Abstract
Abstract Apparatus for generating electricity including a chamber with a top opening, anchoring mechanism for positioning the chamber in a body of water with wave movement, mechanism for generating an electrical current disposed within the chamber, and mechanism for transferring the electrical current from the chamber; the chamber including first and second sidewall sections spaced from each other over at least a portion of their surfaces, endwall sections connecting the sidewall sections, the sidewall sections and the endwall sections being connected to each other to form a substantially liquid tight chamber, the anchoring mechanism including mechanism for maintaining the first of the sidewall sections remote from the waves and fixed against movement from the action of the waves, the anchoring mechanism including mechanism for anchoring the second of the sidewall sections in the path of the waves while permitting the second sidewall section to be moved by the action of the waves, the generating mechanism including coil mechanism including an electrically conductive wire, magnet mechanism associated with the coil mechanism and movable with respect thereto, the coil mechanism being affixed to one of the sidewall sections and the magnet mechanism being affixed to the other of the sidewall sections, and the transfer mechanism being connected to the coil mechanism, and biasing mechanism urging the second sidewall section away from the first sidewall section against the action of the waves.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
219 words
Apparatus for generating electricity including a chamber, anchoring means for positioning said chamber in a body of water with wave movement, means for generating an electrical current disposed within said chamber, and means for transferring said electrical current from said chamber; said chamber including first and second sidewall sections spaced from each other over at least a portion of their surfaces, endwall sections connecting said sidewall sections, said sidewall sections and said endwall sections being connected to each other to form a substantially liquid tight chamber, said anchoring means including means for maintaining the first of said sidewall sections remote from said waves and fixed against movement from the action of said waves, said anchoring means including for anchoring the second of said sidewall sections in the path of said waves while permitting said second sidewall section to be moved by the action of said waves, said generating means including electrically conductive coil means, magnet means associated with said coil means and movable with respect thereto, said coil means being affixed to one of said sidewall sections and said magnet means being affixed to the other of said sidewall sections, said transfer means being connected to said coil means, and biasing means urging said second sidewall section away from said first sidewall section against the action of said waves.
Claim 2
Dependent Claim
219 words
Apparatus for generating electricity including a chamber, anchoring means for positioning said chamber in a body of water with wave movement, means for generating an electrical current disposed within said chamber, and means for transferring said electrical current from said chamber; said chamber including first and second sidewall sections spaced from each other over at least a portion of their surfaces, endwall sections connecting said sidewall sections, said sidewall sections and said endwall sections being connected to each other to form a substantially liquid tight chamber, said anchoring means including means for maintaining the first of said sidewall sections remote from said waves and fixed against movement from the action of said waves, said anchoring means including for anchoring the second of said sidewall sections in the path of said waves while permitting said second sidewall section to be moved by the action of said waves, said generating means including electrically conductive coil means, magnet means associated with said coil means and movable with respect thereto, said coil means being affixed to one of said sidewall sections and said magnet means being affixed to the other of said sidewall sections, said transfer means being connected to said coil means, and biasing means urging said second sidewall section away from said first sidewall section against the action of said waves.
