The Rolling turbine, also known as the rolling fluid turbine, bladeless turbine, precession turbine, or SETUR turbine, is a novel type of water turbine.

The Rolling turbine is based on a novel fluid dynamics that was not theoretically understood at the time of the discovery. A circular rotor is freely suspended in a circular cavity of a confusor. As water flows through a gap, the rotor rolls around the surface of the cavity of the stator, making a characteristic precession motion.

Development & Awards
Miroslav Sedlacek was inspired by the motion of a The turbine was first patented by Miroslav Sedláček in 19XX.

Theory of Operation
In principle, the fluid dynamics principle applies to a wind power and Miroslav Sedlacek developed a rolling wind turbine prototype.
