Food production is still quite low, and I've made more than a few mush bars to keep up with my 8 dups.
All we need to beat carnivore & locavore is get a few more dups and keep running the hatch & fish stables manually. (Around c45 we'll get mechatronics, which will help.)
So. Now what? Well, super-sustainable. We need h2, and lots of it. I propose to build two 2-submerged-electrolyzer rigs. That's way more o2 than we'll need until the endgame, but we need the h2.
