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.
