Spirulina iirc is nutrient rich, but you still need calories - something a spoonful of algae isn't chock full of.

Not to mention you presumably also want to diversify your diet in other ways - waters a good idea for both aquatic plants and fish, potentially.

But this post wasn't about that. We literally do not have materials strong enough to easily dome a community this large. One of the biggest can hold like 55k people - not homes, not space for growing food, or businesses, storage, or any of the other minutia of a society, literally sitting space for bodies.

Underground and several story buildings can help magnify the usefulness of the space again, but it's still pretty impractical. It's a nice idea, it could potentially make for new city opportunities in desert or otherwise less than habitable areas, but there's not a good reason to do it, we can't do it very well, or to the degree you=e talking about, with current tech. - and even if we did force the issue, they still wouldn't be self sufficient in all ways.

You wouldn't use domes. Either many underground bunkers connected by tunnels with logistics transport, or many sealed surface buildings. Depending how hostile the surface is. Domes don't provide radiation or blast protection.

So, we'll all be mole people? Given the amount of land I already talked about, trying to put that all underground makes even less sense.

A small enclosed area propped up by the buildings themselves, would potentially make sense, you'd still be able to get sunlight for energy and growing food, it's just not that practical to do that for like a few dozen square miles. But it's a hell of a lot more practical than essentially doing exactly that but also digging out a few dozen square miles of underground territory...

As for blocking blasts - why. Radiation could be as simple as water, tbh. It's what we use in nuclear reactors NOW. Iirc a 30 foot deep pool with nuclear shit at the bottom, you'd be safe from the radiation on the surface.

You get the energy from surface solar panels.

Yeeeeah, my mistake responding to you basically at all. I'm sorry.
