O2 space recycle proposals

NASA’s Space Technology Mission Directorate is taking proposals to develop systems to safely and efficiently regenerate oxygen for future space voyages. Through the Game Changing Development Program, NASA is taking proposals from NASA centers, government agencies, federally-funded research groups, academic institutions, commercial companies and nonprofits. NASA already has a 40 percent oxygen recycle system onboard the International Space Station. The new technology being solicited needs to increase the oxygen recovery rate to at least 75 percent. NASA plans to dole out about six Phase I awards [up to $750K each] for teams who submit winning proposals for the design, development and testing. Under a Phase II, selected teams will build a prototype. Source: Space.com, 04/16/14.
