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 ).
Einstein and Szilard themselves named it the "Einstein Refrigerator" in the document shown in the article, notice the name in big letters and the signatures of both inventors. 77.215.46.17 20:59, 2 June 2010 (UTC) Here is support for moving this article to Einstein-Szilard refrigerator. Dannen, Geene (1997).
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
The Einstein refrigerator is invented by Albert Einstein and Leo Szilard. Ulster-born engineer Harry Ferguson is granted a British patent for his 'Duplex' hitch linking tractor and plough. German engineer Andreas Stihl patents and develops an electric chainsaw. [21]
A refrigerator which is compressorless (no compressor) and maybe also fanless (no fan). Is there such a thing at least under research if not in retail markets? Please refer me to an article or share some data. Thanks a lot. 2A10:8012:17:CDC6:9584:54AE:7AE6:F8E7 07:11, 16 May 2023 (UTC) Have a look at Einstein refrigerator.

Designed for the Einstein–Szilard electromagnetic refrigerator (not the pumpless Einstein refrigerator), it uses electromagnetic induction to move conductive liquid metal without electrodes, to compress a working gas, pentane. [1] It is a liquid linear induction motor.
