Nearer-term Laser-Photovoltaic WPT options are less efficient, but allow synergistic use of the same photo-voltaic receiver for both terrestrial solar power and SSP. The smaller aperture size also allows smaller (lower cost) initial systems. Laser-Photovoltaic WPT systems open new SSP architecture options. Gravity gradient-stabilized Sun Tower SSP satellites may make more sense for laser systems than than for microwave systems, because the receiver also converts sunlight into electricity, to correct for the cosine loss otherwise observed in power production at mid-day. Technology flight demonstrations can enable advanced space science and exploration in the near term. Power Plug or LAMP spacecraft and Lunar Polar Solar Power outpost advance technology for far-term commercial SSP systems, while providing significant value for near-term applications.
