The industry required in space to produce SPS components is relatively modest. The silicon solar cells can be made from lunar or asteroidal silicon, as silicon is the second most abundant element on the Moon and likewise in many kinds of asteroids. The waveguides could be made of glass ceramics. The vacuum tubes to generate the beam could be largely steel in terms of weight, with the small electrodes perhaps imported from Earth depending on the level of effort we put into processing the different kinds of asteroidal materials. Given the advantages of manufacturing semiconductors in orbit, Silicon Valley could lose big business to competition from Silicon Orbit in the future.
Computer chips are small and lightweight enough to bring back to Earth.
A future generation of space-made chips may start to bring a close to many kinds of chip manufacturing on Earth, to the benefit of consumers and Earth's environment. The first to go into business making silicon solar cells in space may well become the first to dominate that business. That may be judged by the first to experiment in orbit and get patents.
