Gallery: New Solar Satellite Could Harvest the Sun’s Rays 24/7 From Out...


Since the early 1970s, scientists have been toying with the idea of collecting solar power in space, where solar collection rates are stronger than on the surface of the Earth. But because of the costs and technical challenges involved, the concept still remains in the realm of science fiction. That all could change with a new proposal from John Mankins from Artemis Innovation Management Solutions, who claims to have come up with “the first practical solar-power satellite concept.”

    Guys? How do you get the electricity down to earth? That’s always been the hangup. Once you figure the efficiency of magnetrons (or transistors, even worse), antennas, and diodes, you’re not competitive with earth based solar arrays, and nobody wants those megawatts radiating on their back yard.
