The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd , who patented it in the U.S. on November 11, 1930 ( U.S. patent 1,781,541 ).
An image from the Fermi–Szilard "neutronic reactor" patent. Szilard received German citizenship in 1930, but was already uneasy about the political situation in Europe. [29] When Adolf Hitler became chancellor of Germany on January 30, 1933, Szilard urged his family and friends to flee Europe while they still could. [20]
