A newly developed innovative wind / water turbine mechanism that is driven by longitudinal vortex is introduced. The blades of a conventional propeller type windmill with a horizontal rotation axis are replaced to the simple circular cylinders and a ring shaped plate is placed in the wake region. Once the propeller starts to rotate a certain direction, the longitudinal vortex appears stably behind the cylinder and the steady lift force is generated. It can rotate to the CW or CCW direction and the rotation direction is decided by the initial rotation direction. This new turbine is the simple structure, toughness and high torque feature. Therefore, it has a great possibility to use as a wind turbine to generate electricity even in the high speed wind without the pitch controller. It can apply for wider purposes, such as a turbine with high corrosion resistance and temperature resistance. We can also manufacture a micro-size turbine easier.
