Compact Oxygen Production - Stackable Electrolyzer Setup - ONI  

Blowing-up a Rodriguez with Reactors, I almost died laughing, great intro!

@@greezyhammer764 Thanks Man! I appreciate that! :D Nice to have you here! I thought if only there was something to get rid of the rodriquez..blessed be the DLC.

What does the polluted water do? Couldn't the airflow tile just be on the bottom?

That's how glowstick dupes are manufactured.

Understandable. :D They offer so much for less effort. Good that Oni offers a lot of methods for some challenges :)

How do you feel about melting rocket interiors?

@@kacperk3242 tbh also feels like cheating. They should just add larger rockets

​@@nousername8162 I wander how would you feel about 2 million kg per tile magma compressor.😅

​@@heyhoe168 Meh, if it's for lag reduction it kind of changes everything. But I guess it depends on the situation.

Nice :) Be sure not to build it on the far right side of your base. some weird bugs happen there since a few updates ago.

Hi Conor nice to hear. sad that the auto sorting did not work first try. I tested it around 50 times and only had 1 that went the wrong side. But since you are now the 2. Person that had it switched i may have to re-test that? Tip: In the lets play i added switches to the electrolyzer so you can change the output to your needs.

HeyGungeoneer! Nice to have you here. Well that depends on the day: The Design took me about 30 minutes. The day before I watched a francis John video and saw someone line up the Korean-Version of an electolyzer setup.I had a work break (different shifts just like the dupes) and went straight to my test world where i testet different placements of the tiles next to and above the electrolyzer first. That lead me to find that some placements randomize the outcome of the gasplacement/gas exhaust so some versions only place the hydrogen and oxygen correct once the room is already filled with the correct gases (i.e. they are not reliable when setting up). I want my build to be very hard to break and (not necessaryly easy but) reliable when setting up. So i checked different versions and wehen i found one that worked for 50 tests in a row i continued with the idea. As i said this design was quickly finished because the mechanic wasn't new. After the Oxygen Production I checked if i can be transformed into a SPOM - which was easy. But the SPOM could break because the hydrogen generators could overheat so i added the radiant pipes that fixxed the problem. Normally it would take a very long time to test that (everything in the rooms sucks up heat but eventually and be it in 1000 cycles they would break) but i know the output gases are at least 70°C so i pre warmed every room to 70°C with (9999kg of gas a couple of times) then made all rooms vacuums and tested the machinery. Thats how i noticed that the heat deletion from burning the hydrogen only is enough to cool the generators when some radiant pipes are used. So much for the design process. After that I test how to build it in a survival setting. Then I need to film the snippets. The hardship with that is finding the right sequenz to place the parts. That takes up around 2 hours depending on the build longer. With multiple versions and around 40-140 Snippets. Then I choose the music depending on the amounts of video snippets (more = faster beat). I mark the beat of the song and fit the snippets to it. Then If i still have time in the 1 minute timespan I try to come up with little skits that make the video better to watch. And maybe some bigger build for the end of the #short. The editing takes around 7 hours average. Seldom quicker like 4h once I had 17 hours (my other SPOM -by the way i put the editing time in the description). But that is mostly because i don't have enough excercise I guess? I make the thumbnail for the shorts in my video editing program. But for the shorts youtube picks a random second of your short and shows it. I even tried to put a picture there the youtube choose another part as a thumbnail.... For the Pc i just upload what i designed (mostly the first seconds) Then description, comment preparation, finally the upload, tags, and info cards. Hope that helped and thanks for the support.

XD I just tried it. Haha thanks for that.

Seems to be a common occurance now since a few updates ago. We have no clue why. THis affects a few hydras. Mainly on the secondary planets and on the sides. Sorrry to hear you have those same issues

@@Luma_plays I made it work by using 3 different materials, Petro, oil, and brine on top. I don't remember the kg amounts off the top of my head, but the machine is stable.

@@coryl8837 Glad you found a workaround! I will remember that solution for later :)

@@Luma_plays I love the design. Infinite gas storage, and auto gas filtering all in one. I have a hydrogen separator on the 02 gas piping before it hits the base. Just in case.

Sometimes the good old reload button need some pressin'.

Hey "Be Gone". You can use an improvised Version by running some radiant gas pipes through a cold liquid (build some tempshiftplates out of ice and they will become cold water. See improvised cooling in my Let's play ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4QDFBeDTwIs.html Or build a Version cooled by an aquatuner ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-L7R-LE_uG4w.html. Hope that helps :)

I feed my current one from a cool salt geyer. It's output is enough to support one electrolyzer (actually 1.5) by itself. Run the water behind my power spine first to cool them, then through the hydrogen area, then through the O2 area to get it up to about 60F, then through the desalinator (powered by the SPOM, which also provides lots of extra for the base) and back down to feed the electrolyzers.

