Just some heads up, if the magma starts to not flow through the second mesh tile, you probably have a certain bug where the magma becomes an igneous tile inside the mesh tile. To fix this, deconstruct the mesh tiles, save and reload, find any igneous tiles where the mesh tile is before, and dig them. This should fix them from turning into igneous rock inside the magma line.

[@GCFungus]

That is true, and is caused by having too much magma in the tile when it solidifies. That's why it's important to use the magma blade to carefully drip it in and not have it go in large amounts. As you say to fix this you can deconstruct the tile, dig the rock and then rebuild.

[@anomalocaris9298]

4:55 When I'm using Smart Batteries to control the turbines, rather than allow one turbine to continue running like you're doing, I actually prefer to just put a failsafe on the Aquatuner itself (with an AND gate and a nearby thermo sensor) that stops the Aquatuner from running if the steam temperature is over 300C, thereby guaranteeing it doesn't break itself.

[@GCFungus]

That's a neat solution, thanks for sharing.

[@blavena]

Awesome designs, and you can even clean the salt with shipping before taking the igneous rocks for a ride Sadly my home planet has no oil, this is probably the best I can do with the 3 vulcanoes there, I also added a spike to the left to build my sauna there

This was a great tutorial of something VERY difficult. Thanks.

[@Kawaii_duck]

For the heat injector set up, i would recommend u guys to power up the mechanized airlock so it closes and open faster. That way u don't bring in more heat than needed. My set up would get overheated when I didn't power up the mechanized airlock. Also move the thermo sensor closer to the middle. Hope this helps anyone who has a problem with the injector set up.

[@GCFungus]

I've not had this problem, but I can definitely see it happening depending on the exact set-up. And if it does then powering the door seems like a sensible solution.

[@Derpaholic_rex_games-wr2pw]

I had a similar situation, but determined that mine was because i had too little steam in the room, i made sure to re-build with enough water to get the vents just below overpressure (like 900kg per tile including the "vacuum" tiles to be filled), and my overheating problem went away. You don't want the vent to actually overpressure, or the return water can boil in the pipe

[@GunGryphon]

Another lazy way to do geothermal is to "bottle" the volcano inside a large diamond window container and siphon the heat with a heat injector. You can start the process with a heat spike above the volcano till everything is cooled to neat boiling, then dig out an area and change the spike into a bottle. As the lava builds up to cover the volcano, just mine it out every few hundred cycles.

[@GCFungus]

I must say that I have never heard of that method before, but I see how it would work. In general I tend to prefer designs that I can leave and forget about, but this way is probably quicker and easier to set up, so a benefit there.

[@Somebody374-bv8cd]

When I watched the video by sharkiii about completing ONI without liquid pipes, I found out that you can basically reset the temperature of any solid material in the game that starts higher than 45 degrees C to 45 just by building something with it and then deconstructing (anything works, but tempshift plates are a quick way to use up 800kg and can be built out of almost any solid material). So technically if you want the igneous rock from the magma (to feed stone hatches most likely) from the geothermal power plant, a lazy way would just be to drop it somewhere and have your dupes build a massive amount of tempshift plates and deconstruct them.

[@GCFungus]

Is that still the case? I'm not sure if they made any changes to that, because recently with the frosty planet pack they had to make a change to buildings made out of mercury because it was setting their default temperature to above mercury's melting point, so all buildings instantly melted.

[@Somebody374-bv8cd]

@@GCFungus I'm not too sure about mercury in particular, but I know that when I made the insulated tiles from ceramic for the volcano that will supply magma for the petroleum boiler I'm attempting atm based off your video, they all reset to 45 degrees despite being over 80 degrees C initially (since I kept the klins in my steam room). Which was extremely helpful for containing magma and making sure the nearby areas didn't heat up. I believe it only applies if the material is already hotter than 45 degrees - ice certainly seems to stay at negative when I make tempshift plates out of them. I'll run a quick test from my old save when I still had 1500 degrees obsidian around and hope they dupes actually pick up those to build.

[@Somebody374-bv8cd]

@@GCFungus I just tested it with 1500 degrees obsidian, and it does reset the temperature to 45 after building and deconstructing. I think this works only if the material is already higher than 45, ice tempshift plates always stayed at negative after building.

[@michaelsotomayor5001]

There's one more option to harnessing magma power, my preferred method - using hydrogen filled steel pipes to slowly drip cool the inflow magma from a volcano. Pools of magma is different but if the volcano is in a pocket of obsidian with surrounding magma I mine all of the rock out and cool down the magma into a crust using igneous tiles. Then I dig the entire volcano out free with no liquid magma to deal with. From here setup to catch the magma and cool down easily with a hydrogen filled loop. You can easily gather tons of igneous rock this way for future use in any project you need heat power.

[@Tantow]

I really enjoyed this tutorial thanks

[@deilusi]

There are variations of it, for example if you open magma blade that flows into tempshift tiles, it will also turn into debree and do nothing else. its useful if you just want to compress magma into rock, to unlock new area. Then you can store stacks of 100T of hot rock, without big ass room for it. Good part of it is that it usually happens at astonishing speed, as flash point mechanics are a bit glitchy.

