Abstract: This invention relates to a wave energy conversion apparatus comprising at least a base, a reciprocating panel, supporting legs and a pivot shaft for the reciprocating panel, and a power-take-off machinery equipped with a generator comprising a rotor, in which apparatus the panel is hinged at its lower edge onto the stationary supporting legs to make a reciprocating motion in response to kinetic energy of waves or tidal currents. The apparatus comprises an actuating mechanism to convert the power of the circumferential speed of the reciprocating panel at a distance point being situated at the area of the upper half of the panel mechanically to a rotational movement of the rotor of the generator of the power-take-off machinery.

Abstract: This invention relates to a submersible wave energy con- version unit comprising at least a stationary stand, a panel hinged at its lower edge onto the stationary stand to make a reciprocating motion in response to kinetic energy of waves or tidal currents, and a power-take-off machinery. According to the invention the power-take-off machinery is placed inside the panel.
