Can you live off of oxygen created from plants

[Anonymous No.16124822]

How much air do plants produce and how much do humans need, how big are the differences between plants on air production. How many plats of what kind would a person need to not suffocate in a sealed shut room?
Also how doe they not run out of air on airplanes, submarines, fallout shelters or space stations?

oxygen is plant shit
imagine breathing shit

I believe you can't do it realistically, but maybe for a while with a big enough "room". Plants also need to consume oxygen depending on the conditions and time of day, since they ultimately metabolise glucose to get energy. Their relationship with different gases (O2, CO2 and H2O primarily) is pretty complicated. On the space station they reclaim a lot of their water and split it into oxygen and hydrogen. This requires lots of electrical energy but I believe the space station can harvest solar energy quite efficiently. There's lots of room for solar panels in space, the light is brighter, and nothing much fucks the panels up unlike on earth where they get dirty. This could also be done in a fallout shelter or submarine with nuclear power, but without that it would require solar or oil which would be a lot more difficult (logistically). Aeroplanes usually use air from outside the cabin. It has plenty of oxygen, it just needs to be pressurised. They can also carry pressurised oxygen.

Yes, but you would need a lot of them. Imagine living on a vegan diet and growing as much food as you eat eat day. That's how much mass you would need to grow to create enough breathable air for the system.

>airplanes
Air from outside

>submarines
They surface to exchange old air with new air

>fallout shelters
They have vents, usually with traps and filters to keep out radioactive particles

>or space stations?
They scrub the air of carbon dioxide and periodically exchange canisters of gasses with supply shuttles

Jesus Christ, its a few google searches and you can't even manage that. Fucking retard. I found the answers in less than 2 minutes but I'm not sharing because you are a dumb lazy arsefuck. Do your own homework assignment.

and water is rusted hydrogen...

if you have plants in the room you sleep in, part of their mass has been part of yours at some point (the carbon).

Thats not true i have been looking for an answer for a long time and i am starting to think that maybe noone researched how much air exactly a plant produces and how much a human needs

I remember I tried to calculate how much lye (I think it was) I'd need to scrub all carbon I daily exhale and it was a lot, not feasible. you might need a small greenhouse or something, and should also depend on plant and plant age. they take more carbon when growing up than after it stops growing.

Thanks, how does the scrubbing of CO2 work?

[Anonymous No.16125209]

>>16125202
lithium hydroxide should be one of the best, I think that's what they use(d?) in space. chemical reaction with CO2 makes something + water and I think they hydrolyze the water to release the oxygen

There are chemical and mechanical scrubbers that basically remove the CO2 and store it for later disposal. The oxygen level slowly drops until you exchange your CO2 for oxygen. You should look into it if you're interested.

Obviously yes, but it's not very practical way of making oxygen from human perspective. You breath out about 1kg of co2 a day a tree absorbs about 25kg a year so you need something like 15 trees in a closed space with you to keep the air fresh (or equivalent amount of other greenery). The anecdote about being able to grow your own food is fairly accurate in that regard. In a fully closed cycle where the excess oxygen produced by the plant growing the parts you don't eat gets consumed by those parts decaying so that can't be counted. If you are only interested in the air for a short duration then you can cheat a little
A crop field of say corn may produce something like 2500 calories per square meter so you need a 365 of those to keep the air fresh

>You breath out about 1kg of co2 a day
out of which about 300g are the carbon itself. this is by the way how you can lose extra weight and why cardio works.
