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

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

But what about if we did the same aournd the moon! It would work at night too!

Wiki def Dyson Sphere:

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.
