Abstract
A car wash system including a hydraulic pump, the pump being overcapacity for the rotating cleaning elements to which it is connected. An output from the hydraulic pump is connected to a hydraulic motor, which is, in turn, connected to a generator. The generator is connected to a service panel. Thus, some of the spare capacity of the hydraulic pump may be used to generate electricity which may be returned to the grid, reducing operating costs of the automated car wash.
