Microwave power transmission and helicopter technologies have been successfully combined to produce a hovering vehicle which is held aloft solely by power derived from a microwave beam. New efficient, and lightweight antenna and rectifier technologies allow the helicopter to support its energy-capture system and a substantial payload in addition to its own weight. In more detail, a microwave-powered helicopter with a six-foot rotor has been flown at an altitude of fifty feet for ten continuous hours. The helicopter was kept over the microwave beam by means of a suitable tethering system. (Author)
