How feasible would it be to live underground... permanently?

Share engineering protips on how to build a feasible underground colony (or at least a large underground dwelling).

About as feasible as it is to live above ground, permanently.

>> No.3165617

As long as you have a way to get vitamin D without sunlight, and some way to grow crops, it's certainly possible.

>> No.3165619

How deep underground? By "permanently," do you mean that you never, ever see the sun again?

>> No.3165624

it's easy peazy to build said colony. The price would be a factor, as would the lack of sunlight.

>> No.3165644

you'll become white from lack of sunlight
also vitamin D deficient

>> No.3165658

no, as side from the lack of vitamin D issue. It is a proven medical fact that people who spend long periods of time under ground will have high chance of stroke and other health problems.

How would you survive without a whole bottom of the foodchain? I'm assuming you can't use the sun, nuclear winter, some pop sci armegeddon event ect.

>squared ceilings underground
Wat. Unless you are building into solid bedrock, this is just asking for trouble. Arched ceilings are better for load-bearing and prevention of collapse unless the thing is made entirely out of concrete.

I think he's just hurr-durring a joke in saying that Canada doesn't get sun.

Maybe they put square ceilings IN the arches. For aesthetics.

UV lights or some sort of outside simulation with fake windows and displays.

Also fresh air.

Lack of Vitamin A and constant darkness and artificial light plus claustrophobia and no variation in your surroundings will make you suicidal.

Hello Artyom! You need some weapons? Okay, let's take a look.

Here's your submachine gun, some ammo, a gas mask and first aid kits, just in case.

In summary, very feasible. You need a source of energy. You need enough animals/seeds to start a stable breeding system/food plant. You can use a UVB lamp to get vitamin D/feed the plants. So long as you can use the dirt around you, you should be able to get the nutrients you need for the plants. You could probably match the CO2 output of the population with the O2 output of the plants, given enough space to plant. You'd be fine, but all this requires a source of energy.

Engineering problems are the easy part - build in good, solid rock, fairly far away from frequent fault lines (or make it quake-proof and avoid the "epic" ones that haven't gone off in thousands of years), and use arches, plus optional steel supports, to reinforce your structure. Side note; don't build too big.

That said, ecology is the hardest part, as mentioned above. You could have an electric-powered/solar lamp dependant ecosystem, using geothermal power, a solar station on the surface, or even a hydroelectric setup on a cave river. A nutrient source for your crops is also essential.

Psychological issues? Connection to a major cave to give breathing room/scenery would help. If it's generational, your kids will adapt fairly quickly, but recreational amenities (maybe some D&D or /tg/ material since, let's face it, you can't spare power for vidya) and the presence of a community would go a long way towards keeping everyone level. Communities can get contentious in isolation, however.
