Electrolyzer, SPOM, O2, Oxygen: Tutorial nuggets : Oxygen not included

In this tutorial I try to cover the Electrolyzer, this is a rather large topic and I try to cover as much of it as I can without letting the video run to long. Their are several designs and variants of O2 production out their are I try and cover the ones that I think are the most useful.

Specifically, it’s 2 parts hydrogen, 1 parts oxygen, but hydrogen is 1 g/mol, while oxygen is 16 g/mol, so there’s 1 gram of hydrogen for every 8 grams of oxygen

[@nukeacitrus883]

Thank you for the guide! I just managed to get my first hydrogen powerplant running, following the second (?) version you showed. However, I initially got oxygen mixed in with the hydrogen during the first run, which broke the generator. I tried creating vacum by running the lower pumps, but the oxygen levels shot right back up to 2k oxygen pressure when it reached sub 500. After a while I figured I could pop a gas-filter between the gas tank and the gas generator to filter out the oxygen. Eventually got the oxygen out of the top segment! Wow, that was a lot of text to say: I had a problem but I figured it out, thanks for the guide!

[@LamontGranquist]

For the full rodriguez, the second power transformer is useful to pull off normal wire and run off to your sieve and pump. It also seems to be useful to throw a switch in between that transformer and the two electrolyzers allowing manually shutting down half the electrolyzers if you've accidentally way overbuilt your oxygen generation capacity.

Worts did not originally give off radiation. That was added March 2021 well after this video. Worts are still useful early game but you have to keep them out of the way.

[@MrSomebunny]

Forgive me, I’m new to the game. How do you combat eating through the maps water supply? Do geysers produce enough steam/water/ect. to keep up with demand for your base and this form of power generation?

[@FrancisJohnYT]

This is not about power production this is about O2 production. The Hydrogen is technically a waste product it just so happens you can use it to provide power to run all your O2 production. Also wate vents on average produce about 2kg/s of water though it varies. So 2 water sources on a map is usually enough to support a massive base.

[@MrSomebunny]

Francis John thanks! Love your videos, by the way. They’re cutting down on the learning curve immensely

[@fang_xianfu]

Just got my full Rodriguez up and running, thanks so much for this video!

[@FrancisJohnYT]

Bathe in the glory of so much O2, just make sure you don't run out of water or stifle your crops with heat.

[@S_Black]

@@FrancisJohnYT In sandbox I found that you can cool a full Rodriguez with an AETN if you pre-chill the water. According to the min/max-theorycrafting in the wiki you shouldn't do that because of heat creation or something. But as you did in the video you can cool the oxygen within the SPOM with the water. And then the AETN can cope with the rest. To me it seem that running an aquatuner now and then to chill down a cool steam vent during eruption is much better than running it full time to cool the oxygen. Going to to that in my current game since I have the AETN and vent right next to each other :) Though a 3/4 Rodriguez may be enough for me

[@BNJ_SOT]

0:14 the mass ratio is actually correct, I just realized this after thinking it was wrong like you did for a long time. It's a mass ratio not a molecular mass ratio. 1H2O -> 0.5O2 + 1H2, O2 mol mass is ~ 32 g/mol, H2 mol mass is roughly 2 g/mol, so you'd expect 16g O2 per 2 g H2, or 8:1. ONI gives 888:112, which is pretty close. Very interesting, love this game and your content man

[@FrancisJohnYT]

Yeah was only thinking in atoms not atomic weight. But you got to give it to ONI despite some of the interesting takes on physics :) they did include a fair bit of science accuracy.

[@vtmegrad98]

how exactly do would I load one of your save files? does it not work simply because it's too old, or is there something I'm doing wrong. The game auto-migrated it into the "PetBoilerTut1" folder, but it won't load

The saves are different between the base game and the DLC, this save was from the base game. You would need to revert to the base game to load it up.

Thanks, this design was so effective it overpressurized my entire base :p

[@moremer66]

You are the best! My bases keep improving because of your videos

[@dmitrykargin4060]

SPOM is even more complex. Different pump configurations can provide different H2/O2 ratios. Game mechanics for gas distribution sometimes transform some gas block to another gas type when gas block tries to move or expand. So there are cases when O2 block can turn H2.

