It does work. It has been proposed to use this method to transfer
power from giant geostationary satelities to gian antena resembline
wire fences. Levels of RF energy would be low enough to allow
agriculture and not effect birds.

Solar energy is twich as high and it never varies day or night so about
8 times as much to receive in 24 hour period.

Several nations have also tested small unmaned aircraft or helicopters
powered by such beams. Antena can be a simple as a printed ciruit
board with diodes.

Magnetrons and travelling wave tubes are fairly efficient but I believe
silicin carbide is the way to go now.
