  • The design of a vortex water turbine for the utilization of renewable energy potential, this technology can be called clean energy because it is environmentally friendly, but its utilization is still small scale and uses simple technology.A vortex turbine is a turbine that utilizes a whirlpool as an intermediary medium for energy on the vertical axis so that there is a pressure difference between the axis and its surroundings. This type is very suitable for river flows with a low headThe turbine is designed to operate at a discharge of 0.5 l/s with a head of 1 m, The design and calculation results are as follows: consists of 3 blades with runner dimensions 0.5 m, 50 mm shaft using S 45 C material, bearing Ø outside 80 mm, Ø inside 50 mm, vortex pool Ø 1m and produces 4.9 kw of power
