Abstract
An energy harvesting apparatus is deployed on a vehicle and comprises a vehicular shock absorber capable of reciprocating translational movement in response to roadway perturbations. A coil is mounted within the shock absorber. An engine is also mounted within the shock absorber for converting the translational movement into rotational movement. A magnet is coupled to the engine and is configured to be rotated in the vicinity of the coil to produce electrical energy in the coil.
