The most non exploity solution I can think of would be to run tungsten radiant pipes containing liquid uranium through a geotuned volcano magma.

The liquid uranium can be pumped while cold with at 125ish and is liquid until 4131. 4x geotuned magma is 2300 ish. Could even geotune it 5x and get rock gas and cool it down with the uranium.

The hard part is really to dump the old magma somewhere to replace it with fresh hot magma when colder than desired, but that should be doable with a door crusher or just letting the "cold" magma out somewhere.

If you don't have spaced out maybe liquid aluminum could be used inside the pipes instead of uranium

Okay. Now you've got 1326.85°C liquid uranium (and other stuff) coming out of your vents. That's too hot for thermium pumps, without "exploits" like the tricked pump, so how are you handling it?

Plus, you're losing upwards of 1000kg per cycle of whatever you put in, so uranium isn't really practical outside of sandbox (some maps might not have 12 tons of uranium altogether, and it can only be replenished by space mining at about 20kg/cycle per mining POI). Aluminum is better, though to sustain it you would need multiple aluminum volcanoes, magma volcanoes, and thermium pumps, which is silly because the whole point IMO is to get a little niobium for thermium in the first place.

This is my solution using magma. Is auto sweeper diagonal grabbing the solids an exploit?

 

The problem lies in cooling the uranium back down to something manageable. Perhaps just dump in a load of water which is then reextracted with steam turbines in order to cool the uranium to a solid for extraction.

Replace the use of door crushers with supercoolant that only runs once tempratures are such that it wont become a gas which adding water can do?

 

Exploits like door crushers and magma pumps make it vastly easier

I like that build, and it would probably work with aluminum instead of magma, which could be pumped directly with thermium pumps. I don't have much of an opinion on whether or not any of those mechanics are exploits, though whenever an update brings a new challenge, I do wonder how the devs intended players to tackle it, and I'd like to think that they thought it through enough that there's a solution that's practical outside of sandbox mode using only intended mechanics.

[Hokaeru]

Although probably not sustainable, maybe the devs thought of this very "dupe lore friendly" solution :

1. Build a thermium pump, high melting point pipes. Turn off autorepair.
2. Pump super hot magma.
3. Pump and pipes get overheating damage.
4. Congrats on the achievement ! The geothermal heat pump works.
5. Whoops, where does that sour gas come from ? Why has my plastic ladders melted ?

On a side note, to answer the main question of this topic, I think the heat pump is a perfect water boiler for all the Pwater/Saltwater geysers in the endgame when you don't want to make roundtrips for sand.

You cannot pump liquid steel or gold without exploits. the pump would keep overheating.

You can lock dupe near it for infinity repair. It will cost you some ore, but thats fine

Has anyone "tamed" the geo power station in a survival game yet ? Would like to see a practical build in a real game...

There's not much to it. Just slap a bunch of turbines over a geo vent. (8 turbines each for 3x geo vents, or 12 turbines each for 2x geo vents) Here's one such example

[Slavon Blue]

Has anyone experimented with pumping different liquids into the different liquid ports? For instance, maybe one liquid Port gets magma, one gets water and the last gets molten gold. Would the temperatures be averaged across, or does each Port correspond to a specific return POI? Can it even store multiple different types of liquid or is the first one going to block the other two?

And it counts SHC of liquids too so no exploits here...

that is sad, i was planning on puming in molten gold

 

I wonder, how does the storage work, will water past 100c go steam while in the "main body" or does the "fuel" get consumed instantly or how does it work ?

It gets moved into its internal storage just like any other building although its not visible in-game. It's considered both sealed and insulated (contents will not exchange heat with surroundings, contents will not off gas or phase change). The liquids don't disappear until it's full and then it's consumed and computed in one go

So what you are saying is we can't use superheated gold, because of SHC, but we can use superheated water, because the storage is "holy" or what ever it should be called.

