conceived in 1968 by peter glaser, this would harvest energy from sunlight using solar cells and beam it down to earth as microwaves to huge rectennas, which would convert it to electrical energy on the electric power grid.

in 1964 brown invented the rectenna which could efficiently convert microwaves to dc power, and in 1964 demonstrated it with the first wireless-powered aircraft, a model helicopter powered by microwaves beamed from the ground.
