In the aftermath of the ’70s oil crisis, Boeing designed a solar power satellite system that could supply most of the the United States with electricity. Boeing’s plan envisioned satellites the size of small cities placed in geosynchronous orbit, transmitting electrical energy back to Earth as microwaves. The satellites would either be constructed in low Earth orbit for later deployment into a higher orbit or constructed directly at the higher orbit.
