Abstract: A wave energy generator includes a float for floating on the surface of a body of water. An electrical energy generator that is capable of generating usable electrical energy from the kinetic energy of waves is mounted to or otherwise engaged with the float. The electrical energy generator includes a housing, a coil of electrically conductive material, a reciprocally movable electromagnetically active mass, and springs for connecting the mass to the housing. The electrical energy generator may optionally include spring adjustment means engaged with the housing, means for constraining non-linear motion of the electromagnetically active mass, and/or means of mitigating motion retardation of the electromagnetically active mass within the housing.
Abstract: An electrical energy generator that converts kinetic energy harvested from voluntary motor activity of a human or animal to electrical energy. The electrical energy generator includes a housing, a coil of electrically conductive material, a reciprocally movable electromagnetically active mass, springs connecting the mass to either the housing or to adjustment means engaged with said housing, and, optionally, means for constraining non-linear motion of the electromagnetically active mass, and/or means of mitigating motion retardation of the electromagnetically active mass within any existing housing atmosphere. The electrical energy generator may be associated with a carried item, such as a backpack.
