.

It isnt destroyed it merely changes forms. It is more than likely lost as heat or charging particles in the air or both.

I wish I would have thought of this invention, I could have made a million dollars. You know the guy that invented the pet rock made a million dollars.
