The easiest way to find vents on your map is to search by temperature. The neutronium shows up as absolute zero and sticks out among everything else.

I can't believe how complex this game is :O I've had it for a long time but never really got too far... I just got back to the game again, and really appreciate your guides. This game is crazy deep!

One **extremely** important point that should be mentioned at the very beginning: all vents, geysers and volcanoes erupt from exact same spot, second tile to the left and one up. So if you don't dig it - nothing will erupt. The thing about tempshift plates you said at the end - Insulated tiles exchange next to zero heat with liquids/solids and a teeny tiny bit of heat with gases. UNLESS! you put a tempshift plate next to them. Those will gladly inject all the heat to anything they touch. So, don't build tempshifts next to walls, unless you want to get better temp injection into walls (there are setups that do that. In fact, all your "metal room cooling" could use tempshift plates.) Consider diamond glass tiles instead of metal for better thermal conduction.

Tempshift plates share heat with all adjacent tiles. If you put them on the edge, they heat up the insulated tiles which can heat up the environment.

I love how many aspects of Chemical Engineering are in this game! I am in my 3rd year of studying Chemical Engineering at uni and it's so great to see parallels between the ideas utilised in industry and in this game!

This guy talks for 2 straight hours in an awesome tutorial and doesn't even ask for a like or a sub, like all other CC's. You have my like and sub!

Love that you're using the youtube time stamps on the videos now! helps a lot :)

I was just getting into using the geysers around my map in my first real playthrough， perfect timing

Hey Magnet! I have over 400 hours in ONI and have JUST tamed my first volcano ever with the help of your video and it feels great!! Thank you for all your wonderful guides.

Vent = Gas Geyser = Liquid Volcano = Solid(ish)

Belatedly, hot CO₂ vents are great places to build Molten Slickster ranches - the vent keeps it nice and hot (which is good because it ensures you get Molten Larva Eggs rather than regular ones) and you can pump in the CO₂ produced in the rest of your base, which the Molten Slicksters will convert to Petroleum, which you can burn for power and _more_ CO₂ (or you can do ridiculous things like feeding it to a sour-gas boiler/chiller, to get _still more_ power off the natgas that results, the downside in vanilla being that you produce sulphur as a byproduct). You can do something similar with regular slicksters producing Crude Oil, but you'll get better energy-efficiency if you use moltens (even if you convert the crude to petroleum, you'll not end up with as much of it as if you'd used molten slicksters in the first place).

1:36:10 about building tempshift plates near walls- it wasn't me :3 , but the thing is that they wil "pump" heat into the walls, afterward heating up the insulated tiles, unnecessary leaking heat. And they will do it in faster rate than normal contact of the walls with hot or cold material inside

I've been playing every now and then but never got to tame a metal volcano, and older guides felt outdated, so you've done me great service with this video, thank you

Thanks for this! I really appreciate your "first the basics" approach. For myself, I prefer crawl-walk-run learning so I really understand what I'm trying to do, how and why. Fancy can come later. 👍

I was like "yeah as if I will ever watch this two-hour tutorial", and two hours later he we are! :D Started the game just this week and I am so overwhelmed by how complex it can be! Thanks for your very simple and entertaining way to explain everything!

This is AMAZINGLY well timed, I was getting frustrated trying to find videos on the internet for how to tame a Steam Vent. Great guide as usual.

36:23 Huge mess simulator...sounds like a great game.

finally someone teaching without making the most compact efficient setups for everything, thank you!

Instead of using the polluted water one to make water, you could use it to sit in a pool to create polluted oxygen, then use filters to turn it into oxygen. Essentially with a polluted water geyser you can choose to make water or oxygen from it depending on the colony's need at that time.

How many years later and i still come back to your complete guide for these things and check it out, thank you for taking the time to make something actually useful.

