| 説明 | Original Caption: Blackened aluminum collector cups are the heart of the solar energy collector developed by the International Solarthermics Corporation. The firm claims such cups provide a larger collector surface from a smaller area than the conventional black surface which is flat. The sups allow for a reduction in total area and size for the collector unit. A blower circulates air behind the class and over the cups, forcing heated air into rock storage inside the a-frame housing, 05/1975.U.S. National Archives’ Local Identifier: 412-DA-14862Photographer: Norton, BoydSubjects:Environmental protectionNatural resourcesPollutionNederland (Boulder county, Colorado) inhabited placePersistent URL: research.archives.gov/description/557314Repository: Still Picture Records Section, Special Media Archives Services Division (NWCS-S), National Archives at College Park, 8601 Adelphi Road, College Park, MD, 20740-6001.
