The thermal banking technology that Steven Schwen uses in his innovative greenhouse (see Sustainable Energy: Thermal Banking Greenhouse Design) applies not only to conservation of heat, but to cold storage and refrigeration. In this short companion video, Schwen discusses his plans for an ice house at his farm in Minnesota, and how this project is a logical extension of his energy conservation strategy. When completed, the ice house will provide cold storage and a comfortable place for packing his produce during warm summer months.
