this gave me oxygen not including vibes: in ONI its the same thing with CO2: in the beginning it is waste but in the end its quite valuable and you are desperate to get more of the stuff and curse yourself for dumping it in the beginning. this is great game design, this is what makes those kind of games so great AND boring to watch if pros play it, who do everything right. this is why I love watching you play games that are kind of new to you. its not what you do right, its the learning that draws me back to your stuff.

[@JPMistic]

what we do, is make 1 room pipe network, and add/remove what we need from that room network, with a back pressure reg to keep it at the right pressure. so in stat of a premix getting pushed in to the room, only the gass thats missing gets added, we also have a filter that pulls out O2 from the greenhouse when it gets above 60%

[@UnderFlow86]

I most of the time have up to 4 active vents in my rooms (Oxygen, Nitrogen, Carbon Dioxide and OverPressure) - I have a script matching the minimum ratios I want to have in the room, the Over pressure vent will be activated if I'm over the pressure I want to have in the room due to the "minimum" ratio rules, so e.g in the greenhouse the co2 will be still pumped in even if I e.h reach the 90kPa I mostly use as a default, and the OP vent will remove excess. I know I could simply use an atmospherics to remove the excess oxygen etc, but the logic is quiet simple, only costs a "bit" of steel for the pipes.

[@JuraHaw]

Problem is you dump your cold gas in hot tank and then wait to cool it again - that is your problem. I know you wanted do only one hot filtration, but cold filtration would help. Solution: 1) filtration of O2, CO2 and N from living quoters (temperature about 25°C), rest dump in hot tank in case of air contamination 2) Gas cooling - whatever technique you want 3) Safety when contamination happen - bypass cold filtration when temperature above 50°C (maybe less)

[@Rikard_Nilsson]

1:02:00 They changed the one-ways so that they have built in shut-off valves but they didn't modify already built ones so as not to mess with peoples systems, it was in the patch notes for...I think the last patch. Also you need to pump out oxygen because as it is the volume is "filled" (by your set max pressure) and it won't make room for new gas via some black hole magic where gases just vanishes so there's no circulation - no more co2 can enter and the ferns will just keep converting co2 to oxygen so the co2 level can only really drop. Also because of the oneway the two rooms (pipes) can't equalize either and because it's a premade mix you get only a fraction of everything you pump in.

[@Flipsie]

No, the room isn't 'filled' because I've got a pressure differential between the in and out.

[@vault1515]

I watched to 1:30 hour mark and in my experience I can say that most reliable is to have separate line of CO2 with pump and ic10 chip that will pump CO2 to a certain value. I have that setup with pump activating when CO2 lvl drops to 1.5% and stopping when it reaches 2%. Gas sensor is in the middle of the room so when it wil equalize the CO2 lvl is about 1.8 - 1.9%

[@kelemvour]

The RBLF takes great pleasure in watching the Splitsie faff about trying to fix bugs in his own systems. Silly silly Splitsie 😂😂😂😂😂

[@Pystro]

On the topic of those storm tanks: Were you planning to dump your heat into them, or were you planning to take the gas out of them, and dump the heat into gas that you then immediately vent to athmosphere? The former seems to make more sense. A: You're dumping the heat into a larger volume, so its temperature _should_ raise slower. And B: The logic condition for exchanging the gas with atmosphere is simply: "While athmo is cooler than tanks, exchange." And that one condition will work for both filling during storms, _and_ as a "bypass" when you exhaust the buffering capability of the tanks between storms.

[@Pystro]

To comment on your plans for next week: I would like to see the upper row of phase change cooling built before the setup with the storm tanks. If you want to see if the heat exchangers make a difference (other viewers might KNOW if they will, but I'm now curious to see it for myself), then you'll probably want to get them set up before the two cooling loops get way out of whack and take more than one stream to reach a steady state.

[@ColinRichardson]

2:38:00 the mushrooms are the new "you have a broken pipe outside the airlock"

[@Flipsie]

100%

[@tylerzerbe6861]

seems to me if you need more co2 the answer might be chocks. nobody runs chocks because they are difficult to balance, but you're splitsie, you're always finding ways of adding challenge to the games you play. (if you cant tell, i really want to see someone figure out the chicken mechanic in the game. panic and die had it sort of halfway ironed out but it was hilarious to watch him deal with it. at one point there was like a thousand chocks clogging up his whole base and he had to chase them all out the airlock.....then there were chickens running around the moon for a while after that because apparently the chicken mechanic lets them survive in a vacuum for a while)

[@Flipsie]

That's awfully tempting...

