We are under obligation to coexist with natural ecosystem, for the next leap in the hydroelectric power devolopment. In such circumstances, this paper proposes a new type hydraulic turbine, named "Gryo-Type Hydraulic Turbine", accompanying with the principle of the rotor works and the model test results. The rotor is composed of some blades with high aspect ratio and is submerged nearly parallel to the stream. The turbine is suitable for shallow streams with high velocity in mountain torrents and/or rivers. The rotor has the self-motive power and is driven by the drag force of the blade facing to the downstream at the low rotational speed. With the increase of the rotational speed, the rotational torque comes to be caused successfully by the lift forces of the blade not only facing to the upstream but also facing to the downstream. The maximum output is at higher rotational speed, which is desirable as the turbine performance for the mini/micro hydroelectric power generation.
