How To Harvest A Star's Entire Energy Output

Stars give off loads of energy. In theory, we could capture most of that energy if we managed to surround one with solar panels. This could be accomplished by encasing the star in a massive solar panel megastructure, called a Dyson Sphere. A more practical option might be a Dyson Swarm, which would instead be composed of numerous free-floating solar panels that orbit the star.
