This wall separates the space in 2 to clearly delimit the "pee/input" part and the "water distribution/output" part. The wall contains a high-tech filtration system with a large storage capacity. All of this works without electricity and can therefore be used on Mars (or the moon).
It is completely free to use and the wall will be covered with targeted advertisements on both sides to earn money, naturally
clarification: this project is obviously a joke!
