US US12398711B1
A gravity-driven energy pump apparatus and method for reverse osmosis desalination utilizing the gravitational force of an electrified weight-bearing vehicle. Comprised of upright support stanchion posts, an axle, and a linear track with protective end stops located on opposite ends. Wherein the central section of the track is affixed to the axle, enabling rotation when gravitational force is applied, thus tilting the opposite side on the axle. Further comprises an electrified weight-bearing vehicle (EWBV) positioned atop the track allowed to move back and forth, exerting gravitational force and inducing rotation. A solar PV array is affixed to the top of the EWBV to generate solar energy to power the battery. Chains affixed to both ends of the track catch the falling weight of the track. The action rotates drive and pinion gears to push pistons into pressure cylinders, facilitating fluid pumping between pressure cylinders and a pre-filtered water reservoir.
