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. When installed in the sea, the cylinder will turn in the swells/tidal action for as long as the ocean produces waves. 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.
