STUDY OF PHOTOSYNTHETIC GAS EXCHANGER AS A METHOD OF PROVIDING FOR THE RESPIRATORY REQUIREMENTS OF THE HUMAN IN A SEALED CABIN

摘要

The most significant result of work with the model photosynthetic gas exchanger is almost. Obscured in the technicalities of the. Preceding presentation. Efficiencies of about 17 to 18 percent may be maintained during steady oper¬ation over periods of 5 to 10 days. Longer' operation was not attempted. The only techni¬cal difficulty of indefinite operation lies in the tendency of Chlorella to stick to the glass walls of the chamber. By application of a silicone coating to the glass this difficulty is minimized over a 2-week period but could not be effective indefinitely. Such a mechanical characteristic is an important factor in selection of an alga for practical use.
