>>2236527>I've put way too much thought into it, but not seen anything made by anyone.The US Air Force has given this some serious thought since unloading in flight is a pain, and so has NASA, where the problem is much more complicated. Research contracts have been announced, you might try a FOIA to get some details.
>Most of my thought is how you would make anal tunnel plugs suitable for both urine and shit, without any leakage and without any backflow.It is important NOT to mix these two since poo is full of bacteria and urine is full of what bacteria considers "food", so the mix will make the bacterial activity go completely out of control. Urine is about 95% water, and if you can reclaim this water you save the pilot/astronaut even more effort. Much of the rest is salt and creatine, which also can be recycled. I could write a lot more but we are already a wee bit OT. Pic. related will get it on track again, right?
>I think the last thread was on /d/Not sure, I very rarely look through /d/, but I remember it was in the old /cyb/ general in /g/ a few years ago.
