Thx, I guess anime was an instinct.
The solution was:
Oxygen supply -
cryogenic (open)
chlorate candles (open)
water electrolysis (closed)
co2 removal -
lithium hydroxide (open)
metal oxide (closed)
rapid amine (closed)
Hey, first post here.
So I have to classify these 6 elements under closed-loop/open-loop system and under CO2 removal/oxygen supply.
I thought it should be:
Closed-loop CO2 removal: Rapid cycling anime, Lithium granules
Closed-loop oxygen supply: Water electrolysis, Cryogenic tanks
Open-loop CO2...
