in the 1870s Lester Allan Pelton invented The Pelton wheel a water turbine that extracts energy from moving water. Many variations of water turbines existed prior to Pelton’s design, but they were less efficient.Pelton_patent

Because water can’t be compressed, most all of the energy is extracted in the hydraulic turbine. Therefore, Pelton wheels have only one turbine stage, unlike gas turbines that operate with steam. The largest units can be up to 200 megawatts. The smallest Pelton wheels are only a few inches across, and can be used to tap power from mountain streams having flows of a few gallons per minute. Some of these systems use household plumbing fixtures for water delivery. These small units are recommended for use with thirty meters or more of head, in order to generate significant power levels. I have added this video of a self running device that is not using a very efficient water turbine.
