A Swedish industrial designer, inspired by a project with NASA, created a shower system that reuses the same water in a circular loop, while two filters take out impurities as it circulates.

Mehrdad Mahdjoubi realized the parallels between sustainability in space and on Earth when he was working on an academic project for NASA.

“The reason that we make it work sustainably in space is because we have to do it,” he told The Guardian newspaper. “What if we try the same things on Earth … [if] the house was like a space capsule, how would we go about it?”

His “Shower of the Future,” can operate on 5 liters of water.
