Abstract : This invention pertains generally to the storage of thermal energy and in particular to such storage as latent heat of fusion in a ternary eutectic salt mixture. Storage of thermal energy has gained great importance since the increased interest in the use of solar energy. On account of the fluctuation in electrical usage and the limited availability of the sum during a 24 hour period, a practical solar energy collector requires a large-scale, demand-sensitive energy storage. Otherwise, the solar power system must be connected to an electrical power grid, which accommodates the changing input by means of peaking units. Such units are usually fast response, fuel-fired power generators that are generally of lower efficiency than base-load units.
