An energy apparatus that stores and disperses energy, the energy apparatus including: (1) an energy object that experiences movement so as to store kinetic energy in the energy object, the energy object including a magnet assembly through which electrons are driven resulting in electric output from the magnet assembly, and the electric output dependent on experienced EMF (electro-motive force) that is experienced by the magnet assembly; (2) a supporting structure that supports the energy object while providing for the movement of the energy object; (3) a first tuning magnet that is supported adjacent the energy object, the first tuning magnet positionable throughout a range of positions, the positions including a first position and a second position; (4) a second tuning magnet that is supported adjacent to the energy object.
