Patent ID: 8715496

Claim:
A system for altering water properties in an outdoor body of water, comprising: a holding vessel configured to hold water, the holding vessel having at least one wall, the at least one wall extending at least above a mean surface water level, the holding vessel having a buoyancy structure that aids in generally maintaining a top of the holding vessel at a desired height above a mean water surface level, and the holding vessel having a wave alteration structure that aids in causing waves impinging on the holding vessel to overtop the top of the holding vessel and the water being captured within the holding vessel creating a pressure head, the pressure head being based on a difference in height between the water in the vessel and the mean surface water level of the body of water, causing movement of the captured water in a downward direction; at least one conduit extending downward from the holding vessel and containing the downward water movement, the at least one conduit having a length extending to a depth at which at least one property of water at the depth differs substantially from that of water at the surface the at least one conduit having an outlet at the depth; at least one aperture formed in at least one of the holding vessel or the at least one conduit and located at a distance below the mean surface water level the at least one aperture separate from the outlet; and at least one one way valve coupled to the at least one aperture and allowing flow of water into the interior of the holding vessel or the interior of the conduit.
