Build your own ice dome on the moon

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.
