An excerpt from the June 14, 1969 issue of "Science News" is presented speculating that solar cells placed on the surface of the moon could beam power to the Earth using lasers and produce upward of 100,000 megawatts of power and mentions plans by various nations to launch solar power stations into space.

Reports that solar power satellites orbiting the earth will convert the sun's energy to microwave energy and then transmit them to receiving installations on the earth. Description of the photovoltaic approach used by the satellites; Complexity of the thermal design of transmission; Environmental concerns related to the effects of the beams transmitted to the earth; Role of rectenna, a microwave receiving antenna.

Reports on possible environmental effects of solar power satellites which are used to provide energy to the earth from orbit by microwave relay. Estimated amount of power to be generated by one solar power satellite; Reference to a study conducted by the U.S. Department of Energy and National Aeronautics and Space Administration on the issue.
