Arbor Trees for cooling! - Oxygen not included

[@Luma_plays]

Thanks to Uilson from the Discord server for the help and additional Ideas. Hey Guys. I used the fact that Arbor Tree Branches grow at a fixed 25°C to cool down stuff. In short: Tree branches grow at 25°C but hate full tiles of liquids so they get destroyed once they reach it. But they absorb the heat of the liquid tiles first. So -> heat deletion.

[@Paperbag34]

It never ceases to amaze me all the kinds of ridiculous, amazing and brilliant _bullshit_ the ONI community can come up with. I can't believe this is actually a semi-viable cooling solution, this is absolutely hilarious. I hope Klei doesn't change this, honestly. This is just hilarious.

[@recer7506]

I must agree. The funn of ONI is finding all the litle triks that make the game just a bit easier. Now i want to play ONI agein, but i know it will occupy me for the next 3 months if i start a save.

[@darqhalo9004]

The amount of effort to get this going is hopefully enough to make this a feature and not a bug. AND that BS callout 🎉👏👏

[@nazgu1]

That said, this is by far the trickiest cooling setup I've ever seen. If you already have trees, I think it's much easier to setup an ethanol boiler to cool an aquatuner, which can then provide cooling wherever you need it.

[@Tamizushi]

I've made worst. Bypassing the mine 125 celcius steam temperature by feeding 0.5 g/s of hot steam to a single steam turbine inlet, leaving 3 inlets to suck cold steam (a 5ft inlet blocked by an insulated tile to keep low pressure hot steam separated from higher pressure cold steam). Boiling polluted water. Using a heat exchanger to cool down the outgoing steam with the incoming polluted water. Then using the "hacked" turbine to put the steam into liquid pipes as water. Using that warm water to preheat the pdirt. It was all just an excuse to boil pwater using the minimum possible amount of heat and without spending any power. Everything was working on minuscule temp ranges, it was very unstable. Wouldn't recommend. The finickiest part of it was that after self-cooling, the water coming out of steam turbines was about 95.5 to 96 celcius, but pwater needed to be at least 96.35 celcius to avoid condensating the cold steam coming out of the exchanger. I spend way to long trying to give the very minimum amount of heat to it so the whole things doesn't break. There whole system was balanced on a needle.

[@ulasuncu5721]

That is the worst cooling system in the game, probably better to just use ice makers. If you have arbor trees and ethanol, the better cooling method is to use aquatuner to dump heat into the lumber before it is destroyed. You need metal tiles to provide decent heat exchange. Arbor trees give 500 gr/s of lumber and if you have 4 trees and add 20 degrees of heat into that lumber before destruction that is quarter of the capacity for a water-based aquatuner. Heat it up by 40 degrees and that is an aquatuner with 50% uptime cooled by lumber only. You can also store some lumber and increase capacity whenever you need it. Unlike the ethanol boiler, which provides something like 10% cooling of the capacity of the aquatuner, all the power you put into this system will go into net cooling.

[@nightbot6415]

Wow, this is definetly something i will use in my current Base. I already got many arbor trees, so this will be the perfect addition to my cooling system.

[@pikolino210]

Teacher: "Use an aquatuner to move heat from A to B" That weird student: "Nah bro I will be cooling stuff with tree branches"

[@Luma_plays]

XD made me giggle

[@downey6666]

This is a challenge to build without sandbox -- guessing you start with a complete vacuum box - and since its vertical - use like a run off method to stack/drop the liquids from a tap

[@Luma_plays]

Yes i think it would be challenging in survival. I would try to use exact measures via the liquid meter valve. Then you need to get a pip to plant the seed or the other way around what fits you best. the natural tile can either be created or be planned beforehand.

