Manual crank type ventilation fan. Squirrel cage type. Thick HEPA filters. We did not have enough cooling air. Breathing air OK. The beginning temperature inside was about 58F. After 72 hours it was 88F. One hundred percent humidity. Not enough cooling ventilation.
I was giving out heavy tranks towards the end. We wanted to kill each other. We made it but barely. Clothed at the beginning. Naked at the end. Coed. Our bodies were the least of our concerns. My failed feeble point here is that until you have done it ... do not comment.

Then clearly they had not properly tested their shelter before that. That´s essentially a planning and engineering issue, not some impossibly unsolvable problem.
The norm here was to use the surrounding stone as heatsinks, combined with selfregulating evaporationbased cooling, no need for rivers. When you have a hundred cubic meters of rock per person to drop the heat in, it´s just a matter of engineering.
As far as the mega super deep maximum disaster civilization ending military and civilian bunkers existing is anybodies guess.
Not really.
Cheyenne Mountain in SE CO USA still works. One mile in, one mile down. Solid granite. Do others exist? Anybody got any inside info? Fracking misinformation?
Sweden has a couple of places like that, but not for squirreling away a handful of selfproclaimed VIPs, for the simple reason that it doesn´t really work.
Like i wrote before, anything that requires many years of shelter is so extremely bad already that it doesn´t really matter if you survive the first 10 years or not, because your NATURAL lifespan will be over before there´s anything remotely resembling a nation or society again.
The idea of stashing away a post apocalypse "seed population" has been looked at by many countries, and essentially been dumped, because it´s just not realistic.
