I did not check the math, but you should probably also account for the time it takes for the lumber to get to the distilleries.

I don't think that this is a rounding error. I have had dupes trying to stuff 100s of kgs of additional oxylite into rocket tanks, which would just be rejected and fall on the ground at the rocket's foot. I was not using jet suits, so my solution was to just retract the gantry. It's a bug, for sure, but I suspect that it's some other kind of sloppy programming, not rounding.

This is not the bug report section.

Last I checked, this is not how generators work. If you don't hook up any automation to the hydrogen generator, and attach it to a battery, it will just burn off everything it receives (unless something was changed very recently).

I know that this is not what you are asking about, but cannot resist pointing out that this is somewhat backwards logic. You do not need to artificially create load on the circuit to burn off excess hydrogen. Just have a simple bridge-based overflow that goes to a hydrogen generator that is not connected to any automation, so that it runs every time the hydrogen backs up to the bridge. This way you can at any moment decide to e.g. create more gas storage tanks behind the bridge to start banking for your rockets (eventually it will be the hydrogen that you will want more of, and you will be looking for ways to get rid of excess oxygen), and the overflow will still work. This should have nothing to do with your trying to waste energy on cooling water.

In fact the pumps are also a waste of power. There is no functional difference between this setup and producing the oxygen right in your base and having 3 wheezeorts there. The only difference is that this way you waste 600W. Edit: ..., not to mention precious dupe running time.

You do not need to pipe the CO2. Over time it will automatically sink to the bottom, so just placing your scrubbers at the bottom of the base should be enough. For cooling: I tend to cool my (base) oxygen near where it is produced, rather than separately cooling the base. Note that you usually do not need to cool the atmo suit oxygen. As far as overpressurised oxygen is concerned: just don't let it overpressurise. If you pipe it into the base from your production unit and distribute it through normal vents, then they will never get the pressure to more than 2kg per tile.

My past experience suggests that the AETN will not quite keep up with the heating from the water (despite insulated pipes, unless they are made from insulation, they will slowly heat up), and the cold biome will slowly melt (you can already see it, the water that is gathering at the top will keep coming). That should be ok, you will get a good several hundred cycles out of this. Just make sure you set up your power unit that powers this thing in such a way that it cannot get flooded. If/when you get atmo suits, you could send the oxygen from the top pump directly to the atmosuits. It won't be as cold, but the atmosuits don't care, and this will not decrease the flow rate to your base, it will really be extra oxygen.

It's nice, although after a while the electrolysers will be running at less than 2/3 efficiency, because they will overpressurise: the two electrolysers together produce 1776 g/s of O2, but the two pumps only pump out 1000g/s. I see that you already have automation connected to the pumps, so when you feel that you need more oxygen, you can safely put 4 air pumps at the bottom, and have the automation switch them off before the air pressure gets too low, to avoid getting hydrogen at the bottom. And from there, you are not far away from the by now classical build that does not use a filter, and instead uses the properties of the gases and the ONI gas mechanic to let the gases separate automatically. That would save you 120W, and should be self-powering, even with the AETN (it produces excess energy without the AETN).

You are making quite a big deal out of this. Just have a buffer tank in your cooling loop, like Steve Raptor said, and don't fill it up completely. Of course, you still can break it by completely filling up the loop and the tank, but if you are not actually trying to break it, it will just work. I just disconnect the coolant supply manually when I am happy with my loop, but if you really want to automate it and leave the supply pipe in place, then put a liquid sensor in the last segment of the cooling pipe just before it loops back to the supply point (I would connect the supply to the in port of the buffer tank, and then place the sensor on the last segment of the cooling loop before the coolant comes back into the tank), have a liquid shutoff in the supply line, and deactivate the supply when the sensor detects any liquid. You can fill a bit of the buffer tank by either inserting a delay buffer gate in the automation or having the shutoff further down the supply pipe. Having some extra coolant in the buffer tank helps stabilise the temperature of the coolant.

Wow, one does not encounter such a hostility very often on these forums. Not sure what you guys have been smoking, but you better lay off that stuff. All I was saying is that if you have heat to delete somewhere (which I am assuming, because otherwise we don't need to have this discussion), then feeding 30C water into the electrolyser is not the way to do it. Instead, pipe it around, let it soak up some of that heat, and delete it in the electrolyser. This costs no extra power. As for these nightmares you have been having about steel, or sourcing 95C water, or excel: as I say, lay off that stuff you are smoking. 'Cause whereever you got these fantasies from, it was not from anything anybody here said.

I will be that someone. Water has a much higher heat capacity that oxygen, so it is much more efficient to cool the air after it comes out of the electrolyser than cooling the ingoing water. By pumping in cold water you are foregoing the heat deleting capacity of the electrolyser.

And while we are at it, I also wonder what will happen to "No More Oxygen For You", to "Oxygen Costs Extra", and to "Do I Look Like Santa Clause To Be Giving Out Oxygen For Free? Go And Find Your Oxygen Elsewhere". Serious questions.

I cannot resist:

Thanks! But now I am even more confused: wouldn't insulated insulation prevent all heat to be exchanged between the hot content of the pipes and the pool? Could one just melt the pipes on purpose by making non-insulated pipes out of insulation and get tungsten this way? Then would one still need the insulation tempshift plate?
