✦ Synopsis

Abstract

A system is described which uses photosynthesis to regenerate oxygen from exhaled carbon dioxide in sealed cabins in the absence of gravity. Design considerations as to choice of algal strain, illumination, nutrients and gas‐exchange methods are discussed. Details are given of such an apparatus, of laboratory size, used to evaluate selected semipermeable gas‐exchange membranes. Data is presented and extrapolated to estimate size and weight of a possible manned space system.
