A walking beam pumping unit onboard above surface energy harvester and converter invention that can supplement electric power to actuate a reciprocating walking beam pumping unit's prime mover, auxiliary devices, and control devices. In one embodiment, the walking beam pumping unit kinetic energy can assist gravity actuated linear and circular generators attached on the reciprocating walking beam, crank arms, pitman arms, head, and articulated reciprocating counterweight. The electro mechanical devices can switch between generating and motoring and send electric current to a capacitor for distribution. In another embodiment, the walking beam pumping unit kinetic energy can assist a mechanically actuated reciprocating piston linear generator attached to the reciprocating walking beam and foundation. In another embodiment, a circular generator device is attached to the crank arms. Used to supply supplemental power for the lifting and lowering of loads with a reciprocating walking beam pumping unit and auxiliary devices.
