NASA scientists have proposed an ingenious and remarkably resourceful process to produce "clean energy" biofuels, while it cleans waste water, removes carbon dioxide from the air, retains important nutrients, and does not compete with agriculture for land or freshwater.

When astronauts go into space, they must bring everything they need to survive. Living quarters on a spaceship require careful planning and management of limited resources, which is what inspired the project called “Sustainable Energy for Spaceship Earth.” It is a process that produces "clean energy" biofuels very efficiently and very resourcefully.
