Mechanical ventilating fan, Reinvented by Leonardo da Vinci

Mechanical ventilating fan was invented in China circa 180 CE. It was a rotary ceiling fan meant to draw cool air upward into the room. Power was provided by servants turning a crank. A water-powered ventilating fan was invented by Leonardo da Vinci in 1500, and a similar device was used in England in 1533 to provide ventilation for a mine.
