In a perfect world, there'd be no wires.
Massachusetts Institute of Technology researchers announced that they
had made a 60-watt light bulb glow by sending it energy wirelessly,
potentially previewing a future in which cell phones and other
gadgets get juice without having to be plugged in.
The concept of sending power wirelessly isn't new, but its wide-scale
use has been dismissed as inefficient because electromagnetic energy
generated by the charging device would radiate in all directions.
How it is done?????

How it is done?????
The key is to get the charging device and a gadget to resonate at the
same frequency _ allowing them to efficiently exchange energy.
it is similar to how Tansen could create sound from 17 tablas just by
it is similar to how Tansen could create sound from 17 tablas just by
hitting one of them (He matched the natural frequency of other tablas
thus resonating them at same frequency)
In fact, the concept is so basic in physics that inventor Nikola Tesla
sought a century ago to build a huge tower on Long Island that would
wirelessly beam power along with communications.
