6 FAQs about [Solar powered satellites]

Who invented the solar power satellite?

Image: NASA. Image: NASA. Of all the many spaceflight concepts NASA has studied, the most enormous was the Solar Power Satellite (SPS) fleet. Czech-born physicist/engineer Peter Glaser outlined the concept in a brief article in the esteemed journal Science in November 1968, and was awarded a patent for his invention on Christmas Day 1973.

What is a solar power satellite?

1968: Peter Glaser introduces the concept of a "solar power satellite" system with square miles of solar collectors in high geosynchronous orbit for collection and conversion of sun's energy into a microwave beam to transmit usable energy to large receiving antennas (rectennas) on Earth for distribution.

How much solar power would a satellite generate?

A single solar power satellite of the planned scale would generate around 2 gigawatts of power, equivalent to a conventional nuclear power station, able to power more than one million homes. It would take more than six million solar panels on Earth’s surface to generate the same amount.

What is a solar power satellite (SPS)?

SERT went about developing a solar power satellite (SPS) concept for a future gigawatt space power system, to provide electrical power by converting the Sun's energy and beaming it to Earth's surface, and provided a conceptual development path that would utilize current technologies.

Are solar power satellites possible?

Parts of solar power satellite systems have been demonstrated on a small scale in orbit, but to make this technology truly feasible, technology developments are required in many different areas. For instance, we would need to improve our ability to manufacture and deploy very large structures, as well as to convert and transmit energy efficiently.

Do orbiting satellites need solar power?

Orbiting satellites can be exposed to a consistently high degree of solar radiation, generally for 24 hours per day, whereas earth surface solar panels currently collect power for an average of 29% of the day. Power could be relatively quickly redirected directly to areas that need it most.
