Solar Oven

Description
Charles Greeley Abbot (1872–1973), the second director of the Smithsonian Astrophysical Observatory and the fifth secretary of the Smithsonian Institution, spent his scientific career measuring the intensity of solar radiation and seeking to correlate solar changes with weather conditions on the earth. He was also interested in the practical use of solar radiation. This cooker, which he built in 1940, uses a cylindrical aluminum mirror that is mounted parallel to the earth's axis to collect solar energy and focus it on a pyrex tube that is filled with a chlorinated benzene ("arochlor"); the energy is then transmitted to a square oven in which cakes and cookies could be baked. Abbot obtained a patent (#2,247,830) on this cooker in 1941.
