A solar pond, including a heat absorbing fluid and an insulating layer disposed above and covering the heat absorbing fluid; wherein the insulating layer includes a body of water and fibers suspended in and dispersed throughout the body of water. The fibers have an density that is approximately the same as the density of the body of water and an index of refraction that is approximately the same as the index of refraction of the body of water. The viscosity of the insulating layer may be increased by adding a thickening agent and/or a gel thereto to thereby further suppress heat convection in the insulating layer. The insulating layer further includes membranes defining baffles or closed cells in the body of water to further suppress heat convection in the insulating layer.
