Abstract: | In the context of investigations to maximize the operational utilization of local resources on other worlds, a concept for using fine lunar sand as cooling medium for the rejection of waste heat is developed. Sand at cryogenic temperature is admixed to the working fluid containing the waste heat. Gas and sand form a mix of the desired and temperature of the working fluid. Subsequently, the sand is removed and intensely radiation-cooled, utilizing its very large ratio. Thereafter it is recycled. It is shown that, compared to heat rejection by radiator, harenodynamic cooling offers superior efficiency, greater compactness and lower cost, improving the economics of nuclear power plants and of industrial expansion on the Moon in general. |
