2. Turgo turbine - Wikipedia

   en.wikipedia.org/wiki/Turgo_turbine

   The water's potential energy is converted to kinetic energy with a nozzle. The high speed water jet is then directed on the turbine blades which deflect and reverse the flow. The resulting impulse spins the turbine runner, imparting energy to the turbine shaft. Water exits with very little energy. Turgo runners are extremely efficient

3. Screw turbine - Wikipedia

   en.wikipedia.org/wiki/Screw_turbine

   A screw turbine at a small hydro power plant in Goryn, Poland. The Archimedean screw is an ancient invention, attributed to Archimedes of Syracuse (287–212 BC.), and commonly used to raise water from a watercourse for irrigation purposes. In 1819 the French engineer Claude Louis Marie Henri Navier (1785–1836) suggested using the Archimedean ...

4. Water power engine - Wikipedia

   en.wikipedia.org/wiki/Water_power_engine

   The water powered turbines used in these dams need little maintenance, are easily upgradable with modern technology, and have a lifespan of 50–100 years. Clean energy created by hydro power plants attracts positive results in otherwise remote areas. It enhances commerce and gives rise to more industry.

5. Pelton wheel - Wikipedia

   en.wikipedia.org/wiki/Pelton_wheel

   Old Pelton wheel from Walchensee Hydroelectric Power Station, Germany. 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 ...

6. Water turbine - Wikipedia

   en.wikipedia.org/wiki/Water_turbine

   The main difference between early water turbines and water wheels is a swirl component of the water which passes energy to a spinning rotor. This additional component of motion allowed the turbine to be smaller than a water wheel of the same power. They could process more water by spinning faster and could harness much greater heads.

7. Water wall turbine - Wikipedia

   en.wikipedia.org/wiki/Water_Wall_Turbine

   The turbine's bidirectional rotation operates inline with the free current flow. Both potential and kinetic energy are harvested, providing higher energy extraction efficiency than a kinetic energy only approach. This is the principal difference between traditional water wheels and the water wall turbine design.

8. Hydropower - Wikipedia

   en.wikipedia.org/wiki/Hydropower

   Some hydropower systems such as water wheels can draw power from the flow of a body of water without necessarily changing its height. In this case, the available power is the kinetic energy of the flowing water. Over-shot water wheels can efficiently capture both types of energy. [7] The flow in a stream can vary widely from season to season.

9. Water wheel - Wikipedia

   en.wikipedia.org/wiki/Water_wheel

   A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wheel (usually constructed from wood or metal), with numerous blades or buckets attached to the outer rim forming the drive mechanism. Water wheels were still in commercial ...
