A method and means of preventing heat convection in a solar pond is disclosed with the means comprising a liner element adapted to cover the sides and floor of a solar pond with the liner element having a bottom portion corresponding to the floor of the pond and side portions corresponding to the sides of the pond and a plurality of membrane elements extending between the sides of the liner element and sealably connected thereto so as to form a plurality of liquid layers with each said layer being fluidly sealed from the immediate adjacent layers and the membrane elements being of a transparent film material. The method of preventing heat convection comprises providing a body of liquid supported on a bottom support surface and having a closed periphery and upper surface, providing a plurality of closely spaced horizontal membranes in the body of liquid with the membranes being a transparent film material, sealing each membrane at the periphery of the body of liquid to prevent migration of liquid upwardly past the membranes, imposing a closed conduit through the liquid adjacent one of the lowermost membranes, and moving a fluid through the conduit whereby the fluid will absorb heat from the liquid by conduction through the conduit. An alternate embodiment of the means for preventing convection is disclosed comprising a liner element and a membrane element extending between the sides of the liner element and sealably connected to the liner element with the membrane adapted to form an upper insulating layer and a plurality of solution filled capsules adapted for dispersion within the insulating layer with the capsules and the solution being transparent.

A method of preventing convection of heat in a fresh water solar pond, comprising, providing a body of fresh water supported on a bottom support surface and having a closed periphery and an upper surface, providing at least three closely spaced horizontal membranes in said body of water; said membranes being a transparent film material, sealing each membrane at the periphery of said body of water to prevent migration of water upwardly past said membranes, whereby water heated by the sun underneath the lowermost membranes will not move upwardly past any membrane, imposing a closed conduit through the water adjacent one of the lowermost membranes whereby said water will not have access to the interior of said conduit, and moving a fluid through said conduit whereby said fluid will absorb heat from said water by conduction through said conduit, the index of refraction of said membranes being substantially that of said water. An apparatus for preventing heat convection in a solar pond, comprising, a liner element covering the sides and floor of a solar pond, said liner element having a bottom portion corresponding to the floor of the solar pond and side portions corresponding to the sides of the solar pond, a membrane element extending between said sides of said liner element and sealably connected to said liner, said membrane forming an upper insulating layer of pond liquid and a lower convecting layer of pond liquid, said insulating layer being fluidly sealed from said convecting layer, and a plurality of capsules filled with a solution and dispersed within said insulating layer, said capsules and said solution being transparent and said solution being denser than the pond liquid so that said capsules are submerged within said upper insulating layer, the index of refraction of said capsules and said solution is substantially that of the pond liquid.