[@OneOfDisease]

I am playing on the flipped lava planet as my main starting planet and my first window tap was coming in from directly below. It works the same I guess but logistically it was a lot more of a pain to set up. If I could go back in time I think I would have set it up like your first example.

[@Tsheets333]

Thank you so much! You have great tutorials!!

[@sneezyfido]

I'm wondering about something. This thought takes off from the diamond window spike. How would it be to turn the magma area into a giant steam room? The purpose would be to mine it out and be power positive for the duration, which could pay for a conveyor track, maybe even a miner. The way I see it happening, I would set up a set of steam turbines just above the magma region on one side of the map (specifically, at the end where a volcano sits right above it on my current map), pump in water based on steam pressure, access through a liquid lock to mine out rocks. The steam would cool a wall of newly formed rock, which I could mine and set on a conveyor to dump it under the turbines. Keep shifting the sweeper to follow the receding wall. At about midway, I think I would build a new set of turbines to replace the first one. I love how this game sets my thoughts spinning.

[@sneezyfido]

Ooh! Actually, maybe I should place a sweepy droid instead of arms. And when it's all done, I could mine the entire map from bottom to top using the same pickup system.

[@GCFungus]

Yep it's definitely possible to freeze all the magma into rock and mine it. If you are going to put the steam directly in contact with the magma though, it would probably be better to put an aquetuner in a different steam room as it would probably get too hot if directly exposed.

[@sneezyfido]

@@GCFungus sadly I will have to hold that thought. My first surviving colony sort of.. died. On the left side I didn't quite realize the enormous cloud of CO2 that was bottled up in my first ever combustion setup of 4 ethanol distillers and an engine. Which wouldn't be lethal because I had an enormous sink and an active outlet into space. Except that at the same time my experimenting around that volcano led to a rupture in the insulation between a large patch of oil and the magma layer. On one hand, I got to witness the general principle of dumping a load of liquid into the magma to solidify it. On the other hand, that caused an even more enormous cloud of sour gas to flood my living area from the very same sink where I needed the CO2 to go to. Long story short, I have a large store of meat packed away in sterile atmosphere. Just... ignore how much the wrappers look like, y'know, clothing. Back to the drawing board with the lessons learned from this attempt.

[@sneezyfido]

I tried this now. At first the setup was based on a line of diamond tempshifts reaching down into magma. These were extremely slow to transfer heat into the heat injector that connects to the steam room. Each plate would first equilibrate at midway between next and previous, and then slowly increase in heat over time. Then I added a vent with a liquid cutoff linked to an atmo sensor inside the magma room. Sensor is set to below 1 kg. The cutoff is in the area with better controlled temperature, since the vent is too hot to have water in the pipe. A bit of steam made heat transfer towards the heat injector practically instantaneous. The steam room sits at a constant 199-205 degrees. One really cool observation after many cycles: I see a slight temperature gradient throughout the magma layer from edge to edge, with this machine at the valley. It will take a very long time until anything solidifies. It would be cool if a large chuck were to flash into a chunk all at once. Doubt that I'll be quite so lucky as to see it happen.

[@musdale1]

Hi there, i love your designs and the way you make these videos. I recently made this design of yours (with solid shipping) only difference is that I had to put my steam turbines to the left of my volcanoes since that was the only space left after the volcano pit. It worked well for a while but after some time, the hot igneous rock decided to get stuck on the top mesh tile (it's also not clickable I just see it there). Normally it worked exactly like you showed in the video. Do you know any way to fix this ?

[@helessar9373]

Just saying but i got a problem, my magma doesn't turn into item while behind a mesh but become a bloc itself... So it stays behind the mesh but in a solid buggy bloc that bloc all exchanges and magma cannot flow through anymore... Did that happened to you ?

[@GCFungus]

That happens when the mass of magma in the mesh tile is too high. It becomes too high if it cools too slowly or the magma is emptied in too quickly. That's why it's important to use the 10 tile long magma blade design that slows the magma flow rate at the end to avoid this problem.

[@helessar9373]

I just checked back what was different and i had 11 blocs not 10 from the magma source, don't know why it was a problem, but well i copy pasted what you showed and it works so... I'm happy with, thanks for the reply.@@GCFungus

[@mysterio7385]

How do you create the 100kg/tile liquid layer? I tried to put the salt water on top of regular water, but it just split into two tiles next to each other

[@GCFungus]

Salt water is heavier than normal water, so I would say put the salt water in first. That way you can carefully get each layer to the desired amount.

[@GCFungus]

Trial and error is what the game is about. I'm sure you'll master it with enough persistence! Just remember to try and keep a vacuum to magma areas and the heat won't spread. Then just be careful not to put the dupes into the magma directly so they don't get injured.

[@bodemantube]

I've built a magma spike steam chamber with ceramic insulated tiles below on the magma side and igneus rock ones up top. Everything in the steam chamber is made of either steel or ceramic. I fill the cooling loop with polluted water. Now I run into a problem the moment I close the mechanical door and let the heat from the magma in. The insulated liquid pipe that is directly connected to the output of the aquatuner starts to take damage and lets some polluted water into the steam chamber. This then turns into dirt and sand in the chamber. I thought about just letting it go and leaving the dirt and sand in there and letting it keep working, maybe I could've even ignored that. But the bigger issue is that one pipe that is taking damage. What can I do? Am I missing something? Is this a bug. Hoping you can shed some light and help me fix this issue.

