Geothermal Ice Wall

Check this out……the take away is using a geothermal system for heating an indoor space (no fossil fuels) and then using the waste from that process (super-cold water) to form controlled walls of ice. One of the advantages of super-cold water is that it forms ice faster, so more control over shaping the surface.