[@FrancisJohnYT]

Check out this Klei thread on the topic, they may have patched this out though so I'm not sure how true it is anymore. forums.kleientertainment.com/forums/topic/100796-electrolyzer-and-pump-layouts/

[@SpottedHares]

The interesting thing is that if your willing to put in a bit more work on these designs, you can use your electrolyzer as a heat deletion system.While the oxygen will be hot and needs some work to get it from cooking your base, the Electrolyzer can match the steam turbine in terms of heat deletion. Though if using a Thermal Aquatuners is still required unless you just feeding it fresh made water from something that is very hot.Alternatively a AETN can be feed the surplus hydrogen for cooling instead.

[@FrancisJohnYT]

There are a few niche ways to delete heat, you can also use plant to eat a bit of heat. Someone made a great one using pills on conveyor rails. Turns out at the time fridges dropped the temp of things really fast so pass the pills though one and you could demolish huge amounts of heat that way. The steam turbine ended up winning due to also being a power producer at the same time.

[@evilmonkeyshineful]

I attach a water sieve and use polluted water in my system, I love a filthy Rodriguez!

[@AznDumbum]

I was wondering, what temperature range does the Full Rodriguez it requires to run effectively? Can it accept water as hot as 99?

[@FrancisJohnYT]

In theory yes, assuming you build it our of Gold amalgam so it does not overheat. Though I would cool down the resulting O2 before you send it to your base.

[@evilmonkeyshineful]

Thank you for the video, it was well informed and helpful. I have a question regarding the Full Rodriguez, has there been any recent updates to its design to make it more efficient or self-sufficient? Also, if I wanted to use it to use the device to destroy even more heat what could I modify to the existing design?

[@MrEMaan]

On the full Rodriguez, I keep getting Oxygen intermingled with the Hydrogen out of the top pump, which damages the generators. Sensor settings are correct (250g at top and 450g on bottom ones). My base is not using all the oxygen (overpressure at vents). Does this cause the problem? I built this with the hope that it would be more than I need, but could grow into it.

[@FrancisJohnYT]

When you first switch it on you have to run it flat out for a good 300-600 seconds. That way the gasses sort themselves out, if you don't run it flat out the gasses stay intermingled and it never runs quite clean. If you build a couple some gas tanks or high pressure vents you can run it flat out and get it working clean.

[@huhnocorn7397]

my personal favourite way to create oxygen in oni the video i saw was made by brothgar i used the idea (cause i hâte morbs and making them produce oxygen for me sounds great) i tweaked it and made it more compact and gave it a counting system (using the new “single digit counters”) (the counters are activated by the pressure plate that opens the door on the dropping mechanism) and a made it so it won’t activate at night (i put the out house spawners next to each other/side by side) so they won’t interfere with each other (i believe i got the timings synced but i’m not sure) i’m pretty sure that there’s 44 morbs currently

[@probablynotmyname8521]

I use cryptic foxs oxygen generator setup, very compact and east to create. In my current base im then running it through your aetn gas cooling setup.

[@FrancisJohnYT]

I seen his video on it, I'm pretty sure I modified his version to make the four tile high one.

[@shaqtaku]

I have a problem regarding the full rodriguez (11:55). Even with four electrolyzers running, I am not getting enough hydrogen to keep all four hydrogen generators running and keeping it all self powered. Also I noticed that one gas pump is not enough to completely fill the gas pipe with hydrogen. Do you reckon I should add another gas pump?

[@FrancisJohnYT]

They don't need the hydrogen gen to run all the time, you hook them up to the smart battery so you can control it. Once the battery is charged they turn off. If you just burn all the hydrogen immediately you will run out after a while. The save game file is linked in the description if you want to load up the map and have a look.

[@686Impulse686]

Great video. Used first version inside my base and it worked pretty good. Temps were not a major issue at all. I did find the second version with Wheezeworts does work. My o2 is being pumped out at under 20c and I am pumping in over 60c water into the system. I have pumped the room full of Hydrogen and use Temp Shift Plates, and that seems do do a great job. But like you say near the end. It is up to you if you want to cool the o2 or not.

