WiTricity. The Wireless Electricity

It was just yesterday when I was thinking that even if we manage to go wireless for everything connected, one thing is there for which, one has to use wire – the mother of all those wireless devices, electricity. The thought came to my mind when my laptop ran out of power and it had to be connected to plug, no matter how deliberately I was enjoying wireless connectivity.


And today I came across this news which goes like – We’re One Step Closer to Wireless Electricity. It is referring to M.I.T research which showed transmission of enough power to lit a 60-watt light power in a room. The technique is names as WiTricity.

The feed is referring to a newspaper article which says –


WiTricity could get cords from under foot


Last week, Soljacic and fellow team members from MIT’s Department of Physics, Department of Electrical Engineering and Computer Science and Institute for Soldier Technologies reported they successfully lighted a 60-watt light bulb from a power source more than two meters away, with no physical connection between the source and the appliance.


With “WiTricity,” cell phones, MP3 players, laptop computers and many other portable electronic devices could soon charge themselves without ever being plugged in–or even operate without batteries at all.


Still, the MIT team says power sufficient to run a laptop, can be easily transferred over room-sized distance even if line-of-sight is obstructed: in other words, as long as a coil-equipped laptop is in a WiTricity equipped room, its battery could charge automatically, or it could operate without a battery or being plugged in.


My eyes are glowing and you can notice that :cool:!