It's cool

Hi Phan Nghia I like it too :D. This has the additional positive effect, that the infinite gas storage is included. The water is the reason the room can't overpressure, so you have the storage right there included. For cooling: you could cool the oxygen in the gaspipes to the left when they are in the wall. Change the wall for granite wall build the isolation further to the left and run the cold water through the granite wall or something like that; haven't checked that yet :)

Yes I sadly only learned that afterwards.

I prefer the hydra over the gas pressure controlled versions. I like my overproduction :D At the moment i build them horizontally not vertically. But sometimes the vertical version comes in handy.

Hello, Oxygen is output at a minimum of 75°C in every electrolyzer. If the oxygen is cooler than that, then the incoming water is cooling the oxygen - depending on the piping (as intended). You can cool the oxygen by piping it with radiant gas pipes through sone cold metal tiles. How you cool those tiles is up to you: -ice -a proper cooling loop (AT+ST Setup) -wheezeworts And and so on Hope that helps :)

@@Luma_plays ahhh that’s makes sense, thank you, I’ll set up a cooling system

In terms of Output or materials? If both have the same number of electrolyzer this produces more. That is because it will always put out the full gaspackages and never stop never getting overpressured. The rodriguez is stopping alot normally that is how it functions. In terms of simplicity and material the rodriguez wins easily i think. this here can be very annoying to setup. As many hydra setups. Both have their pros and cons and depending on what you want you can use them side by side.

Thanks! Did you place the tiles above and besides the electolyzer in the same way (also they need to be of the same type airflow etc as I've shown). I think in my testing in the past this special setup had a very low chance of the gases switching sides ( 1 in 100) when I tested. But it still happened once for me. You can reload before it started and try again to see if it does it again or separates correctly. You can also check out my longer Video "building the spom" where I show it in a real game. Hope it still works well for you :)

It appears everyone comes up with a design like this in their ONI lifetime. :) After I build this I found the system that greezy build 2 days before me. After that I found a korean guy that did it 2 years early. Every build slightly different but still similar. A viewer showed me the first electolyzer version that was submerged and i (month later) in a work break came up with the stacked spom design. But apparently it is called "The Hydra" and has been in the forums forever.

I know about @GreezyHammer I love his content too. Thanks for reminding me about the Hydra, that is shockingly amazing and from early 2017. monkaS

Hi Malerickk. An electrolyzer produces 880g of oxygen per second that is enough for 8.8 regular Dupes (every dupe uses 100g of oxygen per second). There are heavy breathers and divers lung duplicants that consume more ore less oxygen. But if you have 8 regular duplicants they normally use 800g. So 3x880g=2640g that's enough for 26.4 Duplicants. Problem here your Gas Pumps can only transport 500g per second and a pipe can only transport 1kg per second. So the solution 2640g/500g=5.28 that's how much Gas Pumps we would need. So I just used 5 Pumps. 5 Pumps can fill up 2 full 1kg per second pipes and one half filled 500g pipe. Hence the 25 Duplicants. I wouldn't cool this setup because you want to destroy the heat of the Hydrogen in the Hydrogen Generator Part. If you cool the oxygen inside of the Setup you are wasting a lot of energy. Better cool the oxygen when it is outside of the building. you can run radiant gaspipes(steel) through some cold liquids. I did that in one of the let's play episodes. Hope that helped

@@Luma_plays At the moment i'm using this setup (with a little adaptation because of cold plant nerf): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_WogK9JXWns.html&ab_channel=TheAngryBreakfastClub Making cold inside the building (for the Oxygen section) is what i have at the moment ahah ^^ Also, in your design here, i'm wondering something. In the setup i have, a single Hydrogen generator can deal with 3 gaz pump, electrolyser and one water pump, because everything is not used everytime. In your build, you have 3 hydrogen for 6 gaz pump and 3 electrolyser. Can't it be optimised ? 2 hydrogen generator wouldn't be enought ?

