Problem.

Current Small Hydro Power Systems do the same with smaller technology.

Problem.

Many Micro Hydro Power Systems do the same with even smaller technology.

- high water flow rate necessary (m/sec) - high hight difference necessary (m)- high turbine rotation (rpm)- water quality depletion (cod/bod/pH)- high water accidity = high corrosion- natural water stream is cut - negative impact on animal population - upstream and downstream effects- often clogged or damaged by debris
