Oxygen Generator

Keeps you alive off-world by turning grid power into Oxygen gas — and pressurising the air around it.

Overview#

Every Nerospace dimension is airless — exposed players lose oxygen and suffocate. The Oxygen Generator is an electrolysis machine: it consumes energy from the pipe network and produces Oxygen gas into an internal tank. That tank both feeds the breathable field around the machine and can be piped out through Universal Pipes (gas layer) into Gas Tanks or other rooms.

N = Nerosteel Ingot · G = Glass · R = Redstone · C = Rocket Fuel Canister

How it works#

• Power in: connect a Universal Pipe carrying energy (from a Combustion/Passive Generator or a

  Battery). The machine stores up to 50,000 FE and accepts up to 1,000 FE/t. It cannot burn fuel directly — it is grid-only.

• Oxygen out: while powered it makes 4 mB of Oxygen per tick at 20 FE per mB (80 FE/t

  while producing) into an 8,000 mB internal tank. Pipes connected to it can carry the gas away (cyan stream).

• Oxygen field: while the tank holds gas the machine is an oxygen source, slowly draining

  (2 mB/t) to keep the air up. Air spreads outward through connected open space:

  • Sealed room (walls/roof — full blocks and glass are airtight): the whole room fills and

    stays breathable.

  • Open / leaky space: only a bubble around the generator pressurises (the air escapes toward any

    opening), so seal your base for full coverage. A door or gap counts as a leak.

  • Coverage reaches up to 16 blocks of connected air from the generator. In open space the bubble has a radius of about 14 blocks. These values are fixed.

• Loss: if the tank runs dry or the machine is broken, the oxygen **evaporates over about 10

  seconds**.

• Redstone off switch: a redstone signal next to the generator turns it off, and its air bubble

  collapses.

• HUD: a cyan O₂ bar appears above the hotbar in airless dimensions (it turns red when low).

• Airlock: a player wearing a full Oxygen Suit within 4 blocks

  refills the suit's air directly from the machine's tank, draining the gas — handy at a base door even when the room itself isn't breathable yet.

• Automation: emits a comparator signal from its oxygen tank level.

Tips#

Build an airtight room, run a power line to a generator inside it, and the room stays breathable as long as the grid is up. Pipe surplus oxygen into a Gas Tank as a buffer for power outages. A full Oxygen Suit is the portable alternative for exploring away from a generator.
