Water wall turbines do not require barrages or catchment ponds and thus have minimal impact on the tidal effect in estuaries, making them suitable for sensitive environments. All of the electrical and mechanical components of a water wall turbine are in closed-containment above the waterline, mitigating the environmental impact to the waterway.
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 gravitation water vortex power plant is a type of micro hydro vortex turbine system which converts energy in a moving fluid to rotational energy using a low hydraulic head of 0.7–3 metres (2 ft 4 in – 9 ft 10 in). This technology is based on a round basin with a central drain. Above the drain, the water forms a stable line vortex which ...
Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [ 1 ]
Water pressure motors, having a piston and cylinder with inlet and outlet valves: their action is that analogous of a steam- or gas-engine with water as the working fluid – see water engine; Water wheels [2] Turbines, deriving their energy from high velocity jet of jets (the impulse machine), or from water supplied under pressure and passing ...
The Steffturbine is driven by the potential energy of the water, it operates like an overshot water wheel. It comprises a conveyor chain equipped with profiled paddles circulating around two wheels. These wheels are arranged so that the flowing water drives the conveyor chain on an inclined plane. [2] Different turbine inclinations are possible.

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]
