It is going to take some work as it is not currently that impressive but the experiment at Cornell University shows that power over WiFi is not impossible. The experiment was not all that impressive, they charged a Jawbone headset @ 2.3mA and after 2.5 hours which they managed to charge the battery to 41% over a distance of 5-7cm. Those results are poor compared to Qi and other wireless charging solutions on the market but are promising. The power is transmitted by a wireless router that can also send and receive data so for wireless cameras and other low powered devices which transmit data this could be quite useful. You can read the research paper by following the links from Hack a Day.
"There have been a few reports of power over WiFi (PoWiFi) on the intertubes lately. If this is a real thing it’s definitely going to blow all of the IoT fanboys skirts up (sorry to the rest of you *buzzword* fanboys, the IoT kids flash-mobbed the scene and they mean business)."