[@FrancisJohnYT]

It takes about 100+ cycle for the temps to even out, try to remember to keep an eye on them if your running plants. Stifled crops have finished more than one base.

i built the exact same setup of the spom that is 4 blocks tall and has the 3 gas pumps and i have had i running for multiple cylces but oxygen still keeps getting sucked into the hydrogen line and damaging my generator. why is mine not working?

[@FrancisJohnYT]

The save game file is linked in the description if you what to have a look at it. But from the sounds of it you may not be running it flat out, you have to run it without letting the gas pipes back up for about half a cycle. This lets the hydrogen fill the top. You can either use high pressure gas vents or a couple of gas tanks to store the output.

[@totally_not_a_troll]

TBH, my favorite "SPOM" design is: 1) Go to frost biome 2) Make it there 3) have hydrolyzer in middle and one pump above, one pump below 4) pipe goes from the top, around the room to the bot and out 5) bot pump has 5-ish bridges INTO that pipe (this makes it add all it's gases to existing gasses of the same type already in the pype 6) a single gas filter at the end ___________________________ This consumes the least energy, is much less labor intensive, produces almost the maximum possible output, is not prone to faults of any kind. Later you have to do the cool water trick though, frost biomes do melt :P

[@FrancisJohnYT]

No argument here, that is super handy. But maybe keep a few of the designs on file, some of the new maps don't have cold biomes. Also some of them don't have gold amalgam. It's pretty rough.

[@hyperforce]

Really cool, I personally started running my base with 2 full Rodriguez generators, and I'm compressing the excess oxygen using a door compressor. But not matter which one I use I never get these things to run on themselves

[@FrancisJohnYT]

What else are you powering bar the electrolizers, gas pumps and liquid pump? Oh should point out I once used the same liquid pump to feed two electrolizers and this was to much power draw and ran the SPOM out of power.

[@hyperforce]

Its either an inconsistent water input, blocked oxygen output or power issue. Right now i guess its because i have 2 of these outputting to only 2 pipes for oxygen out. But its still producing more than i need so i didn't bother fixing them. Im more miffed that the hydrogen output is lower bc of it.

[@resugram_YT]

I think its time for this to be updated to fully incorporate power station in the set up. One thing to note here is that oxygen output now comes out at the same temperature as the water used.

[@FrancisJohnYT]

Last I checked O2 Comes out at a minimum of 70C but will be hotter if the input water is hotter than that.

[@stainedglassstories7735]

Hi! I love your guides so far, they've really helped me understand more of the mid-late game options where the game's built-in tutorials fall off. With all that said, I'm struggling to understand something about the full-Rodriguez design. With the half-Rodriguez, you're able to pull the full volume of gases generated by the electrolizers without causing a problem. So why doesn't anyone add a 7th pump in the bottom of the full-Rodriguez to get a full 3.5kg of o2 out? The only answer I can find on forums is that it makes keeping the pressures stable a more complex problem, but I'm having trouble seeing it.

[@andreashofmann4556]

Why does one of your designs (the one with the gas tank) with 2 electrolyzers work on 2 gas pumps (for oxygen) and the next design require 4?

[@FrancisJohnYT]

Every design is a compromise. 2 gas pumps does not take full advantage of electrolyzers output but you get exactly 1kg/s of O2 in a four tile high package. 4 gas pumps does take full advantage of the electrolyzers but depending on your base you may need to load balance the 1.75kgs output. Additionally takes more than 4 tiles high to fit it in. I included a scale of designs of players could pick something that matches their dupes count and play style. The joy of this game is the variety of play styles you can use and how all of them are the correct way to play.

[@braize6279]

Yeah that's the nice thing about these designs. I currently need the power more than the oxygen, so the "4 tile high" build will work perfect. The O2 will be enough for my extra dupes, and I can use the H2 for power in a build that is already a net positive in power. Which also works because my gas gyser is about to go dormant. Makes for a good stepping stone for when I'll need a more O2 heavy build

[@sebastianussembara3463]

after i build this spom my duplicant has debuf "Popped Eardrums", i read on wiki this debuf make by overpresure atmosphere, and now my oxygen has a mass of 6-7 kg -_- any suggestion?

