Yep, you can do all kinds of fun stuff there. My critter drowning chambers consist of a little pool of water that the critters occasionally walk through. If the room sensor detects that the room is crowded, and the pool sensor detects that a critter is in it, the doors close until the critter has drowned. The door opens again and the autosweepers pick up the meat.
This is the water system I mentioned earlier, screenshot is from quite a few cycles ago. I quite like the bathroom design - dupes enter through the top door, do their business, go downstairs, and wash up before leaving. You can also see my first Hatch ranch.
From a few cycles later, I am having unacceptable heat issues due to the geyser, so I have begun insulating it. I am also going to make use of the water - so long as it is below 70 degrees, it won’t warm the output any more than the oxidation process itself.
A handful more cycles down the road. Hydrogen is becoming a problem, so I am making a big cavern at the top (carving away softer materials) to store it in. You can see I am renovating my farms - I end up rejecting that design, and making a new one. To avoid starvation, I keep the existing farm until the new one is ready.
Up to date photo. I am designing these farms with automation in mind. I already have some tweaks to the design, but for now I will leave them be. You can see I am also harvesting that hydrogen now.
You will also note I have dug out the teleporter room, and can see that it leads to ‘an irradiated world with renewable water sources’. I think I want to explore it, perhaps by cycle 50. It has acool slush geyser!
Things are going pretty well in my base. I’m sending a dupe over to the other asteroid to get some cool slush, because with that geyser nearby heat is becoming a serious issue. I also have a lot of oil to tap, so cooling will be fantastic.
I got a dupe out of the other world, so I’m up to 13 total now. No cool slush geyser in sight, so we’ll need to get set up with a temporary base while we explore. For now, I’m thinking I will set up a minimalist facility to tap the cool water and bring it home. Later I might set up a fully functioning base here.
ETA: A few cycles later - my current base on the second asteroid. My plan is to drain all the water into a pool at the bottom there, leaving plenty of open space for the pips to roam free until I can understand what they are for. On the right is where I suspect the cool slush geyser is, so I shall be digging that-a-way.
