| has gloss | eng: A water scoop is a simple hydropower machine–that is, a machine used to extract power from the flow of water. Unlike a water wheel it operates intermittently, like a seesaw: A container (a bucket or cup) at the end of a lever is filled with water in the upper position. The container side becomes heavier, and so the lever with the filled container moves downward, which may be used to operate a machine drive. In the lower position the container is emptied, and the lever moves back into the upward position. |