[@James_McKay]

Turn off the generators and use the oxygen? Can even set up a atmo sensor to turn the electrolyzers off when the pressure reaches 2k or so.

[@FilAsians]

Great tutorial, as always. I have a question though: at 13:43, you hook a pump and a sieve up to your SPOM. Wouldn't the wires overload? Maybe I don't have a great understanding of transformers.

[@FrancisJohnYT]

The pump and sieve are on the draw side of a small transformer, the line can never draw more than one KW so it will never overload (Not 100% accurate there are ways to do it but it's rare) The system may chug very rarely when to much draws at once but it will run very safely.

[@FilAsians]

@@FrancisJohnYT thanks!

[@nefstead]

@@FrancisJohnYT I was wondering why you had a transformer on that model, which by default only uses 960 W. Makes more sense if you're attaching a pump and sieve!

[@turosianarcher8771]

I did some testing on Hydrogen/Oxygen volumes out of a Full Rodriguez vs an unfiltered setup consisting of mini-cells 6 wide by 2 high with an electrolyzer in the middle and pumps on either side. Image here: imgur.com/a/yal4FZd You can route the output of each pair of pumps through a filter of some sort, either powered or unpowered using gas bridges and gas valves using techniques I learned in Brothgar's video here kzbin.info/www/bejne/mKvapJqBlNeompI. The results running each setup for one cycle was that I got nearly identical quantities of Hydrogen and slightly less Oxygen using 3 electrolyzers and 6 pumps in a cell configuration as I did from a full Rodriguez. Full Rodriguez: 2160W, 13.97Kg H, 1639Kg O. 3 Cells: 1800W, 13.8Kg H, 1533Kg O. For my base's Oxygen needs, I am using a Full Rodriguez, but after these results, I'll be using 2-4 of my mini-cells in space for my rocketry program. Modular, easily expandable, and more efficient (for Hydrogen at least) than a Full Rodriguez.

[@IPUNTGNOM3S]

Does the third set up still work? Why do the electrolyzers not have a water intake?

[@n3rdy11]

Either the wiki and this tutorial are outdated or my game is bugged. My Electrolyzers are outputting air at pretty much exactly the input temperature of the water, which is 30 °C because I'm using po2 from slime biomes, cleaned trough the Water Sieve, which also doesn't heat/cool the water at all. Which is all super weird, I remember heat being such a big issue from playing during EA, so I a built a massive cooling system involving the anti entropy thermo-nullifier, which turns out to be complete overkill because instead of 70° hot air I get 30° warm air that my cooling setup cools to like -30 C° lol

[@FrancisJohnYT]

Give it a bit of time, all of the equipment in the SPOM have default temp when they are build of 20C-40C it will take dozens of cycles for the hot O2 to heat it all up to temp. Give it about 100 cycle and you will be glad you setup the nullifier.

[@n3rdy11]

@@FrancisJohnYT That's the usual heat up over time from the machinery emitting heat, but I'm talking about stuff like the water sieve always outputting at 40° and the electrolyzer at 70°.

For some reason, the temperature evens out with its surrounding extremely rapidly and, in a survival setting, it can seem like the output is not 70C at all. It is definitely not a fixed output temperature. It is input temp plus a little bit of heat generated by the electroyzer. Same way with the Water Sieve. It is strange that no one talks about this change and I can't find when this got patched. Even this youtuber doesn't know it changed.

[@S_Black]

One thing I found is that there are situations where you don't consume enough of the excess hydrogen. At the beginning that extra hydrogen can be your main power. But it eventually becomes a subnet that may see little use. I just had a situation where hydrogen started to appear in the oxygen line. Bad if you feed that line to atmo suit docks. Eventually the hydrogen should be put into the main power plant and the prioritized over natural gas. That way everything in the base can burn it off.

