Wireless Power ...
Everything is going wireless ... At home, I now have wireless internet, wireless speakers, a wireless printer, a wireless headphone. And of course, my phones - Cell phone and Landline are wireless and of course Remote Controls are sort of wireless too.
The only thing that stubbornly remains wired is electricity. Having wireless power would just be the coolest. Of course, the concept of wireless power has been around for a long time (more than 100 years). Tesla was the one who came up with the idea.
The method he proposed to use to produce wireless power was to employ the earth's own resonance with its specific vibrational frequency to conduct AC electricity via a large electric oscillator. J.P. Morgan, the billionaire financier agreed to underwrite Tesla's project and a strange structure was begun and almost completed near Wardenclyffe in Long Island, N.Y.
It looked like a huge lattice-like, wooden oil derrick with a mushroom cap and it had a total height of 200 feet. Then suddenly, Morgan withdrew his support to the project in 1906, and eventually the structure was dynamited and brought down in 1917.
More recently, another method was tried.
Light was transmitted from place to place and then converted to electricity using photo-voltaic cells. The need for light transmission was because durid any point of time, there are regions on Earth that do not have sunlight.
However, these methods deal more with long distance transmission. I wonder what a good method would be to transfer electricity from the wall socket to my computer with no wires ....

What you refer to is similar to whats being used with passive RFID tags ...
