Witricity is based upon coupled resonant objects to transfer energy between objects without wires. The system consists of a Witricity transmitter, and devices which act as receivers.
Like radio receivers, the devices must be in range of the transmitter. Unlike the conduction-based systems built by Nikola Tesla in the late 19th century, Witricity uses resonant magnetic fields to reduce wastage of power. Currently the project is looking for power transmissions in the range of 100 watts.
As they put it: "Using self-resonant coils in a strongly coupled regime, we experimentally demonstrate efficient non-radiative power transfer over distances of up to eight times the radius of the coils. We demonstrate the ability to transfer 60W with approximately 40% efficiency over distances in excess of two meters. We present a quantitative model describing the power transfer which matches the experimental results to within 5%. We discuss practical applicability and suggest directions for further studies."

But he was working with J.P. Morgan. Teslas idea conflicted with J.P.s to wire the world and get rich doing so. So Morgan having more money, being more powerful, blacklisted Tesla and tore down all his work. Without funding, Tesla could'nt do anything about it. Tesla died January 7th 1943. My question is why has noone ever looked deeper?
I'm currently 16 and I am really interested in electricity, especially lightning. I love lightning storms. I quite often think about harnessing the power of lightning and the power from the atmosphere. I also seem to know a lot more about electricity than most people my age. I am very interested about wireless energy transfer as well as radio waves. I'm not very good at math and I remember reading something about how Tesla was never good at math as a child as well. Don't remember where I read that at.
i want to perform a little project on witricity i.e. wireless electricity Witricity: go witric!
I was reading an article online saying the new iPhone 5might last 30 days on a full charge because of some new liquid metal type of material in the battery that is suppose to power the iPhone for 30 days without recharging. Is this for real? When will we have wireless electricity? Witricity powered: explain witric..

can someone explain how this guy did this project? values of the components.. a circuit diagram would be awesome. im stuck on my wireless electricity project. please help.. Witricity powered: explain witric..
I am going to be in the 11th grade next year after summer and was wondering what electives I should take. I am still trying to decide what I should be when I grow up as well. I am really interested in how stuff works. I often times take stuff apart and put them back together again (or at least try to), I've been really interested in radio waves and electricity and how it works. I've always been fascinated by static electricity and flight, I've always wanted to fly, it is my dream. Recently I've been fascinated by the works of Nikola Tesla's.
Just wondering, I was just getting a little tired of always plugging in my laptop and all these other appliances. Is it possible to have wireless electricity.... ever?
Because that would be awesome (: Witricity powered: witric power.
m trying to make a project on wireless electricity , for which i need to couple two coils of same resonant frequency , for what I've came across the internet , it looks like its done by using parallel LC circuit , so my question is why the parallel LC circuit , why not series LC circuits coupled to transmit power as signals are transmitted in radio transmitters ? Witricity powered: explain witric..
