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 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]
Segner-wheel: A – water inlet, B – vertical tube with rotor, C – rotor with nozzles (side view), D – rotor with nozzles ("top" view), E – hole in the ground, F – belt-pulley transmission, G – powered device. The Segner wheel or Segner turbine is a type of water turbine invented by Johann Andreas Segner in the 18th century. [1]
The impulse energy of the water jet exerts torque on the bucket-and-wheel system, spinning the wheel; the water jet does a "u-turn" and exits at the outer sides of the bucket, decelerated to a low velocity. In the process, the water jet's momentum is transferred to the wheel and hence to a turbine. Thus, "impulse" energy does work on the turbine.

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 ...