[@downey6666]

@@Luma_plays Think this is going to be perfect for an early game plastic to sour gas boiler --it can condense 550c sour gas down to 150c methane without a massive power draw

[@SpencerUnderwoods]

According to Professor Oakshell's Cooling Calculator, cooling 1 KG per second of Hydrogen from 500c to 140c is ~864,000 DTU worth of cooling, or about ~144,000 DTU of cooling per tree, or about the equivalent of 12 domestic wheezeworts. I know Arbor trees have always been possible to use for heat deletion by dumping tons of heat into lumber on rails before burning it, but doing so isn't quite as efficient as this (estimated hydrogen output would be ... ~250*c, ish?) and is definitely more complex. This you can just about plop down anywhere for easy cooling, as you handily demonstrated cooling down steam turbines! Great find!

[@Luma_plays]

Cool thanks for the math. Will try to see if that can be used to calculate the cooling peoperties. Thanks again!

[@rainerplays]

Nice find! This seems like a great way to passively keep a base cooled at 25 degrees. With the minimal heat that is typically produced inside, 1 tree might already be enough...

[@craigmccune6066]

i wuld prob still use 2, but thats for just in case

[@azrobbins01]

Great ideas! I am amazed at how many ways there are to do things in this game.

[@nazgu1]

There is a known heat deletion method for the wood produced by the trees, and harvesting branches via water falls is also an old trick, but this is the first time I've seen heat deletion via branches. Neat! :)

[@rustit]

Outstanding! Will use in my next base. Thanks!

[@HilaryCheng]

It is crazy. You are always find new way to make new fun!

[@PoringPoring951]

Amazing how this was discovered and the method to get around the livable range of the tree. But this does not seems to be the intended way. Most likely patch incoming.

[@Luma_plays]

I tried to come up qith a quick seed producing method for the pacu and someone suggested the arbor tree seed farm (Originally from Fradow as far aa i researched) but then we noticed, that pacu no longer eat seeds feom every plant. Only specific seeds. So I unlisted the video. But we noticed that the Temperature in our setups was stable and triwd to immediately use that for cooling. After a bit of testing this first crude setuo came into existence. I don't know if that already has been discovered as a cooling method and if klei knows about that.

[@AlexanderBukh]

why patch, tho? it is not really op, and fiddly enough to stay as it is. then again, how exactly you see it patched? sharing temperature branches to root? then it can be used as a tempshift plate substitute, ahahah

[@Luma_plays]

@@AlexanderBukh Haha good thinking. Fixing it will only give us another thing to use

[@Tamizushi]

Very cool. I think it's worth mentioning that if you can use self-cooling to supplement another form of cooling, you probably should, as it recycles the aquatuner's heat into the steam room, increasing the overall system's efficiency.

[@DrDoktor60]

You can also use gulp fish for cooling 😊

[@travisperkins9920]

I used a gulp fish/carbon skimmer set up and almost froze my base by leaving the running. Seriously gets cold if you leave it running for too long without managing it

[@DrDoktor60]

If you put the dropped lumber on conveyor rails and drag it through the metal tiles you could draw out even more heat. If then input into distiller you destroy heat even.

[@Luma_plays]

That is true good catch. Though we do not get any lumber from this setup. At all. you could leave the top tile unblocked to get a bit lumber every ?18? cycles i think. Not sure that is worth the conveyor rail materials.

[@robotnikkkk001]

​@@Luma_plays.....CONVEYOR RAIL MATERIALS, YESS...... SO NO WAY BEFORE GETTING NIOBIUM AND TAMING ALL THESE ON KILLER TREE ASTEROID, INDEED ..........BUT STILL...........DEFINITELY SOME CONCEPT OF DOMESTIC SETUP MUST VE BEEN INVENTED......

[@thesentientneuron6550]

I came in here expecting an ethanol burner type cooling system based on the title but boy was I surprised, you did not disappoint. This is legitimately cool Luma! Perhaps you can experiment with a thumbnail or title that _branches out_ to more people? (Sorry, not sorry, dad jokes da best).

[@Luma_plays]

Haha i think most ONI players are at least in Dad age so you hit the spot. I am thankful for every title or thumbnail idea. That is the part i like least about doing youtube.

[@Chikithulu]

Hydrogen vent tamer just dropped

[@iluria902]

One question, isn't it more efficient to use the hydrogen temperature to heat the steam and cool it with the turbine? But, could this arbor tree system be used to cool the base, or like a steam cool vent or salt water geyser??

