Wireless Electricity = WiTricity
Resonance causes an object to vibrate when energy at a certain frequency is applied. This is similar to the premise behind the old shattering wine glass gag. If a glass resonates at the same frequency as the singers voice, it will vibrate and shatter once enough pressure has built up. In the case of WiTricity, a charging device sends out low-frequency electromagnetic waves to a gadget. If those waves and the gadget to be powered resonate at the same frequency, presto, you've got wireless electricity. Of course, it's not that simple, but that's the gist anyway.
This technology has the potential to power a roomful of gadgets and appliances with just wireless charging device. It can even work through obstacles, including walls. The next step for the group is to shrink the technology down since the current copper coils used for demonstrations are two feet wide.
And before the paranoid technophobes out there start beating their drum again, let it be known that there is no danger to humans from this technology. The field is almost entirely magnetic and the human body doesn't respond to magnetic fields.

It's my understanding that the human body does react to a magnetic field. Isn't Magnetic Resonance Imaging (MRI) technology based on the cells reorientating themselves in this kind of environment?

I would call it Wi Tri (Y TRY)

What about people with devices such as pace makers and vegus nerve stimulaters. They can't be near other devices like microwaves or MRIs so wouldn't they be at risk?

Think of using it to power pilotless vehicles on a new electrified freeway grid, vehicles could get their power directly from the road.
This could be our future, visualize it and screw the Arabs !

Nichola Tesla invented this in the 1910 era. He was a genius. Let's give credit where it is due. Don't show a bunch of nerds in the picture with the story like they came up with this idea out of the clear blue. Ask them, I'm sure they've read his theories and applications of wireless electricity.
Mike @ Jun 9th 2007 8:53PM
Come on guys, give credit where credit is do! No matter how you disguise your work with fabricated theories, it is still the same experiments that Nikola Tesla and others have previously explored. Without wires, Tesla lighted a bank of 200 light bulbs that were 50 watts each from over 26 miles away during his Colorado Springs experiments in 1899! Beat that, all you nerds!

Telsa's experiments involved electrostatic fields, not magnetic, and did not power the light-bulbs through the air, but by passing the electrostatic forces through a natural conductor, namely the Earth. It was wireless, because there were no wires, but it was not contact-less.

Thank you to all who remember tesla's work. I almost fell off my chair when I read about this.Tesla was THE master of frequency vibration. This is 100 year old technology reborn thru forgetfulness. Lets use it now.

Tesla was asked by J.P.MORGAN ,his financial backer ,where does the meter go ,when tesla came up with his idea to get free energy from the air,using antennas pointed up into the atmosphere
J.P.MORGAN Prompty dropped his funding !
If,anyone here doubts the exsistence of getting energy from the air,ether,basic substance,etc...
then you may be interested in the subjects referenced in the website listed below

This would effect people the same way power lines would.
Terrence O\\\'Brien @ Jun 11th 2007 10:43PM
@Brian
Please don't toss around insults with out doing your research. Because of the extremely low frequency used to transmit power a person would be with in one wavelength of the power source. Within the first wavelength the radiation from the field is almost entirely magnetic.
Please follow the source link to the BBC article.

"They" will never let anyone develop anything they can't charge you for. There are all kinds of ways to get "free" electricity, and even far less expensive ways to run your cars. They can make them-----they won't. (No name, please)
Ken Wielfaert @ Jun 12th 2007 1:23PM
What about all the medical gadget implants controlled or adjusted by magnetic waves such as brain shunts, etc.?
Brian @ Jun 12th 2007 11:34PM
This device won't create energy so that comment about messing with the Arabs doesn't make any sense. This device just transports energy. It is almost exactly like a radio, it gives off electromagnetic waves. Also the person who wrote this article has no idea what they are talking about. Electromagnetic waves have both ELECTRIC and MAGNETIC components, each providing an equal amount of energy.

this technology will increase the power loss and use the extra energy and also harm the human body like the electromegnetic waves do and the intruption will be created throgh different devices that uses electromagnetic waves
quid @ Feb 5th 2008 10:50AM
Jay Doll, you are unbelievably stupid. Screw the arabs? This is a way of transmitting energy, not a source of energy. We will be dependent on arab oil for a while yet.
