Abstract: A system for converting vehicular kinetic energy into electricity includes at least one on-road energy collection sub-system and a transmission sub-system. The on-road energy collection sub-system includes at least one flap lever configured to pivot in response to a vehicle driving thereover, and at least one flap lever shaft coupled to the flap lever such that the pivoting of the flap lever drives movement (rotational and/or translational) of the flap lever shaft. At least one output shaft is coupled to the flap lever shaft such that the output shaft is driven to rotate to provide a unidirectional rotational output in response to the movement of the flap lever shaft. The transmission sub-system is configured to receive the unidirectional rotational output from the output shaft as a rotational input and to selectively modify the rotational input for transmission to a flywheel sub-system.
