Abstract:
1. A wave energy conversion device for converting wave energy within a wave medium into electrical energy, comprising: a base connected to a wave-medium floor; a tidal platform moveably connected to the base and a tidal float connected to the tidal platform such that the tidal platform moves vertically relative to the wave medium floor and having a first response time for movement of the tidal platform in response to changes in the distance between the wave medium floor and the wave medium surface; an axle connected to the tidal platform and extending upward proximate to the surface of the wave medium; an inductive coil positioned proximate to the axle, such that an axis of the inductive coil is substantially parallel to the axle; a magnetic sleeve including a magnetic sleeve opening and disposed slidingly about the axel, such that the axle passes through the magnetic sleeve opening; and a float member interfaced with the magnetic sleeve, the float member moving vertically relative to the wave medium floor in response to a wave moving through the wave medium and having a second response time for movement of the float member in response to changes in distance between the wave medium surface and the tidal platform; and wherein wherein a wave moving through the wave medium causes vertical displacement of the float member such that the magnetic sleeve moves relative to the inductive coil and generates electrical energy within the inductive coil, the first response time being greater than the second response time.