[@GCFungus]

It's a little difficult to help without seeing the exact set-up, but sounds like there's a heat transfer issue to that pipe. If you want to share some pics then I'd suggest heading over to the discord where myself and a great community will help: discord.gg/bnqYAUTMmn

[@AbsalomIndustries]

I've been having this problem constantly with all my aquatuner setups that utilize insulated pipes, steel aquatuners, and steam cooling loops. There's always a tile that gets damaged behind the aquatuner and it's led me to run liquid locks with atmo suits on every cooling loop just so my dupes can perform regular maintenance. I thought it might have been me accidentally freezing the coolant but even when the temp is set to well above the 14C variable threshold (that is, the aquatuner is set to well over 14 C over freezing the coolant), I would still end up damaging the pipe segment and in many cases leaking coolant into the steam chamber, where in cases that I was using oil as the coolant, totally screwed up the system and caused overheat damage by preventing steam formation.

[@GCFungus]

@@AbsalomIndustries That's interesting, but systems like this can run without this problem. Marcelo came over to the discord and we found that he had put his thermo sensor too far from the heat injector, so the whole room was getting much hotter (500 degrees) than he was aiming for. Also he had joined one of the steam turbine outputs to the cooling loop plumbing. If you're having this issue then we may also be able to help with that. It shouldn't be necessary to keep repairing this kind of build.

Could i use crude oil to cool the steam turbines as it has 4x the thermal conductivity of poll water and it has a 400C flash point?

[@GCFungus]

Oil is a worse coolant than water because it has a lower specific heat capacity which is the most important thing for a coolant in ONI. I explained in the dedicated Tutorial Bite, but because the aquetuner removes a fixed 14 degrees, the heat removed is proportional to the SHC.

[@charles0423]

@@GCFungus ohhh that makes sense thanks

[@RalphVincent]

Can we add more steam turbines?

[@GCFungus]

You can add more turbines to generate more power, but this will use up the heat in the magma quicker. If using a large pool of magma (for example from a hot core), then this should be fine. If you use more with a volcano source, then after an eruption, using more turbines will take more heat out of the magma than is produced so you will make more power to start, but less power near the end of an eruption cycle (and through the dormant period).

Mr fungus, youve said that the magma only flows 10 blocks correct? So say I build a containment room similar to the one at 2:16, and I put the steam room on the right hand side of that, but the difference is that i only have one volcano for the room. What do I do if say, get into an inactive period for the volcano and since magma only flows for 10 tiles theres now just a shit ton of magma piled up in the left corner of the containment room. So how do I use all that thats stuck there now because the volcano is on the right side of the room and now the whole thing isnt making any power

[@GCFungus]

At that point I just wouldn't use that magma. It's basically a buffer that should remain there forever. Any new magma that is made at that point will then flow straight through, so the key is to try and use as much or less than the volcanoes produce or you will get production gaps.

[@cowboybeeboopbop]

Mr fungus, im having an issue where I have the magma dropping into the mesh tile but its not going down into the tile itself and theres simething like 46tonnes of igneus rock just stuck on the tile above the door and it wont actually send it to the tempshift plate. Any idea what happened? The door is set to close after 4 seconds and the other buffer gate is set to 15, is it an issue with that?

[@GCFungus]

Usually I would guess that the mesh tile itself is full of solidified igneous rock (the artwork doesn't show it clearly but you can see if you hover over it). In that case you need to deconstruct the tile, dig the rock and rebuild it. The key with the magma blade is to not let too much magma get into the mesh tile at once or this will happen.

[@cowboybeeboopbop]

@@GCFungus ok so, I tried that earlier and noticed that a little bit, so how do I dig the tile? I could see that it was there, I just couldnt dig it. And what would I do to not let so much magma in? Change it from being open 4 seconds to 3 seconds?

[@GCFungus]

@cowboybeeboopbop To dig the tile you must first deconstruct. I would make sure the magma blade is exactly the right length at 10 tiles as shown. Then yes you can adjust the time down too to see if that helps.

Can you do Geothermal Petroleum Boiler next ? Man, played after months of patches, I was surprised now magma solidifies faster at 1400' C, guess they nerfed it hard~

[@GCFungus]

I covered petroleum boilers in the other tutorial bite, and the heat spike here. My hope was that by covering both of those, I gave enough info to put the two together. Basically take the petroleum boiler design as I showed, and connect the hot side of the heat injector to a heat spike as I showed here, down into the magma. I don't think there was a change to the mechanics, and the heat being pulled out of the magma will depend on how efficient your boiler design is. That's why the counterflow is so useful, as you only need to take ~10 degrees out of the magma to heat the incoming oil, rather than say 300 degrees without the counterflow. If your magma is cooling very quickly then I would guess that either you aren't using a counterflow, or it is not working correctly to heat the oil.
