Water wheel

A water wheel (also waterwheel, Norse mill, Persian wheel or noria) is a hydropower system; a system for extracting power from a flow of water. It was a widely used system in the Middle Ages, powering most industry in Europe, along with the windmill. The most common use of the water wheel was to mill flour, where it was known as the watermill, but other uses included foundry work and machining, and pounding linen for use in paper. The largest waterwheels in the world are located in the Syrian city of Hama.
