• the habitat of the fish is not affected because the system rotates according to the flow of water and no shearing action is generated by this. The fish can swim through the plant or even past the plant.
• the energy generated by the flow energy S is converted into other forms of energy, as needed, using suitable transmissions (e.g., gear transmissions, toothed belt transmissions), clutches, e.g. to compensate for relative movements between a drive shaft (here shaft of the rotor) and an output shaft (e.g., shaft of a generator) and corresponding transducers converted.
