Leonardo da Vinci designed a sort of prototype of a refrigerator

Wow.

The machine creates a blast of cold air to cool down the contents of a central pitcher, apparently.

A sketch by Leonardo da Vinci of a “cooling machine” has been brought to life, with a working model of the contraption being presented in Milan.

The inventor’s design, which has been dated to around 1492, included both a drawing of the machine and a theoretical explanation of how it would work, the Firenze Today website reports. It was likely designed for drinks, or perhaps sorbets and desserts, the report says. The machine uses a large, circular bellows to create a blast of cool air, which is then channelled through multiple nozzles to concentrate it on a central pitcher.
