Empty dewar
A padded steel flask of 1 m³ for cryogenic liquids: filled, poured into a rocket, filled again.
In the game
How to get it
At the grid: 4 steel plates, padding (wool, feathers or fur) and epoxy: 4 empty dewars.
What it is for
Every propellant: the gas plant fills them with liquid oxygen, methane or hydrogen, the refinery with RP-1; rockets and ships give them back empty.
Why it exists
Cold liquids need a cold flask, and a reusable one: the dewar loop is the logistics of space.
The same text the game shows in its progress tree and on the item's sheet (I).
How to make it
4 steel plates (the sides of the two rows), 2 padding (top middle), epoxy (bottom middle): 4 empty dewars.
The loop
Gas plant or refinery → full dewar → rocket screen, fueling tower or ship → an empty dewar comes back → again. Empty dewars stack by 64.
A vacuum-insulated steel flask of 1 m³: the liquefier and the hydrotreater fill it, a rocket gives it back.
