Nonsense. To make orbital solar a reasonable solution you have to posit cheap orbital transport.
It could posit room temperature superconductors and solve the same problem with a world wide electric grid and rooftop solar. America could supply it's energy needs with infinite capital and it's roof tops (in gross, not time specific).
Adults understand that energy supply will continue to be from a mix of sources and that there is no magic bullet.
