PURPOSE:To provide a solar pond which is not subject to second diffusion or a change in the environmental conditions and which does not produce reduced function by making discontinuous the concentration distribution on the boundary of a convection flow layer and a non-convection flow layer and making the concentration at the lower section of the convection layer a little lower than the concentration at the non-convection layer. CONSTITUTION:The liquid concentration at the lower section of a non-convection flow layer 2 is made a little lower than that at the upper section of a convection flow layer 1. Because of this the liquid specific gravity at the lower section of the non-convection layer is a little smaller than that of the upper section of the convection flow layer, so that, even if the liquid 9 in the upper section of the convection flow layer moved downwards, the liquid 11 in the lower section of the non-convection flow layer does not follow the liquid 9. Consequently there is no mixture of the convection flow layer and the non-convection flow layer, and it is possible to suppress the phenomenon of a movement of the boundary face between the convection flow layer and the non-convection flow layer accompanying a decrease in the liquid concentration in the convection flow layer and it is also possible to prevent thoroughly reduced function of a solar pond. |