[@TheMule71]

In my experience, that is far more common. You should never let hydrogen back up. With a couple of bridges and a well placed element sensor, you can detect when the pipe is backing up and if you plug the sensor to the automation of the local generators, you can have them burn the extra hydrogen. Oxygen backing up is rarely a problem, if you set the pressure sensors correctly. The electrolyzers go overpressure and the production stops. You can remove the generators and dump extra oxygen into space (or feed it to those-nasty-slicksters-nobody-likes for food) if all you want is the hydrogen (for example, rockets, they consume equal parts of O and H, so either you keep petroleum engines around, or you have way to much oxygen) and you have external power.

[@francisdoherty5580]

@Francis John will the water pumping through the system at 14:20 do the reverse? If you are running 70°+ water, could you cool it down?

[@waylandsmith]

No. 70° is the minimum output temperature. If the input water is above that the output will be proportionally hotter too.

[@nacholibre4516]

A "Rodriguez" sounds like something you aquire from "a lady of a certain description"

[@Dagroth]

In a setup with 3 gas pumps and 2 electrolyzers (about 8:52), if each electrolyzer produces 888g/s of oxygen, and each gas pump only pumps 500g/s of oxygen, why doesn't it eventually overpressure, or pump oxygen into the hydrogen part of the room?

[@FrancisJohnYT]

Only one element can occupy a tile at a time. So at the extreme end of that if you have a two tile room with 10000kg of water in one tile and 1kg of O2 in the other tile the water cannot just crush the O2. In the build you list the electrolyzers do over pressure and stop working as the O2 pumps cannot pull out the O2 fast enough. But the hydrogen pump gets stopped by the Atmo sensor before it can pull out so much hydrogen that the O2 could replace it.

[@jonathany1240]

Is there a mod for pressure overlay? I’ve always found it a real pain to have to mouse over areas to determine high/low pressure and to predict fluid behaviour.

[@FrancisJohnYT]

You might want to check out "GasOverlay" it's a mod that gives each gas it's own color and the color intensity determines the pressure.

[@jonathany1240]

@@FrancisJohnYT This might be suitable for my gameplay but I'm surprised there's nothing made yet that displays pressures in a similar way as the base game does with temperatures. To me it's a reasonable necessity as pressure has been some of the failure causes of a lot of my bases.

[@KW42ON]

I really enjoy your videos. And i have a question... Can you make a Video about your experience of improving Game Performance? Like Tiling out, pathway optimization, if it is better to vent out gas into space rather then mass storage. The Abyssalite bug and some more really messed up my FPS and you seem like the one who knows how to handle that.

[@FrancisJohnYT]

Don't have to many tips to be honest, cutting down on dupe pathing helps a bit, collecting all the debris on the map and storing it in one spot makes a big difference. Restarting your compute ever few hours helps as well. Never load a game from inside a game. Exit the game first, don't just exit to menu exit the whole game and then load the game up again before you load up your map.

[@rocksummit3375]

I built my full Rodrigez horizontal because I had volcanoes on my top floor besides that everything is just the same. My problem is my smaller power transformer keeps running up to 127 degrees celsius and overheats. I have no idea where the heat is coming from, everything around it is at around 50-60 degrees. I'm not sure how to counter it either

[@rocksummit3375]

Ok, So I replaced it with a large power transformer. That seemed to do the trick, feels kind of bugy imo.

[@delorescummings8102]

how is the second SPOM self powered? with 3 pumps and 2 electrolyzers the total wattage comes out to 960, and the hydrogen generator only powers 800?

[@jonathanfine9780]

In the second model you build, what are the settings on the Atmo sensors?

[@brandon4801]

17:36

[@danielbri149]

Having trouble with the full Rod model my hydrogen is not pushing down enough and oxygen is getting into the generators? Something I am missing?

[@FrancisJohnYT]

You have to run it flat out until the gasses equalize. By flat out I mean all the O2 pumps should be pulling out O2 for a good minute without backing up. I usually hook up the outputs to gas tanks or high pressure gas vents to ensure this happens.

