We knew it was just a matter of time. Wireless electricity. Now finally it is here!

A group of scientists at MIT have demonstrated what they are tentatively calling “WiTricity” – the ability to send significant amounts of electricity through the air without the use of wires. For many this has been the holy grail of achievements and could signal a new revolutionary wave of development in the consumer electronics industry.

“The inspiration came when the lead researcher, at the Massachusetts Institute of Technology, Dr Marin Soljacic, was standing in his kitchen at night staring at his mobile phone.

It was probably the sixth time that month that I was awakened by my cell phone beeping to let me know that I had forgotten to charge it. It occurred to me that it would be so great if the thing took care of its own charging,” he said.

The concept works by using the principles of electromagnetic induction where you pass electricity from one coil to another. It’s a transmitter/receiver arrangement of sorts and is already being used in many applications today – except that typically the transmitting and receiving coils need to be very close together. In WiTricity, the system basically fills the room with a ‘non-radiative’ electromagnetic field. To objects that aren’t designed to resonate with the field (plants, desks, walls, your grandmother Lois) the field simply passes by harmlessly and is ignored.

 

So no more those annoying wires and everything really go wireless.. hehe.. Neighbours can “tmpang” ur electric also >.< So gotta put password on our electric as we did with our router? =.=”