Hi @@Melerickk the enegy consumption can easily be explained or calculated: If you have a single hydrogen generator that produces 800w if run continuously and you have 1 electrolyzer at 120w that if run continuously only supplies 2 gas pumps at 240w each you are now at 600W. The 3. Gas pump is for the hydrogen supply and doesn't really run very often, same goes for the liquid pump at 240w but only 10% of the time. So you are at 1080W maximum strain only some of the time. But most of the time your average energy consumtion is below 800W more around 600W. I see where the confusion is coming from: In the video I couldn't show that you can also hook up the liquid pump to the grid because of the format. But I myself do so. The build has 3x 800W of max. power. That's 2400W: 3 electrolyzer running non stopp because of the infinite gas storage that is build in it. That's 360W. 5 gas pumps running non stop because it produces a little bit more than can be handled by all the gaspumps (considering you use up all the oxygen with 25 Duplicants). That's 1200W. Additionally 1 Gas pump running only some time + 1 Liquid Pump running 30% of the time. Thats. at least *72W* - 360W. We are at 1632W-1920W. So since the lower value is above 2x800 we cannot only use 2 Hydrogen generators. But if you put the liquid pump on another grid 2 generators could work for you.

@@Luma_plays Imma try this ^^ (i'm currently live on twitch xD trying to figure out and testing your thing ahah xD i already made the grid calculation to get it symetrical xD)

@@Melerickk Nice awesome to hear. I have 10 mins to chek in :D. Just uploading another vid. I sadly cannot comment i have no twitch account.

Hey mrblob: good explained. As for the size: With a few stacking exploits you can overlay most building but I personally don't like that. But theoretically you can make a single electrolyzer spom in a tiny room the size of a hydrogen generator.

@@Luma_plays Idk about overlaying any buildings, I'm not even sure how to do that. I just meant that if you are really conservative of your space there are ways to make this design even more compact if you are willing to prefill both sections with their respective gases, which really isn't too hard to do in a real game. And from the testing that I've done it works just as well and is not that hard. I just thought to comment as this would give you an even more compact variant for just a tiny bit of extra effort. I can try to send a screenshot of it on your discord for a more clear picture.

Ah no not necessary :) i was agreeing with you regarding the size. The player can always make this design smaller. There are alot -maybe not hundrets but many different- versions that are smaller. I choose this cause it was the first i figured out myself before learning that the community already knew of this. Called hydra and there are many designs. But of course you can share any of your designs in our screenshot discord. that is always appreciated.

@@Luma_plays Ah, ok. Would love to see you show your design or showcase a design that is more compact. Anyways, thanks for the chat!

it is not "just" to force the gases out but also to prevent the electrolyzer itself from overpressuring. both from liquids or gases. meaning it will never stop producing gas even when it normally would stop. Hence the 2 liquids. to compensate for both goals. displacing gas and preventing overpressure. using only 1 liquid in masses would overpressure the electrolyzer

@@Luma_plays trying to wrap my head around that. So, the pressure of (2000 off the top of my head, but that could be the vent) is determined per substance, and then it takes the larger number, not the total?

@@sneezyfido That is a good question. The answer is probably:whatever klei programmed per building. It doesn't have to be a hard rule. but for this one it is probably: liquid and gas overpressure is measured seperately. And there is also the tile of operation and the tile of measurement. both are often the same but not necessarily. but take that with a grain of salt. I am no specialist in the inner workings of the game. i only use or exploit them :D

@@Luma_plays exploitation leads to understanding 😁

Yeah, I just wasted several hours to learn the flipped version doesn't work as well...

Hey Coalrock Where use the airflow tile?

@@Luma_plays to tiles right above electrolyser. leave no gap and oxygen will still go left and hydrogen will go inside air tiles.

Hi Eternal Hermit. Yes this is directional. But if you pre fill your chambers (fill a little hydrogen left and oxygen right) and then start up the system then that works too. In this build the block placement around the electolyzer decides of something gets atop sorted or if there is a random chance where something goes. so if you place a full block or a airflow block in a different spot or orientation changes the behavior of the gases there.

That was me blowing up a Rodriguez design XD. In case you wonder: in the DLC there is an atomic reactor or whatever it is called there. If you overheat it... well

Hi Kaine. To filter itself automatically and the same way reliably when you set it up: there cannot be a tile over the electeolyzer even an airflowtile. And there has to be only one airflowtile to the left on the shown height. As far a my quick testing went this should work (most) of the time. If you would place some airflowtiles on top it would only work 50-50 sometimes it would sort hydrogen to the left and oxygen to the right sometimes the other way around. Other combinations even let them mix if the rooms aren't pre filled.

