dieseltaylor Posted September 2, 2009 Share Posted September 2, 2009 About geo-thermal power for houses : ) Something to alter the power/cost equation. Invented by GeoEnergy Enterprises, a start-up energy technology firm with a decade of ground-source experience, the GeoColumn is a self-contained ground-source heat pump that does not require ground water, water pumping, or anti-freeze agents to function. Unlike other ground source systems, it can be installed in a relatively small space for light commercial projects. The GeoColumn comes housed in a sealed vessel. Inside this container, a gas heat-exchange medium circulates through coils of copper tubing submerged in ordinary, unconditioned water. The entire system is buried in a borehole 23 ft deep, which can be dug easily by light, truck-mounted drilling equipment. http://www.csemag.com/article/328151-Hybrid_HVAC_system_uses_improved_ground_source_heat_pumps.php?nid=2459&rid=7231091 For the actual company site: http://www.geoenergyusa.com/ 0 Quote Link to comment Share on other sites More sharing options...
