random discussion yay

Dyson Sphere is a hypothetical system that involves a bunch of satellites surrounding a star to capture it's energy, and allow people living inside the Dyson Sphere to use that energy, pretty much. It gets more complicated I suppose.

Would we be able to create such a system in the future, and how long do you think it would take us right now if we were to build one this instant?
