How Space Solar Panels Could Power the Earth With 24/7 Clean Energy

How space solar panels could power the Earth with 24/7 clean energy:

Solar power has been a key part of humanity's clean-energy repertoire. We spread masses of sunlight-harvesting panels on solar fields, and many people power their homes by decorating their roofs with the rectangles.

But there's a caveat to this wonderful power source. Solar panels can't collect energy at night. To work at peak efficiency, they need as much sunlight as possible. So, to maximize these sun catchers' performance, researchers are toying with a plan to send them to a place where the sun never sets: outer space.

Theoretically, if a bunch of solar panels were blasted into orbit, they'd soak up the sun even on the foggiest days and the darkest nights, storing an enormous amount of power. If that power were wirelessly beamed down to Earth, our planet could breathe in renewable clean energy, 24/7.

[...] In the early 1900s, Russian scientist-mathematician Konstantin Tsiolkovsky was steadily churning out a stream of futuristic designs envisioning human tech beyond Earth. He's responsible for conjuring things like space elevators, steerable rockets and, you guessed it, space solar power.

Since Bell Labs first invented the first concrete "solar panel" in the '50s, international scientists have been working to make Tsiolkovsky's sci-fi fantasy a reality. They include Japanese researchers, the United States military and a team from California Institute of Technology spearheading the Space Solar Power Project.
