TL;DR: In this article, a nearshore wave energy converter (WEC) could withstand the force of an incoming tsunami by using the analytical 3D model developed within the framework of a linear theory and applied to an array of fixed plates.
Abstract: With an increasing emphasis on renewable energy resources, wave power technology is fast becoming a realistic solution. However, the recent tsunami in Japan was a harsh reminder of the ferocity of the ocean. It is known that tsunamis are nearly undetectable in the open ocean but as the wave approaches the shore its energy is compressed creating large destructive waves. The question posed here is whether a nearshore wave energy converter (WEC) could withstand the force of an incoming tsunami. The analytical 3D model of Renzi & Dias (2012) developed within the framework of a linear theory and applied to an array of fixed plates is used. The time derivative of the velocity potential allows the hydrodynamic force to be calculated.

TL;DR: In this paper, a flywheel-generator combination is used to convert the kinetic energy of the wind and the sea waves in the complete width and height of the plant, and is converted across the flywheel in to electric power.
Abstract: The kinetic energy of the wind and the sea waves is utilised in the complete width and height of the plant, and is converted across a flywheel-generator combination in to electric power. The sails are arranged ring shaped. The sails are positioned analogous to a sailing ship travelling in a circle respectively according to the direction of the wind. The sail rotor (2) is seated on its outer rim and is displaced in a rotational movement. The wave paddles (20) are arranged diagonal to the wave front, to make possible a continuous transmission of the different incoming wave forces.

TL;DR: In this paper, an optimal design of an oscillating buoy wave power device is proposed and a model of the device is built and a test is carried out in a wave tank.
Abstract: An oscillating buoy wave power device (OD) is a device extracting wave power by an oscillating buoy Being excited by waves, the buoy heaves up and down to convert wave energy into electricity by means of a mechanical or hydraulic device Compared with an Oscillating Water Column (OWC) wave power device, the OD has the same capture vvidth ratio as the OWC does, but much higher secondary conversion efficiency Moreover, the chamber of the OWC, which is the most expensive and difficult part to be built, is not necessary for the OD, so it is easier to construct an OD In this paper, a nu-merical calculation is conducted for an optimal design of the OD firstly, then a model of the device is built and, a model test is carried out in a wave tank The results show that the total efficiency of the OD is much higher than that of the OWC and that the OD is a promising wave power device