I and a few other people having problems recently too with that (that = the liquid moving). See below Any two liquids where one of them is heavier / denster than the other and the top liquid should not off-gas. And you don't have to make it 2kg i learned that now. You can also just use full bottles with 200kg. The liquids should never be pushed around: that is an issue that seems to occur since the last update. I fixed it in my base by making the right wall of the electrolyzer airflowtiles too. BUT: sometimes it is a location problem.We just found out on the discord server that: sometimes the electrolyzer setup (as seen) only has problems on the rightmost side od the base. We think it might be ghost data of geysers or something. So my tip try building it more central or to the left or build the right walls of the electrolizer (where the liquid touches) out of airflow tiles) still make sure the gases are correct.

A electrolyzer in liquid (a small liquid amount that doesn not trigger the submerged state) will keep on working without any pauses. A normal electrolyzer will stopp as soon as the controll tile is over a certain pressure. This normally is gas pressure around 2kg per tile. Since we permanently filled those tiles with less than 2kg per tile. it never gets the informstion "stopp producing you are overpressured". hence we get an non stop producing electrolyzer. The relevant tile here is in the second row counting from the bottom. so the first (the lower) liquid layer can have a high amount of liquid (as long as you don't submerge the electrolyzer) the top liquid layer has to have a tiny amount of liquid. (less than 2kg per tile but more than 0.07kg per tile as far as i remember)

I had that happen once. You probably were in the gram area where the liquid can be displaced. Can't remember the exact mass though. i think if both water packages (polluted or brine or salt water) and the fresh water on top are around 1 to maximum (below) 2kg it should be fine. If you want to see how i did it in the let's play: look for "building the SPOM" episode 6 or so. Hope that helps. I know it is hard to manually drop the correct amount thats why there are other methods that can achieve that.

At least some of the time, it's like unstable

Maybe it cant be less than 50g of liquid at a time

I have noticed that behaviour too. Weird thing is that on the main planet it works for me. On the second or third planet it buggs out sometimes. Especially when on the right side of planet. When build on the left side it is fine. You can also try 200 kg of liquids (200kg Saltwater and then 200kg of clean Water) instead of 2kg that *can* make it more stable. I still don't get why it behaves weirdly since a few Updates ago.

The one that is destroyed by the nuclear reactor is a rodriguez setup. The one you see after that is this setup but for hundrets of dupes.

@@Luma_plays Yeah you're right you're right

Was that what you expected to hear? :)

@@Luma_plays I myself personally was just wondering why one would build an electrolyzer setup inside a nuclear reactor. Then I realize that there were captions explaining the situation 🕵️

@@coryl8837 Ah i used that for the joke because everyone normally uses the rodriguez :D

really love your vids btw unique ideas that I wouldn't have come up with

yes, most hydras are self cooled. Through the non stop production amd the incoming water. In combination with burning off the hydrogen the excess heat is desteoyed anyways. Still "cool" is around 75°C so you may want to cool your oxygen further down when using in an living area :D

@@Luma_plays thank you

those systems cool themselves. the water input gets added a certain amount and then output as hydrogen and oxygen. which both have differen heat capacities than water. baaically deleting heatenergy in the process. if you build the electrolyzer out of gold amalgam giving them 125°C heat/overheat resistance then you would have to really do something weird for this not to work. You also don't need to cool the hydrogen generators since you can cool them with the hydrogen itself then burn it away. (also gold amalgam). this is a version of the hydra setups that existed since around 2017 or 2019 i guess. so nothing out of the ordinary. Edit: your oxygen will of course be around 75°C since that is the minimum output temperature for an electrolyzer if i recall correctly. That is why most electrolyzer setups have a gas pipe cooling area next to it

They will! The rodriguez will be a relic then.

It is not. Just a different setup. Rodriguez is pressure based and almost never runs at the full possible output. This always runs at maximum Oxygen and hydrogen output because it cannot overpressure. Different approaches.

Yes that is a hydra. I thought i discovered something when build this but it has been known for a long time. Figures

If you use radiant liquid pipes from a good material the incoming liquid water should cool the hydrogen and oxygen. With cooling i mean to 75°C. So you still need good material for the electrolyzers and then cool the oxygen etc. But you don't need to worry about it overheating.

We found out that a lot of hydra designs have this issue on planets that are not the main planet and when you build it far to the sides (to me it was far to the right). When i build it in the middle or middle left it was fine again (on the same planet I had the hydrogen physics bug happening). This seems to be the physics engine bugging out at the borders o some planets for whatever reason, but we are not sure (we = the discord)

@@Luma_plays I built it in the middle of the main asteroid =/ The water gets pushed to the side and the oxygen leaks in.

@@TheBlackBeltPanda that's weird. would you mind to share that in the discord so we can take a look what might be the issue?

