Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for stimulating convective thermal recharge in a hot sedimentary aquifer (HSA) used in geothermal energy generation applications. An example system pumps, via an extraction well, heated water from an extraction depth of a hot sedimentary aquifer (HSA) identified based on a convective heat transfer coefficient of the HSA satisfying a threshold convective heat transfer coefficient. The system then extracts, via a power generation unit, heat from the heated water to generate power and transform the heated water into cooled water. Subsequently, the system injects, via an injection well, the cooled water at an injection depth of the HSA. As a result of these operations, the system stimulates a convective flow field within the HSA having a convective heat transfer rate sufficient to provide a convective thermal recharge of the extracted heat.

Aspects of the present disclosure relate to an extendable conductor assembly. A conductor of the extendable conductor assembly may be extended (e.g., into a thermal target, such as a preexisting or a newly created feature of a planetary body) and used to thermally couple a rover, vehicle, fixed installation, or other hardware with the thermal target. Thus, the temperature of the hardware may be managed via heat transfer to/from the thermal target. For instance, heat may be transferred from the thermal target to maintain the temperature of the hardware under cold conditions, while excess heat may be transferred to the thermal target under hot conditions. As an example, a rover may form a borehole in the lunar surface, in which a conductor may be extended to facilitate heat transfer between the rover and the Moon accordingly.
