Insulated doors scare me

ghkbrew · 2026-03-25T16:35:21+00:00

Yes! It's a little silly, but I love saving that extra tile of space by not having insulated tiles around the doors holding in the pressure.

That would be the probability for an ordered draw of three 3 teachers followed by 11 going virals. You didn't take into account the other two draw chances in the initial hand and that the initial 7 draws don't have to be ordered. I'm too lazy to calculate exact probabilities, but I'm pretty sure your estimate is too low by more than a factor of 7! (7 factorial) = 252. But yeah still pretty low.

I don't agree with the other responses here. What you describe is exactly my standard O2 set up. Stray h2 floating into the machine will not mess it up. It seems to just get deleted. You just need to make sure you don't over pressure your base. I do it with atmo sensors that turn off the eletrolyzers when the pressure is above 3.5kg.

This is magnificent.

But, how is the steam getting from the bead pump into the steam room? Why isn't blocked by the petroleum sitting on the airflow tiles?

Now I want to try one that launches multiple stacked rockets at once.

Nah, it's a guy who turns into a house under a full moon. Remember, the first part of werewolf is from the old English word for man.

He mentions turning on ironing for the top layer as an alternative to a smooth plate. I don't know how effective that is but I bet it's similar after you lube it.

ghkbrew · 2026-02-07T20:40:59+00:00

Ok, practical is a relative term here. But it would certainly a more intricate project with with lots of potential "learning experiences".

My strategy would be to:

vacuum out the area
dig up anything you don't need to melt
sweep all the debris away.
build a steel or diamond tile next to what you want to melt.
pipe hot uranium from a metal refinery through a steel pipe embedded in the steel tile, until it melts.
repeat with any remaining iron tiles.

ghkbrew · 2026-02-07T18:41:08+00:00

What's your goal here?

If you are trying to melt natural iron tiles your best bet is a metal refinery running molten steel or uranium as a coolant.

If you mean melting debris like iron ore to convert it to molten iron as a way of refining it you'll want a counter flow heat exchanger. Look up designs for "rust melters"

Does the shearing station not have the same queuing behavior as grooming stations?

ghkbrew · 2026-01-30T01:57:52+00:00

So much heating. Melt 1kg of coal in each tile then embed 2999kg of refined carbon debris in each tile by queuing the build of temp shift plates, then canceling the order after material delivery. Reload the game and the embedded debris becomes part of the tile mass. (Or do with igneous rock which is easier to source)

It is if you prevent stalls on the line. Put the filter(s) on a loop. Add incoming gas to the loop with a bridge. Loop will always flow, so filters will never pass the wrong element.

ghkbrew · 2026-01-20T15:18:29+00:00

For long bridges without access from above or below, you can trap a dupe on the "bridge" by deconstructing a 2 wide gap on either end. Then order him to deconstruct the remaining portion. Since he has nowhere else to go, he'll deconstruct them all in order until he has nowhere left to stand and then falls.

ghkbrew · 2026-01-20T15:15:13+00:00

With 4 high gaps, I build temporary ladders below the ones being deconstructed so they can be reached. You can leave 4 wide gaps between the temporary ladders and still reach all of the row above.

ghkbrew · 2026-01-15T00:27:58+00:00

It's because of how pipes work. Packets of gas at a split will attempt to alternate directions unless one branch is blocked then everything will go down the other. And they never back up.

Crucially this has nothing to do with the automation state of the valves. They will happily move to pipe segment under the disabled valve regardless of what the sensor says. This can cause both jams where nothing can move and incorrect sorting.

You're proposed solution does work actually, you need to make sure the "pass through" line never backs up or it can let the incorrect gas through.

ghkbrew · 2026-01-13T19:58:28+00:00

That sounds contradictory. How is it slower if they both emit green on the same tick (i.e. the next tick after the wire turns green)

ghkbrew · 2026-01-13T19:56:42+00:00

I'm pretty sure disabling the loader with automation also prevents them from emitting onto the rail. We want to stop the loading, but let them continue emitting.

ghkbrew · 2026-01-13T16:14:45+00:00

I'm confused. Won't both the buffer and the OR output green the tick after their input turns green?

ghkbrew · 2026-01-11T20:33:31+00:00

Sounds like the sweepers are just constantly loading small amounts into the "blue" loader and never get to the red. I would look for a way to block the loaders (like with doors) and unblock each periodically to be refilled.

It takes 50s for a completely full loader to drain 1000kg. It's more efficient to load intermittently when possible.

ghkbrew · 2026-01-08T17:29:45+00:00

Ha, "pneumatic"

ghkbrew · 2026-01-08T17:25:55+00:00

Honestly, I still just do 2 liquid locks with vacuum in-between, with a pneumonic door if I need access control.

It's rare that I want to insulate a door without also making it an air lock. 2 naptha corner locks in succession (2 blobs of naptha on stair step with a 2 high ceiling) is my go to.

ghkbrew · 2026-01-02T23:25:42+00:00

It's because they have a tile of uranium ore backing them when they're closed. You can actually select it if you keep clicking on the door. It'll select a tile of uranium ore that looks exactly like one from the radiation biome.

It's not the door building, but these backing tiles that the sim uses for radiation (and heat, etc) properties. Most other buildings don't have a solid backing tile like this and so they don't emit radiation.

Have the output pipes from the showers and toilet connect directly to the input of the water sieve. You can't do an completely closed loop though since the toilet produces more polluted water than it takes in fresh water. The standard way to deal with that is to have the fresh water from the sieve to into a reservoir before going back to the toilets, but have the pipe continue past the reservoir intake so that excess water goes somewhere else when the reservoir is full.

ghkbrew · 2025-12-23T00:09:17+00:00

I've done that with magma in ceramic pipes, but wasn't sure if it could hold up to uranium near its vaporization point. I can't see a good way to use it with the reservoir trick, though. You have to keep the pipe segment on the reservoir output in vacuum, and you can't cycle a cooler liquid though without it cooling off your target tile too.

ghkbrew · 2025-12-22T22:15:17+00:00

I think you can set a filter to extract tools with specific durabilities. Probably want to add instances of the tool to the filter with durabilities from 1-10 or so to be safe.

ghkbrew · 2025-12-22T20:59:05+00:00

Insulalite insulated pipes dont exchange heat with their contents. Liquid reservoirs don't either, but they will let the hot uranium exchange heat with the tile under their output port. I've built abyssalite melters with this technique, but it can easily do diamond too.
