Here’s an idea we discussed in Episode #1 of the SciFi Ideas podcast.
As stated in the podcast, the Shell Worlds concept is the brain-child of engineer Ken Roy, who envisions the building of enormous air-tight spheres around small planets and moons to facilitate terraforming. Once completed, the ‘shell’ could be filled with breathable atmosphere, turning the body into an enormous biodome. Roy imagines the constructed ‘shell’ also being used as a foundation for residential and industrial facilities, with the surface being used primarily for agriculture.
The following infographic (created by Space.com) illustrates the concept perfectly:
