TL;DR: In this paper, a wave power plant with floating chambers moving relative to each other and following the undulating water surface is described, over which two joint connections are fixed to the floating chambers in a rotating manner.
Abstract: The wave power plant (1) has floating chambers (2) moving relative to each other and follow the undulating water surface (8). A bar element (6) and a kinetic energy receiving energy transformation unit (4) are provided between floating chambers, over which two joint connections (12,14) are fixed to the floating chambers in a rotating manner.

TL;DR: In this paper, a theoretical study of tapping a Love wave in an isotropic microacoustic surface waveguide is given, where the surface Love wave is tapped by partial transduction into a bulk wave at a discontinuity.
Abstract: A theoretical study of tapping a Love wave in an isotropic microacoustic surface waveguide is given. The surface Love wave is tapped by partial transduction into a bulk wave at a discontinuity. It is shown here that, by careful design of the discontinuity, the converted bulk wave power and the radiation pattern may be controlled. General formulas are derived for the calculation of these important characteristics from a relatively general surface contour deformation.

TL;DR: In this article, a floating ocean wave electrical energy generating apparatus extracts the energy from the normal wave motion by using a platform supported at the surface of the ocean by a plurality of buoyant hulls.
Abstract: A floating ocean wave electrical energy generating apparatus extracts the energy from the normal wave motion The apparatus includes a platform supported at the surface of the ocean by a plurality of buoyant hulls A plurality of ramps extend from below the surface of the ocean and receives the action of a wave and channel that wave power to a discharge end that is elevated with respect to the sea level That energy is harvested by allow the water to fall, by gravity, into water turbines to convert that potential energy into rotational movement The rotation of the turbine is coupled to an electrical generator to provide useful power from the apparatus In the preferred embodiment, each ramp is individually adjustable angularly to account for the frequency and strength of the waves at the particular location where the apparatus is sited

TL;DR: In this article, the inertial effects of the gyroscope are activated by the float motion and are used to drive a generator, and the whole system operates in the clean environment inside the float.
Abstract: The extraction of energy from ocean waves has been investigated in Europe since the 1970s. During the research process hundreds of devices have been proposed and a few of them have been built full scale and deployed to the ocean. Unlike other renewable energies, so far there has not been a device standing out to be the most suitable to exploit wave power. One of the practical problems to be solved in a Wave Energy Converter (WEC) is durability in the harsh marine environment. This could be critical if parts of the converter such as turbine rotors or auxiliary floats are needed to move or to react while exposed to seawater and spray. One method to solve the problem is to use a WEC composed just by one sealed floating body carrying a gyroscope. The inertial effects of the gyroscope are activated by the float motion and are used to drive a generator. The whole system operates in the clean environment inside the float. In this work a procedure to design the ISWEC device (Inertial Sea Wave Energy Converter) is outlined. The mechanical equations describing the system are linearized, studied in the frequency domain and used as a mathematical tool in the design process. The method is then applied iteratively to design a scaled prototype model to be tested in the wave tank at the University of Naples. The final version of the prototype model is then scaled up to evaluate the performances of a full scale device.Copyright © 2010 by ASME
