I’ve been meaning to blog on this for the last couple days and didn’t get the chance. I think it is the best thing to come out of the Consumer Electronic Show. The weakest link in a life filled with gadgets is the power supply, you need all these different charges and it’s very annoying because you keep misplacing them. But now that may change:

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.

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.

There are many applications for Powercast, said Shearer, but the company is making the PC peripherals market a priority. Think a wireless keyboard or mouse with no battery, or a hermetically sealed battery that the customer never need access again.

I want it now, I don’t want to wait. I hope it isn’t too expensive.
