Early O2 Farm (cycle 30)

[Neotuck]

I started a new survival and was looking for a way to extend the life of my algae supply and get the most O2 as long as possible, this is what I came up with by cycle 30

Here's my math:

There are 12 algae terrariums that use 30g/s algae each for a total of 360g/s  (Algae Deoxydizer use 550g/s)

With light The terrariums emits 44g/s oxygen for a total of 525g/s (Algae Deoxydizer emits 500g/s)

The terrariums drop polluted water bottles that emit polluted oxygen and while nearby deodorizers will quickly become clean oxygen

The rate in which the PW bottles emit PO2 depends on how full they are, the one's in the pic are about 660kg and emit PO2 at 27g/s avarage

That's a total of 300 to 330 g/s oxygen produce from the polluted water bottles/deodorizers alone

So to summarize I'm getting almost 800g/s oxygen for 360g/s algae 

only problem is terrariums don't have an over pressure option so I have had to automate it will doors (atmo sensor set to 1500g)

This works out even better as I can save up algae and water as I get most of my oxygen from the dropped bottles

With 6 dupes the downtime seems to last about half a cycle so if I divide the O2 production from the terrariums in half I get:

 

Uses 180g/s algae average

Uses 1.8kg/s water average

Emits 600g/s oxygen average (good for 6 dupes)

 

 

Just for reference here's a pic of my whole base

That's a nice setup to use the algae terrariums.

But if I understand it well, it consumes more O2 than electrolyzers ? It's nice to use at the start when you're low on algae in the starting biome but you need a lot of water if you want enough of it to tame a cool steam vent before you run dry.

[crypticorb]

Well done.

Something you haven't accounted for: sand. The deodorizers use sand to convert pO2 to O2, but since sand is all but renewable, and regolith is renewable, this isn't terribly important.

One other thing of note is that this would require some basic automation, which requires Brute-Force Refinement, Automatic Control, and Improved Ventilation researched, so cycle 30 is a bit optimistic if you are a newbro.

The water consumption is a bit costly when compared with an electrolyzer, but it's essentially a no power replacement for either the algae deoxydizer or electrolyzer, and can be accessed very early with the right research.

true I had to rush the research to get it by 30, this would more likely be a cycle 50 solution when algae becomes scarce

This is not a replacement for electrolyzers, more of a step between deodorizers and electrolyzers.

And I don't think I'll have to worry about water anytime soon...

This alone is worthwhile, since it took me 100 cycles to get my butt in gear and make a proper electrolyzer setup due to how complex I like to make them.

...I still haven't finished with my electrolyzer setup, and it's cyle 468...

haha I often find myself looking for fresh tiles of algae to dig out before I can finish my own electrolyzer setup

I'm not a fan of most S.P.O.M designs as they confine the electrolyzer in order to separate the hydrogen without filters, but that causes it to over pressurize easy resulting in efficiency loss

before building my main electrolyzer setup I plan to just place 1 inside my base surrounded with wheezeworts, not that big of a deal to let hydrogen pool at the top of my base

[Lifegrow]

Just slap uncooled electrolyzers outside of your base and give your dupes some stuff to do

By the time the heat from the electrolyzers has even remotely started to have an effect on your base, you'll be in a position to turn them off and get your main build online.

I regularly limp to cycle 300ish on algae alone, so I don't know if an "intermediate" step is all that necessary most of the time.

sounds like a good idea, might do that with the steam vent outside my base

I wonder how far I can limp on algae alone, I just reached cycle 60 and still have most of my algae from the starter biome

I'll be running out of water soon so I'm making preps to sieve nearby PW pools

[Neotuck]

Well I'm now I'm over 100 cycles and here's an update

O2 production going strong, my Algae count is over 21 tons (most of which is still from the starting biome, the rest was picked up as I gathered slime for my mushroom farm)

Starting biome water almost dry (no supersize there) but I'm ready to start sieving PW pools found in the slime biome, I have already sieved one

currently working on my 6 type limitless gas storage system....

Glad to see you're having similar results to what I've seen in the past when I've done stuff similar with Terrariums.

Lots of players claim algae terrariums are not efficient enough to be worth building, I plant to prove them otherwise

Yeah. They definitely have a place in early bases and can supply decent sized bases for minimal power and only occasional dupe interaction. 

Out of curiosity, is there a reason for dropping the polluted water under the Terrariums with the doors instead of "flooding" them so that the dupes only have to empty the polluted water? Or can you not water them by flooding them anymore?

It's not for dropping bottles, it's for "turning off" the terrariums to prevent over pressure in the base causing popped eardrums

Gotcha. I missed your earlier comment when I skimmed this at work. Thanks.

It's not so much they're not good, they're just not necessary in a lot of cases. Once you've played enough games to get your early plan of attack sorted, you can kind of bypass any early O2/CO2 issues with ease.

My favourite use for terrariums used to be when digging out biomes far from home, or heading down to oil, etc - but now we have the gas cannisters/emptiers, they're kind of superseded for that too.

I don't think anyone's ever said you cant get by with terrariums alone... hell, the Klei devs do it on every sodding dev stream

It's a dated opinion from before they produced P-H2O.  The fact that they are now mass positive makes them significantly more useful through the early and mid game.  It's mostly a question of whether you are willing to dedicate a Dupe to managing the Terrariums through that part of the game or not.

I had thought about that but wondered if it's worth it, dupes seem to only carry 10kg canisters at a time, seems you get more out of the terrariums with just a single trip of water and algae (depending were you are algae may not be far away)

[Lifegrow]

If you're making just a little breathing room/checkpoint, 10kg goes a long way.

[Neotuck]

a fair point, also think about cost, you need 200kg refined metals for the emptier 

might not be available if you are doing early game exploring

I can vouch for this. 

[Neotuck]

BTW @Lifegrow I have an off topic question

Where and when can I see your live streams?

I have been subscribed to your Youtube channel for months now but the only notifications I get are when you upload the 30 min recordings of your streams (sometimes out of order)

I would like to be there next time you go live

[KittenIsAGeek]

From the perspective of resources, algae terrariums are the most efficient methods of producing O2 in the game.  You can minimize dupe travel times by letting water flow over the terrariums and using automation to deliver the algae.  Also, by keeping the polluted water bottles, its easy to use them to set up PO2 production -- though, that reduces their resource efficiency.  You can also use algae terrariums to feed Dense Pufts for producing Oxylite.  Because the terrariums can over-pressurize the room, you don't have to worry about the oxylite sublimating before you can collect it.

Good job on finding a method that works for you in your base.

[SakuraKoi]

I personally prefer to submerge my Terrariums in water, it saves a lot of time. Of course the polluted water shall be emptied right next to it, pumped into a Sieve (one can accommodate 17), through one or two Aquatuners (periodically, I like two) and et voila: Lots of clean cool water for blossoms.

 

Since my current colony has a tad too much water I go with Electrolyzers thou', the boons and bane of a custom map...

Come find me on Twitch bud (https://www.twitch.tv/lifegrowski) schedules in my channel info.

Also, Youtube doesn't handle bulk scheduled uploads very well, so as I use it for a, well - a raw vod backup area, you're best to click the playlists to get the vids in order.

This was an excellent read. Thank you, @Neotuck.
