As the title, how did you guys solve the issue with gold, hot steam and stone? I am currently wasting a lot of energy in creating wood with that bacteria and burn it...
Perhaps my expectation where more like Vanilla Vulcanus and this mod its not like that :P

Also, what do I have to do with that much Acidic water?

I agree, I had to built an immense and overcomplex network of factories to make Vulcanus self sustainable; definetly too much.

Probably the best thing to do is to make a small outpost, make the basic science on Vulcanus and Gleba develop asteroid processing and then supply with ice and uranium using space harvester but i don't like this approach and i think that forcing a player into a forced path make all the modpack less enjoiable.

By the way discounted of this problem i appreciate the mod. Thank you for your work.

Slag from casting and the various outputs of the Excavator which include stone and when otherwise are processed allow for all exotic materials to be locally created and ergo for High-redox acid neutralisation recipe to generate 500c steam.

Acidic water can be channeled into Sulfuric acid which can be used for material extraction from slag.
