1. A gravity fluid driven wheel system for generating electricity, the system comprising:

  • a double wheel assembly comprising two identical wheels spaced apart mounted in a vertical orientation on a horizontal axle with a low friction pivoting connection, the two wheels balanced evenly relative to the horizontal axle for a smooth rotation about the horizontal axle;

    a series of struts evenly spaced around the perimeters of the two wheels, between the two wheels interconnecting the two wheels;

    a series of fluid receptacles each having a single opening for admitting a fluid into the fluid receptacle with the fluid receptacle in an upright position and the single opening allowing fluid to flow out of the fluid receptacle with the fluid receptacle in an inverted position, the fluid receptacles all mounted to the struts in an equal spaced array between the two wheels adjacent to the perimeters of the wheels, the fluid receptacles mounted tangentially to the wheels with all of the openings oriented in the same direction so that a measured quantity of fluid poured into a series of the fluid receptacles adjacent to a top of the wheel assembly causes rotation of the wheel assembly due to the weight of the full fluid receptacles on a first side of the rotating wheel assembly and the fluid receptacles empty adjacent to the bottom of the wheel assembly as the fluid receptacles tip to allow the fluid to pass out of the openings leaving all empty fluid receptacles on the second side of the wheel assembly so that the weight of the full fluid receptacles on the first side causes a rotation of the wheel assembly;

    at least one fluid pumping plunger assembly comprising at least one plunger pump immersed in a fluid;

    at least one lever arm mounted on a fulcrum point for driving the at least one plunger pump;

    at least one plunger assembly wheel contacting the wheel assembly so that a rotation is imparted to the at least one plunger assembly wheel in response to the rotation of the wheel assembly;

    a first end of the at least one lever arm attached to the at least one plunger assembly wheel by an eccentric pivotal connection so the first end of the lever arm pivots up and down in response to the rotation of the at least one plunger assembly wheel on a first side of the fulcrum point so that a second end of the at least one lever arm pivots up and down to drive the at least one plunger pump on a second side of the fulcrum point;

    at least one fluid conduit attached between the plunger pump and at least one fluid spout adjacent to a top of the wheel assembly positioned above the opening in each of the fluid receptacles to fill each of the fluid receptacles on the wheel assembly as the opening in the fluid receptacle passes under the at least one fluid spout, the at least one fluid conduit attached to the at least one plunger pump by a one-way flapper valve, the at least one plunger pump and the fluid conduit configured so that each motion of the at least one lever arm pumps a specific quantity of fluid into the at least one fluid conduit to fill a fluid receptacle on the wheel assembly through the at least one fluid spout and the flapper valve prevents flow of the fluid in the fluid conduit back into the plunger pump;

    an electricity generating assembly comprising at least one armature rotatable between at least one pair of magnets to create an electric current in the at least one armature and at least one generator drive wheel connected to the at least one armature by a means to cause a rotation of the at least one armature between the at least one pair of magnets, the at least one generator drive wheel contacting the wheel assembly so that the rotation of the wheel assembly causes the at least one generator drive wheel to create a rotation of the at least one armature to generate an electric current in the at least one armature; and

    a means for conducting the electric current away from the at least one armature for use of the electric current.
