Abstract:
1. A water extraction and purification system, comprising: at least one water lifting unit that is configured to fluidly communicate with a groundwater source, the water lifting unit including a water collector having an interior volume that is structured to retain a volume of the water, the water collector having a closed bottom and an open top, at least one upper lift tube extending through the open top into the volume and configured to remove water from the water collector, and at least one lower lift tube extending through the closed bottom into the volume and configured to communicate water to the water collector, and a gas generator that is fluidly coupled to the at least one water lifting unit and configured to generate a gas that buoyantly moves water from the groundwater source and purifies the water as the water is buoyantly moved to a water consumer, wherein the buoyant movement of the water is a sole transport mechanism, and further wherein the gas is introduced into the lower lift tube and into the upper lift tube, the gas generator further comprising a water purification device that is configured to introduce a water purification agent into the gas at a predetermined rate to controllably release at least one of ozone, chlorine, a compound of chlorine, hydrogen peroxide, and a halide-based compound into the gas.
