Gravitation water vortex power plant
A gravitation water vortex power plant is a micro hydro power plant which is capable of producing energy using low heads 0.7 to 3 metres. The technology is based on a round basin with a central drain. Above the drain the water forms a stable line vortex which drives a water turbine.
As an added advantage, the inventor refers to the fact that the turbine aerates the water, helping improve water conditions, while the reduced speeds of the turbine, and the lack of cavitation ensure that most types of fish can pass through the turbine without danger, something which is much more difficult to achieve at normal hydro plants that require additional structures for the fish migration.[1][2]
Because of the intensive aeration of water by the gravitation water vortex - in the rotation tank of the gravitation water vortex power plant is an ideal living area for aquatic plants, microbes and fish.
How it works

The water passes through a straight inlet and then passes tangentially into a round basin. The water forms a big vortex over the center bottom drain of the basin. A turbine is withdrawing rotational energy from the vortex, which is converted into electric energy by a generator. [3]