@@Luma_plays I was able to fix it by using just under 200kg of liquid per tile and replacing the tiles to the right of the liquid with airflow tiles.

you get 2 bottles :D nothing fancy just send 2 dupes or have them walk twice

@@Luma_plays Sorry I still don't understand. I mean I have water in a "lake" and how do I get out of it 400 kg of water?

@@andraskis6890 You place a pitcher pump in it. Sounds like you are fairly new to the game :). I wish you lots of fun with the game.

@@Luma_plays Thank you :)

But it does compact

I agree and disagree :D On the main planet it should work fine and very reliably. On other planets the liquid physics can bug out and that leads to alot of hydras beeing unreliably (not just this one). Not sure why. If we find out then i make a vid.

Hey KOP. The and-gate and the or-gate have a different visual. (I don't know which one at the moment. But if you compare with the game open you can see it). In the newer videos i write it on the top. The older videos are missing that feature. Also it seems that hydra setups on other planets than the first (and on the right side) can be buggy. so be aware of that.

@@Luma_plays I managed to get the design right. My only problem now is my cool steam vent is at the right side of the map and my main base is on the left side and I don't know how to organize the vent linings.

@@Luma_plays This is really important. I'll be stopping from playing until I fix this. All the electrolyzer has 2k polluted water each and having the wrong element doesn't affect it. I don't know if the polluted water has an effect in one of my containers. This other one has 945g water and it works fine. This other one has 33.8g the middle electrolyzer both have

Nevermind. I repeated the youtube short and saw what I did wrong. I should really watch it at 0.75 speed next time :)

@@kop7125 You use the hot water from the cool steam vent tamer for the electrolyzers? If yes good that is very energy efficient deleting heat. You will probably need insulated pipes (even igneousrock insulated pipes should be ok) to get the water to where you want it. Then try to cool the output oxygen from the setup.

Hi poohTV. I am sorry i don't understand. If you mean: How to cool the Oxygen with water? You could run the gas pipes (radiant) through a cold liquid. If you mean: How to cool the water on top of the electrolyzers? Don't. Thats not effective. Maybe you could elaborate your question :)

Don't let the game discourage you, embrace the mayham and the disasters :D It can be fun to fail a few colonies to see what happens. I played 5 colonies obly to cycle 35 just to understand the early game better. You can easily get to cycle 50 sometimes 100 just by building a single oxygen diffuser, a battery and a hamster wheel. Don't take in too many dupes, the 3 starter dupes are fine. let them dig here and there to find some roots and use the time to slowly explore the game. :) hope you have fun

I also have long form content :) If you mean the short video player, you can try 00:00 (this will open the normal video player)

That is great :)

Hey Man I did not delete the comment. Why would I take the time to answer and let other people see what you think and then do that. I am sorry but i don't know why it is not there. But you are right the comment is gone. Don't know why. I also just seen that another one of your comments got stuck in "held for review" because of inappropriate words (that wasn't true but youtube couldn figure out what :| | | | | | |:] means. Also every link automatically gets blocked until i review it because of potential scammer links. thats why those messages don't appear for me until one or two days later. But it seems like you are set on you opinion about me. So i can't help that. But I wan't you to know that I (if i actually see them) appreciate all comments even if critical as long as they are constructive. And i have never removed a comment except those (here is a link to a scammer site) ones. Sometime youtube doesn't show me comments but that is not the norm. Edit: I removed direct link to other channel, but you erased my comment -> I put a lot of thought into my own answer to your comment with links and so on. So i also would like to know why that is gone. Did you press edit on your comment or do it any other way just curious Edit edit: Just for the sake of completeness: А. И. wrote a comment under my SPOM - Let's play video that stated that I "stole" a design from a russian youtuber that was 4 years old. Then posted a link to that video (which was the case the comment was halted in the first place because links can be against community guidelines and require manual control sometimes) I then answered with: I came up with the design myself but it always is possible that other people have the same idea. Then linked to convergence theory. I also pointed out that the linked video clearly wasn't the original author since i could find an older source. Which i linked. After that I pointed out that i don't have the time and skilles to watch years old videos in russian or other languages. Then I wrote that i will remove the comment *IF* the link to a clearly false source is not removed, because i am not supporting free and false advertisement. After that I get this very message. What happened inbetween i don't know. Maybe you got reported (but not by me), maybe the editing went wrong maybe you deleted your comment yourself accidentally. And I (just like you) don't see the initial comment anymore. So I don't know why all that hate is necessary.

Care to elaborate?

What is a turbina?
