Abstract:
1. A hydrokinetic water turbine system configured to be placed in a flowing stream of water, said water turbine system comprising, in combination: a frame structure; a rotor shaft supported by the frame structure to rotate about a horizontally-disposed central axis of the rotor shaft; a rotor secured to the rotor shaft and having a first plurality of spaced-apart blades parallel to the central axis of the rotor shaft and circumferentially spaced apart about the rotor shaft, and a second plurality of space-apart blades extending parallel to the central axis of the rotor shaft and circumferentially space-apart about the rotor shaft so that the flowing stream of water revolves the rotor about the central axis of the rotor shaft; wherein the first and second plurality of blades are each rigidly secured to prevent relative movement between each of the blades; wherein the first and second plurality of blades are each straight in the longitudinal direction and have a hydrofoil shape in cross-section configured to generate lift and rotate the rotor about the horizontally disposed central axis as the flowing stream of water passes around the hydrofoil shape; wherein the second plurality of blades is spaced-apart from the first plurality of blades in the longitudinal direction and offset from the first plurality of blades so that the second plurality of blades is circumferentially located between the first plurality of blades for smooth rotation of the rotor; and a water pump having an inlet configured to intake water from the flowing stream of water, an outlet configured to outflow water from the stream of water, and a pump shaft directly driven by rotation of the rotor and configured to rotate at the same speed of rotation as the rotor.
