Can solar power plants be built in space?

Solar power plants in space, although difficult to build, would produce energy 13 times more efficiently compared to those on Earth, as their view of the sun is not obscured by atmospheric gases. Join our Space Forums to keep talking space on the latest missions, night sky and more!

What is space-based solar power?

The idea of space-based solar power dates back to as early as 1923 when Russian theorist Konstantin Tsiolkovsky proposed using mirrors in space to concentrate a strong beam of sunlight down to Earth.

Can solar energy be used in space?

Could a solar power plant power more than a million homes?

A single CASSIOPeiA plant could power more than a million homes, researchers estimate. Solar power plants in space, although difficult to build, would produce energy 13 times more efficiently compared to those on Earth, as their view of the sun is not obscured by atmospheric gases.

Could a solar farm be built in space?

Here’s how it would work – and the benefits it could bring Solar power systems on Earth can only produce energy during the daytime. Diyana Dimitrova/Shutterstock The UK government is reportedly considering a costly proposal to build a solar farm in space.

Is space based solar power a good idea?

The World Needs Energy from Space Space-based solar technology is the key to the world's energy and environmental future, writes Peter E. Glaser, a pioneer of the technology. Japan's plans for a solar power station in space - the Japanese government hopes to assemble a space-based solar array by 2040. Whatever happened to solar power satellites?
