The present paper discusses the nature and requirements of a sustenance system. Its components include a stabilization process for urine and feces, a reclamation process for recovery of potable water from body wastes, and a photosynthetic gas exchange process for production of oxygen and food from algae culture. The system described offers interesting research opportunities for sustaining man in a closed environment.
