TheScaryOne Posted December 28, 2017 Share Posted December 28, 2017 I would like to be able to collect liquids from a room passively without having gases pass, ie keeping a small room flooded with CO2 for slicksters and collecting it via gravity drain in a lower room without letting CO2 spill through. Should use raw or refined metal and plastic and not return plastic on deconstruct. Link to comment Share on other sites More sharing options...
Coolthulhu Posted December 28, 2017 Share Posted December 28, 2017 You can do it already. Build an L-shaped tunnel at the bottom, so that anything that wants to get in or out has to get through the oil. Link to comment Share on other sites More sharing options...
AlexRou Posted December 28, 2017 Share Posted December 28, 2017 I don't think there is any material in real life that allows liquids through but not gases. I feel like this is a little too fantasy, especially when you can use a liquid lock. Link to comment Share on other sites More sharing options...
AileTheAlien Posted December 30, 2017 Share Posted December 30, 2017 Just build a liquid pump at the bottom. It won't pump air into pipes. Link to comment Share on other sites More sharing options...
