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."

Is this true? Is it scientifically feasible? Witricity powered: a witric one!
Im buying a gaming laptop and here are the descriptions of the two laptops i need to know which is better for gaming
The ASUS G74SX-3DE 17.3-Inch Gaming Laptop - Republic of Gamers (Black) Specs:
Im wanting to buy a laptop to play new MMORPG's that are now being released... i'm worried this laptop won't handle these new games.. Please give me feedback... ty here are its specs
I had given on Wireless Electricity Transmission
Now i need Topic like that which is very hot and interesting in point of lecture & research and Listeners... Witricity: witric power.
my knowledge about tesla was that we refer tesla as unit of mesauring magnetic field. then i found many intesting facts about him in internet. tesla was way ahead of his tiime we know he discoverd ac power. but article i read says that he actually was sucessful in transmittimg electricity without wire it aslo says that he actually wanted to build gaint tesla coil gentrating huge enough electricity to split the earth .then he aslo was sucessful in transmitting message wireless in 19th century but died under mysterious circumstance in new york.
I had to switch the electricity off and when it came back on there was no internet connection at all. Reset the router about half dozen times~now working with the yellow ethernet cable but there is still no wireless network showing (the neighbours' ones are). Orange/amber light is flashing (O2 wireless ll router). Tried the wireless button on the front but daredn't reset again in case I lose the whole connection again. Any ideas?? Contacting O2 online is a waste of time~just giving set answers that I can find on google which mean nothing to a simpleton :) x
