The rate of construction by the space manufacturing facility is 32.2 t / (mo. s.m.f), so the construction of the large mass driver reaction engines takes Since the space manufacturing facility reaches the 10^ t/yr. construction rate at month 53, then takes 3 months to construct the large mass driver reaction engines, then 12 months more to complete the first solar power satellite, and the large mass drivers take 5 months to deliver the solar power satellite to geosynchronous orbit, the solar power satellite arrives at geosynchronous orbit at month 53 + 3 + 12 + 5 = 73, or 6 yr., 1 mo., when power reception by earth begins. All discussion of equipment is now complete except the mass from earth for the copies of the space manufacturing facility. 258 copies of the space manufacturing facility are produced by the original, all of which require 0.1 of their mass from earth. Since the space manufacturing facility copies have mass 58 t, the mass from earth for space manufacturing facility copies is
