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 ).
Szilard coined and submitted the earliest known patent applications and the first publications for the concept of the electron microscope (1928), the cyclotron (1929), and also contributed to the development of the linear accelerator (1928) in Germany. Between 1926 and 1930, he worked with Einstein on the development of the Einstein refrigerator.
1926 – General Electric Company introduced the first hermetic compressor refrigerator; 1929 – David Forbes Keith of Toronto, Ontario, Canada received a patent for the Icy Ball which helped hundreds of thousands of families through the Dirty Thirties. 1933 – William Giauque and others – Adiabatic demagnetization refrigeration
1930 – Patent number US1781541 is awarded to Albert Einstein and Leó Szilárd for their invention, the Einstein refrigerator; 1973 – Death of Artturi Ilmari Virtanen, Finnish chemist, Nobel Prize laureate (b. 1895)
In 1926, Einstein and his former student Leó Szilárd co-invented (and in 1930, patented) the Einstein refrigerator. This absorption refrigerator was then revolutionary for having no moving parts and using only heat as an input. [303] On 11 November 1930, U.S. patent 1,781,541 was awarded
1930 - Patent granted for Einstein-Szilard refrigerator designed by Albert Einstein and Leó Szilárd. APS. 1919 - Elmer Imes's published work presented the first accurate measurement of the distance between atoms in molecules with high resolution infrared spectroscopy. APS.
