A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone. Because only a tiny fraction of a star's energy emissions reaches the surface of any orbiting planet, building structures encircling a star would enable a civilization to harvest far more energy.

Thanks because I legitimately thought it was one of those fancy vacuums or fans.

Yeah, it didn't make sense in my head, felt like I was also missing something so I went and learned about it

The benefit of it working only in the daytime means you can build it at night though

I saw that comment on a link here to the wiki page for Dyson spheres. Wonder who copied whom.