[@shadowdrake082]

Aww i left stream to early but here is some nuggets for helping. @3:27:00 the atmospherics is where things get screwy here. If the condenser and evaporator chambers are combined parallel like that, you only need 1 counterflow. The big problem though is the way the game handles the atmospherics, 1 device of each side will always take in the available liquids or gases leaving none for the other. You would need to fill the system with enough coolant so that both can work, but this is kind of a problem for the pipes if the temperatures swing too wildly. What i have done to limit how much coolant i need is leave the condensation chambers tied how you have them. But do not tie the liquid network lines together before the evaporation chambers. Have the two counterflows so that each handles a gas and liquid line for each evaporation chamber you use. This will prevent the game from pushing liquids only to a single evaporation chamber and will have both of them work together. The condensation chamber’s are fine to split up who has all the gas. Since you are cooling, all you need to have is just condensation, if both are condensing water, that just shows your system is working hard to dump off all that heat. Additionally you can continue to fine tune the phase change system by making sure the liquid pipes are pressurized higher than your condensation chamber’s setting (if possible). This will prevent any liquids generated by the chamber from evaporating so that all of it reaches either evaporation chamber. I think the bottleneck is the last phase change loop of water has a hard time reaching down to 20C, that may need more evaporation chambers since water has a hard time being a good phase change coolant when the needed pressure

[@PiroteusGaming]

Don't forgett to remind people that AC is also phase change just on a smaller scale and in this game withouth a specific coolant.

[@Maeyanie]

3:51:23: H.265, AV1, and _possibly_ VP8/VP9 (I'm seeing some stuff which says it does but not everywhere) support alpha-channel transparency, which are a bit newer/better than QuickTime. I have no idea what OBS support for transparency in those is like, however, I've never tried it... and given your current card doesn't hardware decode those, it might be as slow as green-screen anyhow. Might be worth a shot, though, the files should be a _lot_ smaller... even a good animated .gif or .png might be smaller. 😄

[@Flipsie]

Another I found out has transparency is webm, which I think OBS can use natively so I might give it a try as unfortunately updating various things (drivers etc) did not end up with things working any better :( And if not, I could always try a gif :D

[@Maeyanie]

Yeah, WebM is the standard container for VP8 and VP9 compression formats, so it should support it. Otherwise you might be able to use H.265, AV1, or something inside an .mp4 container; that's also a pretty widely-supported container format these days. It's worth noting H.264 _doesn't_ support transparency though, and a lot of software defaults to compress with it when you select an .mp4 container file, so have to watch for that. But yeah, it all revolves around OBS liking it, which is generally the biggest challenge. 😄 Edit: OBS seems to also accept .mkv containers, which can take a wide variety of compression formats. Generally I find software tends to support .mp4 better, though, so I'd try it first.

[@gum__]

What you could do to keep the greenhouse (and other rooms) balanced is to filter gasses specifically based on the percentages in the same way you're mixing *in* gasses with a script. The script checks the percentages of the given gasses and if there's too much of a certain gas it'll only pull out that gas specifically. And when the percentages are correct you *then* start checking for desired pressure. This would be an extension to where you're filtering out oxygen now.

[@Flipsie]

Yeah, that's probably a less filter intensive way of doing it too

[@Damen994]

My greenhouse uses 4 active vents. One for O2, C02, Nitrogen, and a waste line mixing directing inside the room only. I control the gas mix using IC10 and a gas sensor. Maintains a set ratio for all the gasses turning on the vents as needed and then evacuates via the waste line down to 90kpa after pressure in the room exceeds 100kpa. Seems to work pretty good. I'm not the best with scripting so I used chat GPT for help setting it up and troubleshooting

[@peterward2875]

The idea of premixing down in the gas handling room, so far away... so much running back and forth to adjust. If you're feeding with two or three pumps to the mixed gas supply, the one backpressure regulator can't keep up if more than one pump is trying to add it's gas. Oxygen should be removed from the greenhouse separately, since it's being generated there by the plants. With a minimum percent of O2, and minimum pressure to determine when to cut the filtration machine off. Feed CO2 and Nitrogen into the mixed "feed" back at the gas room, at say a 50/50 ratio of those two. Though single lines of each are the best way to go. Only beans use the nitrogen if memory serves, but everything you have going is using CO2.

