Abstract: The present invention relates to a plant for recovery and conversion of kinetic energy in bodies of water to mechanical or electrical energy. The plant comprises a float (3), a pump, a weight (10), one or more buoyancy regulators (11), an accumulator tank (14) and a turbine (15), where the pump is composed of a double-acting cylinder pump (6, 7), where a stationary outer sleeve (7) is connected with a water anchor (8), to which a water anchor (8) a weight (10) and the buoyancy regulator(s) (11) are connected, where a movable inner sleeve (6) is connected to the float (3), in order thereby to provide a relative movement between the stationary sleeve (7) and the movable inner sleeve (6) when the float (3) is moved in the bodies of water, where the float (3) is connected via mooring lines (4) with a moored surface buoy (2), so that the float (3) is arranged with a long side against incoming waves (5).
