Clean and easy to use, the envisioned space toilet is designed to be worn like a diaper around the astronaut’s waist at all times. Sensors detect when the user relieves him or herself, automatically activating a rear-mounted suction unit that draws the waste away from the body through tubes into a separate container. In addition to washing and drying the wearer after each use, the next-generation space toilet will incorporate features that eliminate unwanted sound and odor.Sure, you could do this. Or you could re-engineer humans for space such that they wouldn't need to wear these ridiculous hi-tech space toilets. That's why the concept of cybernetic organisms was developed in the first place; cyborgs don't wear diapers.
