This invention relates to coastal management solutions and sustainable energy generation. This placement advantageously reduces the chance of wave splash arising from larger than normal wave conditions (e.g. In addition, many known wave power generation systems must be built to withstand the large and unpredictable forces to which they are subjected from ocean waves. For example, ocean power generating systems are commonly required to withstand the forces associated with the large waves of “once in a hundred year storms”. The magnitude of the forces in these extreme cases is many times that of the forces arising in most storms and, as such, significant additional costs are necessarily incurred when manufacturing, installing and maintaining the system. In addition, many prior wave power generation systems are heavily reliant upon the direction of travel of the prevailing ocean wave. In certain embodiments, the angled or sloped portion may comprise one or more segments arranged to provide the relatively gradual change in direction between the first segment and the second segment.
It is yet still a further advantage of at least a preferred embodiment of the present invention to provide an ocean wave energy extraction system which reduces the visual impact on the surrounding environment. It will also be appreciated that embodiments of the present invention may be used in newly constructed costal management structures, or retrofitted to existing breakwater structures, jetties, marinas, docks and the like which can serve as a base structure. 4 and 5) for vehicular access along the breakwater (preferably along the entire length of the breakwater) and/or a pathway for light traffic access such as light vehicles and pedestrians.

In other embodiments, one surface of the aerofoil has a concave profile and the opposing surface is convex. In preferred embodiments, the flow control segment includes an angled or sloped portion (e.g. In certain preferred forms, the length of the duct is in the range of about 25% to 45%, more preferably approximately 37%, of the wavelength of the prevailing waves. In some particularly preferred form, the length of the duct may be one of approximately 10m, 15m, 20m, 25m, and 30m. Ejercicios para quitar dolor de espalda . It will be appreciated that the duct is not limited to these specific examples, but may be any suitable length appropriate for the intended application (including the nature of the surrounding environmental conditions and wave climate) of the energy extraction system.
It will be appreciated that the inner cross-sectional area of the duct may be any suitable shape, including irregular shapes and may vary in size and shape along the length of the duct or along each respective segment. It will be appreciated that such on-shore construction enables significant reduce in manufacturing costs compared to offshore manufacturing.

The embodiment provides advantages in terms of simplicity of construction and ease of use. The illustrated embodiment of the system 1 the turbine 9 forms part of a combined turbine and generator unit 10 which operates with a permanent magnet generator. Preferably, the permanent magnet generator includes one or more permanent magnets arranged on one or more of the turbine rotor blades. The telescopic configuration of the first segment may include a plurality of portions, such as tubes, arranged to facilitate relative sliding movement of the tubes. The plurality of ducts may be arranged along a common axis. In certain embodiments, the longitudinal axis of the lower limb of the duct is arranged to extend at a predetermined angle between directions perpendicular and parallel to the longitudinal axis of the base structure. In some embodiments, the base structure is arranged to extend at a predetermined angle between 0 and 90 degrees relative to the direction of the prevailing wave direction.

The angled or sloped portion preferably extends at an angle so as to produce a relatively smooth and gradual change in direction of the oscillating water column (i.e. The duct 3 extends from the foundation 15 to a point above the surface of the water and above the highest predicted wave height for the wave climate of the particular region.

The shutter is preferably in communication with the sensing means such that signals from the sensor are used to move the shutter to tune the resonant frequency of the duct to correspond with that of the current wave conditions. Each pair of telescopic segments may have a locking means to lock the tubes relative to one another to set the desired length of the first segment of the duct. For example, the length of the ducts may increase along the array with the duct closest to shore being the shortest and the duct further from shore being the longest, or vice versa. The intermediate ducts preferably increase in length in a stepwise manner from duct-to-duct along the array. As shown in Figures 1-3, 7A-7B, the passageway from the OWC duct 3 to the turbine/generator unit is significantly smaller than the cross-sectional area of the vertical limb of the OWC duct.
Preferably, the lower limb of the duct defines an inlet opening and the upper limb forms an outlet opening. Advantageously, various embodiments of the breakwater base structure may be positioned or installed either in deep or shallow water and be formed of materials which cause little or no environmental hazards. The ocean wave energy extraction system can be advantageously incorporated into a rock formed breakwater base structure or seawall. The breakwater preferably has a core which is protected by a toe mound formed of smaller rocks, and may comprise a scourge protection layer installed to prevent any scourge.

In some embodiments, the base structure may form at least part of a housing for a desalination plant which is coupled to the wave energy converter to produce fresh water. The duct is preferably located in a body of water such as an ocean, whereby the water column oscillates in response to the rise and fall of waves which reach the wall of the base structure and/or pass the duct. 3athe body of water (e.g.

The duct 3 amplifies the amplitude of each ocean wave passing the ocean wave energy extraction system 1 such that the amplitude of the oscillations of the oscillating water column 4 within the duct is greater than the amplitude of the passing ocean waves. The bracing preferably stops before the flow control segment so that the water in each passage converges into a single flow passage defined by the flow control passage and the vertical duct segment. In some embodiments, there may be two vertical bracing elements, preferably spaced evenly across the width of the duct, to thereby effectively provide three passage ways in or along the first horizontal duct segment. Dolor muscular abdominal izquierdo . In other embodiments, the inner surface may be rounded or curved and the outer surface may be flat to provide the angled or sloped characteristic configuration to the flow control segment.
