Analogies with industrial development and with the Saturn, Shuttle, and Skylab programs demonstrate the feasibility of Solar Power Satellites (SPS) that require space launch rates countable in flights per day, systems with very large mass and size, and large-scale construction techniques in orbit. SPS energy production is estimated to equal 400,000 barrels of oil per day throughout an SPS operational life of 30 years or more; low transport costs to low earth orbit and on to geosynchronous orbit are projected as a result of: reusability of vehicles; high traffic volume; relatively rapid ground turnaround; and large payload capacity. Construction procedures and installation of reflector systems are discussed, and diagrams of fabrication methods and devices are presented. About 10 manhours would be needed to erect one ton of material, and a workforce of 500 to 700, working 10-hour shifts 6 days a week during a 90-day orbiting period, is projected.
