Abstract:
1. A system for cooling permafrost, comprising: a chemical reactor coupled to a source of gas located at a first permafrost region to conduct a non-combustion reaction that dissociates the gas into first and second constituents; a first conduit portion coupled to the chemical reactor to convey the first constituent in a gas phase to an intermediate location, the intermediate location having a higher elevation than an elevation of the chemical reactor; a phase change device located at the intermediate location to change the phase of the first constituent from the gas phase to a liquid phase; a second conduit coupled to the phase change device to convey the first constituent in the liquid phase to a second permafrost region; and a heat exchanger coupled to the second conduit to receive the first constituent in the liquid phase, the heat exchanger being positioned to transfer heat from the second permafrost region to the first constituent, the heat exchanger having a lower elevation than the elevation of the intermediate location.
