Abstract: A generator device includes a fluid confluent guide device including guiding plates and a housing having an inlet, a curved member, and a transverse channel as an outlet; and a wheel including two spaced rims having teeth, and blades between the rims. The electric turbine generator converts the energy of flowing water (e.g., sea water) or wind into useful forms of power. Fluid entering a space between the two adjacent guiding plates is divided into rotating fluid portions. The fluid strikes the blades in an optimum angle. The wheel without axle works well with decreased fluid velocity. The electricity generating devices are driven by the wheel. Total electricity generation is borne by the electricity generating devices. A single electricity generating device has a relatively small weight. This can lower the risk of installation. Locations having a lower fluid velocity can be selected for installing the electric turbine generator.
