waterwheel
Current-powered rotating device
A waterwheel is a large wheel fitted with paddles or buckets around its rim, positioned so that flowing or falling water turns it.
The rotation powers machinery—historically for grinding grain, sawing lumber, or driving bellows.
Waterwheels were the primary source of mechanical power before steam engines: The old mill's waterwheel still turns, though it no longer grinds flour.
