Solar Power Satellites have long been seen as a key industrial application for space and, though their practical economics have been difficult to realize in the present, they will likely become a common fixture of space development across the Asgard phase, employing variations on the structural systems and technology of Modular Unmanned Orbital Factory - MUOF facilities. As space facilities of different kinds spread across the solar system, and particularly into deeper space, many will demand more energy than can be effectively produced locally from solar energy at their outer orbital locations. Many may rely on nuclear power but ultimately it will become necessary and practical to relay energy gathered from large dedicated energy systems closer to the sun in solar orbits These would use l
