Abstract: A system for hydrokinetic energy conversion of a fluid current is disclosed. The system includes at least two floating platforms, each floating platform has a movable paddle that moves up to an elevated position and moves down to a low position. A transmission mechanism is included to operatively couple floating platforms to a power generator, so that, when in operation, alternatively, a first floating platform, having the movable paddle in low position, is dragged downstream of the fluid current causes the power generator to produce energy and further causes a second floating platform, having the movable paddle in elevated position, be pulled upstream.

Abstract: A power generation apparatus for generating power from water flows is provided. The apparatus has an elongated module having a mechanical side and a hydraulic side, a generator coupled to the mechanical side. The hydraulic side having a set of paddles partially submerged in a water flow. The elongated module has a pivoting point on its mechanical side so that the hydraulic side follows an arc trajectory. The paddles are configured to change positions based on the angular location of the arc trajectory.

Abstract: The present invention relates to submergible modular breakwaters for lowering the kinetic energy of water waves. In particular, the present invention is directed toward a physical embodiment that, when in its floating position, will provide resistance to the movement of water waves in the direction of the waves for a large range of wave periods. The invention is a submergible modular breakwater that can be kept underwater on the sea or lake floor as not to provide any barrier to navigation until it is needed to lower the kinetic energy of waves, when it is quickly raised afloat to provide protection, especially for coastal erosion control during storms or rough waters. Once the lowering of the kinetic energy of water waves is not longer needed, the modular breakwater can be quickly sunk to the sea or lake floor in order to remove any barrier to navigation.

Abstract: A wave energy conversion system or device includes a float and base on top of which there is a power take-off system. The float, its base and the machine room are inserted in a main column supported by legs and corresponding leg supports on the bottom floor in shallow waters (seas or lakes). In deeper waters, the main column may be supported by column supports attached to an underwater float. The machine room is separated of the float frame through a rotary joint which allows the float and base to rotate in any horizontal direction while maintaining the machine room fixed in the same horizontal direction. The rotary joint separating the float frame and the machine room also allows for the vertical up and down movement when interacting with incoming waves. The distance between the machine room and the float frame is always the same. The device includes flaps or blades for the absorption of kinetic energy derived from the back and forth movement of water generated by waves.
