This article was written way back in 2007 and I suppose it is still relevant and in fact Nokia already used this technology to charge their Nokia Lumia phones.
Below is the original articles written by me , 7/15/2007 and published at 8:45PM.
Imagine one day when all electronics product such as PCs, Hand phones and many others devices will be run with out battery or power cord.
This may sound futuristic but the day will come very soon. Researchers at MIT have successfully tested a system for transferring electricity to remote devices without wires, allowing portable devices to recharged or powered without the use of power codes. They name this system “WiTricity”.
Last week, an MIT research team announced that it had juiced up a 60-watt light bulb using "WiTricity".

The WiTricity operates using two copper coils, one attached to a power source. The power coil emitted a field of magnetism to the unpowered coil, stimulating it to generate a current that powered the light bulb from seven feet away.
The WiTricity generated by the coils powered the light bulb in a way similar to magnetic induction, which is used in power transformers so that one coil carries power to another.
Features of Witricity:
a) Coil can be configured to provide power to several devices such as laptops, handphones.
b) Contain no toxic chemical unlike battery.
c) Safer than electricity.
d) Run forever if you take care of it.
e) Does not require power cord.
f) A single Witricity can powered several devices.
The MIT teams said that they are working to make it more efficient, able to cover greater distance, generating more power and most of all will be commercially available in a few years time.
So there you are folks. That is definitely good news isn’t it. Imagine using a laptop without power cord throughout the day or even driving an electric car with out battery.
