It has been proposed that solar collectors could be deployed in space, and that the collected power could be beamed to Earth using microwaves. A potential limiting factor for this technology would be the possible hazard of human exposure to the microwave beam. One proposal involves a circular receiving array of diameter 10 km for a transmitted power of 750 MW. Compute the energy flux in this scenario and compare to the energy flux of solar radiation.
