Oxygen planner

Balance duplicant breathing, oxygen production and the resources your setup needs.

Active time is your planned operating time. Inputs must be supplied continuously while a building runs.

Geysers

Initial rates use midpoint rolls including dormancy. Enter the measured average for your geyser. Storage must bridge inactive periods.

Resource ledger

Per-cycle balances. Each material keeps its own unit; steam and liquid water remain separate until converted.

Water+0 produced · −600 consumed

Negative totals need an additional supply. This balance does not automatically throttle buildings or account for heat carried by materials.
