      True, but if we expanded our scope to all the space dust in the cubic light-year the sun occupies the center of, we will have enough material to build between 10-29 solar systems, complete with their own stars, so that’s probably enough material.

      But we could build a Ringworld, and then we can spin it for gravity, add shadow squares for a day-night cycle, and not have to rely on artificial gravity generators to prevent us from falling into the sun!

      Depends how you do it, if its just a thin reflective foil focusing light on a few collectors then we could probably do it inside a century on just the worlds current production capacity. (baring actually getting all the foil there and engineering collectors and so on, just talking making the foil itself here)
