Ice Dome Construction for Large Scale Habitats on Atmosphereless Bodies
Well, I suppose this could be useful if they found a lot of underground ice in the shadowed areas near the lunar poles. Just start with a thin plastic film dome, inflate it a bit with nitrogen, and boil off the ice underneath to get it to sublimate on the film above. Then pressurise it underneath.
Make it a meter thick, and it would even be reasonably good for cosmic ray protection.
He's not talking tiny domes: 600 or 900 m diameter. I wonder how chilly you might have to keep the breathable atmosphere beneath it.
Neat, in any case.
