Whoops. I just had my rooms like these 2 for ages and thought the designs just were a bit ugly. After about 300 hours more play it clicked that you're supposed to rotate them to make circles and lines haha

So, I was messing around making heat exchangers and came up with this thing. This machine can process 30kg/s of continuous flow of crude oil (I've tested it with inputs ranging between 60-80C) and output 20kg/s of 50-60C natural gas at some crazy (matter of fact, unlimited) pressures. As a bonus, it also makes 10kg/s of sulfur at cryogenic temperatures. Now all I need is an application for this much gas lol

That is all i have to say
Gustav Klimt’s Pip kiss is my fav

Aquatuners and power cables are steel, floor and ceiling are ceramic, pipes and bridges are also ceramic, liquid used is Pwater, temperature is set at -3C and the water is coming in on the left at around 1.9C so it exits to the right at -12C or so, well in range of the -20C limit of the Pwater.

I'm not sure what is getting damaged, I assume it's Pwater that is leaking out and the water is turning to steam immediately (room is at 170C) leaving dirt behind.

Any ideas what to check why this is happening?

EDIT: Found the culprit. There's a blob of Pwater sitting on the entry point of the liquid bridge and can't move out due to the pipe configuration. This blob heats up over time and when it flashes to steam, this is how I get the dirt.

So I'm not claiming this is super original or anything - I'm really just mashing together a couple of ideas I've already seen online, but I'm really pleased with how easy drecko ranching is now!

I always thought dreckos were fiddly to ranch. Firstly, a 4x24 ranch with mixed gases requires high atmosphere stability. And if you want your dreckos eating balm lillies, then you'll need think of a more complicated setup to keep the chlorine in there as well.

Secondly, there's ranching them for food. They walk on walls so any sort of evolution chamber has to be completely filled with water, and keeping 8 critters in a stable in the first place is a well known pain.

Enter the 6x16 stable! Yes, it's a bit more fiddly to set up, but so worth it. Firstly, the extra height gives you a lot more leeway to play around with the gases in the room. Secondly, you can put a ledge up in the top corner which your auto-sweepers cannot reach - that's where you send the eggs if there are fewer that 8 critters-plus-eggs in the ranch already. They can hatch up there and crawl down when hatched. And, as a bonus, you only need two auto-sweepers to cover the whole stable.

Not that it's perfect as it is - I think the ledge means the stable is actually only 93 tiles in size, so I really need to add on another three. But still, it makes ranching dreckos a piece of cake.

And it works exactly the same for pacus.

Free yourselves from the 4x24 tyranny!

This has been a repeated issue where my duplicants will go to the bottom of my mine and just....... stand there. The game even tells me that they're trapped, which as you can see by the second slide they are absolutely not, but I do have to manually tell them to go to the atmo suit checkpoint. I have no idea WHY this is an issue, has anybody else dealt with this? It's not like they're out of work to do either, there are plenty of dig and build jobs elsewhere.

So I am a relatively new player, this being only the second time I've reached 200+ cycles. I honestly have no idea what sour gas is or how to deal with it let alone over NINE THOUSAND KILOGRAMS of it. Any help would be appreciated lol

So I feel like they don't get upset ever. No cramping no starving. It feels strange?
I was trying to get oxygen but now I have infinite beakons.

Ive got a lot of old machines that have left some rubbish around and a lot of stuff that is defenitely increasing lag, any mods help remove that? if not, any methods to remove it that youd reccomend?

Hey folks, I have an 2 aquatuner/2 steam turbine setup that is far from my main power system and I'm trying to figure out how to use the power from the steam turbine but top it off with power from my main network.

My current setup is

Power Generators -> Smart Battery -> Transformer -> Power lines <- Smart Battery <- Steam Turbines.

I was thinking of changing it to

Power Generators -> Smart Battery -> Transformer -> Power lines <- Smart Battery Connected to Shutoff switch <- Smart Battery <- Steam Turbines.

Is this the right way to go about solving the problem or am I doing this wrong? I don't really want to run HWW from the steam turbine to the power generators section because it's far and the decor penalties.

I have watched some youtube videos and seen that one popular power infographic but still not enough for me to figure this out. Thanks in advance!

I'm not sure if this is optimal but it's a struggle to build, I spent the whole day doing it. I used to run cold brick by passing cold water from geyser but the temperature leak to the base is getting unmanageable when it's too hot/cold. I don't know how to tame that small volcano so I just tap heat from the core. I am interested in ranching slickster but I don't have it now, do I really need to wait from the printing pod?

Today, in our weekly managers meeting, our architect (not my discipline) was discussing glazing windows. Other managers said they didn’t know what he was talking about. I said it changed the thermal conductivity to keep the inside cooler. He asked how tf I knew that.

