Linear faraday induction generator for the generation of electrical power from ocean wave kinetic energy and arrangements thereof
View Patent ↗Various embodiments of linear electric generators and arrangements thereof are disclosed. One such generator includes a permanent magnetic array with magnets that are oriented such that like poles of the magnets are disposed adjacently to concentrate a magnetic field through a coil array. To enhance the magnetic field distribution, the magnets are affixed under a compressive strain due to repulsive forces resulting from proximity of the like poles. According to another aspect, a plurality of vibrational linear electric generators (VLEGs) can be arranged so that magnets of different VLEGs are oriented so that poles of opposite polarity are disposed adjacently to further enhance magnetic field concentration through coil arrays. In addition, a plurality of wave energy converters can be arranged in very close proximity, at most 8 times a height of a buoyant portion of the converters, to act as a seawall and thereby protect various structures from ocean waves.
1. An electrokinetic seawall system comprising:
a plurality of wave energy converters (WECs), wherein each of the WECs includes a buoyant portion configured to be disposed above a surface of a fluid medium when the WEC is immersed in said fluid medium and wherein each of the WECs is configured to convert mechanical energy of waves traversing the fluid medium into an electrical current, and
wherein said plurality of WECs are affixed such that distances between adjacent WECs of said plurality of WECs are at most 8 times a height of one of said buoyant portions to dissipate the mechanical energy of said waves over an area of said fluid medium.
2. The system of claim 1 , wherein said plurality of WECs are tethered by rigid or flexible connectors to a seawall to dissipate the mechanical energy of said waves that traverse into said seawall.
3. The system of claim 1 , wherein said plurality of WECs are configured to envelop a structure to dissipate the mechanical energy of said waves that traverse into said structure.
4. The system of claim 1 , wherein said plurality of WECs are affixed to each other with elastic connectors.
5. The system of claim 1 , wherein said plurality of WECs are enveloped by and tethered to a semi-enclosed container that is configured to be at least partially submerged within said fluid medium and to be filled with said fluid medium.
6. The system of claim 5 , wherein said container, when disposed in said fluid medium, has a center of mass at a depth below the surface of said fluid medium that is sufficient to render said container relatively stationary when said waves traverse over said container.
7. The system of claim 1 , wherein each of said buoyant portions have a common height (L) and wherein said distances are at most 4 L sine 60°.
