WiTricity

* It is wireless electricity.

* The key technology behind this is to make the recharding device and
the device that needs power to resonate at the same frequency. This
allows them to exchange power efficiently.

* The power source is kept at a distance of 2 meters from the bulb in
this experiment.

* The word `witricity' was coined back in 2005.

* Witricity exploits the coupling between electromagnetic resonant
objects to transfer energy wirelessly between them.
