RCA Airnergy Charger Harvests Electricity From WiFi Signals

RCA recently showcased a new charging product called the Airnergy Charger that collects Wi-Fi signals, converts them to electricity, and uses that electricity to power a small internal battery. The charger can then be plugged into a device such as a mobile phone via USB and provide it with a charge. The device is always on and collecting Wi-Fi signals, so it is always charging (when near Wi-Fi hot spots).

Measuring smaller than the size of a palm, this tiny Airnergy Charger can harvest surrounding WiFi energy and convert it into electricity for practical use. The energy will be stored in a rechargeable battery located inside it and used to charge electronic gadgets. At the recent CES, RCA demonstrated that Airnergy is able to fully charge a BlackBerry with only 30% power remaining within 90 minutes.
