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 drive gear mounted on a rotatable shaft, the drive gear being driven by movement of the vehicle activated treadle, and wherein the rotatable shaft is coupled to the generator; and
a transient absorption device coupled between the drive gear and the generator.

7. A vehicle energy harvester comprising:
-
a plurality of subunits each having an upper surface forming a roadway surface; a plurality of vehicle activated treadles on the plurality of subunits, each of the plurality of vehicle activated treadles 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; and a plurality of generators that generate power in response to movement of each of the plurality of vehicle activated treadles, wherein at least one generator of the plurality of generators generates power in response to movement of one of the plurality of vehicle activated treadles from the first position to the second position and from the second position to the first position; a plurality of drive gears mounted on a plurality of rotatable shafts, at least one of the plurality of drive gears being driven by movement of one of the vehicle activated treadles, and wherein at least one of the rotatable shafts is coupled to at least one of the generators; and a transient absorption device is coupled between at least one of the drive gears and at least one of the generators. - View Dependent Claims (8, 9, 10, 11, 12)
