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."

in which country wireless electricity transmission is used why it is not using in india as we are using tesla coil which produces high voltages what are its demerits Witricity: witric power.

Not practical? Why? Because JP Morgan Chase didnt know how to make money off FREE? Witricity: witric power.
I love the idea of wireless electricity, but I'm confused as to how they are going to charge for the service. Flat rate? Some other sort of reader? And what's to stop my neighbor from stealing my electricity? Witricity powered: a witric one!
Like laptops accessing wireless internet, does anyone know about wireless electricity - Is it available or how long will it take or how far are we in in the research.
Friends I am talking about 'wireless' ELECTRICITY...ELECTRICITY Witricity: go witric!
So there this science fair me and my friends are taking part in. We want to do something related to wireless electricity. We were thinking of using SOMETHING to light up a low power bulb or CFL. I researched and landed up with these ways-
1. Use a tesla coil
2. Use two Biflar Coils.
3. Use a square wave generator.
If Tesla wanted to build a huge electric factory that supplied wireless electricity to people who needed electricity then if that was built would it be able to supply electricity to electric cars and so electric cars would be able to run infinite amount of mileage?
no not in the trunk i mean tesla tried to build one of these giant coils but jp morgan shut it down since someone beated tesla in build the radio. however the tesla coil was able to give electricity to light bulbs i beleive so why not build a huge tower on land and supply a city with this coil Witricity: a witric one!
I have a project about wireless electricity, just like this: http://www.instructables.com/id/Wireless-Power-Transmission-Over-Short-D...
uhm.. for this project, I want to ask those who know electronics better: Could I use the 'function generator' from my sound card to transfer electricity? (using this program: http://www.edn.com/article/CA46108.html ; or this http://www.vernier.com/labview/software/functgenapp.html)
THANK YOU VERY MUCH! [This is very urgent.. need answers in 3 days.. THANKS! :D ] Witricity powered: explain witric..
which will consume more Electricity ? ( Rs /month )
1) a zero watts bulb or a LED
2) LCD TV,LED TV,PLASMA TV or a CRT TV
( same size )
3) Window AC or Split AC
( same capacity )
4) Will a Fan regulator Reduce my electricity when it is minumum.
5) How to calculate load balancing in 3 phase wiring
6) Can i use a common Stabilizer for home in the AC Mains itself.
7) is wireless electricity possible when it induces a large magnetic field.
8) can we produce electricity by heating a filament.
9) how should i wire my generator to the ac mains
