Abstract: A Styrofoam-filled plastic cylinder that has collapsible paddle wheel fins attached about the circumference. Two shafts extend from the ends of the cylinder. The shafts are held by bearings. The bearings are attached to a frame structure that is embedded into the seabed. The shafts then extend past the bearings and are connected to a gear drive system that, in turn, connected to generators or other mechanical devices.

Platforms on either side of the cylinder rise and fall with tidal action to maintain effective contact with the water at all times. Moreover, because the structure is positioned at or near the water surface, maintenance is much simpler for this device.

Abstract: The present invention concerns a wind turbine having a plurality of vertically extending airfoils forming a rotating carousel rotating about a central axis thereof. The airfoils pivot about their leading edges to adjust the pitch angle thereof to maximize energy harvest when the airfoils are rotating both in an upwind direction and in a down wind direction. This pivoting movement results from trailing edges of the airfoils being pivotally secured to rigid spokes or cables of a trailing edge hub. An adjustment mechanism is pivotally mounted between a carousel hub and the trailing edge hub and is used to control the separation between a central axis of the trailing edge hub and the axis of rotation of the carousel as they co-rotate. As the carousel rotates, the offset distance between the two axes determines the maximum achievable pitch angle of each airfoil.
