Powercast transmists RF energy to a receiver module measuring about half the size of a AAA battery. CNET described, “It works like this: a transmitter can be placed anywhere—in a lamp, for example, that is plugged into the wall and sits on a table. The transmitter in the lamp sends out a continuous, low RF signal. Anything with either AA or AAA batteries set within its range—and equipped with a Powercast receiver, which is the size of your fingernail—will be continuously charged.”  After three years of keeping its technology under close guard, Powercast has come to CES 2007 to get consumer and manufacturer attention. 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.
While it's presented as wireless power, Powercast isn't just a replacement for a universal charger. Instead, it's meant to either continuously charge a battery or replace the need for them altogether.
