Erasmus Crowley Posted February 23, 2017 Share Posted February 23, 2017 I achieved 100% sustainability. I got to cycle 130, but at this point there isn't anything left to do, and my base doesn't consume anything, so it can last forever. I got bored, and thought I would share how I did it. I rerolled my starting dupes until all three had the Diver's Lung perk, the Small Bladder weakness, and the Vomit stress response. First thing I did was build a pit to hold the coming storm of vomit and urine. After that I knocked out all the basic research. While that was going on, I was building outhouses everywhere. Each time a dupe would use the outhouse, I would destroy it. Each destroyed outhouse was a lump of contaminated soil laying on the ground. Contaminated soil generates contaminated oxygen, so thats how I kept my oxygen up. A few of my dupes got sick, but the sicknesses aren't lethal, and they wear off over time. Eventually, the dupes leveled up their skills enough that the decor wasn't keeping up and they started vomiting from stress. Once that happened, I took them to the top of my base and built the long hallway that you see in the image. I put the beds at the end of the hallway as lures. At night, because of the small bladders one (usually more than one) of the dupes will pee the bed. The urine then runs along the floor the whole length of the hallway. This creates a HUGE surface area to generate contaminated oxygen. With oxygen down, I created a big field of mealwood. I originally had it in the top/right corner of the base. It did a fair job of generating sustainable food. Don't cook it, don't refridgerate it, just put it in boxes. Cooking wastes water, fridges generate heat. It's not worth it. Just make more mealwood. I was stumped for a while on dealing with CO2. I knew that mealwood absorbs gasses, so I decided to build a CO2 trap at the bottom of the base and move a bunch of mealwood down there too. Turns out, mealwood will happily eat CO2 as it grows. So yea, infinite air, infinite food, and infinite CO2 management. None of it requires machines that generate heat, so the base stays nice and cool. I did build a water distillery, as you can see in the image. It works, but it was so slow that it was basically useless. It's a neat challenge though. If you use mealwood to deal with your CO2, you really don't need any water production though. I finished all the research and never needed water again. Link to comment Share on other sites More sharing options...
