Patent ID: 8378511

Claim:
A device that converts kinetic energy of waves of a body of water into electricity, the device comprising: a floating structure that at least partially floats on the body of water, the floating structure responsive to the kinetic energy of the waves; a rod extending through the floating structure; and an electromagnet positioned in the floating structure, and at least partially surrounding a portion of the rod, wherein the electricity is generated in the rod when the electromagnet moves relative to the rod in response to motion of the waves, wherein a magnetic field generated by the electromagnet has a strength that is determined by the amount of kinetic energy of the waves, wherein the device comprises at least one conductive coil assembly that is positioned in the rod, and wherein the electricity is generated in the at least one coil assembly in response to motion of the electromagnet relative to the at least one coil assembly, and wherein the at least one coil assembly comprises: a hub; a plurality of spoke extending from the hub; at least one stem extending from each spoke; and at least one conductive wire arranged as a plurality of coils about the at least one stem.
