Researchers from Nihon Dengyo Kosaku Co., Ltd, (DENGYO) a Japanese communications infrastructure company, have developed a device they call the rectenna that can convert radio waves moving around in the air, to electricity. The name comes from combining the word rectifier (a device that is normally used to convert AC power to DC, but can also be used to detect radio signals) with antenna.
