Query: The applications of subsurface assemblies on thermoelectric generators
  for lunar processes   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.
