ABSTRACT:
A generally cylindrical member which can be used to circulate subsurface water upwardly to mix with the surface water, the surface water being colder than the subsurface water due to its being exposed to the cold air thereabove, the member including an elongated hollow lower portion and an enlarged, partially hollowed out head portion, the enlarged head portion including equally axially spaced apart radial channels extending between the hollowed out interior and the periphery thereof. When the device is submerged sufficiently that the channel outlets will be just below the water's surface, and then the device is rotated by a vertically extending shaft, water will be centrifugally ejected through the channels from the interior of the enlarged head portion to mix with the cold water at the water's surface. At the same time, warmer subsurface water will be sucked into and through the hollow lower portion, thereby creating a flow of warmer subsurface water through the device and to the surface. In one embodiment of the device additional elongated hollow cylindrical members can be telescopically interconnected in a slidable fashion to the elongated hollow lower portion of the generally cylindrical member, the enlarged head portion of the generally cylindrical member can be made buoyant, and the entire device can be constructed so as to be slidable around a vertically extending shaft used to rotate the device, such that the device can accommodate changes in the surface level of the water which occur, for example, in tidewater areas.
