We have seen Wireless charging solutions like Palm Pre Touchstone and eCoupled, both of which requires devices (power provider and the device being charged) to be in physical contact with each other to transfer electricity which is not exactly the picture which comes to one's mind when hearing the term "Wireless Charging".

Cota is the name of brand new revolutionary technology which will deliver the expected behaviour of a real "wireless charging" solution, Cota can transmit electricity wirelessly at up to 30 feets and that to focussed at a particular device using radiation safe as WiFi signals. The Cota technology consists of a charger and a receiver, the inherently safe technology can deliver wireless electrical power up to from a central transmitter to multiple devices. Receivers will be built into devices or batteries which will get automatically charged, imagine the utility where you can simply buy a Cota enabled standard battery, inset into your device and forget getting bugged about charging/replacing them. Do watch the video demonstration shared below to see this in action.
