The new system not only filters water, but also takes the leftover waste and uses it to generate energy. According to Science News:
“To pull pure water out of urine, the system uses forward osmosis, which, as the name implies, works in the opposite direction of the reverse osmosis systems found at many kitchen sinks. Forward osmosis uses a concentrated salt or sugar solution to draw the water out of urine. Next, enzymes in a bioreactor convert the leftover urea into ammonia, which feeds into an electrochemical cell that uses the ammonia to generate electricity.”
