Oxygen Not Included.

I have favorite moments in my ONI runs. One of them is when I finally turn on the base cooling. The habitation area is the ~60w x ~50h area that is mostly insulated into a block.

My cooling rig is off to the left.

In the pipe shot, same view, but that long ph2o line is full of 24c water. The base, including farms and stables, is a cool 25c throughout.

This is the moment where I really begin to push heavily into midgame.

It's c128, current census 12, target 16.

An Oxygen Not Included Screenshot: Same view as before, this time of temperature. The cooling system has been running for about 10 cycles, and the interior of the base is mostly in the green zone, meaning under 30c temperature.

An Oxygen Not Included Screenshot: Same shot as before, but this time the piping view. An enormous pipeline is snaked through virtually every interior floor or wall in the main base.

An Oxygen Not Included Screenshot. This is main-base shot. There are 10 floors of 4 cells height, and two columns of ~34 (left) and ~25 (right) width. A big apparatus lies off to the left, we'll go in to that in a second.

A closeup of that beast on the left. What we're looking at here is a) massive o2 and h2 production, and b) o2 cooling, and c) the base cooling, all in one. This is my go-to build for this triple purpose. Tho I certainly didn't invent any of this, I've never actually seen this variant from other sources.

At the center is the o2/h2 production. It is a submerged 3-electrolyzer version. The column to the right is an h2 infinistore, to the left an o2 infinistore.

Note that this is massive overkill. The o2/h2 rig is "always-on", meaning it runs continuously regardless of demand (as long as h2o & power are supplied. Every tile in the o2 column to the left has 385kg of o2 in it!

Why?

1) Because this way I can make the h2o supply intermittent and not worry about whether I have enough o2, cuz I've stored so much.

2) Because it enables *4* fully-loaded gas pipe outlets, which makes distribution easier.

Now, the exiting o2 goes through that big pool of h2o above it, using gas radiant pipes. (Aluminum ore is best for this in midgame, but in this case I used some wolframite.)

The h2o came from the cool h2o we start with, which I carefully gathered and protected very early on in the game. Later in midgame, we'll run out of it, and we'll trickle in some hot water, that cuz it's in such small quantity, won't overstrain the system.

One can use the thing as is for about 50 cycles w/no external cooling, cuz the mass of the starting h2o so overwhelms the mass of the o2 going through it.

But all good things come to an end.

Sooner or later, the starting biome starts to heat. And sooner or later, that wildly hot o2 exiting from the Hernandez-variant o2 prod starts to heat the water up too much.

The cooling rig is a bog-standard aquatuner + steam turbine rig, tho, again, there's a couple of variations here.

1) The ph2o coolant sits in two reservoirs down below. I have learned that precisely loading a loop of this size is a sucker's game, cuz I inevitably wind up changing the loop a little and having to do pipe work.

2) It first snakes through the h2o pool in radiant liquid pipes, before it runs through the entire base in ordinary granite pipes.

All of this adds up to tons of o2 at 25c, tons of water at 25c, and an entire base at 25c, and it's all buildable as soon as you get 1200kgs of steel. (And you can, as I say, use the thing w/o the cooling for ~50 cycles.)

I've seen rigs that come close to this before, but they mostly focus on cooling the o2, which is far less than what an AT can do. This rig is cooling the o2, the h2o, and the entire main base.

The submerged electrolyzers aren't technically submerged. Each of the three little squares has 200kg of salt water on the bottom, and 200kg of h2o on the top. The electrolyzer doesn't think it's submerged. But blocking those four tiles forces it to deposit its output o2/h2o to left or right. It will add the new material to any tile that has the old material, and has to be primed so that the one side starts with only o2, and the other side starts with only h2.
