Einstein–Szilard refrigerator

After hearing about a refrigerator that leaked toxic fumes and caused the deaths of some people in Germany, Einstein decided to invent a new, safer refrigerator.

He teamed up with his student, Leo Szilard, to invent a refrigerator with no moving parts that works at a constant pressure, all of which somehow eliminates the risk of escaping toxic fumes. The two came up with 45 different patents for the design.

The cool thing is, this fridge runs on heat to keep things cold through the magic of science, meaning someone could invent a solar-powered fridge using these plans.
