The initial investment needed for such installations is typically high. To make it worthwhile and obtain a high power yield, a large number of turbines would be required. However, as fish are known to collide with the turbines placed in their stream, the authorities have imposed guidelines that allow no more than 0.1% fish mortality per passageway. The system has been tested, and has been proven to meet these specifications
The turbine is designed to be self starting, due to a confidential system to control the blade orientation which has been developed by Physixfactor. The turbine can be used in rivers while fish can still pass the turbine system.
Test opstelling waarin het vermogen wordt getest bij verschillende stroomsnelheden. In deze opstelling zijn ook vissen aanwezig, en testen hebben aangetoond dat meer dan 99.5% van deze vissen de opstelling probleemloos kunnen passeren.
