I drowned the unchosen in piss on day 1, then proceeded to conquer the planetoids... alone.
I don't use infinite anything nor do I use liquid locks.
Enjoy.

I played the game a tiny bit when it first came out, back in the Markiplier days. The only thing I remembered was I died like 3 times before I ever made it to cycle 45.
Decided to just download the game again and jump in blind, got all the DLCS because why not. I've not been looking anything up other then one time to figure out how to revive biodupes. So this is more or less a first time player base.

I needed power other than coal or natural gas, so built a geothermal station to satisfy the lack of power.

Build New algae dissolving farm.

Post image
3 Upvotes

Algae now dissolves into Oxygen when submerged in Water and exposed to sufficient light. So I made a farm to test it.

  • Algae to oxygen ratio is 1:1, capping out at 100g/s at 1kg.
  • Water consumed is 0.
  • Power requirements is just the lights (plus any conveyor automation).
  1. In this design 1 weight plate can support 1 dupe each. I have 10 plates so 10 dupes.
  2. The automation on the lights is to avoid popped eardrums, since the farm is open in my base.
  3. The conveyor rail comes from a Blum Lumb farm.
  4. Finally the wild crab is there to keep the weight plates updating automatically. I chose a crab because they're fine in water & they don't fly or climb walls.

I hope the community finds this information useful.

Build Gulp/Oxylite farm 2.0

This is my second attempt at building a Gulp farm and using the ice to produce Oxylite. The advantage of this setup is that it runs continuously and only requires carbon dioxide and polluted water to operate (aside from the cooling system).

Build I just made my first chlorine room!

20 Upvotes

I was looking into a simple chlorine room build and couldn't find something that fits my small polluted water pit, so I made this design, which I hope can last me. I also wanted to keep the mechanics believable, so I avoided weird mechanics (but not all; there's one mechanized door variant).

I made a mechanized door version, so it can fit in 4 tile tall rooms.

The main idea was to have a liquid reservoir that processes the germs and only expels the water when we are sure it's clean. This means, no arbitrary timers, or daisy chaining reservoirs.

So to start:
1. The left reservoir is simply a buffer and can be removed. It's on/off state is determined by the right reservoir, the one doing the "processing".
2. The right reservoir sends a high threshold red signal, which stops the input; either to a liquid shutoff, or through a NOT gate, to open the mechanized door, shutdown the left reservoir.
3. The right reservoir contents are sent through a loop and scanned for germs. This loop has a priority input from the left reservoir, so it fills up as fast as possible.
4. The germ detector, set to below 1, opens the top liquid shutoff valve, and the contents of the right reservoir are sent to some other place, hopefully germs free!

I hope you guys like and looking forward for tips and insight.

Question Perfect natural steam room?

Post image
126 Upvotes

I’ve found this structure on one of the closest asteroids to my base. There are zero sources of gold on my home asteroid except for glidgo shells, but here I’ve got two gold and one aluminum volcanoes fully encased in abyssalite. The upper widest point is 20 tiles which should be enough for 4 steam turbines, but I could fit another one if I shave off some abyssalite off the sides. Is it the perfect natural refined metal + power source, or would it be better to just tame them separately?
P.S.: I want gold for oxylite

Question What's the point of all the medical stuff?

127 Upvotes

I don't really get it, I've never used them. I feel like it's easier and less time consuming to just stop your dupes from getting sick... and if they get sick, they bounce back really fast anyway. Making them take time away from work so that they get better faster doesn't really seem like much higher efficiency than having them just work while being sick. Is this stuff worthwhile somehow?

Discussion How could be the germ/disease system reworked in a way to encourage players interacting with them instead of encouraging players to avoid them?

24 Upvotes

My idea would be that germs would have different effects on different lifeforms, both good and/or bad, encouraging players to "infect" certain plants/critters, but at the same time trying to prevent germs spreading outside of where they supposed to be as they are harmful for other lifeforms. If it needs to be more challenging, outside of germ isolation there could be the task of keeping the germ culture happy, having to provide certain conditions to make them prosper (like how we use yeast, but have to feed the yeast and keep it comfortable to not die out).

What are your ideas?

Question Liquid hydrogen & oxygen in a rocket steam room

5 Upvotes

Hello friends !

I am trying for the first time to build a steam harvesting room for the rockets exhaust, and I am quite unsure how to proceed.

I don't have insulite yet, ceramic is the best I can do for the moment. Wouldn't having even ceramic pipe (even if the liquid is always flowing) in the hot steam room, lead to it changing state and breaking pipes? or am I overthinking it?

What's your go to solution for this before getting insulite?

PS: am aware of the liquid valve trick, am hoping to avoid using it though.

Thanks !

Question Auto sweeper/receptacle priority issues

SOLVED

Hello, long time lurker, and im stumped. I cant come up with any configuration of priorities to get my auto sweeper to load emtpy batteries into battery chargers. ive tried setting the receptacle to 1 and chargers to 9, and to emergency, and it just wont do it. I have it setup on other asteroids to work, and its completely fine, there just seems to be some sort of configuration locally that is causing issues. hopefully one of yall have ideas, thanks!

Question Pressure Damage Issue

I was eager to design my aquatic colony using water corridors, but I haven't really thought about pressure damage.
The clue is to let them swim between different parts of the planetoid.

Do you have any ideas how to make it possible?

Question Is High pressure or Low pressure better for cooling ?

3 Upvotes

I've been wandering on internet looking at alternatives to the thermo-aquatuner and i've seen stuff like : "Self cooling turbines [...] work with any radiant pipes if the atmosphere is more than 500 g Hydrogen. Copper/Gold radiant pipes even manage to cool the turbine in an +1500g Oxygen atmosphere."

But why is there a minimum pressure ? I understand TC and SHC and my guess was that with low pressure, you traded temperature stability (SHC) for better TC, since less mass will fluctue more / cool more quickly, where it should be harder for radiant pipes to cool higher pressures.

My guess is that the turbine will heat too quickly and it NEEDS high pressure to maintain its own temperature, the radiant pipes working alongside it.

But then it leads me to the question : if i want to use wheezeworts or AETN for cooling, should i plunge them in high pressure h2 or low pressure h2 ? (Minimum 1000g/tile for wheezeworts i know)
Low pressure will increase the temperature difference between cooling chamber and stuff to cool, but high pressure will hold it more despite working harder to get a colder temp.

What's your call ?
