This method is somewhat similar to a machine gun, in terms of using re-coil method to generate force ( power).
A cylindrical heavy object is placed on the circular track which has pressure points . This heavy mass will be tilted to an angel where it becomes very easy to rotate it with very less force .ALL the force of the mass will be at one place.( This can be understood with a diagram) .Then we have to rotate this object along the track which has re-coil pressure points. As this object moves over the pressure point's, then the instrument is "LOADED"( like a gun) and as this moves along the object keeps "loading" many pressure points. These loaded " springs" or " air pressure points can be triggered and the energy stored can be diverted to make the turbine rotate.
By this method we can get more power with little effort.
