Abstract:
1. An apparatus for storing electrical energy, comprising: (a) a trailer operable to be towed behind a vehicle wherein the trailer comprises: (b) a ring and a pinion gear engaged with the wheel axle and supported by the housing, wherein the ring and pinion gear is supported by the housing such that the center of mass for the housing is proximate to the center of the axle, wherein the pinion comprises a first end and a second end, wherein the first end of the pinion is engaged with the ring, wherein the pinion is positioned substantially perpendicular to the wheel axle, wherein the rotation of the wheel axle is operable to cause rotation of the pinion via the ring; (c) a first pulley engaged with the second end of the pinion, wherein the first pulley comprises a diameter length, wherein the rotation of the pinion is operable to rotate the first pulley about the second end of the pinion; (d) a second pulley, wherein the second pulley comprises a diameter length, wherein the diameter length of the second pulley is smaller than the diameter length of the first pulley; (e) a belt engaged to the first pulley and the second pulley, wherein the rotation of the first pulley is operable to translate into movement of the belt, wherein movement of the belt is operable to rotate the second pulley; (f) an alternator coupled to the shaft, wherein the alternator comprises an input shaft having an exposed end, wherein the input shaft extends in a direction parallel to the pinion, wherein the exposed end of the input shaft is engaged with the second pulley, wherein rotation of the second pulley is operable to rotate the input shaft, wherein the smaller diameter length of the second pulley allows the input shaft to be rotated within an optimum rotation range; (g) at least one battery in electrical communication with the alternator to receive a charge wherein the at least one battery is positioned within the lower deck of the trailer, and (h) an inverter in electrical communication with the at least one battery, wherein the inverter is supported by the receptacle area.
