Wireless charging through laptop!

Intel has conceived a new idea of wireless charging of cell phone with the help of a laptop. This idea has  been demonstrated on an Acer laptop. Now, there is no  need of carrying charging cable or mats with you! The prototype ultrabook sets the phone on charging when the phone is placed near it.
There is a pair of transmitter, one in the laptop and the other in the phone.  The charging takes place through electromagnetic induction. The laptop's transmitter produces a varying magnetic field that induces a current in the transmitter of the phone. This charges the phone.

Charging starts as soon as the phone is placed near the laptop with an audio "ping" and a desktop notification of charging.
