The applications of subsurface assemblies on thermoelectric generators for lunar processes

Abstract

To take advantage of the distinctive nature of the lunar environment with respect to heat flow due to the low thermal conductivity of lunar soil and the moon's negligible atmosphere, thermoelectric generators have been identified as a potential power source to support self-sustaining processes on the lunar surface. These power-generating systems will take the form of top-down heat transfer systems, relying on soil as the heat sink to maintain significant temperature differentials. Installation of increasingly complex subsurface assemblies to redirect subsurface heat flow have demonstrated strong capability in both enhancing power output and limiting near-surface temperatures.