[@SuperDriver379]

Would a direct CO2 line right from the tank, with a volume pump controlled by IC-10 solve the oxygen rich problem? a code along the lines of, “If the percentage of o2 is less than 10%, and not over maximum safe pressure, and it’s not too hot in the room, then turn on the volume pump” that would pump pure even possibly hot carbon dioxide, so long as it’s limited by the temperature and pressure safety, possibly enough to keep the plants alive. This could be done even in the gas room if the pipe network to the room is continuous all the way there. Though a dedicated gas sensor isn’t the worst idea. Located near where the air into the room vents are located to prevent overheating if the gas is hot.

[@dacoz]

I'm still very early in the stream so i don't know if this was looked at yet, but are you hitting the max throughput of the one way valve in the greenhouse? Edit at about 2H15 min into video. it looks like that was contributing to the issue but not as much as I thought. a temp fix might be to put a filter on the output line of the room to keep the co2 in the room. It is the less recommended way to run a filter, but with your redundancies it won't cause issues.

[@zugzugtheimpaler4720]

That O2 pump ..... I think it's faulty. Obviously it's leaking. Have you called the manufacturer's Tech Support and seen if you can get replacement? :D

[@111michaeldynes]

What is the benefit of dividing phase change cooling into multiple sections instead of doing 1 loop from the max pressure to the minimum pressure?

[@vault1515]

You dont need that much CO2, I have a greenhouse with about 160 ferns and 9 switchgrass harvested by harvies and i have there 77% of N2, 21% O2 and the rest is CO2, plants are perfectly happy. My airconditioning holds about 23 degrees C. In fact I dont even need to fully cool down the CO2 because there is only max 2% of it so the temp growth is small and perfectly manageable by aircon.

[@Flipsie]

The high CO2 is a safety margin, that's been very much proven to be useful as it gave me all this time to solve my problems

[@ColinRichardson]

0:50 could you not have added a pipe going up, and then a pipe going towards you.. so you can test the pipe on the other side of the wall?

[@Andrew.A.]

Could you use a wind turbine to detect storms? When its power output goes up, there's a storm. Dunno much about stationeers.

[@Flipsie]

Yep, that would be an option as well. Though as people suggested it's probably best to just do it based on temperature since that's the reason I'm doing it

[@Stormcrow_1]

Is it me, or did Splitsie not connect the exhaust of his CO2 filter? right at the end of the stream.

[@ADobbin1]

73% oxygen content in the atmosphere? Its a good thing they haven't modelled real world atmospheric chemistry. With that O2 level your base would explode the next time you flipped a light switch in real life?

[@Pystro]

In order to explode, you'd need some combustible gas. But you might get materials that usually only smolder to light up like they're in a blast furnace (if anything in his base ever gets ignited).

[@benjaminhamilton2434]

Are you really sure water is the best heat exchange medium? At such low pressures (1kPa!) you don't really have that many moles to carry heat, which really limits the amount of heat you can transfer per tick. You should choose a coolant with the highest specific heat*density at the phase change pressure for optimal results. Many people use Pollutant despite its low specific heat, but CO2 can also work.

[@Flipsie]

Pollutant doesn't phase change at the temperatures I'm working at for the main loop therefore it's not even an option.

[@CharlesPruden]

could you not extract nitrogen and pressurize it to a liquid outside, then pump that inside and depressurize the liquid nitrogen to use the power of entropy for cooling.

[@Flipsie]

No, the liquid would still be incredibly hot, but also the game doesn't allow you to get to the sorts of pressures you'd need to make nitrogen liquid at those temperatures

[@manitoba-op4jx]

nvidia's newer drivers are kinda bad for 10-series cards. my 1060 performs much better on their 475 and 525 driver. ask one of your tech-savvy friends for help rolling back, it will be a considerable improvement.
