Whatever happened to the refrigerator Einstein helped invent?
While it never became a commercial success, its underlying concepts became the basis for cooling nuclear breeder reactors.
Einstein and Szilard‘s idea avoids the need for freons. It uses ammonia, butane and water and takes advantage of the fact that liquids boil at lower temperatures when the air pressure around them is lower.
