Having a smartphone with Wi-fi capabilities, you immediately realize just how wide spread wifi networks are nowadays. From open hotspot networks, to private, secured networks, no matter where you go it seems like you can pull up 2-3 wireless networks (often with a broadcasted SSID).

Imagine being able to use the wireless signal to generate electricity, and then to take that electricity and use it to power your gadgets. Well,RCA's Airenergy device can do just that.
