Atomic lighthouse

In 1964, the first U.S. atomic-powered lighthouse was put into operation in the Chesapeake Bay, Baltimore Harbor, Md. Designed to supply a continuous flow of electricity for ten years without refuelling, the 60-watt nuclear generator generated heat from strontium-90 in the form of strontium titinate, a safe radioisotope. The heat was converted to electricity by 120 pairs of lead telluride thermocouples. Complete with shielding, the unit was only 34.5 inches high and 22 inches in diameter. It was designed and produced by the nuclear division of Martin-Marietta Corp.
