ABSTRACT:
A heat storage pond comprises a heat storage liquid covered by a non-liquid insulating layer that floats on the liquid and is thick enough to thermally insulate the latter against significant conductive heat loss to an ambient medium above the insulating layer which may be an aqueous or a non-aqueous gel. The medium above the gel may be a layer of water which operates as a heat sink for a power plant whose heat source is the heat storage layer. The power plant may include a heat engine, such as an organic working fluid turbine, which extracts heat from the heat storage liquid, the layer of water above the gel serving as a condenser for the turbine.
