are you guys talking about this?

 

Yes! Just without the complex automation (why do you need an even spread?) and feeding Deoxys rather than Puffs.

An interesting idea.  It's also possible that instead of using a pitcher pump use a looping pipe what's one section designated to be emptied by a plumber.  As long as the pipe has a continuous flow a polluted water the plumbers job never ends and is constantly dropping bottles.  Use automation to restrict dupe access

Would you even need automation if you just used excess water? The PH20 would self-regulate their offgassing.

Any answers plz?

Here are my temperatures with water coming from a sieve at 39C.

O2 is approaching 34C, and the Pwater hits the deck at around 31C. So you need some temperature control. I started with these wheezeworts sitting in the open but I'm gradually moving them into more efficient H2 coolers.

Also since your sand use will be a lot higher this time around, another problem will compound this one: eventually you'll only have hot filter medium (either by crushing it in a granulator or by collecting regolith from the surface). One other thing you can do for temperature control. Use cooled filtration medium. Store it inside your AETN room and use rails for transport. Then you will have below-freezing clay dropping out of deodorizers (the clay seems to be created at the temp of your filter medium) [edit:this appears to be untrue]

Only if you keep the PW bottles separate from the deodorizers.

I mentioned earlier in this thread that deodorizers make tiny pokets of vacuum when they suck up PO2 (watch in thermal overlay) if the bottles are in this vacuum it will cause an off gassing loop that will exceed the 1.8Kg limit

And even if you keep them separate, deodorizers have no limit so they will keep producing O2 and overpressurize your base.

You'll need automation somewhere

This setup works like a dream for dropping pwater bottles:

Still experimenting with harvesting oxygen from it though.

Edit: Just had one bottle make it through, so might want to expand it by a door (or extend how long the door to the emptier remains closed for).

Main problem I've had is compensating for the athletic skill of the duplicate carrying the bottle.  

[Yunru]

I've not seen an issue. A few cycles in and there was 8.7t on the floor. Unless you mean them reaching the door before it closes. In which case... yeah, I got nothing. Maybe add a duplicant checkpoint when it becomes an issue?

 

Edit: So some of the time the door to the emptier just... doesn't lock O.o

Might be to do with the pulse being too short.

How much pOx are 8,7t off-gassing? I want to know if it´s linear with increasing bottleweight.

I believe that its 1% of the total per tick.

 

[Yunru]

I present to you, the Banhi system!

It's important to note that the bottle emptier across the chasm must have a higher priority than the one adjacent to the pitcher pump.

Also ignore the small pump, it's only there as a failsafe, and has yet to be used.

[Yunru]

Both bottle emptiers are set to auto-bottle yes, the one across the chasm is to get the dupe to drop the bottle, the one next to the pitcher pump is to get the dupe to return and reset the system. Obviously whoever has access to the emptiers shouldn't have access to the dropped bottles.

I shall defer to @Neotuck as to how to make this into a O2 system.

Is the offgassing also causing loss of mass in the water?

A few updates ago I tested offgassing in polluted dirt to the point of it vanishing - this wasn't a linear output, it was more like diminishing returns. I could not pinpoint at what value the substance completely vanished.

I really need to get into debug and a frame up a bunch of test templates.

The pWater looses 2,4% of its mass per cycle. I tested that with a 2t and a 4t bottle. Seems to be linear.

Thanks I'm sure I'm probably confusing linear equations and linear output.

It's a bit more complicated... sublimation equation is (mass^power_factor) * [1 or 1/5] = sublimation amount [ per second or per tick ]. You can take that and turn it into a percent per tick or per second if you like. But observing a single source, the percent decline gradually tapers off, because the base mass is decreasing by a factor smaller than what it originally started at. In other words, your g/s sublimation decreases with decreasing mass. You get the most output when you first drop the bottle, it's all down hill from there. So it's some percent, at that moment I suppose.

And you could probably use tables of known volumes of water for good emissions data, but then there's this issue below....

The per second emission, according to the information provided by the infor view panel, is inaccurate. I've verified this via debugging bottles of water and their emissions - calculating the exported masses after set periods of time - the numbers emission provided in the information windows are lower than what's actually being emitted. Which may have caused your colonial loss @Neotuck. It would be easy to get overwhelmed

The equation is mass*0.0000400000026 / 5 for per tick. Each time a tick is run, the value of the output changes, and though it might seem linear, it's not, it slopes ever so gently off as time goes by. @snoozer, due to floating point arithmetic, it's hard to nail down a series sum of such a small fraction of a large value without actually re-simulating the emission. If you want to know how much a given bottle of PO2 will off gass over a duration of time, I linked to a bug report with a python script  can figure it for you - it does just that, you just set the parameters at the top of the script and run it.

For instance, ~999kg bottle will actually emit 49.98g/s at that moment, but the information panel will say 42.7g/s...

This sim is running correctly, but the information it's giving us is ...bad. I've tested this scenario over and over and over again these past few days.

A 5000kg bottle will emit ~248g/s at the start, this decreases to 242g/s after 1 cycle

431g/s at the start.., after 1 cycle it will have emitted 206.31kg of PO2

The bigger the bottle the better, apparently.
