Maybe they have like an underground greenhouse with artificial light and irrigation
That was my next thought, but then where do they get their power, water, and oxygen?
I suppose it could be like a “reserve the surface room for a day” kind of thing, and hundreds of people live down below, with enough space for greenhouses and algea pools for oxygen production. Geothermal power, or simply a solar farm out of view, and deep underground natural water reservoirs…
I still think the immortal people in an indestructible house is probably the best bet.
So the look of this is similar to Silo 18 from wool and in that case they straight up used fossil fuels. The top bit was just for their exit and the cameras.