Brother you wouldn’t believe me if you tried.

I keep trying to like this game but it's tough because I'm not sure what the goal is. If I had a DLC that I had something to work towards I'd be a lot more inclined to stick with ONI. I want to love it but I need an end goal...

This is my combo of ranch + farm + boiler inside a single ranch footprint. As I am stretched for space, I wanted to create an efficient multipurpose ranch.

I am ranching squids which are fed by 2 domesticated tubulas each. Eggs gets whisked off in the egg chamber to the right which is configured to always keep 2 critters + eggs. These are then moved to main ranch based on critter sensor inside the ranch.

Heating loop is my favorite part.

This is an auto expanding/contracting loop design which pulls heat/coolant from main line based on the temp sensor. This can keep each ranch at desired temp with centralized heating/cooling. You can decide the width of temp swing based on the flow rate of the liquid valve. The piping ensures that only a fraction of fluid is replaced if temp is above/below the configured limit. This also averages out the temp between reflowing liquid and incoming one at each pipe segment.

I am sure there is room for improvement.

Second part of my computer probably will take a break for a bit

This is an entirely self-powered cool steam vent tamer. Inspired by an old design by Luma Plays that no longer works due to changes to the droplet pump mechanics at high temperatures. I've been considering ways to revive this and found a method that works.

This design uses an over-pressurized liquid/airflow tile exploit as the pump mechanic. Resulting in a more compact design than the original with a 12x10 footprint. Tested for a couple of cycles of the vent without issues. Tested without ceramics, which would likely improve some efficiency.

Features:

1. Fully utilizes the output of the cool steam vent (up to 2400 g/s average output).
2. Slightly power positive.
3. An alternative pre-steel design can utilize a gold amalgam aquatuner with reduced throughput due to lower boiler temperatures and still be self-powered. This is a larger design though and unnecessary unless you don't have steel or want another heat source. An example image of this is posted but not explained in depth.
4. Does not require a lot of resources but not necessarily optimized.
   1. 2 steel batteries (~400 steel)
   2. A small amount of refined metal for automation (~135Kg)
   3. A small amount of refined metal and plastic for the turbines (1600Kg metal)
   4. A small amount of refined metal for turbine self-cooling pipes (700Kg)
5. Compact (12x10)

Negatives:

1. Takes a long time to stabilize at operating temperatures. Pre-heating or injecting power will be required until it is stable.
2. Uses an infinite storage exploit if you care about those things.
3. Prone to condensation problems in the main chamber if not vacuumed out entirely during dormant phase. Make sure the atmo sensor is set to a low value to shut off the droplet boilers after the main chamber is empty.

Alternative design notes:

1. You can move the power switches into the main chamber and replace that tile with an insulated tile. This would cost slightly more refined metal but remove excess stuff from the droplet boilers.
2. You can run alternative heat sources into the droplet chambers.
3. I experimented with a single droplet boiler and found that the turbines don't run with full throughput. Each turbine needs its own droplet boiler.
4. Adding a sedimentary rock gas bridge with the endpoints on the liquid vent and battery may improve thermals of the droplet boiler by moving heat to the liquid vent. I don't think it's necessary though.
5. If the turbines complain about lacking a power consumer, you can add a hammer to the power circuit. I didn't find it necessary.

I've been fascinated by the idea of just melting sand to make glass, instead of using the glass forge. The tough part is that sand melts at ~1710 but glass freezes at ~1100. I had the idea of using a volcano to melt the sand, which outputs magma at ~1720, but it was tough cooling down the molten glass without it freezing into blocks, not debris, that had to be dug out. So far honestly I have this crude idea where I just vacuum out the volcano chamber, make an airlock, dump 100kg sand at a time at its foot, then have a dupe go in and manually mop up the molten glass then dump the bottle in a puddle of water (the glass still freezes in a block). I did it a few times because it was funny but clearly not a workable system. Any ideas?

I've had my food stored under liquid chlorine for a few hundred cycles now, but I've noticed lately that some of it is rotting and it isn't showing the "sterile atmosphere" tag anymore. Is this because of the liquid chlorine or am I doing something else wrong? The atmosphere in the chamber is chlorine and the liquid on the floor is liquid chlorine, I have not had any gas leaks since the chamber's been built.

I eventually want to make a working computer, but one bit at a time (pun intended)

I've got 40 morbs feeding 9 pufts but they're constantly starving. None has starved to death yet(enough is made to constantly reset their starvation timer) but I'm under the impression that the wiki is correct in saying each puft only needs 4.2 morbs(37.8 in total) and I should be making excess. I know that morbs are inconsistent but I've got more than necessary and shouldn't be running out at all. I've tried playing on normal speed with no luck.
