A Pennsylvania start-up says it has the answer to one of the biggest problems in mobile phones: battery life.<\/p>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
“Our solution is, if talk time (on a cell phone) is 5 1\/2 hours, by trickle-charging (it) at work, now talk time is 10 hours because the battery never gets to dead,” John Shearer, CEO of Powercast, said in an interview.<\/p>\n
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.<\/p>\n
Major CE and IT manufacturers will have to agree to build Powercast capability into their products, and thus far Powercast is revealing only Philips as a future partner. The first Powercast product will come to market by the end of 2007, the company says.<\/p>\n
