the gas generator in an ostensibly air-tight bunker isn't such a hot idea

[–] innermeerkat@jlai.lu 44 points 1 week ago (2 children)

Are bunkers really air-tight ? Don’t they pump air through filters?

[–] roguetrick@lemmy.world 5 points 6 days ago

Yeah it only gets to be a problem when you have to change the filters. Otherwise any apocalypse that involves a significant loss of atmospheric oxygen or major change in composition ain't something you can wait out, you gotta evolve past that.

Unless they have a self circulating system

[–] SanctimoniousApe@lemmings.world 23 points 1 week ago (2 children)

Which would presumably include a filtration system that cleaned the air of bad stuff.

[–] Diplomjodler3@lemmy.world 2 points 6 days ago (2 children)

Even if you somehow managed to scrub out the CO2, you'd still run out of oxygen pretty quickly.

[–] Delta_V@lemmy.world 3 points 6 days ago

Simple, get a miniature nuclear reactor to power the recycling of CO2 into O2 and C. You can then electrolize H2O to get more O and combine the H2 with the C from earlier to make gas for the generator.

Okay, it's just a setup like the Martian then.

Having a filtration system doesn't mean it's a good idea to create more pollution. In the same way that having a washing machine doesn't mean it's a good idea to start deficating in your pants.

When i dump the detergent in i also dump a cupful of dirt in there too, just to make the machine work harder. That way the clothes come out cleaner.

And you're telling me this now?

Yeah, could have used that knowledge a couple hours ago..
