Gravitation Water Vortex Power Plant

The gravitation water vortex power plant is a type of micro-hydro vortex turbine system that converts energy in moving fluid into rotational energy using a low hydraulic head of between 0.7 and 3 metres. It operates through a round basin with a central drain, where the water forms a stable line vortex that drives a water turbine. Theoretical energy conversion efficiency can reach up to 85 percent, with one test installation demonstrating 73 percent efficiency, and the design offers environmental benefits including water aeration and fish-safe passage through the turbine, owing to its reduced rotational speed and absence of cavitation effects, advantages over conventional hydroelectric installations that require separate fish migration structures.
