Pre-steel self-contained 100% hot steam vent tamer
I was sitting on my flipped asteroid without transporters and determined I really wanted to tame that steam vent for power and water and funsies. I managed to get a drecko through the Printerceptor for plastic, but I have no access to iron or gold amalgam. Only copper and wolframite.
I came up with a plan: If I have steam turbines and can run them, then I have 95 C water coming out of them, which is less than the 125 C overheat temperature of a copper aquatuner. With this thought in mind, I came up with a build that can tame the steam vent, feed the water in to a mini-SPOM, and cooled the oxygen to about 10 C.
Here are the main highlights of the build:
- Extracts 100% of the steam from the steam vent.
- Extracts the vast majority of the power efficiently from the steam vent
- Has no steel components.
- Extracts all the excess water from the steam room within the dormancy period.
- Very power positive and self contained.
- This should work effectively on any non-geotuned hot steam vent, and could probably be modified for geotuned cool steam vents as well.
- This was built in debug as a proof of concept, but there is no reason it could not be built in survival.
- The steam room peaks at an average steam temp of 206 C with this steam vent, which quickly goes down to below 200 C during dormancy.
First, the physics of the steam room itself:
I built this using my 100% gas vent tamer technique, where I utilize the liquid-gas bypass mechanic to force the steam to leave the critical tile of the steam vent immediately, leaving it open for more steam to come out about a second after the previous one. While this could be used for infinite compression, the steam room will always drain between dormancies as long as there is a place for the water to go.
Since the room is hotter than any pump I can build can survive in, I put in an escher waterfall to force the sulfur to loop. Due to my material limitations, I use sulfur and naphtha as my two liquid required to make this work, but the liquid could be petroleum or liquid phosphorus just as easily. I used about 8 tons of sulfur to fill the loop.
The crux of this build is that I use the 95 C water to cool the copper aquatuner before the water leaves to the SPOM or back to the room.
Here, I have two steam turbines, so 4 kg/s of water. I take one of the steam turbines (the left one) and split it in to 2 1 kg/s pipes to protect the pipes from breaking and run them above and below the aquatuner. In theory, the use of this mechanic/exploit is unnecessary and arguably sub-optimal,as I'm not taking advantage of the boiling temperature loss.
The right steam turbine cools down the lower heat sink, which connects to the upper heat sink via a door. The door closes when the water is below 102.15 C (yes, you can have that level of precision on temp sensors), which has not boiled in the time I have been running this system, which is about 2. This leads to the 2 kg/s of water coming out at about 101.9 C.
Additionally, I also send the hydrogen from the mini-spom through the aquatuner room.
All of this works together to keep the aquatuner barely under the 125 C overheat temperature. I submerged the aquatuner in polluted water, except for 1 tile of 10 kg of nuclear waste (which I have from slamming radbolts in to walls), which has a much higher thermal conductivity than polluted water and helps drive down the temperature faster.
The aquatuner then cools the liquids on top of the steam turbines, which in turn cools the SPOM and the outgoing oxygen.
Here is the automation:
In the steam room, I have a liquid vent with a liquid pipe element sensor, which I am using as a beefed up atmosensor. I want the steam room to maintain a high pressure, so this will send a green signal whenever the steam pressure in the room is above 1000 kg. The liquid shutoff releases a blob of 0.1 g water every 12 seconds, which is always blocked unless the liquid vent outputted it.
In the aquatuner room, I spent a lot of time messing around with the variables. I learned that buildings don't appear to take overheating damage if they only spend one in-game tick over the overheat temperature, so I put in a temp sensor to turn off the aquatuner if the room ever gets above 120 C. Additionally, I turn on the two steam turbines if the temperature gets too high in the aquatuner room to cool it down, prioritizing the left steam turbine.
In the steam room, I have 2 thermosensors. The one at 140 C triggers the left turbine always and it trigger the right turbine if the pressure is below 1000 kg/tile. The one at 180 C triggers the right steam turbine. If the steam room is over 180 C or the steam pressure is below 1000 kg/tile, the water from the right turbine ends up venting in to the steam room.
Some Math: To cool the steam turbines at full bore at 206 C (the peak temperature they hit), I have to be able to remove 96.78 kDTU/s for each turbine, leading to a total of 193.56 kDTU/s being loaded in to the aquatuner.
Assuming my aquatuner is at peak temps allowed by my build, that means that I am heating 2 kg/s of water by about 29 C and another 2 kg/s of water by about 6.9 C. That is a net cooling of the aquatuner by 200.59+57.67 = 258.26 kDTU/s from the water alone. This could in theory be improved by about 1.5 C on the hotter liquid by venting the water near the aquatuner and letting it boil, then further heat to ~119 C before being added to the steam room, probably with a bypass pump.
That leaves an excess of 64.7 kDTU/s of cooling on the table, which can easily cool the SPOM's outputs, especially if I then cool the aquatuner with the hydrogen. The extra cooling potential is about enough to cool the outgoing oxygen to about 10 C. This is assuming the steam turbines are running at full bore on 206 C steam constantly, which they most certainly are not, so the average oxygen output is lower and the aquatuner often lies dormant due, having extra cooling potential.

Question about achievement "Some Reservations"
My understanding is that to unlock this achievement I just need to create 4 nature reserves in a single planetoid. I did that, but for some reason the achievement didn't pop.
Am I doing it wrong?
---
# EDIT 1 - Here we go the screenshot of 4 nature reserves.
Also to add more context, I'm on the 100% achievement run on Steam. And this particular one is the one I have difficulty unlocking
---
EDIT 2 - yes the achievement is enabled, meaning no sandbox or debug mode was used
I was able to collect other achievement just fine

Base falling apart after 8 months break
I have a really advanced base I try to get all achievements on (still need to mine a bit in space, run the reactor and mutate some plants).
I logged in after 8 months and now everything is falling apart: my critters are dying, my petroleum boiler is melting and liquid nuclear waste is everywhere.
Even with reloading the game I struggle to fix it all. Did I miss some big changes (mostly considering temperature and automation because the boiler has the highest priority)
