my cool new cool steam vent harvester design!!

[kingjames488]

at least I think it's new, I've never seen anyone do this before.
I'm once again pretty excited about this!

BAM! harvesting 109C steam.

apparently the steam turbines only care if steam above 125C exists in a tile below them, they don't care if all the steam is that temp... so feeding hot steam to one tile allows them to suck up cool steam on the other 4! XD

unfortunately I made the steam chamber slightly too small and it over-pressures just a liiitle bit(though not to the point of stalling it out, just losing a little potential steam)... this should be able to extract 2400g/s which is well over the average output, but ya...

that thread seems to be talking about the same idea, but none of those designs are quite the same?

they seem to be using the method to create 2 chambers and then using the cool side to cool something(which is interesting don't get me wrong) whereas I'm sucking up the cool steam directly from the geyser... not sure what method is better, I'm not seeing anyone infinitely storing a cool steam vent without condensing it though.


and I figured I'd need a room with 80 tiles of space to deal with the over-pressure without any of the steam condensing or needing pumps which would mean it would need to be 2 tiles wider and 1 floor higher so not totally unreasonable.

I would have never thought to place a steam turbine right on top of a vent. Thank you for sharing.

it's actually slightly off to the side of the vent :P

Now this is really interesting, I would never have thought of this.
Can I get a screenshot of the pipes? As far as I understand, half of the steam goes into the tank and the other half goes to cooling the aquatuner?

(sorry for the clutter, bunch of un-related piping around)
not quite, the top liquid vents are hooked up to the atmo sensors to open if the pressure is below 20k kg and the pipes simply bypass them so when it's not feeding back into the chamber it's going into the tank.

the hot steam in the aqua tuner area can be super-heated to at least 300c since it's only going to one of the turbines inputs so the only realistic limit on the temps there is keeping the aqua tuner from over-heating. I also have the aqua-tuner limited to not run over 300C to prevent it from frying it's self; though it was mostly just needed for the startup and once running it seems to be able to cool the hot chamber enough to keep things from over-heating with the aqua tuner running at 98%+.

[Fluffle Puff]

Thank you! This is really impressive. Brilliant solution. Now I will master steam funnels only by this method.

[kingjames488]

also the automation on the steam turbines is just an atmo sensor in the geyser cxhamber and a thermo sensor in the hot chamber so they run when the geyser is erupting or if the hot steam is getting too hot to keep the aquatuner cool between active periods.

From the wiki at https://oxygennotincluded.fandom.com/wiki/Steam_Turbine

"For the steam turbine to function only 1 port requires 125 °C. Therefore it is possible to create setup where a steam turbine accepts steam from 2 steam rooms where the temperature of one steam room is at 100 °C and the other above 125 °C. This effectively allows you to cool a room to 100 °C."

ok, so I independently re-discovered this... I still wanted to share my build thanks :)

It's a very nifty build! Plus it's pleasing to look at. Just leaving this info here in case it helps anyone -- a quite convenient way of taming a cool steam vent is by geotuning it at least once. That pushes the steam temperature to a temperature that is usable by the steam turbines directly, making it a very efficient way to tame it.

thanks!

geotuning is also an option, and can be really interesting with the hot salt water geyser(1 geotune makes it put out salt and cool steam, 2 and it can run a turbine IIRC). But I don't really trust my dupes to keep the tuned up lol.

[Molay]

I find it worthwhile to print a dedicated researcher for tuning tbh. If you tune a default salt geyser 5 times, that's about 3kg/s of extra salt water. That's oxygen for some 24 dupes or so, or anything else you wanna do with the water. Definitely worth to feed an extra mouth just to keep tuning it up :) That's assuming you can satisfy the salt/gold for the bleachstone hopper. If you have one or multiple chlorine vents, pufts are really useful too. Oh and it's also power positive :)

[kingjames488]

for some reason I never seem to have an abundance of gold for making oxylite or bleachstone >.<

[Molay]

Ah I see. I play mostly on moonlet cluster, and there you have at least one guaranteed gold volcano, but usually 2, and not infrequently 3. That said, you can raise bammoths now for gold! Their crest is worth a whopping 50kg of gold, so one shearing already nets you 1 ton of bleach stone if converted via the hopper! And one geotuner uses on average 15 kg of bleachstone per cycle, So an average gold volcano is enough for some 66 geotuners, which is quite a lot of water geysers to have in the first place|^^
