Boxes face the same lifting force problem.
Burying it (dome or box) below enough dirt can alleviate the problem, but it's a lot of dirt.
Or you just make the structure with a lot of tensile strength. Run wires from the floor to the ceiling to hold the ceiling down.
- bloopernova 6y agoI've read "somewhere" that hollow lava tunnels/tubes could be used. Coat the inside with the plastic mentioned in the blog shared in another comment, and you possibly have an airtight (except for the soil) massive habitat. Although you'd have to string big lights along the top to grow plants.
- gpm 6y agoThis is a common idea - in a way it is as a shorcut to piling dirt on top of a structure that you make. Critics often bring up that exerting a huge force on the inside of lava tunnels might destabilize them in bad ways, and that sealing rough surfaces might be harder than just building a pressure vessel of your own.
