The future: The device that is capable of harvesting microwave signals from the air consists of five fiberglass and copper conductors wired together on a circuit board.

Engineers at Duke University have designed a breakthrough gadget that 'harvests' background microwave radiation and converts it into electricity, with the same efficiency as solar panels.
The development, unveiled on Thursday, raises exciting possibilities such as recharging a phone wirelessly and providing power to remote locations that can't access conventional electricity.
And the researchers say that their inexpensive invention is remarkably versatile. It could be used to capture 'lost' energy from a range of sources such as satellite transmissions, sound signals or Wi-Fi.
