Circular dome colony over a very large rotating space, running on concentric rings of superconducting rails. Spokes of slidable inner-outer weights to counter balance its residence’s movements. Running on reliable constant nuclear power, from a safe distance. Maximum gravity at the tilted edges. Only natural gravity at the center. Enter & exit from a tunnel that connects under the center. Aside from the challenges of location & distance from Earth, if we can build small mobile cities on water (mega cruise lines) on the untamed ocean in Earth gravity, surely a small stationary spinning platter city in low gravity is possible. I think humans are going to find out that one g has many uses besides health. Good for a lot of manufacturing too. Gravity is a stabilizer, vertical organizer, anchor. Just as low gravity will have many advantages. Being able to quickly “adjust” gravity, by moving location, will be significant.
