Mechanical fans were born in 1830. An American named James Byron was inspired by the structure of clocks and invented a mechanical fan that could be attached to the ceiling and driven by a spring. The cool, slow breeze brought by the rotating blades of this fan makes people feel cool, but it is difficult to climb a ladder to climb back up.
