A highly instrumented photosynthetic gas exchange system was designed, fabricated and tested for handling the carbon dioxide output and supplying the oxygen requirements of one man. The system designed consists of three major components: (1) a multi-pass light chamber containing thirtysix 96-inch 'Power Groove' fluorescent lamps, (2) a counter-current gas contacting tower, and (3) an instrumentation console for controlling and recording the important parameters. In addition, a centrifuge is provided for the harvesting of algae. Based on the growth rate of the algae, this study demonstrated that this system has the capability of supporting one man.
