The gravitational vortex water turbine puts a spin on small hydro
The interest in small hydropower systems, which can be used to generate local and off-grid electricity in small rivers and streams, has led to the development of a number of new designs all exploiting technologies which are not suitable for large scale hydro generation.
The vortex turbine uses both kinetic (run of river) and static potential energy (head) principles and promises to provide a power generation system that results in minimum interference with the river and aquatic life.
Mini hydropower plants have a good potential for providing electricity to remote communities. The gravitational water vortex power plant (GWVPP) is an economic and clean energy system which allows the conversion of the low-head potential energy into kinetic energy to drive power turbines by using a gravitation vortex pool.
