Abstract

The National Aeronautics and Space Administration has been studying the feasibility of orbiting a Space Solar Power Laboratory at synchronous heights. The laboratory would be equipped with a 65 km˛ solar-cell array, a 2.3 GHz, 10 GW transmitter, and a narrow-beam antenna. The steerable antenna beam can be oriented toward any region of the earth's surface within line of sight with power density as high as 100 to 1000 Wm−˛ at the earth's surface. By retuning the transmitter to 22.2 GHz, a substantial amount of energy can be transferred to the atmosphere via absorption by atmospheric water vapor, water droplets from clouds, and rain droplets, as well as to the lossy terrain. These mechanisms have the potential of causing substantial atmospheric weather modifications for example, the dissipation of fog layers or the amelioration of severe atmospheric pollution.
