The amount of movement will be equal to the product of the thread pitch and the number of rotations made. It should be noted that the electrical energy generator may be positioned within the internal cavity of the bouy or float, or it may be positioned external, yet still engaged, to the float. The generated electrical energy may be used to power a wide variety of electronic devices including, without limitation, locators, signaling equipment, entertainment equipment, energy storage equipment, radio receivers, radio transmitters, wireless telephones, cameras, global positioning system (GPS) equipment, and like electronic devices. It should be noted that the damping of the energy from the mass may comprise critically damping, greater than critically damping or less than critically damping. A spring pre-load is a load that exists in the spring prior to deflection of the spring from some initial state.

By harvesting mechanical energy from the reciprocating mass and converting it into electrical energy, the device acts as a linear electrical generator. Kinetic energy is the energy of a mass in motion. Retardation of the motion of the electromagnetically active mass may occur by pressure differentials. Pressure differentials may be created by motion of an object within, and in close clearance to, a closed housing. According to embodiments including a closed housing, the housing atmosphere need not be substantially identical to the surrounding external environmental atmosphere. When a driving force is acting on the electrical energy generator, according to certain embodiments, the device behaves as a substantially harmonic driven, damped oscillator. The relationship between the restorative force and the displacement is the spring coefficient. As used herein, pre-load of a spring refers to the load in the spring in the unexcited device in which the electromagnetically active mass is at rest.
