The SCUM

[lunazone]

Hello! I built a little compact, stackable, self-cooling, and optionally self-powering little module.

Inspired by SPOM I wanted to make a much tinier, less resource intensive version. The changes to make it cheaper to power/build are the ditching of the temp-plates and metal tiles and having two gas pumps as opposed to three.
As you can see I have a little shutoff gas filter set up, for those unaware placing a gas pipe element sensor next to a shutoff allows you to make a cheaper filter by only allowing what you set it to through, and throws anything else down the pipe. The one in this build is set to Hydrogen, and the ATMO sensor is set to above 500 grams. The right room is filled only with Hydrogen no templates or anything. As you probably see there's some ice at the bottom of the plants, I had a little puddle there to improve the cooling rate as it scrunched the Hydrogen up

Let me also explain something, this build is optionally self-powered, you could totally just send all hydrogen to an AETN and what not.

One more thing, that wheeze room get's pretty darn cold, so you could use the very cool oxygen you get from it to cool off stuff before you vent it out.

2 pumps only electrolyzer setups have tendency to delete hydrogen or affect proportions of produced gases. You should test your build for that and make sure non of this is occuring.

To test make a 2 storage rooms and store produced gases there. Run your build for a few cycles and check if stored amount of gases is as expected to be, based on daily oxygen production reports. Or you can just pump for example a 100kg of water to electrolyzer and check if it produced 88kg of oxygen and 12 kg of hydrogen.

In which aspects ? You claim you wanted it to be less resource intensive but didn't explain anything about that...

AND the room for the wheezeworts can't be made easily. There's no free space for a vent to fill it with hydrogen. Too much hassle to build in my humble opinion.

By changing the layout you could make it even smaller.

Ah sorry, I forgot to include why it's less resource intended, the SPOM uses harder to obtain resources such as tungsten for temp-plates and metal tiles. It also has two gas pumps opposed to three.

The room can be made by first creating a water airlock and digging behind it to create a vacuum, once you fill it with hydrogen just deconstruct the vent and pop some wheezes in.

In generell I use up to 8 ww to cool my O2 instantly to -60C then use it to cool incoming water from geyser (100C) down to 0C in seconds for necessary buildings, rest gets used as hot as it comes in. O2 leaves with 0C to 20C, perfect for living areas, most of cold O2 isnt even used for water cooling so it passes base with -60C. O2 excess goes right to ww cooling chamber again, cause my pipes are looped.

There may be something funky going on I only got 10 Kg of hydrogen, going to test again though.

Well, there is a reason why the original SPOM build has 3 pumps

Also make sure to pump all gases from electrolyzer chamber to storage areas, even after electrolyzer stops to work after using up all water.

A little thing to note: your current setup will not function continuously. This is because you do not ration your hydrogen properly and only run the generator when there is an actual need to run the generator. As such, you're wasting a lot of H2, so much even that it is possible for your setup to shut down due to lack of power.
What you need is a smart battery and some automation to only run the generator when you need power. You also need a way to deal with excess hydrogen once you no longer waste it.

Also it isnt exactly stackable, you can duplicate the same build on top etc but you can do that with anything, but you are going to have a large amount of wasted space if you have one above the other.

4 wheezeworth are too much, even if the pumps run at max of 70 degree 1kg/s of oxygen they will cool it down to negative temperatures, might take a few cycles before you see it, but it will.

[neoazureus]

For those who ask, make a hydrogen chamber like that is easy. Hydrogen is the lightest gas, so you only need to build that chamber, put the wheezeworts and destroy 1 or 2 tile below wheezeworts, and build a gas vent there, pumping hydrogen will displace all the gas in the chamber, causing the hydrogen to rise, then destroy the gas vent and build the tiles again. I do that in all my wheezewort cooling chamber in survival mode

No, each wheezewort cools down 1Kg of H2 by 5°C every second, that's 1000 * 2.4 * 5 = 12Kj of heat removed, or 48Kj with 4 plants.

Assuming your electrolyzer is working at 100%, you're getting 888g of 70°C O2 every second. 48Kj will bring that temperature down by 48000 / (888 * 1.005) ~= 54°C. So after the system reach equilibrium you'll be getting 16°C O2 out of it.

You can get negative temperature if your electrolyzer is overpressured and generates less O2 than it should.

Am I the only one who thought after reading the title that Otto left the access door to the germed polluted oxygen open and flooded the main base?

[psusi]

Why are the pipes looped around in the electrolyzer room instead of taking the shortest route out?  Why not put the valve in the electrolyzer room too instead of having those pipes on the top?

What kind of SPOM have you been building?  You don't need any such thing.

Not true.  When the generator runs it charges up the battery to full.  The generator stops for periods of time, but the battery has enough juice to keep things going until more hydrogen comes to the generator.

What he's meaning is that you're wasting hydrogen.  Yes, the battery charges to full, but the generator doesn't stop there.  It keeps going until all the hydrogen is gone. Using a smart battery to automate the generator will only burn hydrogen when the battery needs charging.  Then you can save the excess hydrogen somewhere for use later.

That's why I connect spoms to my central power circuit with heavy wires. The generators are still burning H2 constantly, but at least the surplus power can be used everywhere.

[TheScaryOne]

I won't run any consumable power until I get smart batteries.

This is the reason I said he's wasting H2. In fact, because of this, the generator will burn so much H2 that during times that the pumps are sucking up O2 and there's no H2 being sent to the generator, there's a chance the battery will empty out, shutting the whole thing down, before new hydrogen reaches the generator.

So IMHO, a smart battery is pretty much a requirement for a self powering electrolyser to keep running.

Yes, it is wasting hydrogen but you also don't want the hydrogen to back up and stop the oxygen production.  These days I also just put the hydrogen generator on my main heavy watt bus so the power can go elsewhere, but in my first game I had a setup like that and it never shut down.

[suicide commando]

It can shut down, I've seen it happen. Hence I always use automation nowadays. As for the excess hydrogen, you can simply store that somewhere else if you want for later use, I usually build a 10x10 room with a door pump for it.
