Spacecrafts Could Use Urine As Fuel Source
New research says the urea from urine could be recycled for fuel. Urea is filtered out of wastewater when making drinking water.By Amy Kluber | April 15, 2014
Getting water and fuel to spacecrafts in orbit can get pretty expensive, but a new process could scale that down — simply by recycling urine.
Yes, urine. The idea of drinking water that was once pee sounds pretty gross, but the science behind it could provide a more affordable way to not only hydrate astronauts but also fuel spaceships. (Via CBS)
As a writer for Science puts it: "In Space, Pee is for Power." Astronauts aboard the International Space Station already recycle wastewater to recover about 75 percent of water through distillation, but the process removes the nitrogen-rich compound urea.