[@UltraXan]

Huh. So it seems the oxygen production solution that I've been using is the "Half Rodriguez". Been working well for me so far, but you've shown me a few modifications I can make that can help improve mine (Such as snaking water around the pumps to cool the oxygen). That and I think I may have misplaced my hydrogen pump since the amount of hydrogen it pumps is rather paltry... Not gonna be able to play until tomorrow night, but definitely something I need to look into. I'll also have to consider building a "Full Rodriguez" at some point!

[@FrancisJohnYT]

Save file is attached so have a look about and see how they are stuck together. Can also stress test them if you want.

[@sechi7239]

In the second model, how do you prevent the electrolyzer from shutting down intermittendly due to overpressure? I cannot get the system to be self-contained for that reason.

[@FrancisJohnYT]

The 4 tile high design? To get it to stabilize you need to run it flat out for a couple of minutes. By that I mean extracting Oxygen at maximum speed and not letting the line back up. Simplest method it to hook up the output to a gas tank.

[@MegaLars10]

Whats wrong with them shutting off? If you don't need more oxygen there's no problem with them shutting off. They'll start going again when the pressure is lower

[@FrancisJohnYT]

@@MegaLars10 Sorry about the delayed reply. Their is no problem with them shutting off after they have been running for a bit and the gasses have sorted them selves out with hydrogen on top.

[@348joey]

How is the design at 6:20 self-powered? It produces 800 from the generator, but two electrolyzers and three gas pumps use 960 total power.

[@ZeroXcuses]

I made the version with the gas tank, minus the doors in the interior because he said in the video that they don’t do anything except allow Dupes to get in and out (mine do not get trapped). The electrolyzers do not produce enough hydrogen, so the center gas pump pushes through an oxygen/hydrogen mix, damaging my hydrogen converter. So I have to add an air filter (taxing the power to over 1000 watts when it cuts on) to sort the hydrogen and oxygen, re-routing the oxygen back with the other two pumps. I even set the pressure gauges for 450, 450, and 750 like in the video. I’m out of algae, so had to whip this up or I would die. Still need to clear enough space/gather materials for my first attempt at a “Rodriguez,” but I’m already concerned that it might not work out given this trial.

[@ZeroXcuses]

Maybe I'll add the doors or play round with the atmo sensor, because my pump runs constantly even while set to 720.

[@FrancisJohnYT]

You have to run them flat out for about half a cycle for them to start running clean. So you can't let the O2 or hydrogen back up. Hook up gas tanks or high pressure gas vents if you have to so they do not stop running.

[@ZeroXcuses]

@@FrancisJohnYT Thanks! I'll keep an eye on it to see what I might need to tinker.

[@ZeroXcuses]

To follow up, yes, the doors were necessary to consolidate the hydrogen. I can now remove the gas filter. Watching your other tutorials!

[@lexguttman]

Is there a way to get the old saves working? I downloaded it but the game wont let me load it. Or do i need to rebuild them myself in sandbox?

[@moonstruckery]

Why do you have a power transformer there at the second setup?

[@MrTomyCJ]

The machines draw more power than a single cable can handle. If you don't use a transformer they will overload and break

[@Keldoh3ad]

Hi Francis, I've followed this video to a T yet when I build the full Rodriguez I'm still getting Oxygen into the vents, even if I flood the area with Hydrogen in debug mode.

[@noname-eo1he]

Have you added the Automation in correctly? I messed that up once in sandbox and it broke everything.

[@fritt_wastaken]

A better way to produce oxygen imo is by using deodorizers. It's a good use for p water, doesn't require cooling and produces a ton of clay for ceramics (especially good for maps that don't have a lot of it)

[@OpreanMircea]

before the update that added the topside I'd run out of filtration medium, I don't know the dynamics of resources now, especially when you can grind rock to sand

[@FrancisJohnYT]

Ah the old fill a 5 ton tank with polluted water and deconstruct it to get a 5 ton bottle of polluted water that of gasses like crazy. It's handy early on but it's not reliable long term. SPOM are set and forget you don't need to maintain them, as you get bigger stuff that does not require player input is the most valuable. Edit @Oprean Tirfan Mircea They added more sand and regolith falls from space, filtration medium is effectively infinite.

