- A physically realizable Dyson Sphere would probably be built
- piecemeal. If you're constructing it out of small, independent bodies
- (such as large numbers of O'Neill colonies) then it makes perfect
- sense to build it one orbiting body at a time, as you need living
- space / energy. Each thing you put in orbit requires manufacturing and
- maintenance, so there's incentive for doing as few as possible.

- Yes, and Dyson's original article described the type of Dyson sphere I
- have mentioned here, not a solid shell at all. So, pedantically, a
- constellation of orbiting powersats is a Dyson Sphere.
