However, researchers believe that a rectenna with commercial potential may be available within a year. Given that the devices are made with vapor deposition nanotechnology techniques, they might ...

These six by 13-kilometre stations – about 8% the size of a wind farm – have massive receivers called rectenna that convert the radio waves into electricity. The rectenna works by harvesting ...
