Powercast: You dont have to CHARGE those BATTERIES
Worried of getting that “iphone” which dies after 2 hours or so? Taking that party video only to realize your battery is crap? Here’s an answer for you. Powercast. Almost three years in the making, powercast is a radio frequency that is transmitted over a small area, and its energy is “harvested”–wirelessly–to give power to small devices like cell phones. It’s meant to either continuously charge a battery or replace the need for them altogether.
How does it work then? Well, you need a transmitter that is plugged into the wall. The transmitter sends out a continuous, low RF signal. Batteries within its range equipped with a Powercast receiver will be continuously charged.
Products with Powercast are expected 4th qtr this year (2007).
