Einstein made a refrigerator that required no electricity and had no moving parts

In the 1920s there were news reports about a Berlin family being killed when a seal in their refrigerator broke and leaked toxic fumes into their home.

This inspired the one and only Albert Einstein to design a refrigerator that didn't use any moving parts, thinking that eliminating any moving parts would also eliminate the possibility of a seal breaking.

Einstein worked with his former student Le Szilrd on the fridge from 1926-33, and based the design on a similar invention a few years earlier by a couple of Swedish investors.

The refrigeration cycle uses ammonia pressure-equalizing fluid, butane refrigerant, and water absorbing fluid, has no moving parts, and does not require electricity to operate, needing only a heat source, e.g. a small gas burner or electric heating element or even solar energy.

Although named after Einstein, it's likely that Szilrd did most of the actual inventing while Einstein consulted and did most of the patent work (he had worked in a patent office earlier in his life).
