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.

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.
saurabh agrawalJan 9th 2009 12:47AM
hey nice blog thanku providing info this witricity project can be a nice project at a btech level altho its old thing but a new age demand. it will be great if some1 help me out in dicussing the input to the transmiter let me tell my idea of trying this out. i m going to design the transmitter no prbs as well as the reciever but where the problem i m facein is fram where a supply of 10 MHz is going to be taken so i thought of frequency modulating electricity (but i also doubt that is it possible) cuz the amplitude of electricity is very high and how do i design a circuit that could tolerate that high amplitude. any ways if i m able to get a supply of 10 MHz then then next prb would be of the ocsillator so i thought of using a crystal oscillator of 12 MHz available in market and the same frequency supply(for resonance) now before i try this if some1 reads this comment plz help me out if u think some thing is wrong or any modification is needed............
rageshp1989Aug 28th 2009 9:33AM
sir could u please help me in how to implement it practically

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?
CincyJoeJun 9th 2007 9:42AM
I would call it Wi Tri (Y TRY)
lolaJun 9th 2007 3:33PM
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?
Jay dollJun 9th 2007 5:37PM
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.
MikeJun 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.
SALVATOREJun 11th 2007 2:25PM
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 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 would effect people the same way power lines would.
Terrence O\\\'BrienJun 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.
Barbara LindseyJun 12th 2007 9:40AM
"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)

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