I appreciate how approachable this guide is. I love the hell out of this game but am hardly at hyper-optimized levels myself, though I like to think I've gotten a lot better. My second run ever I naively uncovered a volcano (I didn't know any better at the time!) and it completely wrecked my playthrough spitting lava everywhere and no longer really able to be contained because no dupe could go anywhere near it even in a suit. I've figured out what to do with most of the more approachable geysers since then, but had still been afraid to try and harness a volcano, and in general ONI is fun as hell but very opaque to non-pro players, so approachable guides like this are much appreciated! Maybe this run we'll finally tame the magma-spewing deathtraps.

best in-depth oxygen not included guide here on youtube. really appreciate it mate.

This video was awesome, while I have been doing some more complicated builds this shows you really dont need to. Would have been a great tip to add an air lock and digging areas into a vacuum rather than always building a big set up and needing to create a vacuum, plus with the air lock you always have access later to fix the mistakes a lot of new players make. So much awesome info and learned some better ways to tame volcanos so thanks again for your awesome tutorial!!!

This is incredibly useful, keep up the amazing work. Thanks a bunch and stay safe

Also, use the heat overlay. Neutronium is cold, and will appear easily on your map that way.

That way to find them is extremely useful. I didnt know thaat i had so many vents "discovered". Thanks a lot. Keep it up.

such a great video for beginners , i ve came back here to see which geysers i need multiple times

I still come back to this video lol. I really appreciate you making this!

Great video! You make the best ONI videos on the internet in my opinion.

Thank you for putting time stamps in the description!

As I expanded my base one time, I found a bit of neutronium with some rock on top. I didn't think much of it, surrounded it in airlocks, and uncovered it. Well, it was a gold volcano. The heat nearly ruined my whole base as I rushed to make ceramic and plug it up with tiles made of the stuff. Several duplicants also almost died because of the 10 kilograms of gold per second coming out at 2700C. That's what finally forced me to make a medical facility.

I just subbed. The long videos aren't a problem for me, I have them running in the bg while I play. Great stuff, now I can go to space. 😊

I actually really liked it being a long video, it's entertaining, and even if I get bored (which I doubt) I can use the stamps to click to a certain part of the video instead of just watching another video, nice!

Thanks to this video, I finally had the confidence to capture a volcano. It was a minor volcano, and I mean *MINOR*. I built according to what you saw, and it produced so little steam it barely got one steam turbine (out of the four) to run for about 20 seconds. My first volcano was a huge disappointment. LOL To be clear, I'm not saying you "overbuilt." I know there's a range of variation in the "productivity" of geysers/volcanos/vents (Like you, I wish they'd choose a name and stick with it). I love that you put relatively simple builds for those of us who have never done this before. The other videos I've seen have made the process much more intimidating.

Looking for a particular geyser. Didn't come here at first because of length, til I got a skill up in Reading Comprehension. Thank you for the effort in assembling this video.

Thankss u! I came back to ONI and the last time I was playing it was in 2017! Your videos are helping me a lot!

Hey magnet, this is a really cool video, so thank you for the tips! I know you just filled the liquid lock of the oil well with water for demonstration purpose. However if it gets too hot the water will just flash to steam so better to have a crude oil or petroleum lock just in case :)

Great Tutorial. Keep it up dude! :D

automation is the secret to taming vents/geysers and volcanoes, good guide dude, also just dropping the oil 2 or more tiles down a granite not insulated box will chill the tiny amounts of hot oil from the leaky oil fissure to like 100 degrees, more after steam turbine tamer.

"Lets fill this up with vacuum first" :D

love the long and well explained approach

I'm subscribing based off the fact alone that you time stamped these

this video is so underrated. you spent so much time making video and it only got 1k likes and 100k views. it deserves at least 5 million views. keep up the great content! love your videos! :)

You can use the chlorine vent to feed squeaky pufts to produce bleach stone to feed a lettuce farm. Very tedious but if very doable.

I've owned this game for 7 years, ever since it came out pretty much. I've still not progressed to the point of producing a single drop of oil. That's how complex this seemingly cute fun game is. And I'm someone who's 100% completed Factorio (including the speedrun achievements) and almost mastered Dwarf Fortress - this game is more complex.