[@fritt_wastaken]

@@FrancisJohnYT You can just compress some liquid between airflow tiles, or just spill it out if you don't like compression. It only requies one delivery every once and a while. Sure it uses external power, but is a nice alternative to electrolyzers non the less. I supply 15 dupes with it right now and planning to go for ~25

[@coling.4476]

For some reason my Full Rodriguez is never returning a positive hydrgon amount, it is always trying to keep itself running which it does not succeed. It needs an external battery hooked to it to keep it running, followed everything step by step. Is something nerfed in the current game?

[@coling.4476]

Nevermind found it out, I crammed the bottom part together, no extra room above the electrolyzer. The main problem was that there were tiles directly under the gas pump, so it tried to pump while in vacuum or small amounts (mcg) of hydrogen, costing more energy than needed.

[@c0de99]

Probably not gonna get a reply on this old-ish vid but who knows :) How does one cool this oxygen? 70C is a lot (sorry if i missed a part where you explain this) Currently im using an aqua tuner/steam turbine to cool my PWater which i then recirculate around my base to cool things down (works like a charm) but i fear that by adding 70C or more in terms of oxygen might break things

[@FrancisJohnYT]

Check out the Temperature management tutorial it covers most of this. I can say that one Aquatuner running polluted water can handily cool 3kg/s of O2 with ease.

[@c0de99]

​@@FrancisJohnYT Oh ok, awesome! I have watched that tutorial as well after posting this last night. Thank you a lot for your work so far and your help! Ill start building your setup for 3kg/s of O2 asap :)

[@let4be]

Ha, you can even destroy shitton of heat by electrolizing near boiling water(which got heated by aquatuner) and use aquatuner to cool oxygen and your whole base. It can nuke about 250k dtu/s which is a lot and can even cover moderate industry. This is pre-plastic cooling which is especially great

[@let4be]

Another fun part is hot hydrogen - you can burn this in hydrogen generator, no need to cool it or anything like this. The only foreseeable problem is gas pumps overheat, so it gas may need immediate cooling right in the electrolyzer chamber(with radiant pipes from aquatuner) or you need gold amalgam/steel gas pump which might be problematic early game.

[@Spamhard]

So I built the one you show at 6:20, works perfectly! Although I'm finding one issue that I'm not sure if it's normal or not; pipes backing up. The oxygen I'm not too concerned about (I've got it distributing all along my base so if one vent is pressurised it'll move to the next, although even that's now backed up with more oxygen than I can use), but also I quickly found that not only did the hydrogen pipe back up, but also that the gas tank filled to full. Is this anything to be concerned about? I'm assuming not so much because it'll just run when there's space for it to run, right? Should I be setting up my smart battery to a specific setting? I've currently got it requesting at a pretty high number just to try and keep it constantly asking for more power to try and keep the hydrogen used. I do have a pump in the lower end of the map venting out CO2 to space so I'm hoping pressure will lower again but honestly I don't have a huge issue with a lack of oxygen as I only use 8 dups atm, I just wanted to switch to a SPOM now that I had comfortable water supply and before algae got dangerously low.

[@jakel.7947]

Hey Francis John! Long time watcher, first time commenter. First I would like to thank you for all your videos and tutorials. A game like "Oxygen Not Included" would have caused me so much headache without some guidance, so thank you for being there to clear things up when I needed it. Second, I was curious how would these designs react if water supply stopped for a while or the oxygen output pipes became over pressured? Early in the game I may use a single electrolyzer and that could potentially make more than enough oxygen to the point where my base would be over pressurized by it. Would this break the design or mess with how the built in filtering system works requiring me to flush the system again as if it were running for the first time (or do the atmo sensors prevent that)? Any clarification on this would be appreciated, Thank you!

