Airnergy Charger Gets Power From WiFi Signals
RCA's Airnergy Device Charges Gadgets By Harvesting Energy From Wifi Signals
Gadgets have been powered by many means over the years, from the humble plug to the battery to wind-up radios. But now one company thinks it can take things a step further – and pluck power from the air simply by harnessing Wi-Fi signals.
The pocket-sized gizmo, which resembles a 3G dongle, carries a complex series of circuits that converts a Wi-Fi signal into energy and stores it in its own battery. It can then be plugged into any mini-USB connector to provide a secondary power source.
The gadget, which is scheduled to go on sale in the US later this year for $40, was released at the Consumer Electronics Show in Las Vegas.
