Natural Refrigeration: Collecting Ice in China


As Warren noted eariler, Ice harvesting is still a good way to beat the cost of refrigeration. In China, "Citizens collect ice blocks cut from the ice on the Songhua River in Mudanjiang, northeast China's Heilongjiang Province January 10, 2007. People store ice cubes at their cellars in winter for summer use." Buried in sawdust, ice can last all summer at zero cost and energy consumed (other than that cutting and moving the ice in the first place) ::China Daily via ::Splurch
