Like Wet Hay. McClure's bubble-breathing experience was part of an experiment by the Boeing Airplane Co. in Seattle, which is seeking an oxygen sys| tem that will support human space travelers. Using live algae to recycle the precious oxygen in spaceships is a venerable idea, but it is far easier to accomplish in fiction than in fact. Many space-minded companies have added algologists to their staffs, but Boeing believes it is the first to keep a man alive for a full day on algal oxygen. The original air in McClure's tank would have become...
Using energy taken from the light, the algae absorbed the carbon dioxide given off by McClure's lungs and replaced it with oxygen. The air in the closed system smelled like wet hay, but it stayed rich in oxygen (21%), while its CO2 content never got higher than a harmless...
...Life Support Systems Research, is proud of his group's success, yet he has no illusions that algae will join the crews of spaceships for quite some time. In principle, algae are ideal, requiring nothing but the sunlight filtered through a spaceship's windows to regen erate oxygen and dispose of CO2. But they demand a lot of water to live happily; the Boeing system contains 80 gal lons, weighing more than 600 Ibs. Pilgrim is sure that this prohibitive weight can be reduced drastically, but he has other problems besides. Algae are delicate; they sometimes sicken, turn...
With $40,000 plus Cassavetes' sensitive and indirect direction, the actors improvised a sincere, original, powerful film. Always crude, often trite, sometimes even phony, this rackety little race opera is nevertheless loaded, like a truck full of oxygen cylinders, with huge, impounded energies...
Cookies, Too. Pilgrim believes that on short space jaunts the crewmen will breathe bottled oxygen. For longer voyages, a chemical recycling system that Boeing has developed looks more practical. It uses potassium or sodium super-oxide to generate oxygen and absorb CO2. Only on very long voyages, the sort that are measured in years, will closed systems using algae be the most efficient. On such space ventures, the crew may even be able to eat the excess algae (Pilgrim's daughter Vicki Leigh, 15, has made acceptable cookies of them), eliminating much of the need for toting food...
