Oxygen Not Included Builds

[Kipa Crawn]

Hiall, I'm new to oni and would love to see everyone's ideas and builds, ill start here is my SPOM and o2 Cooling build, the o2 comes out about 57c and passes through the cooling system to bring it down to 21c the cooling system is powered from my main supply.

Cooling medium here is 800kg of crude oil. There are two temperature sensors. Top one is below 130 C and bottom one is above 140 C.

Additional void between refinery and steam chamber is insulator (vacuum) and gives crude oil enough space in cooling loop to do not interfere with incoming hot crude oil.

only just started the game so i cant miss any thing but I don't like that the dupes ai isn't perfect and there pathing can get messed up sometimes but that's it really maybe more ways for dcor and activities would be nice too

Could somebody share savefile with this SPOMs solutions? I want to check efficiency of it. I never build something like that, I just set electrolyzers in my base, add 2 gas pumps on the top of colony to collect hydrogen (for all colony), and 2 gas pumps near atmo-suits docking stations which is connected to gas filter. By crude calculation, SPOM is more energy efficient, because for 2 electrolyzes you have 5 gas pumps, and in my setup for 2 electrolyzers I have like 5 gas pumps and 2 gas filters. BUT. In my setup all oxygen inside of gas pumps going to atmo suits, and rest of it going for base, and it is more then enough for survival. In SPOM solution you need to dump oxygen into base with pipes, and in that case it become in 2 times less efficient. And this efficiency should fall down if they idle because of gas pressure.

On picture you can see 4 metal refinery. They work in pairs, oil going inside of 2 of them, and then hot oil going to next 2 of them. After it oil with temperature 180-250C going through all this room, making average temperature around 150. After it oil going inside of 2 oil refinaries, where it become petroleum and natural gas (gas is located in separate chambers), and then petroleum going to oil generators (natural gas going to gas generators). Oil and natural gas generators emit polluted water. Environment is hot enough (150C) and polluted water transform into nice hot steam, which is consumed by top steam turbines. Molten slicksters like that temperature and CO from generators and produce additional petroleum.

Problems - if you have too much slicksters, they will eat all CO (as it happen on picture). If you will process all ore on map, room become too cold, bunt in this time you can build crude oil-petroleum converter which is based on magma, and get rid of petroleum refineries.

with SPOM you have 1 electrolyzer + 2 gas pumps for 10 atmo suits and nothing else. If you are using additional 2 gas pumps and 1 electrolyzer for spreading oxygen in base, it mean you are wasting 480 energy just to make "only-oxygen" environment.

As long as you don't have dupes with diver's lungs / mouth breather trait, one dupe will consume 100g/s. One electrolyzer will provide 888g oxygen (and 112g hydrogen) per second, which is enough for max. 8 dupes. Ergo an 1 electrolyzer setup can maybe provide oxygen for 9-10 atmo suits, but never for 9-10 dupes.

The number of pumps within a SPOM depends on the produced amount of oxygen/hydrogen, respectively the number of elektrolyzers. If you produce (more than) enough, your electrolyzer will regularly overpressure and become idle. Therefore and because a SPOM is basically self-sufficient, it actually can't waste energy.

I have 2 electrolyzers, and I'm using 3 gas pumps + 2 filters to supply 16 atmo suits. In barely-breathing area I have 700 mg of oxygen per tile. If we will go little right, we can see one more electrolyzer:

So, on provided screenshots you can see 3 electrolyzers, 4 pumps and 3 gas filters (could be 2, because of 2 pumps for 1 filter). They supply 20 atmo suits, and make large area "breathable". To achieve same effect, as I understand, you need 3 additional gas pumps? it's 720 energy wasted for nothing. (PS, right gas pump work 23% of time during last 5 loops)

I am never using spoms for my base (this is fourth base with over 1000 cycles on it.). Currently I am using one electrolyser for 8 dupes. Free hydrogen is captured at the top of my base for the purpose of LH2 generation.

Automation is tripple redundancy gas element sensor with separate filter gates plus one pressure sensor near the pump itself. Settings are per base design: If the flow of gases is easy You can set higher pressure limit. Hydrogen generator is a backup source of energy but it was not used since a long time.

