Fresh water generation system using coastal atmosphere and ocean water
View Patent ↗This invention is designed to create potentially unlimited commercial fresh water at a significantly reduced cost in relation to existing fresh water creation systems such as sea water desalination. This invention pumps coastal atmospheric air through sealed pipes to ocean water depths (ideally) of approximately 100-305 meters, or (ideally) into the local ocean's thermocline layer. Fresh water condensation occurs inside the sealed air pipes as cold ocean water chills the outside of the pipes. Condensation fresh water flows via gravity to the low point in the sealed air pipes where a powered fresh water pump is located. This powered fresh water pump then pumps the accumulated condensation water to the ocean surface and then on to shore as usable fresh water. The pumped-in air, now dehumidified, is piped to the surface and returned to the atmosphere.
1. A fresh water generation system using coastal atmosphere and ocean or sea water for creating cost effective fresh water for municipal water supplies and irrigation, said system consisting of:
an airflow and condensation pipe for delivering atmospheric air from an ocean shoreline to an ocean depth, returning dehumidified air back to the atmosphere and allowing condensed fresh water to flow to a low point in the system, said airflow and condensation pipe including a reversal at said ocean depth for delivering dehumidified air from the ocean depth to the ocean shoreline,
said airflow and condensation pipe further including a narrow part or airflow restriction after said reversal of said airflow and condensation pipe, with a diameter lesser than the diameter of said airflow and condensation pipe, to slowdown the flow of dehumidified air from the ocean depth to the ocean shoreline, thereby creating airflow hesitation and compression and an air pressure difference compared to the shoreline atmospheric air;
an air pumping facility or at least one pump connected to said airflow and condensation pipe, for pumping atmospheric air into said airflow and condensation pipe and for delivering said atmospheric air from said ocean shoreline to said ocean depth;
a condensed water flow pipe connected to said airflow and condensation pipe at said reversal, and extending in a downward direction to enable flow of condensed water away from said airflow and condensation pipe;
at least one fresh water pump connected to said condensed water flow pipe to receive condensed water accumulated in the airflow and condensation pipe at said reversal and to pump accumulated condensed fresh water to the ocean surface; and
a fresh water pipe connected to said at least one fresh water pump and structured to receive condensed water pumped by said at least one fresh water pump into said fresh water pipe, for delivering condensed water above ocean water surface,
wherein said airflow and condensation pipe is structured on a coastal sea bed, to enable flow of condensed water from atmospheric air travelling towards said reversal of said airflow and condensation pipe, thereby accumulating condensed water at the reversal of said airflow and condensation pipe,
wherein said air pumping facility or at least one pump is structured near an ocean or sea and a steep drop off of said coastal sea bed.
