  • Ocean wave energy converter (OWEC)
    Patent number: 7728453
    Abstract: A device consisting of a container which is partially submerged in the sea which may be buoyant and connected to the seabed with cables or mounted on a platform and whose interior is connected to its exterior via pipes where in response to the passing of waves is filled and emptied through these pipes. The force of the water flowing through the pipes causes turbines to rotate thus generating electricity which may be transmitted to land. These turbines may be turbines which rotate in different directions depending on the direction of water flow or turbines which maintain the same direction of rotation irrespective of the direction of water flow.
