Never quite understood vents and geysers until I saw your series. Its nice to know how to tap into these renewable resources

[Tamizushi]

If you heat the water from your cool steam vent instead of cooling it, you can tame it using steam turbines and ultimately consume less energy. Also, cooling the water may be useful but it's not always necessary. Most uses for water can handle hot water just fine. It's also possible to trick steam turbines into sucking 110C steam by keeping one of the inlets in a separate room with hot enough steam in it. If the hot room has very low pressure, you really don't need to give it a lot of heat, I even managed to create a stable system by giving 0.5g/s of water in a 2X3 room with a steel transformer in it, with two steam turbines on top. It's a pain in the butt to setup, but then you get a system that consumes virtually no power to tame a steam turbine.

HE USED AN INFITINE STORAGE OMG !!!1!11!!11!

Where was this yesterday when I needed it .
Guess I'll just have to try it again now that I know more about it. Keep up all the good work Echs

+ points for actually adapting your designs in such a way that it's easier to look at

10:44 You can block some of the turbines' inputs. That would increase the amount of time you have power out of the steam, spread out the gas pressure more evenly and decrease steam engine overheat...

Putting a little bit of liquid on the bottom tile of a Steam Turbine is a great way to keep it cool and help the cooling be conducted to it.

I had a leaky oil fissure spawned right next to the starting biome. I did have the wherewithal to keep it un-dug for 1500 cycles while I was learning my ways (first play ever). Later it turned out that those fissures don't get over-pressurized, so it would have just kept leaking and breaking my walls with that sweet sweet 270°C oil.

The danger of that heat is why insulated tiles and boxing in exposed vents/geysers ASAP is so high on my colony priority/research list. I've learned that lesson the hard way. RIP.

Very helpful info, Echo. Good stuff! Hope you and yours are having a good week. Best of wishes.

with the uncovered steam vent POIs, you might get lucky and have sand generate in the tiles above. in that case, you can do some strategic digging to drop the sand on top of the vent's active tile, quickly overpressurizing it. submerging the vent under an entire lake works, too.

(but most of the time i just end up rushing to seal it off with constructed tiles and scald half my colony.)

[MeHaveDonuts]

Awesome vid. These vents scared me so much when I spawned next to one that I made insulating my entire base my first priority and 100 cycles later I cornered myself into my own base surrounded by 100c temps with no way to access atmo suits.

[commonsense-oggz]

if you don't have access to plastic, you can control temperature in the vent area with liquid pipe looping. have a radiant pipe in the vent room, taking hot water out into large unused areas. obviously, this won't last forever, but it will be more value, then boxing them up.

[Rigr_Mrtis]

You can also add water to the 500°C steam to bring it down to 200° to be more efficient. I'm actually adding hot salt water from a geyser on my map to tame the steam geyser and desalinate the salt water at the same time. Might work with polluted water too if you keep the pressure hight enough to prevent off-gassing.

I know you have started a new beginners tutorial, but a lot of this is still relevant (and very valuable) thank you.

A couple of points.

1. Heat still gets through the top tile of your top tile in your cool steam vent tamer. This can be fixed most easily by just adding a 2nd layer of insulated tile. Perhaps also by building the vent 'room' 1 tile higher, but I haven't tried it.

2. The steam turbine is locked behind Applied Science Research. I wish I knew this before I attempted the build!

[SpottedHares]

If you’re willing to build big and dumb you can take the water from your colder geysers and send them over a cold block at the top of your cold steam geyser. Yea the cooling to water is more then the heating to steam turbine fuel but your not spending power to do so.

This dose have limits, but easy to over come. The hot water(97C) is great for oil and SPOM. And even slight warm water(over 30C) isn’t much of a problem for most none oil/SPOM uses, and for very sub zero water it helps avoid pipe bursting when purifying it.

[forethoughtx]

This game is so addicting. I just wish pressure levels affected sublimation temperatures in this game. It would allow different means of cooling ( like a rankine cycle of some sort).

[Lion]

About the cool steam vent: place a steam turbine ober the vent and run the exhaust of the turbine through 4-6 aquatuners that sit in the room with the vent. You'll get 5°C-35°C (depending on the number of aquatuners) warm water out of it while the heat you extract is used to bring the steam over 125°C and enable the turbine.
You can even snake the 5°C water behind the turbine to cool that down.

[joehelland]

minor correction needed, cool steam vents wear sunglasses.

[Abezy]

Vents are the bane of my existence in ONI seem easy till you start to mess with it

[cyrusmagnus]

This was very helpful. The game is very overwhelming.
