Physicist Hatem Zeine has invented what he believes to be the answer to this challenge. The Cota wireless power transmission system uses intelligently steered phased array antennas to focus a beam of microwaves on a receiver module – and only on that module. The inherently safe technology can deliver electrical power up to 30 feet from a central transmitter without any line-of-sight requirement and without interfering with other devices. The system is projected to hit the market in 2015.

 

At Tech Crunch Disrupt 2013, Hatem Zeine pulled the curtain on the Ossia, Inc. development company by introducing the Cota wireless power transmission system. The Cota technology uses steered phased array microwave antennas and the time-reversal properties of electromagnetic radiation to focus several watts of power on a wireless receiver while preventing any of the radiation to hit obstacles, resulting in an inherently safe charging system.
