While trying to find a method for aerating water without energy input, Austrian engineer Franz Zotlöterer stumbled across the idea of a mini-power plant which is simple to construct and has a turbine efficiency of 80% but which is safe for fish due to low turbine speed and improves water quality by oxygenation. Needless to say, he quickly applied for the patents. The technology can be applied with water drop as little as 0.7 meters. Zotlöterer's website suggests an idyllic installation along a modern stream that has had its meanders rudely obliterated in the interest of human civilization. His vision is to restore the health of the running water to where it was before human intervention led to reduced oxygenation due to laminar flows--while winning power at the same time.

Advantages to Gravitational Vortex Turbine Power Plant



Zotlöterer describes the many advantages of the gravitational vortex turbine power plant:
