Keirn, United States Air Force. The device has no moving parts. It is cylindrical, approximately 5 1/2 inches high, 4 1/2 inches in diameter, and weighs five pounds. Snap III was an Air Force requirement to develop auxiliary nuclear power sources for satellite and space vehicles. Other uses may be unattended weather stations, harbor beacons and sonar buoys. The devices expected optimum capacity in about 100 watts. Snap III is powered by the isotope polonium-210. The radiation from the polonium is converted directly into electricity by means of thermo electric materials (thermocouples). Contractual and development work was initiated on this project in September 1958. The Joint AEC-Air Force Management Office awarded the contract to the Martin Company of Baltimore, who subcontracted the thermo-electric conversion device program to the Minnesota Mining and Manufacturing Company. Snap III takes its name from the program under which it was developed--the Systems for Nuclear Auxiliary Power Program of the Aircraft Reactors Group. The covered model at left is attached to a propeller which it whirls and a tiny light bulb which it illuminates. Photo measures 10 x 8.25 inches. Photo Is dated 1959.
