Reason

The basic premise of the story Reason just may become a reality... The Pentagon’s National Security Space Office (NSSO) wants to look into the possibility of a solar-power collection satelite. Huge arrays of solar panels would collect energy that would be beamed back to earth. Also, the article says that they want to make is powerful enough to be useful, but weak enough to not cause damage on earth. Minus the robots, sounds like Asimov was on to something.
