Creating oxygen with polluted oxygen from slime, worth it or not, or it is exploit?
Hi there,

I am new to this game and loving it. I have seen a fair bit of tutorials about making oxygen from the polutted oxgen that were emitted from PH2o or polluted dirt.

I tried to test it out but the outcome seem to be not rapid enough. I found slime giving out Ph2o at the fastest rate, 41.7/s however it does appear to be on and off periodically which means the total will probably be less if you really do the math per cycle. I also found that the mass of the slime doesn't affect the rate of the Po2 that was emitting. Not like the Ph2o, the more mass it is, the more it generate but it never as much and fequent as the slime. I had an idea coming up a system where I can speard the slime ball on each tile while having the same number of deodorizers above them each. However to physically do this requires so much manually assigning and moving each slime ball into many single storage compactor and release them at the end. Plus it is hard when I have a mushroom farm and alge distiller running in the game which already require a lot of micro mangement in digging out slime and store them in chlorine room then make them avaliabile for delivery.

My question is, has anyone tried this and wouldn't mind sharing their experiences. I would be interested to see some designs as to how to optimise it or maybe its simply just not worth it as some think that's an exploit which I agreed to a degree as the germ in the polluted stuff should contaminate all kind of gas and stuff logically, not creating just one gas neither nor it should be oxygen that is polluted. Anyway, I plan to try this in a debug mode to find out in the future but just thought I could ask here to see if any advanced ONI lover would mind sharing.

Thanks in advance for the wisdom that you share.

ah i have played around with puft/morb farms algae distillers then deoxidizers its just easier and cheaper late game to run electrolizers sure its nice to have but not exacly advisable to have thats the problem

Kinda pointless, you can turn slime into an equal mass of PH20 and Algae. Algae can be turned into more or less oxygen per gram, depending on which method you use. PH20 can be turned into regular water, which can be turned into oxygen, if you really need to rely on slime.

You can use Slime or PH20 for no-power oxygen generation, but really, the ammount of effort it takes compared to an electolyzer (which can power itself) makes it a silly prospect.

Though if you want to try it for the novelty, logic gates and auto-sweepers can be used to automatically drop items, by deactivating them while they're trying to move items. Limit the storage capacity of the dummy container it's supposed to fail to deposite to, and you can continuously drop slime in separate packets to be off-gassed. Make sure the dropped slime is out of the auto-sweepers range, and duplicants as well.

Yes I agree to a degree. I just thought cooling down the clean water from the water sieve does require a fair bit of work and power or all other method of boiling the water to steam does require heaps of power and cooling. While theorically, I was thinking to do this idea in a space with good temperature and all I need are a atom senser to control the pumb (maybe a filter if needed) and sand. then just set it and leave it to dream about having infintite oxygen, given that I have infinite sand, which I know we do, and the polluted bubbles keep coming up. right?

Well, I think you should definitely do it as a supplement. Takes almost no time to build a bleach room to disinfect the slime. And since it still produces PO2, you might as well stick a deodorizer above the containers of slime.

I just did an experiment in a sandbox mode. I found the followings:

1) Althoough the mass of the slime doesn't affect the rate of it emitting Po2, it did reduce its mass by 125g nearly per second (literally after each time it emitted the Po2). So that means I will have to keep filling it back up.
2) The slime stop emitting when it hitted the pressure at about 1600-1700g per tile. That's how you can store them in the chlorine room without loosing its mass I guess (which I just found out)

Realising the slime was burning just like alge then I compared to what an Alge Deoxydizer can do.

Alge Deoxydizer
550g alge + 120w and added temperture -> 500g oxygen/s

This experiment
125g slime + approx. 66g sand -> approx. 41.7g oxygen/s

Also I did it with a sealed room with a wheeseword to cool the oxygen as the slime are usually warm at around 30+ degree C.

It doesn't look like it is effective after all. This then inspire me to try it on polluted dirt and I wonder if it is the same. Also PH2o would be a better choice as it certainly doesn't reduce its mass as it emitting Po2. However I know the emitting rate of it is very very slow.

There is a quote button... no need to copy-past

Anyway, you dont need to cool water from the water sieve if its going into an elecrolyzer, both are fixed output. You do want to cool the oxygen afterwords, but this can be cooled with 3 wheezeworts. Sure it takes work to set up, but compared to constantly refilling slime deposits? Not really. Its also a net power gain.
