A turbine having a rotor assembly with substantially cylindrical blades. A scoop may be used to direct a fluid flow into the turbine, thereby causing a pushing force and/or a suction force to be exerted on at least some of the cylindrical blades. Accordingly, the rotor assembly may rotate within the turbine. In an example, the rotor assembly may include a plurality of magnets, which may cause a magnetic field to fluctuate. Copper discs on the turbine enclosure may be used to generate electricity based on the changing magnetic field. In another example, the turbine enclosure may have one or more openings, which may generate a suction or pressure force as the rotor assembly rotates.

The application relates to unidirectional hydrokinetic turbines having an improved flow acceleration system that uses asymmetrical hydrofoil shapes on some or all of the key components of the turbine. These components that may be hydrofoil shaped include, e.g., the rotor blades (34), the center hub (36), the rotor blade shroud (38), the accelerator shroud (20), annular diffuser(s) (40), the wildlife and debris excluder (10, 18) and the tail rudder (60). The fabrication method designs various components to cooperate in optimizing the extraction of energy, while other components reduce or eliminate turbulence that could negatively affect other component(s).
