The runner of the small water turbine. A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation.
The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [ 1 ] [ 2 ] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel .
A cross-flow turbine, Bánki-Michell turbine, or Ossberger turbine [1] is a water turbine developed by the Australian Anthony Michell, the Hungarian Donát Bánki and the German Fritz Ossberger. Michell obtained patents for his turbine design in 1903, and the manufacturing company Weymouth made it for many years.
Water wheel: Water wheels can be used at low heads (1–5 metres) and medium flows (0.3–1.5 m 3 /s) and are considered safe for aquatic life. Gravitation water vortex power plant: This type of hydro power plant use the power of a gravitation water vortex, which only exists at low head.
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. [1] The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. [1]

Between 2004 and 2010, [1] Lodewyk Botha and Marek Sredzki developed an inflow turbine that captures water's potential energy in addition to its kinetic energy. Principal patents [2] [3] for the technology were registered and published between 2005 and 2011. The first full-scale water wall turbine project was completed in 2016 by Water Wall ...
