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. A wave energy conversion system comprising:
a plurality of vibrational linear electric generators (VLEGs), wherein each of said VLEGs includes a field coil array and a permanent magnetic array that is configured to induce an electrical current in said field coil array in response to relative motion effected by waves traversing a fluid medium in which said VLEGs are disposed,
wherein the plurality of VLEGs are configured such that poles of given magnets of a given permanent magnetic array in a given vibrational linear electric generator (VLEG) of said plurality of VLEGs are adjacent to poles of opposite polarity of other magnets of another permanent magnetic array of another VLEG of said plurality of VLEGs that is adjacent to said given VLEG to concentrate a magnetic field through a field coil array of at least one of said given VLEG or said other VLEG.
2. The system of claim 1 , wherein said plurality of VLEGs are arranged in a three-dimensional geometric structure.
3. The system of claim 2 , wherein said geometric structure is a lattice structure.
4. The system of claim 3 , wherein poles of the permanent magnetic arrays that are disposed at corners of the lattice structure have a common polarity.
