I read the closest we could likely get to this, in a sci-fi story years back. A habitat on Mercury. It sat on a rail that circumnavigated the planet. The heat of the sun caused the rails to expand, pushing the city forward. This kept it in the most habitable zone, as the planet turned (Mercury has a day longer than its year).
Not quite a zorb, but definitely a clear dome rolling around the planet.
Habitat zorbs that bounce around the planet.
I love this image. Solarpunk future where THIS is society!