 

So no gold "fuel" but maybe use SC or Water i guess. Still, superheating water to 2.000C is gona be a challange, let alone 12.000 kg of it... not to speak about the fact that at 3kg/s that'll still take 6,67 cycles to fill...

 

i wonder what liquid the devs had envisioned would be able to reach the max treshhold, without using special mechanics. 

 

At the moment i only see us using the 10% rule to hit the numbers where we get fullerene / Niobium.

You can totally use liquid gold, although you'll lose a lot of it. The SHC that's referenced is specifically if you put in 6000kg of water and 6000kg of liquid gold, it'll be much closer to the water temperatures because liquid gold's SHC is much smaller than water's.

So if one where to use exlusively liquid gold it would hit the max "bounty" ? 

 

I'd argue using 12 tons of gold would be worth getting ahold of some niobium.. It is just needed as a process starter realistically speaking. 

I do wonder what amounts of fullerene you get from 1 "run". Most likely not enough for more than at most 1 cooling loop. if at all..

Yes, that would work. You get 3kg of fullerene, so that's 300kg of supercoolant (30 pipe segments)

well, that would be enough for the most "crucial" things. 

So 1 maybe 2 runs with liquid gold at 2k celcius or more and you have all the niobium and fullerene you need for the next very long foreseeable future... 

Should be doable with a rather small and simple build. at those masses it's ok if it takes 5-10 cycles to fill for one run...

[asurendra]

If you run all 3 pipes on full capacity GTHP will be full at 400 sec. However thats need 3 bugged pump builds. And a lot of gold...

So i decided to try and get the exotic materials in a real game.

Step 1: Copper Volcano Geotuned 5 times (geotuning not essential but means I accumulated the copper faster). 

A tricked Sweeper/Bottle Emptier setup is used to drop bottles of molten copper, for whatever reason Sweepers can handle molten liquids. Turning the Sweeper on and off (I used 2/1 frequency but it doesn't seem to really matter) results in it picking up a bottle and most of the time dropping it, if it does somehow succeed in delivering the bottle no big deal it just drips back down for another go round.

Step 2: Move To the 15 t bottle of Molten Copper to the Heat Pump, which has been vacuumed out. Empty the bottle and pump it using Wolframite burner pumps.

Theoretically the molten copper should've been hot enough, but various heat losses meant I needed to put at least some of it through a Metal Refinery. A second batch with everything done right would certainly require no additional heat from a Metal Refinery.

I had bought 15 tons of Molten Copper, when the Heat Pump was full, there seemed to be 3.44 tons left, hence it consumed something like 11.5t.

 

For my troubles, 5 kg of Niobium and 3 kg of Fullerene. I wasn't diligent about recovering the molten copper, so I lost about 5t to mining out solidified copper. Of course, that was all geotuned Volcano copper that I did not need anyway.

So do I think this is worth it? Definitely 100% if you have a metal volcano, and the bottles are even easy enough to transport by rocket. Getting Niobium and Fullerene is a pain in the butt and in Spaced Out unlocking the relevant moonlets has long term performance consequences.

Because I am a Super Genius with an entire biome made of sand, I decided to skip the metal refinery plan and just fill the thing with molten glass at about 1910°C. Five batches of 96 glass orders gets you to 12T.

 

It wasn't entirely successful, but it also wasn't unsuccessful.

I think next time I'll only fill it 20% with glass and the rest with cold water. That should get me to about 400°C and avoid filling my steam chamber with not-steam.

Is everything inside very hot?
If it is then adding more water might help to cool things down and get other materials to fluid/solid state and then cool the steam down further normally.

Yes, I just saw "must be hot enough to melt lead" without reading the part about the thing emitting sour gas and hydrogen if the inputs are too hot. By the time I saw this thread I was more than halfway completed and decided to just go for it and see what happened.

The good news is it only took me a few cycles to filter out all the not-steam and send it up the chimney to space. Now I seem to be generating an excess of hot water so the extra is getting diverted to my main reservoir. I've only tamed two of the vents so far, getting to the third will require some strategic digging.