[@Luma_plays]

The Hydrogen was just to show the cooling power of the Trees. Since i didn't know how powerful it could be. It is of course better to always use the heat to the max. before cooling anything

[@MarkkuS]

I want to put one in the base to keep it at perfect 25c

[@Grin-TLT]

Hi. Hast du zufällig ein Guide oder hast in Lets Play vllt schon gemacht, wie man ein Meteor Protection System mit bunkerdoors bauen kann ? Damit man gleichzeitig noch Raketen benutzen kann ?

[@Luma_plays]

Tatsächlich noch nicht; ich spiele hauptsächlich DLC und da gibt es nur bei manchen Planeten Meteorschauer. Ich hab aber bei den Update Videos ein Meteor Blaster System gezeigt. Falls das hilft schau da mal rein. :)

[@austinglander1337]

How many joules of heat are deleted by one tree at various temperatures? How does this compare to an aquatuner?

[@Luma_plays]

We would also like tp know. I Don't know yet. Nobody wanted to do the math me included. You have the mass of the branches their conductivity and the often random times they grow and all the different material conductivities and mass. Sounds like alot of variables

[@austinglander1337]

​@@Luma_plays A lot of variables for a theoretical calculation, but why not just do an experimental one based on your data for 100 cycles? You know the volume of hydrogen moved and the temperature change, so you should be able to calculate how many joules were removed from the hydrogen. Then just divide that number by how many trees you have and the amount of seconds in your experiment and you should have a fairly accurate value for the heat deletion of each tree in Joules / second. The only quirk I can see is that the amount of heat deletion depends on the hydrogen input temp (greater heat deletion with higher temps), so you'd have to repeat the experiment at different temps to tabulate these values.

[@LilithG-zl1gs]

Could this be used to tame a CSV, I wonder? That would the EASIEST thing possible, I want to try it.

[@Luma_plays]

I think yes. Someone in the discord build something like that. But i haven't tried it myself

[@atTran-ng1df]

you can now do it with bonbon tree

[@Luma_plays]

Yes

[@atTran-ng1df]

@@Luma_plays i've just discovered that bonbon tree branch spawn at a fixed -18~-19C, at 8kg with 3.47SHC. take 25C at the desired temp, with perfect condition, a branch delete (25+19)*8000*3.47=1.2 M DTU, compared to 10kg of supercoolant which running through an aquatuner only delete ~1.18 M DTU. the setup is pretty simple just get bonbon tree to a vaacum, use mercury to drown the branch as mercury has a 8. of thermal conductivity which is perfect to drain the cooling off the branch and a mechanized door to control the cool

[@pr4130]

how do you get the vacuum in the middle, i mean how to build it step by step 🤔?

[@Luma_plays]

No clue this was a proof of concept done in Sansbox. You can either plant the tree first and then vacuum alarge room out then drop the liquids. or first the liquids and then plant the tree. the rest can be build afterwards

[@mohddinzakaria1448]

So u need to vacuum the tree...😂 My tree died when cooling 🌋

[@Luma_plays]

Yep the crude oil in the lower tile acts as atmosphere. That is disconnected from any heat transfer. the middle tile is vacuum the rest transports the heat around.

[@larsidkoiwak5742]

And how do you build this without sandbox mode?

[@Robin93k]

Good planning, Pips and Water logs. The planning part is just keeping dirt (or any other plantable tile) around. Pips to plant the Trees. Waterlogged entrance and Air Pump to create the Vacuum. Then just build it layer for layer.

[@linuxgaming69]

I could not be arsed.

[@arigatoespacialsuperadmiti7316]

It makes me somewhat mad ther aren't more options for cooling other than steam turbines and ice fans. Ther should be other similar options like the thermo nullifier but buildable

[@Luma_plays]

The cooling options are quite limited. Not even a deep freezer in an asteroid world with a human printer seems weird. For cooling you can also use the wheezewort. But that is pretty much it.
