Wireless Electricity RCA has developed a prototype of a cool new gadget capable of producing wireless electricity from radio frequencies in the air. According to a company spokesman at the Consumer Electronics Show in Las Vegas, the device recharged a Blackberry from a 30% battery charge to full charge within 90 minutes. The handheld wireless device (Airnergy) uses an antenna to absorb energy from frequencies and convert them into DC power inside its casing. The gadget is then connected via a USB port to charge your cell phone or mobile internet device. Airnergy charges itself 24/7. This product is expected to be available later this year.
