Hello there /sci/,

I don't browse this board a lot, and I'm not really the brightest one out there,

but I have a question.

Underground plants, what's needed for their growth, and could they be grown around 500-700 meters underground?

I'm attempting to design a nuclear bunker, and the only thing that still puzzles me are the food sources for a longer time.

Now that we have vegetables secured,
We'll need some meat, we need as much as variety in food as we can get, to keep the inhabitants happy, so we don't have any rebellions 500 meters underground.

How could one possibly secure meat and dairy products underground?

The only meat that would be possible would be fish, they can be grown in tanks and can be grown underground.

Help, please.

Plants need lighting and air and nutrients.
Lighting is the hardest part. You'd either need a skylight, generators (which require stored gas/coal), or geothermal energy.
Air is easy; that's what the people are for.
Nutrients is also easy; just fertilize them with your waste and practice crop rotation.

Meat is hard, but you could keep chickens well enough. They don't require much space or food. On the whole, however, you'd be better off looking at healthy diets for vegetarians and just using those plants.

>> No.1667846

Traditional agriculture doesn't work underground, so think about something else. Guinea pigs are supposedly delicious, they're small and breed quick so you can keep stocks down temporarily. They also eat cellulose, so you can feed them just about anything

>> No.1667841

>>1667827

That is obvious, and sorry, thinking about my previous arguments why that didn't sound as easy as it is, they are kind of stupid.

Still, back to vegetables.

Geothermal power would be an ideal, Wikipedia's diagram says geothermal power plants usually take the energy at depths of 600 meters, the bunker would be at that depth. (Ideal for protection agains't nuclear bunker busters)

Although, can geothermal energy provide enough power for a whole bunker?

Looking at it, this wouldn't be a relatively small bunker, it'd have a kitchen, living quarters, zoo, arboretum, storage rooms, etcetra.

There's no practical limit to the amount of energy you can get to geothermal. You just need to make your collection area larger.

Also, you shouldn't be using too much energy in this bunker of yours. Lighting for the plants and people, but not much else.

In such an environment the best form of protein would be insects. Damn near an inexhaustible food source. Insects can also help solve world hunger, then again, if everyone went vegetarian, there would be no food shortages. (Which I say as I eat my burger)

>> No.1667893

rabbits are pretty easy, though you would need alot of plants both as food and as air filtration. Geothermal power is your best bet because 700 ft down will have plenty especially if the drill a well even further down from that. You could probably get your water from a deep aquifer because no matter what happens on the surface it is not likely to get contaminated. My town uses water that is more than 20000 years old because that is how long it takes for water to percolate down. Anyway, fish, rabbits, mice, chickens, and minx (for both meat and pretty fur blankets.

On the other hand a healthy vegetarian diet need a lot of variety that can't be found in local products only. This means that they will need food that was produced somewhere else and was transported to them instead of eating a bug raised nearby.

Also, for humans, bugs protein isn't as good as biger animals protein.

Studies have shown people of different cultural/ethnic backgrounds digest virtually all forms of food differently and absorb astoundingly varied amounts of the various nutrients required. I recall reading several papers on this matter and could go further in to detail. although I fear I may misrepresent the facts rather shit-tastically. Gimme a sec to look for the papers. Very interesting shit, indeed.

Air bursts are mean but they sure don't last for longer than a few minutes of radiation and an EMP wave. 50 feet under ground is good enough unless he plans on surviving a direct nuke drop right on top of him.

Also OP, if you're going to build and underground bunker, find a way to make a lot of space for yourself count. Also, if you're going to have cattle, you can use the shit for methane powered generators. Remember, for all the things one could possibly need, from food to soap, a person needs 5 acres distributed for it each.

You can make soap from animal fat and acorn tops. Use chickens a lot. Have a good set of cows with a floor dedicated to them in a space of about 10-15 per acre you give them, which will be more than enough shit to power a 40 story office building if air conditioning isn't the biggest priority. Those things shit a lot man. Give 3 acres to plant growth. The last one should be spend towards pigs, housing, and a work shop. Pigs don't need much room.

look up Aquaponics, a method of combining raising fish in tanks with hydroponics, the waste from the fish fertilize the plants, letting you grow both is a tighter space.

Algae is a good source of food as well with many of the nutrients and vitamins people need and it doesn't require much to grow, the biggest problem would ofcourse be to set-up a place to grow the stuff in sufficient amounts. Some mushrooms however would be easier to do, nice source of nutrition and a good chance to recycle some waste material without much equipment.

And if all else fails, you'll always have a healthy supply of fresh humans.

Pretending i'm in charge of the whole project...

I do pretty much everything with aquaponics (growing fish and plants together, the plants are fertilised by nutrients from fish poo and the plants filter the water to be clean enough for the fishes.) So i produce the vegetables and some more expensive variety of fish in one farm.

Then to grow grains- people want bread, rice etc- i have a larger aquaponic farm with common table fish like trout or something would work well, and my grains.

then for my animals, another farm with common eating fish, and grass or whatever for livestock to eat. And so the animals eat the grass, and everyone has lots of decent food.

Oh and i also grow chickens by feeding them insects i allow to breed in the fish water.

But you can let them eat the parts of the plants that humans don't want to eat.

>>1669856
The problem is not for it being unnaturan, the problem is that it is expensive! You need growt hormones to keep animal tissue living and that is expensive! You also need a lot of antibiotics because you have a piece of living meat without a immune system. And you also need purified nutrients. Living animals evolved for billions of years to be efficient. The only reason to use in vitro meat is because you think it is better because it has no nervous system and therefore doesn't feel pain.

It probably takes less space to just buy the food and store it, than trying to grow it. Canned food + multivitamins should be enough.
Unless you are planning for hundreds of years which is pretty unreasonable.

It takes 1 hectare land to grow 5000kg rice, you can harvest 3 times a year if the conditions are ideal. With a 2m high roof it takes 20000m3 space to grow 15000kg rice a year. Storing that takes up around 17m3 space. By this calculation it would take more then 1000 years before its economical to grow your food rather than store it.
