1930The Einstein refrigeratorA patent with Leo Szilard, and no moving partsAfter reading about a family killed by leaking refrigerant, Einstein and Szilard designed an absorption refrigerator driven by heat with no mechanical pump. The US patent was granted in 1930. Freon arrived soon after and the design was shelved, though the pump principle was later used in breeder reactors.
