treadwheel
Noun: A treadwheel is a type of large, vertical wheel or cylinder, often made of wood, that is powered by the continuous walking or climbing motion of a person or animal inside it. This motion turns the wheel, which is connected to machinery to perform work, such as grinding grain, lifting water, or powering a crane. Historically, it was a common source of power before the widespread use of engines.
