HOW WIRELESS POWER-Witricity WORKS

HOW WIRELESS POWER WORKS 1. Magnetic coil (Antenna A) is housed in a box and can be set in wall or ceiling. 2. Antenna A, powered by mains, resonates at a specific frequency. 3. Electromagnetic waves transmitted through the air. 4. Second magnetic coil (Antenna B) fitted in laptop/TV etc resonates at same frequency as first coil and absorbs energy. 5. Energy charges the device.

A system that can deliver power to devices without the need for wires has been shown off at a hi-tech conference.
