re: Lunar Helium-3, and Orbiting Fusion Powerplants

Check out the size of the proposed fusion reactor. It is expected that a single commercial fusion powerplant would be about 20 percent bigger, and mass a little under 50,000 metric tonnes. Eventually we might need about 50 of these systems orbiting Earth, supplied by Lunar He-3 fuel, with microwave-beam transmitters to supply power to orbiting heavy-lift ARMXERs:
