WiTricity: Wireless Electricity

Imagine a future in which wireless power transfer is feasible: cell phones, household robots, mp3 players, laptop computers, and other portable electronics capable of charging themselves without ever being plugged in, freeing us from that final, ubiquitous power wire. Some of these devices might not even need their bulky batteries to operate.

Well that future could be just around the corner; A team at MIT led by Prof. Marin Soljacic has experimentally demonstrated an important step toward accomplishing this vision of the future, they were able to light a 60W light-bulb from a power source more than 2 meters away, without any physical connection between the source and the appliance.

The MIT team refers to their concept as “WiTricity” (as in Wireless Electricity).

WiTricity is based on using coupled resonant objects. Two resonant objects of the same resonant frequency tend to exchange energy efficiently, while interacting weakly with extraneous off-resonant objects.

This is just so amazing and exciting, so practical, so useful and opening many doors to many other possibilities.

The future is wireless!