Oxygen itself is cooled by one wheezwort few tiles above electrolyser.

Ok, here is another simple design for rocket heat recovery system:

Metal tiles, tempshift plates inside steam chamber, radiant pipes are made of gold. Three tempshift plates above steam chamber are made of aluminium. In this design steam turbine chamber is filled with hydrogen but it could be 25kg of petroleum. Working medium in radiant pipe is crude oil and this loop is just to uniform temperature. Insulated tiles and pipes are made of ceramic. There is slightly above 300kg of steam in each tile. Steam chamber is surrounded by vacuum.

Steam turbine cooling loop is using similar setup to this with crude oil - it is a closed loop with one bridge to force flow direction and is flowing between cool slush geyser and steam turbine chamber. However - cooling steam turbine chamber may be done in may other ways. Steam turbine is connected with heavy watt wire to the main high voltage grid.

Hello Everyone! I decided to create this thread to try and pool any and all builds onto one topic, @Neotuck, @Lifegrow (Sorry for anyone else I forgot to mention) have both posted a lot of useful builds on these forums which help new and old player alike, but as time goes on they get lost, become outdated etc. This thread can also help new players get ideas and inspiration, help veteran players power up to new tiers and just help people in general.

You can post any build you like and a short or long description of how it works and what it does, and what major patch it last worked on (If it contains an exploit of any kind please let people know as this means it might be patched out one day. NO ARGUING ABOUT WHAT IS AND IS NOT A EXPLOIT), whether it be an oxygen set up, an improved SPOM or even your critter ranch, If it's something you are proud of and want others to see or want help improving it, drop a post!

All I ask is that everyone please be considerate of each other, No Flaming etc and please accept constructive criticism. Sometimes an extra pair of eyes can point out something you have missed or they have had a similar experience and want to help you before it is too late!

Tonight when I am home (About 30 mins from now) I will post my Cool Steam Geyser Cooling System, Natural Gas Geyser Collection and Hydrogen Gas Geyser Collection (Just in case someone looks and sees that nothing is here! Also if anyone could find the post or recreate the post for mechanical filters I think that would be great to have here as well.

Once this system is ready I leave it running and it will pump gas to my base as and when it is available, Does not require any maintenance once it is up and running unless you somehow melt the Generator.

The automation inside with the geyser makes sure that the pressure doesn't drop too low as this will raise the temperature risking the pump overheating, the temperature sensor is also there just in-case the room is too hot even if the pressure is right. It isn't mandatory but I prefer it. The Natural Gas is fed to my bases storage which is starting to back up. The Liquid pump is set so that if there is any liquid on the top Hydro Sensor the pump will activate and sent any water to my base for processing, All Co2 is also planned to be processed in my base to feed slicksters.

This is a replica of my Natural Gas Geyser System, It follow the same concept, but it is a bit more temper mental, Sometimes the pump might overheat until the pressure picks up, once it does as long as the pressure does not dip below 2k it should keep up with the heat from the geyser.

Also can be used as storage too. All the hatches in the main room are stuck on the two floating mechanical doors. This speeds up grooming and also lets me open the doors to drop any eggs. Any living critters (except bagged ones) can stand on an open mechanical door and not fall, but the debris and eggs will fall into the room below. The clock sensors open the four main mechanical doors two times a cycle, one at night (long) and one midday (very short). Eggs naturally incubate in the room below until they hatch and become babies, when they become adults the autowrangling will kick in and a dupe will pick them up and send them to a room to drown. Then my dupes get some nice BBQ.

First is my bathroom plumbing, yes it is that important, and make sure ALL PIPES ARE ABYSSALITE, or you will cook your crops to death, and then starve. Ceramic is a good substitute at first if you are slow on digging, but you still want abyssalite ASAP. With this setup, the bathroom will not need more than 100kg water to start(10 pipe sections), and then it will produce polluted water for you to use as you want, and the way I use it is to feed my electrolyzers, which is why I have my Pwater tank set up to pump back into my bathroom plumbing to pass by the sieve again when my electrolyzer feed pipe is empty. This build also showcases the uses of pipe input/output priority.
