Claim Text:
1. A vehicle energy harvester comprising: a subunit having an upper surface forming a roadway surface; a vehicle activated treadle on the subunit, the vehicle activated treadle moveable between a first position in which an upper surface of the treadle is at an angle with respect to the upper surface of the roadway surface and a second position in which the upper surface of the treadle is flush with the upper surface of the roadway surface; a generator that generates power in response to movement of the vehicle activated treadle from the first position to the second position and from the second position to the first position; a reciprocal spring arrangement applying a biasing force on the vehicle activated treadle to move the vehicle activated treadle away from the second position and toward the first position; and a transient absorption device coupled between the vehicle activated treadle and the generator, the transient absorption device absorbing transient forces resulting from one or more movements of the vehicle activated treadle from the first position to the second position and gradually releasing the absorbed transient forces to the generator over a period of time.
