A gravitational pumping apparatus for pumping saline fluid, comprising:
- One or more upright support stanchion posts affixed to an axle;
- At least one linear track having at least two spring loaded end stops located on opposite ends of the track;
- Wherein the linear track has a left side and a right side;
- and
- Wherein the center of the linear track is affixed to the superior portion of the axle such that the linear track can rotate around the axle when a gravitational force is exerted upon one distal end of the linear track;
- and
- Wherein when a gravitational force is exerted on one side of the linear track the opposite side lifts along the axis;
- An electrified weight bearing vehicle positioned on top of the linear track and allowed to move back and forth on the track, wherein the electrified weight bearing vehicle being comprised of an EV chassis, a battery, and a solar photovoltaic array;
- Wherein the back-and-forth movement of the electric chassis is limited by the spring-loaded end stops;
- and
- Wherein the back-and-forth movement of the electrified weight bearing vehicle along the track exerts a gravitational force on one end of the linear track such that the track rotates around the axle;
- A single chain having a left end and a right end;
- wherein the left end of the chain is affixed to the left distal side of the linear track, and the right end of the chain is affixed to the right distal side of the linear track;
- A minimum of two chain drive gears, each chain drive gear being coupled to at least one pinion gear;
- Wherein at least one chain drive gear is located on the left side of the apparatus and at least one chain drive gear is located on the right side of the apparatus;
- and
- Wherein the chain is connected to the inferior portion of the chain drive gears such that the motion of the chain rotates the chain drive gear;
- A minimum of two horizontal flat racks, each rack being affixed to at least one piston;
- Wherein at least one horizontal flat rack is located on the left side of the apparatus and at least one horizontal flat rack is located on the right side of the apparatus;
- Wherein when the gravitational pump apparatus is in motion each horizontal flat rack is connected to the inferior portion of the pinion gear such that the rack converts the rotational motion of the pinion gear into linear motion;
- A pre-filtered water reservoir comprised of a pre-filtered water inflow pipe, a minimum of two outlet pipes each comprising at least one inferior flap check valve, a pressure cylinder having at least one discharge pipe, having a superior flap check valve and a reverse osmosis membrane stack;
- wherein the flap check valves allow fluid to move in a distal direction from the pre-filtered water inflow into the pressure cylinder;
- wherein each pressure cylinder contains at least one piston;
- wherein when the gravity apparatus is in motion the piston alternates between creating pressure differentials and forcing fluid out of the chamber in the direction of the superior flap check valve and through a reverse osmosis membrane stack.
