Underground homes and earth-sheltered homes are among the most popular types of alternative homes. Almost everyone knows the earth will moderate the inside temperature and reduce energy costs. That’s why potato storage cellars are common. These structures will “assure the grower that potatoes will be held at the proper temperature from harvest time to shipping time, anywhere from March to May.” Of course, the same principle can be used to build energy efficient homes, storm shelters and rootcellars.
According to the image description, the photo above is a “Quonset hut potato storage cellar in southeastern Idaho. Cellars built for the storage of large amounts of potatoes came into use in the early 1900s. Loose or baled straw was laid on top of pole rafters, and the roofing material on top of that. Roofing material could be wood shingles or tin. Dirt was piled up on the sides and even on top as in the case of a sod roof. There are several different roof types in cellars that have developed since 1900. Today, the Quonset hut dominates the industry.”
