The building is unlocked from the start. You can find it under the Py Fusion Energy tab. It can only make vacuum recipe to begin with, but Coal Processing 1 unlocks making pressured air.

I am playing with the full py suite and I have researched oil processing. However, I see that pumpjacks require niobium. That seems odd to me, as that means that researching this tech doesn't actually allow you to start using oil. To get niobium, you then further unlock sulfur processing, then desul...

Since ammo now requires lead, and mining lead requires acetylene, there is quite a long chain of products to get going before you can make any ammo at all. The time spent, and more importantly, the pollution generated to get any new ammo basically guarantees that I have already fended off enough bit...

Enabling steel at the beginning does fix the deadlock, but making the Automated Screener building is a bit of a shocker in required materials so early in the game. It needs 60 steel + 120 iron plate, which means processing 7200 iron ore - far, far more than any other early building. Perhaps consider...

Is there any disadvantage in using wrought-iron pipes instead of normal iron pipes? Like less maximum flow? Or are they the same?

Ran into a deadlock with latest py mods. To get science pack 1, you need glass, which comes from quartz ore. There is a recipe to create quartz ore from sand, but it seems to be only craftable in an Automated Screener building. That building requires steel to build, which can't be unlocked without s...

I'm excited to really dig in with this. I'm glad you cut back on the number of spawned resource islands. I think a few are fine both for a little variety and to experience some of the benefits of later technology. I noticed a (minor) exploit with it so far: you can make a wrought-iron pipe, place an...
