SAGE Solar Panel Tests, 1974 [photograph].

SAGE Hot Water Solar Panel, 3 Apr 1974. [Photo index]. The Solar-Assisted Gas Energy (SAGE) project was sponsored by the Southern California Gas Company beginning in 1973. Its purpose was to investigate the commercial possibilities of solar-assisted gas energy for heating water. A solar collector array was constructed on the roof of building 82 in April 1974. It was connected to a storage tank, heat exchanger, gas boiler, electric heater, pumps, valves, and instrumentation. This system, suitable for a ten unit apartment building, was used to test and evaluate various water heating system designs. This photo shows the array being assembled on the south-facing roof slope, with buildings 83 and 238 in the background. In the next phase of the project, similar systems were installed in apartment buildings in El Toro and Pasadena. You can learn more about the project by visiting the JPL Archives "Going Green" exhibit, on display in the Library (building 111). The equipment was removed from building 82 and the SAGE Project never made it past the pilot phase. Solar heating was not found to be economical enough for commercial success.

One of the first people hired at GALCIT Project #1 in November 1941 was photographer George Emmerson (1913-1994), an emigrant from Newcastle, Great Britain. Audrey Voice and Mary J. Taylor as photographer's assistants joined Emmerson in 1943. Emmerson took almost all the early photos that became a part of this collection, a collection described in brief as the work product of the JPL Photolab. As JPL grew, so did the assignments to the Photolab to photograph all Laborato...
