ABSTRACT
Beamed micro wave power transmission may be thought of as extending our two dimensional power transmission networks to the three dimensional power transmission system in which power is beamed from earth to space or power collected in space is beamed back to the earth.
Solar energy is an unlimited source of energy. The electrical energy obtained from the sun by satellites in geostationary orbits is transmitted to earth. Unlike x-rays or ultra-violet radiation, microwaves are non-ionizing and are one million times too weak to cause harm. The only perceivable effect is heating, but since the power density of the beam near the receivers on earth is about 20 milliwatts per square centimeter, one-fourth of natural sunlight, the heat generated is so slight that a person walking through would feel nothing. Manufacturing costs are not a problem either since materials would be negligible (when compared with the relatively giant profits that a solar power satellite would generate).
