I think the most efficient construction on the moon would be inflated structures constructed underground in the mooncaves.

Let the caves block the radiation and just focus on the thermal insulation and the air pressure integrity.

This means it would be possible to build large volume spaces, like sporting arenas.

And that’s the segue I need to share a deck promoting “Moonball.”

“A Modest Thesis on Moonball:

Billions of people will want to watch professional athletes playing sports on the moon. A successful event or sports franchise could fund economically sustainable human habitation by 2035.”

I would love any feedback on this totally modest proposal: https://docs.google.com/presentation/d/16QpeWjf1Hbxp_15D5Vtx...
