Gravitation water vortex power plant

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).

[2] The specific design described here was first patented by Greek-Australian Lawyer and Inventor Paul Kouris in 1996,[3] who was searching for a way to harness the power inherent in a vortex.

[dubious – discuss] Later, Austrian Inventor Franz Zotlöterer created a similar turbine while attempting to find a way to aerate water without an external power source.

The water forms a vortex over the center bottom drain of the basin.

[4] The turbine's aeration of the water is used to improve water conditions, while the reduced speeds of the turbine and the lack of cavitation are designed so that most types of fish can pass through the turbine freely, something which is much more difficult to achieve at normal hydro plants that require additional structures for the fish migration.
