 Einstein refrigerator

The Einstein refrigerator, also known as the Einstein engine or the Einstein refrigerator cycle, is a type of absorption refrigerator that was co-invented by Albert Einstein and his colleague Leo Szilard in the early 1920s. The invention aimed to create a more efficient refrigeration system that operated without moving parts and would use safe and non-toxic refrigerants. The design of the Einstein refrigerator relies on the principles of thermodynamics and uses a combination of temperature differences and absorption techniques to provide cooling.
