Intel wireless power is pure magic, most efficient yet
The final frontier of wireless tech is upon us, with Intel showing off its electricity flying through the air with better efficiency than ever. While it’s not the first wireless power transmitting device we’ve seen, this one uses resonance rather than induction, and boasts 75% efficiency. Hey, that means if you send 100 watts across the room, 75 of those watts will actually make it to the other side.
For now, the prototype is in the form of two copper rings that resonate together at a certain frequency, magically transmitting electricity from one to the other. Of course the tinfoil hat-wearing cranks will want to know where that extra 25% of the obviously deadly radiation goes on its way from here to there, but Intel says never mind that; it’s safe for us, it’s just that the gadgets will get fried with the current tech.
As soon as this is perfected, we’ll be in for a techno treat. Imagine wirelessly charging up your cell phone, or quickly installing some truly wireless speakers, or placing a wireless toaster on your kitchen table. The possibilities are endless. But in this era of energy price hikes, do we really want to throw away 25% of the power just for the sake of convenience?

Another invention that is stolen, I beleive Tesla's Design was not as small but same principle. Give the credit where it is due.

Well, internet access is heading towards being as ubiquitous as cellphone signal, it would be nice if wireless power gets to that point someday...Plugs and wires are so 20th century...

Imagine folks trying to steal electricity instead of wireless Internet. Maybe when power is abundant we wouldn't care, but do you see that happening anytime soon?

I'm sure it's completely harmless, with nothing at all to worry about! http://notnews.today.com/2008/08/23/intel-demonstrates-wireless-power-for-the-home/

What happened to the stars for ratings?

Intel has NOT created anything NEW !!!!!!
Tesla proved this....even you can do it....make a flat coil, attach it to a light bulb and walk near high power lines....it will light....
You know what they say about living under high power lines.....
Well it is true. Powerful electromagnetic fields, used in intel's inductor HARM THE DNA. They are dangerous. They are playing idea that the FDA is backwards and doesnt know this nor does it test such reactions....
I hope this NEVER goes to market....for the sake of our health....
This is as dangerous as radioactive medicine....and look...it wasn't magic...it didnt cure anything...people died...

That might sound stupid... but what will happen to me if I will be hit by transmitting energy? Nothing?

If I send 100W to the other side of the room with powercables, 99.5W makes it, isn't that amazing? 75% is just not efficient enough in a time we should be conserving energy. And what about the generator, humming away al day, using power even when it's not used like a cellphone charger?
BTW is this the same induction thing that gets a tubelight going when standing under a high voltage powerline?

@shdwsclan
You are exposed to a larger EMField working in an office building then living near power lines (of any type)
There is no corrilation to health issues and EMF simply because the data is not complete or the people that are sick would have got sick anyway wether they lived near power lines or otherwise statistically speaking.

If we stop and consider that EVERYONE who drives an automobile is only using less than 20% of the fuel energy to move the car (the rest is mostly lost heat - that's why it has a radiator!), using pure electricty at 75% efficiency is a blessing!! Even photovoltaic cells (as in solar panels) can't rreach over 30%, and that is using free energy from the Sun. So if I can put a large coil on a small car and have the government place larger coils under the highways, even charging us for the energy the car uses, we will spend much less energy, pay less, and waste only 25% in losses which is better than with existing gasoline, biofuel, solar, or hydrogen means of transportation.
And with even more energy, we can have magnetic levitation and use no tires or mechaical brakes. The future is coming as we expected it. I like the idea!!

@shdwsclan, @poli --- you obviously didn't even read the article. Intel's tech uses RESONANCE not INDUCTION. It's NOT the same thing. Good grief people, READ before you kvetch please!
By kolshire at 11:19 AM ON 08/28/08
and the "accreditationists" fail, because nowhere in this article are the words "invented by" or "intel's invention" even used.
in point of fact, examine the second sentence:
"While it’s not the first wireless power transmitting device..."
By skylarkbw at 2:09 PM ON 08/28/08
100 year old crystal radio technology.......also uses tuned resonance and rectifies some of the signal to operate the receiver.
Looks like an air core transformer (I know.....inductance) or an old fashioned spark gap transmitter and receiver.
By Ayilachan at 2:25 PM ON 08/28/08
everyone's complaining about the 25% loss of energy.. but If I remember correctly, aren't we only getting like 35% efficiency out of existing powerlines? sooo... this is actually BETTER than what we've got now.

This is nice that more companies are getting involved in the wireless electricity revolution.
I know that a company called PowerBeam is also involved in the wireless era and they safely transmit energy through optical energy, instead of the copper wires and the electro-magnetic field.
By using optical energy they can send energy over long-range distances. Their device also has a safety system so that it shuts down if anything is close to the beam.
I'm not exactly sure how efficient their system is but if you're interested in more info check out www.powerbeaminc.com
