The thermal gas fissures seem like a really bad deal to me

[Gurgel]

Essentially you get 1t of Sulphur for 100kg of diamond and quite a bit of cooling. That strikes me as a really bad deal that I will probably not be interested in. 

[suicide commando]

You also get quite a bit of natural gas you can use for power, which then nets you some pWater. Still 100kg of diamond is quite a bit, so until you get a diamond press set up, maybe not something you want to do sustainably.

 

[MasterZenII]

Pinpokets from the abyss biome consume small amounts of refined carbon and produce diamond more resource efficiently than the press just slower.

[Mariolo]

It isn't as bad as it seems. You need 8 pinpoki per drill which comes to 40 kg of refined carbon per cycle. For that you get about 80 g/s of natural gas and 770 g/s of sulfur.

I still feel like the natural gas output could be higher. I wish it was 100 g/s to more closely match natural gas vents and be able to power a generator with 100% uptime. Keep in mind that the power drain on the drill isn't negligible.

I concur with @Mariolo. Running 8 pinpoki per drill is very doable IMO. Powering the drill is where things get costly. Running the drill for the 100 seconds it needs to reopen the fissure consumes about 130 seconds of its nat gas output. So in the end, you get about 68.6g/s of nat gas out of it. So yeah, all in all, you get about half a sulfur geyser and 65% of a nat gas vent worth of output for the cost of one wild arbor tree's worth of refined carbon and 8 pinpoki to tend to. If you compare it to a geyser, although very "mhe", it's a fair replacement. You basically get 15.5g/s of natural gas for a smidge of duplicant labor. (If it were to not cost you the spot of an other geyser, it would be very good though, but apparently, it does cost you a geyser slot.)

Typos. Way too many typos. I'm dyslexic.

I dont mind that mutch that it cost a geyser slot. I do get the impression with the introduction of various critter that produce metal ore that the dev are trying to move away from metal volcano (which can be a bit boring to tame; its always slapping 1 or 2 turbine on top of them).

I do agree however that the prize for running a drill on them seem lacking. I know that it could be very overpowered, but what if drilling those vent also yielded graphite? We find graphite on the water planetoid in space out, so it could make sense.

I second this.  Love the idea of replacing my water planetoid with an aquatic fragment

You know now that dupes can swim the water planet should be ez pz for grabbing graphite without suits. With the Breathing station dupe can be down there dam near all the time LOL.

So I want to revive the tread again because I really think that thermal gas fissure need a buff. While I think that they are at the very least a bit more interesting that a liquid sulfur and natural gas geyser (not better mind you, just different), I dont see much reason to tame more than one. Taming multiple fissures would be a very expensive project, requiring large amount of diamond and power, just to get more sulfur. At that point, we might as well establish a space mining operation for better resources.

However, if they could yield low amount of graphite, there would be an incentive to run multiple drills. Due to the large power cost, it would push player to expand power production (a common complain is there a lack of power sink in the late game). Also, it would encourage space travel since the starting asteroid only spawn a limited amount of aluminium.

The thermal gas fissure is meant as the start of the abyssal biome loop, not to throw off a bunch of resources by itself. It is active for 2 cycles (1200 seconds), then requires .2 cycles (120 seconds) to clear. This process takes 100kg diamond and gives 1000kg sulfur. On average it costs 45.45 kg/cycle diamond for 454.54 kg/cycle sulfur and 45 kg/cycle of natural gas. The natural gas is more than enough to make the system power positive. The sulfur can feed 22 tublia which is enough to sustain 11 glo squid - nearly a ranch and a half. Boiling the squid ink yields refined carbon which can be fed to pinpokets or used in a diamond press to get diamond. Either way, the output is 222 kg/cycle diamond - almost 5x what was required to run the drill.

I find the thermal gas fissure a bit boring by itself, but not weak. The loop is strictly determined. There's not another way to solve the abyssal biome without using the fissures and polluted brine geyser. Hopefully this will become more interesting as Klei develops critter morphs for the aquatic expansion.

Nevertheless, the abyssal biome as a whole is very strong. It gives plastic, diamond, and a +5 food source among other less noteworthy items; all possible without external resources or power. The biome even spawns in under 75 degrees so you don't need to build everything out of steel, making it accessible surprisingly early.
