3. Space Toilet: Lots Of Student Debt
How could we assemble a list of high-tech toilets and not include the one that astronauts do their business in? Well, don’t worry, here it is. The space toilet is also known as the zero gravity toilet since it can be used in weightless environments.
The space toilet borrows from a couple of our previous greener entries. Not totally unlike the KazubaLoo, airflow plays a very, very important role here. The aforementioned airflow directs the solids and liquids where they are exposed to vacuum conditions to kill off the bacteria responsible for odors and pathogens. And like the Loowatt, waste gets compressed and bagged up until they land back on earth. Previous models used to shoot waste water into space.
The air used in these toilets gets cycled back into the ship during a mission. So, needless to say, they have some pretty crucial filtration systems out there.
