So, what are they harvesting on the moon? Helium3 extracted from the lunar dust? Or are there tube farms under the surface? 

Do they use electromagnetic catapults to fling the exports to Low Earth Orbit? Or do they splash down in the ocean? Is there a beanstalk?

Is the city domed? Underground? Or exposed with cheap radiation shielding? Any green areas?

Do they use Newts as part of the atmospheric supply system? Are we going to be eating a lot of newt nuggets?
