self-sustaining oxygen/energy from 2018 is not working

[voron43]

Hello, I'm playing in ONI for a week and I'm really tired of digging every time I'm out of coal/algae. I found some "self-sustainable" setups from 2018, but they aren't working. Well, at least those that I found i reproduced in sandbox, and they died in 3-4 cycles. I'm pretty sure that the thing is not about my "silly reproductions", they are not working because of fixes by developers for past 2 years. I saw they cut reproduction/generation of some machines.

I'm trying to create my own self-sustaining machine, but I'm in despair after so many tries. I've tried setups, but my reproductions are not working. I guess I need help.

I've just digged to oil and got steam geyser + copper volcano just near my base. I guess I need elecrolyzer setup for oxygen and some steam setup or something like this for making energy from geysers/volcanoes. Could someone link such setups, that are working now? If my reproduction of setup wouldn't work, well, than I would believe that problem is on my side.

If you've got another "self-sustaining" machines that works in 2020 I would be really happy to reproduce them.

The SPOM design that's floating around on the forum works just fine. My guess is that if you built it, you forgot to include a few key parts. Namely the smart battery hooked up to the hydrogen generator to regulate power production. Without this, your hydrogen generator will waste a ton of hydrogen by producing power when the battery is full.

How about posting some screenshots or save files with your setups in them?

We could help more if we knew what you were doing "wrong" (not that it's really wrong, but may no longer function as it used to

or it may have been using bugs/glitches/exploits that have been fixed).

Test simple old design self-sustaining oxygen genereator. Works fine, no problem.

Spoiler

This setup overproduced hydrogen, works fine with expensive gas filter, you can build very early, then after research logic and refined metal replace gas filter on gas shutoff and got more free hydrogen.

Attach save file for your test.

What this tricks? It's special design room

Spoiler

Here on the forum there was a topic with a detailed analysis of various rooms and counting the production of hydrogen and oxygen in them. This design showed maximum hydrogen production compared to other rooms.

Welcome back, first find a salt geyser and filter the salt water to water. It's really easier than convert steam to water in early game and it produces more water.

About electrolysers, make your choice here : https://imgur.com/a/aMUUkFr#dyigQ1p

Or you can use this one without filters (Francis John) :

Atmo sensor (top) : active if above 250

Amto sensor (bottom) : active if above 450

just wanted to point out 2 things (that you probably already know but could be unknown to others) first is that you can submerge the desalinator in the salt watter wich means you wil not dump heat outside the salt water chamber hence not needing a cooling room with wheezeworts. second is that if you have only 1 desalinator you have 2 problems: A) you will lose water production because the desalinator output is 5kg/s wich is not enough to keep up with some salt water geysers and since you already have the set up you might (or not) be intrested in maxing it out. B) you will stop producing water when the desalinator is full of salt so if you have the desalinator output pipe directly connected to the electrolizer you will stop producing oxygen, i assume you direct it to a water tank first creating a buffer of water to prevent that little water shortage problem but in my case a decided to have a backup desalinator set up so that when the automation system detects my 2 main desalinators are full of salt it activates the 2 auxiliary ones.

yes the size of this set up is quite considerable wich for some base setups could be a no go specially if the geyser is inside the base, but i have lots of free space in the map and i am not rly the minimalist type, i am also a bit obssessed with surrounding every heat source with vacuum so this could be adapted quite a bit.

the automation is quite simplistic, if the output pipe of the main 2 desalinators doesnt detect water it means they need emptying wich activates the 2 backups, once the main 2 are active again water will be detected and that will stop the backups, this will go on for as long as salt water is detected, if for any reason they stop working and salt water reach the top sensors it will isolate the geyser wich will stop droping water into the system.

this is a functional design wich i felt comfortable with, there was no minimal space considerations put into it, just a simple and symetrical output maxing set up

honestly i agree with you, is wuite a pain in the ass, wich is why i always try to find a Thermo-Nullifier asap to set up my electrolyzer oxygen production, once its set up properly you can just forget about it wich gives me great peace of mind and it actually fixes both problems since you get power out of the hydrogen production.

Appreciate your help guys, now it's working fine. My problem was about automation batteries I guess. I already built a huge farm of oxygen and going to deal with its temp and salt geyser.

Now I'm out from my small despair

Yea, but then you're heating up the salt water, which means that ( assuming you don't boil it -- it only needs to heat up 5 degrees! ) the fresh water coming out of the desalinator will be hotter and need more cooling.

The one time I have tried getting water from one of these I died a heat death.  Just couldn't keep the thing cool.  I did much better with a pwater vent instead.

wich is exactly why you use it for oxygen production, since the electrolizer is a net heat deleter

https://oxygennotincluded.gamepedia.com/Electrolyzer

"Heat economy

Consider cooling water as little as possible or even dump some heat into it before delivering into Electrolyzer. The input kilogram of water is more heat-dense than output kilogram of gasses, which is convenient, as it makes gasses easier to cool down afterwards.

But it gets better – 1 kg mix of oxygen and hydrogen at 70 °C carries as much heat as 1 kg of water at 19.45 °C, which means that with 19.75 °C input the electrolyzer starts destroying heat and becomes net heat negative. It will destroy 4.179 kDTU (1kg * the specific heat of water) per every degree above that, until reaching 70 °C where the outputs also begin to rise in temperature and the efficiency drops to around 3kDTUs/degree. With near-boiling 96 °C water it will stack up to 288 kDTU/s in absolute numbers, which is comparable to 3.6 AETNs."

ofc that doesnt mean you can just dump that oxygen straight to your base, you need to cool it a bit anyways, but not only is easier to cool a gas, its also cheaper since you destroyed part of the heat in the water by pumping it into the electrolyzer.

Of course.  The heat just coming out of the desalinator was the problem.  I guess if you can put it in the salt water and not boil it, then the electrolyzers will take care of the heat.

now that you mention it i have never boiled it even tho the system is perfectly isolated in vacuum and the desalinators have been running for 1000+ cycles, i guess its all sent and deleted in the electrolizer.
