Dewar of liquid oxygen
The oxidiser of every rocket fuel: an empty dewar filled at the gas plant with oxygen, or with the air itself.
In the game
How to get it
Gas plant, choice Liquid oxygen: an empty dewar and 64 units of oxygen, or the air where there is air (on Earth), 20 s, 8 kW. On the Moon, Moon ice gives a dewar of LOX and one of LH2 together.
What it is for
Poured into a rocket or a ship with its fuel: every engine needs it.
Why it exists
There is no air up there to burn with: a rocket carries its own.
The same text the game shows in its progress tree and on the item's sheet (I).
How to get it
- Gas plant, Liquid oxygen: an empty dewar + 64 units of oxygen, or the air (on Earth: nothing else needed), 20 s, 8 kW.
- On the Moon: 32 voxels of Moon ice + 2 empty dewars → a dewar of LOX and a dewar of liquid hydrogen, 30 s.
What it is for
The oxidiser of every fuel: methane, RP-1 or hydrogen.
