How does space solar power work?

Here’s how it works. A space solar power prototype has demonstrated its ability to wirelessly beam power through space and direct a detectable amount of energy toward Earth for the first time. The experiment proves the viability of tapping into a near-limitless supply of power in the form of energy from the sun from space.

Can space solar power beam power to Earth?

A space solar power prototype that was launched into orbit in January is operational and has demonstrated its ability to wirelessly transmit power in space and to beam detectable power to Earth for the first time.

How does a space solar power demonstration work?

The Space Solar Power Demonstrator's MAPLE experiment was able to wirelessly transfer collected solar power to receivers in space and direct energy to Earth. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

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.

How has SSPP changed space solar technology?

"SSPP gave us a unique opportunity to take solar cells directly from the lab at Caltech into orbit, accelerating the in-space testing that would normally have taken years to be done. This kind of approach has dramatically shortened the innovation-cycle time for space solar technology," says Atwater. MAPLE: Wireless Power Transfer in Space

How does solar power transmission from space work?

Here’s how it works. A first-of-its-kind lab demonstration shows how solar power transmission from space could work. The demonstration, carried out by U.K.-based startup Space Solar, tested a special beaming device that can wirelessly transmit power 360 degrees around.
