Claim 17:
18. A thermal energy storage system comprising:
a wet tank for holding a liquid heat transfer medium therein;
a dry tank for holding a dry heat-storage medium therein;
one or more circuitous heat exchange conduits each having an inlet of fluidically communicative relationship with an interior of the wet tank, and an outlet of fluidically communicative relation to the wet tank at a point of discrete relation to said inlet, and at least a subset of the one or more circuitous heat exchange conduits passes circuitously through an interior of the dry tank in fluidly isolated relation to the dry heat-storage medium held therein;
one or more pumps in operably installed relationship with said one or more circuitous conduits to circulate the liquid heat transfer medium therethrough in a manner sourced from the wet tank at the inlet of each circuitous conduit, conveyed onwardly and circuitously through the dry tank via said at least a subset of the circuitous one or more circuitous heat exchange conduits, and returned to the wet tank via the outlet of each circuitous conduit; and
an output conduit installed the wet tank for routing of a service fluid through the interior of the tank in fluidly isolated relation to the liquid heat transfer medium held therein for heating of said service fluid by the liquid heat transfer medium;
one or more heating components installed in operable relationship to the wet tank to enable warming of the liquid heat transfer medium held therein; and
at least one input conduit installed the wet tank for routing of an externally heated fluid through the interior of the tank in fluidly isolated relation to the liquid heat transfer medium held therein for heating of said liquid heat transfer medium by said externally heated fluid;
whereby the heat transfer medium is heatable by either one of said one or more heating components and said input conduit, and the one or more pumps are operable to circulate the liquid heat transfer medium, once warmed by one or more heat inputs, through the dry tank is operable to store heat energy in the dry heat-storage medium.
