In 1930, Albert Einstein and another physicist patented a refrigerator with no moving parts; why did their invention never reach your kitchen?

In a remarkable collaboration, Albert Einstein and Leo Szilard advanced the world of refrigeration with a groundbreaking patent. Their design ingeniously harnessed chemical reactions to achieve cooling without relying on electricity. By cycling ammonia, butane, and water, they promoted a cleaner approach to refrigeration. Although it didn't see commercial success, this innovative concept paved the way for future prototypes and alternatives in the cooling industry.
