Underground housing, underground businesses, etc. Would that be better for the environment + possibly save on energy costs? Also possibly safer in certain scenarios like tornadoes etc.
Potential issues that immediately come to mind are ventilation, earthquakes, and flooding. But it’s not like underground dwellings/basements/etc. aren’t a thing, so maybe those issues have been addressed in ways I’m not familiar with.
My graveyard-shift friend simply gets sunlight before going to work later.
It’s cold down there. Have you ever gone into a basement? That heat is useful.
Have you ever spent time in one with other people? My basement (furnished hangout space) warms up pretty quick when I have guests.
What’s the point about your friend. Apparently they are still getting their sunlight every day.
Right, and likewise underground dwellers can still go up to the surface to get their sunlight to prevent the havoc that you warned of. That’s my point.
It’s cold because it has a large thermal mass and nothing heating it up.
Human civilization produces a lot of heat. The thermal mass means it might take years or decades to reach its heat equilibrium. But that equilibrium will be excruciatingly hot.
