10 . A method of wheel-based power generation on a cart for transporting commercial products, the method comprising:

rotating at least one wheel, wherein the at least one wheel rotates in multiple directions including a first direction and a second direction opposite of the first direction, and wherein the at least one wheel is coupled to a first shaft such that rotation of the at least one wheel causes rotation of the first shaft;

translating, by a rotation transmitter coupled to the at least one wheel, the rotation of the at least one wheel into the rotation of the first shaft;

causing, by the rotation of the first shaft, rotation of a first gear coupled to the first shaft;

causing, by the rotation of the first gear, rotation of a second gear coupled to the first gear;

causing, by the rotation of the second gear, rotation of a second shaft coupled to the second gear;

enclosing, by a housing, at least a portion of the at least one wheel, rotation transmitter, first gear, second gear, first shaft, and second shaft, wherein the housing includes a first housing portion and a second housing portion coupled to the first housing portion, wherein the first housing portion encloses at least a portion of the at least one wheel, rotation transmitter and first shaft, and wherein the second housing portion encloses at least a portion of the first gear, second gear, first shaft, and second shaft;
