Abstract:

Assembly of the first prototype 300 watt generator was completed and testing begun. Upon initial start-up two or more short circuits developed between the main section of the thermopile and the case. Information on thermopile performance was obtained from the 27 couple fan circuit which was isolated from the main thermopile and the case. Power output from the fan circuit was 34.2 watts at average junction temperatures of 1100F and 300F. This implies a gross power output from the entire thermopile 270 couples of 342 watts. Average fin base temperature on the heat sink was 250F, as predicted. Fuel consumption was approximately 1.45 lbshr which is somewhat greater than anticipated but it is felt that this can be reduced by modifications to the burner. Author