[@Slenkamure]

i am guessing they have fixed the water to electrolizer issue where it takes in 10 units and uses it like 1unit. Also at what point does the SPOM MKII with the tank start to accumulate extra hydrogen. When i build the same thing it never does unless i turn off the generator

[@Spamhard]

Such a great vid, thanks a lot! I'm really wanting to step into electrolyzers as my algae is slowly depleting (tbf I could probably last another 100+ cycles or so on it), but I was reading so much about hot oxygen being an issue that I wasn't sure how to really approach it. Love the idea of running the water pipe through the oxygen first to help cool it, and also the ice biome idea. I've seen quite a few builds use an enclosed section of cool pwater to run the oxy through, but it confused me a little because wouldn't the water start to heat up from the hot oxy in the pipes and eventually not provide sufficient cooling? Or is that not an issue? I found a slush geyser recently, was going to use that to run through my hot water (I've been using a tepidizer to remove germs to give me a source of clean water to eventually pump into the electrolyzers), but maybe I could use the pwater from that somehow. I dunno. Oh, I also love how you show all the piping and wiring, and also say what your sensors are set at. It's amazing how few guides actually do that.

[@ddrweb_]

Nice video, thanks! Can you do one where you explain the different materials types when you construct something. Maybe it's my fault not understanding the dtu stuff :)

[@FrancisJohnYT]

Material types are more about overheat temp. Copper, iron and aluminum overheat at 75C. The O2 and hydrogen come out at 70C, throw in the heat the machines give off and you can get to 75C and damage the machines. Gold gives an overheat bonus of +50C so your equipment won't overheat until 125C so it's much safer. Steel gives a +200C bonus which is why it is so valued.

[@datman2433]

Heat capacity is how much energy it needs to change temperature. Thermal conductivity is how well the thermal energy (heat or cold) will pass through it. Imagine a water tank, HC is how much it can hold and TC is how much said "water tank" flows. If you want to insulate your base, high capacity with low conductivity. If you want different temperatures to come in contact fast, you need high conductivity.

[@williamr6385]

Not sure how old this is. But you can use smart batteries to control the hydrogen burn. You get lots of bonus power and extra hydrogen for other uses

[@matteocdt5214]

i plan to use 95°C water from geysers. should i integrate some form of cooling for the SPOM?

[@kingjames4886]

I like to build an extra electrolyzer, find it works better. theoretically one electrolyzer should be able to saturate 2 pumps so they're constantly pumping a full 5km unit of gas and not wasting power, so 2 electrolyzers should do 3 oxygen pumps at the bottom and a hydrogen pump at the top... however it's almost impossible to get the pumps to run 100% of the time just because of how gases more and merge so adding an extra electrolyzer allows them some downtime, they aren't using power while they're not working so it's not any less efficient and keeps everything nice and full of gas. 1 hydrogen pump, 4 oxygen pumps, and 3 electrolyzers seems like a good ratio for large-scale oxygen production. also having the electrolyzers up in the hydrogen layer will produce more hydrogen if I recall, due to how gases merge. you can usually just leave the bottom open if you build a vertical setup too, if it's set up right extra oxygen just flows out the bottom and you capture all the hydrogen. also for cooling if you have extra power you can put some thermo regulators up in the hydrogen layer and run the oxygen through them to dump the heat into the hydrogen then feed it into a generator to destroy it.

[@FrancisJohnYT]

I prefer the Rodriguez, 4 electrolyzersand 3kg/s of O2. I like a high dupe count and putting one of these down future proofs you for a long time to come.

[@ACkayla]

Can someone please help. The oxygen pipes below the electrolyzer from the two air pumps are not pumping air out into the pipes below. It is clogged with oxygen and I also have oxygen going up into the hydrogen generator too causing it to not work and the whole system to run out of power.

[@DjSharperimage]

Great video

[@BaterieCZ]

Not working on my map... Gases are mixing and moving into wrong pumps...

[@FrancisJohnYT]

You need to run them flat out at the start, as in hook up gas tanks or high pressure vents so they can work at full speed. After about half a cycle they will stabilize.

[@ohmiohwa4199]

5K soon so soon

[@FrancisJohnYT]

Close but not quite yet.

[@let4be]

Why nobody uses mixed SPOM with an open airflow bottom where part of oxygen diffuses out of the system naturally and the other part being removed by a single pump. You can save quite some power this way
