Description330-PSA-33-60 (USN 710696) (20904612181).jpg | 330-PSA-33-60 (USN 710696): New Navy Thermoelectric Generator Under Test. One of the two 2500-watt “sub-generators” which make up the largest known thermoelectric power plant ever constructed is shown under test at the Westinghouse New Products Laboratories. Developed for the Bureau of Ships, U.S. Navy, the generator is intended as an experimental unit for materials evaluation and generates enough electric power to carry the full lighting load of 8 to 10 average homes. The generator is fired by kerosene and operates at a temperature of 1200 degrees Fahrenheit. Using a modular type of construction, the unit can supply a wide variety of output voltages and currents. Engineer William Moreland takes a temperature reading on the new generator. Photograph released May 16, 1960. (8/25/2015). |