Well timed! and I personally always wait for your guide on ONI because it's so informative and neat with all the time tags, definitely will come back here often :)

I ran into a natural gas geyser early in my current colony and a gold amalgam gas pump can hold in there for a while, I didn't realize it was under the temperature limit until I ran a single pump for a pair of geysers right next to each other later on and that one broke pretty quickly. The original single geyser pump did eventually break too, but right now both are running with radiant water cooling pipes clustered around the pump intake and it seems to work without waiting for steel.

One thing I did with a carbon geyser was to put a carbon skimmer in it. I used a loop to convert it into polluted dirt to feed to pokeshells. It wasn't a lot but it was free material and you can switch it on and off if you want to get some extra polluted dirt when you need it.

I found a carbon dioxide vent! encases it in insulated tiles *DONE* I just lost it lmao

Haha I can’t believe you dumped a dup in scalding hot gas. Sandbox mode turns players into monsters. Thank you for video!

With the quality of your videos and excellent comentary it amazes me that only 4k people are following. Keep up the good work sir magnet :)

I'm watching a lot of this tutorials in a row and is funny couse i have in mind play the ice map so in the back of my mind i'm like "Ah yes, cooling the machines, maybe not a problem, maybe i should use this heat to not die" xD nice tutorials dude

you can put 2 hydro sensors in your water supply for the water geyser, so that when it is too full it will empty a bit of the supply into the liquid storage, and when it is too empty it will empty some from liquid storage

Thanks for the carbon dioxide vent capturing tutorial. 10/10!

Maaan, you really amazing with your videos, thanks for your explanation, really appreciate that ! 🙌🏻

Loved your video watched the whole thing. This'll definitely help me optimize my vents that I got lying around. Also this might not be the best usage but I very much like using infectious polluted oxygen vents to get oxygen just using a deodorizer chlorine setup. Then later use the same one to just absorb both forms of oxygen in the world

This was so friggin cool. Subscribed

Love the "you cant break this" to it getting demolished in seconds lmao

Great video! It was much needed help. :)

Thank you for making it simple🙏😁

It is disappointing how few subs you presently have. Your videos are entertaining, interesting, and helpful! Have you considered streaming? I think you could garner quite a large following if you got you name out there.

I've been watching your videos non-stop for a week now. Hope you come back to make more one day :)

A little late to the party, but I just want to mention an improvement to your cool steam vent setup. Instead of having a pump circulate the polluted water, I use a liquid reservoir in my setup. Use that to circulate the water and then add a second coil of radiant pipes in the pool of polluted water. It will save you the 120w of having to operate a pump.

CO Vent is the best place to set up molten larva terrarium with help of hyper insulation tiles. Cold CO2 geyser is useful for free direct cooling everything along the path you transport it to space.

Thanks for the video. Very helpful.

Nice simple to understand options. Thanks

Thank you very much for this! This helped a lot!

got the game a few days ago and i am grateful that this channel exists, otherwise i would never reach the mid-game!

I foresee that this video will help me immensely! Thank you!

2:00 sandbox mode?!! I never knew that existed! Thx for making this video :)

my bases are still messy as matter of course! thanks for this guide.

as you were describing the neutronium platforms and the priority trick i saw two in my own world and found a carbon dioxide geyser and a cool slush geyser so thanks already

also note that you have renewable water and power with a steam turbine due to producing water and you can use that in the water tanks

just started playing this game, your tutorials are great, please keep it up!

You're such a kind and benevolent master. 16:41

The reason for the temp shift plates not being directly next to insulated tiles is that it interacts and heat up or cool down the insulation tiles(can wast heat or energy) also the heated tiles can heat up the serounding(interacts with serounding gas over a few cycles bout 50-100) so double insulate or save materials by not putting next to insulated tile. Also checker board layout for temp plates spreads heat beter. Comented on the best building materials totorial.

Thanks alot for being detailed on all the vents. Also thanks for showing all the temperature scales available in the game so one can discern on what is hot and what is cold based on their own prefered unit.

Carbon dioxide geysers are good for feeding slicksters. You just have to keep the slickster's environment warm enough. I use a thermoaquatuner steam room with metal tiles next to my slickster farm to keep them warm. I would have built the slickster warming room even without cold geyser CO2, because I try to get the temp up to 140C to get them to hatch molten slickster eggs.

