  • Method for collecting energy from swell and plant for carrying out said method
    Patent number: 4177643
    Abstract: A method and apparatus for collecting energy from a swell in a fluid medium using a mobile float which is displaceable in response to movements of the swell. The float is submergible in the fluid medium at a predetermined depth selected such that, in the absence of movement of the fluid medium, the upwardly and downwardly directed forces acting on the float counterbalance each other so that the float is in equilibrium at such predetermined depth. The buoyancy of the float is adjusted to maintain it in equilibrium.
