ISS astronauts mimic nature to turn urine into drinking water

engadget 20 August 2015: Recycling water is key for astronauts on the International Space Station since sending water to the crew is heavy and expensive. The current systems work well and the tech is being used here on Earth in places where clean drinking water is in short supply. In an effort to increase efficiency, astronauts will test a new filtration system from Aquaporin Space Alliance. The so-called AquaMembrane employs nanotechnology and proteins to transform waste water (sweat and urine) into clean drinking water, proteins that regulate water in living things like human kidneys and bamboo shoots. Those aquaporin proteins are situated on a...read on.