Great video! I've never known the best ways to capture some of these, mainly the ore volcanoes, and this really helped! I have an idea for a tutorial video, one about space! (Shovevoles, asteroid protection, solar energy, rocket travel, etc). That stage of the game is one I am not very familiar with, and would greatly appreciate some help.

Dang those volcano setups... And here I thought I was smart when I finally implemented mechanical filters into my electrolyzer setup

@Maget Thanks for the great video. On the steam vent you appear to go to great pains to fit the automation in the room, why not just have the liquid shutoff and buffer gate outside the room?

Great vid, thanks. I've got about 300 hours in ONI across several runs, yet I never seem to learn anything new on my own. I've been so obsessed with keeping heat production to a minimum that it kinda inhibits me experimenting. I didn't know what to do with vents and geysers because they are always so hot, so I ended up blocking them off and ignoring them Truly amazing game though. As a software engineer I'm pretty amazed at how complex the game is, whilst still performing really well

Note for anyone who sees this: Carbon dioxide vents/geysers have another use, albeit a not very good one like it's other uses (other than rockets) you could theoretically use it to make polluted water from regular water with CO2 skimmers however I'm not sure why you would need this when you have cool slush vents and stuff. It does work if you need more polluted water and you don't have enough from geysers for some reason. But like for the rest of the reasons, it's not practical. Just use it for rockets.

Do you have any guide videos where you do the stuff the normal way, i.e. without "cheater power supplies"? It's not too hard with cheating, it does not produce excess heat and excess gas and such, i.e. more problems you have to deal with. And it's unlimited. The real problem in this game is having to deal with all that stuff while on limited power supply, because every "solution" has its own side effects you have to deal with too, and its really difficult for beginners.

great tutorial

İ was exhausted while watching thank you so much

I love the time stamps so I can jump to what Im working on however, theres then a lot of assumed knowledge thats from earlier in the video :(

Thank you for making this tutorial

This may be months late now, but temp shift plates basically act as a multiplier that causes all surrounding tiles to share heat with each other. This can absolutely wreck a tiles ability to insulate. If you do some quick testing with magma, you'll see what I mean. Always leave space around a temp shift plate unless you intend to share temperature with it. Also temp shift plates are really bad at sharing temperature with each other (in a vacuum). Again, it basically acts as a multiplier of heat sharing between tiles(air, liquid, solid) but not so much itself.

Cool salt slush geyser is the best thing I've found in early game because it's spew out -5C brine which make life much easier heat management early.

thanks for the tutorial! Im new to the game and unfortunately I killed my base trying to cool down water from a cool steam vent hahaha, but well now Ill know what to do

great vid!

Man, Your guides are god level can you please make a video about Rockets and how to go to other planets ?

If I had a CO2 geyser or vent, I'd send it to my slicksters (they tend to starve)

Great video. Helped me a lot. Thank you so much for this. But just out of curiosity. Would you say that Farenheit are a bit confusing with all those croquet numbers?

Very helpful, not sure how far I would get with out u :)

Hi. After I complete Space Out DLC and base game. I actually find out Volcano and Co2 Vent actually more useful than it thought. One of critical building for Volcano is Petroleum Boiler, which is advanced build only for late game and it's more useful than oil refinery in both efficient and simple power generation. Petroleum Boiler will covert 100% Cruel Oil -> 100% Petroleum and some additional Igneous rock from cold Magma rather than 100% Cruel Oil -> 50% Petroleum + 50% Natural Gas. That is critical especially you will use more Petroleum in Space Out DLC. Petroleum can be use for generate power and more exceed water, which will create more power than it own. CO2 Vent at 500°C is very good for Molten Slickter because they will eat CO2 and covert it into Petroleum instantly so you don't have to boil it again from Cruel Oil when use normal Slickter.

HOLY MOLY 1h 47m video. Im excited :D

add gas storage for natural gas in the storage room. you can stack up 20kg of gas per tile (use airflowtile) + the gas storage.

tempshift plates, inject the heat directly into other tiles, which heats up the insolated tiles much fast than they should. Even Neutronium can be heated up in a couple of cycles with a good tempshift plate.
