||PCT/UA2013/000076||SIDORENKO, Yuriy||SIDORENKO, Yuriy|
The invention relates to electric machines, specifically to the design of a linear electric generator, which can be used, for example, for converting the energy from water, in particular waves, or the energy from weak and moderate winds into electrical energy. The linear electric generator comprises a housing, in which there are arranged coaxially: a rotor and a stator, with the possibility of the relative translational motion thereof along one axis, which rotor and stator are intended for kinematic connection to the drive of the generator. Furthermore, the stator is manufactured in the form of a winding, which surrounds the rotor with a group of permanent magnets, while the terminals of the stator are intended for connection of a load thereto. In accordance with the invention, the linear electric generator is in the form of a two-piston hydraulic system, in which a cavity in the housing with the stator and the rotor is filled with mineral oil with a high degree of purity and a low level of viscosity, for example transformer oil. The stator is manufactured in the form of a tubular piston from a nonmagnetic material with a three-phase winding fixed thereto and a magnetic contactor, which is formed by a spiral winding consisting of a soft-magnetic wire and a supporting element. The rotor is manufactured in the form a tubular piston from nonmagnetic material with a group of permanent magnets arranged thereon on the outside, which permanent magnets are provided with pole concentrators and two rods mounted coaxially with the rotor at opposite ends of the tubular piston, which rods are intended for kinematic connection thereof to the drive of the generator, while the tubular pistons of the stator and the rotor are fixed to tension springs, which are mounted between the housing and the ends, respectively, of the tubular pistons of the stator and the rotor with the possibility of the oscillation of the latter in phase opposition to one another. The linear electric generator solves the problem of the use thereof for converting energy from water, in particular waves, or the energy from weak and moderate winds into electrical energy. The proposed problem is solved by virtue of providing conditions for the use of a liquid which fills the cavity in the housing of the generator as a structural element of the linear electric generator. Owing to the fact that the liquid is practically incompressible, in the proposed device the simultaneous movement of the stator and the rotor in the liquid in opposite directions is ensured without the use of additional complex mechanisms being required to achieve this.

||PCT/KR2014/001831||CHOI, Nam-Kyu||CHOI, Nam-Kyu|
In the air-cushioned small hydraulic power generating device of the present invention, a stator in a generator linked by means of an upper rotational shaft to a first vertical-axis windmill rotates in a first direction, at which time a rotor in the generator linked by means of a lower rotational shaft to a second vertical-axis windmill and an air-cushioned water wheel rotates in the direction opposite to the rotation of the stator thereby making it possible to increase the rotational force and so enhance the power generation efficiency of the stator and the rotor of the generator, and the present invention can easily be installed in valleys, watercourses, rivers, irrigation water and seawater channels without being limited by the conditions in the place of installation, and, in addition, can generate power by using the flow of water while not destroying the aquatic ecosystem, and can minimise generator breakdown and maintenance costs as the generator is installed so as to float easily on a water surface while the air-cushioned water wheel supports the weight of elements such as the rotational shafts and the generator.

||PCT/BR2014/000127||DALLA COLETTA, Osvaldo||DALLA COLETTA, Osvaldo|
A motor driven by the buoyant force of fluids comprises a mechanical system formed by a tank (17) filled with water or another fluid that is denser than water, a wheel with tubes (1-16) with pistons, hydraulic actuators (18), a rotation shaft (20), an oil storage container (21), an air storage container (22), a hydraulic pump (figure 3), valves (figure 4), air pipes, oil pipes, a brake and an electric battery. This mechanical system is characterised in that it utilises the buoyant force of water or other fluids that are denser than water, transforming the buoyant force into motive power by the following process: during their upward movement, the tubes with pistons (9-15) are filled with air and hence the buoyant force of the fluids acts upon these tubes, pushing them upwards, causing the wheel to rotate and hence providing motive power at the rotation shaft of the wheel. During their downward movement, the tubes with pistons (1-7) are filled with water or with another fluid that is denser than water, and hence the buoyant force does not act upon these tubes. The motive force provided at the rotation shaft of the wheel can be transformed into electric energy by connecting an electric generator to the rotation shaft of the wheel, or the motive force can be put to other uses. The power of this motor results from the quantity and volume of the tubes with pistons, from the length of the wheel spokes and from the density of the fluid used and stored in the tank.

Contemplated mooring systems have one or more primary tethers that extend laterally and to which respective pluralities of independent secondary tethers are coupled that in turn are coupled to floating marine devices, and especially wave energy converters. The primary tethers are coupled to preferably static seabed anchors and will so provide a simple and dynamic mooring system that provides multiple operational advantages while allowing for simple deployment and maintenance.

||PCT/FI2014/050289||SUBSEA-ENERGY OY||SILTALA, Timo|
The invention pertains to energy production by capturing simultaneously water potential (surface height differences due to waves) and kinetic (flow of water due to e.g. waves, tide or streams) energy. The plant can have tidal compensation (2, 3, 22, 23) to avoid energy flux streaming over the plant in high tide, and directional stabilizing arrangement to turn it automatically parallel to wave crests. Surfaces capturing energy from flow have optimized movements to follow speed of water in different depths. Also energy conservation to filter output ripple can be arranged with twin-phase fluid accumulators (51, 55).
