Abstract: An energy conversion, storage and retrieval device and method, comprising: a susceptor crucible encased in a thermal housing, the susceptor crucible having a bottom wall and one or more side walls extending upwardly from the bottom wall, therein defining a crucible interior which contains a thermal energy storage material; a heat generator powered by an electrical energy source and positioned in close proximity to an outside of the side wall of the crucible so as to be able to heat the energy storage material; a regulated fluid flow circuit in the housing that circulates fluid from a fluid circuit inlet, that is heated and circulated to a fluid circuit outlet as heated fluid; wherein when heated, the energy storage material stores thermal energy, and wherein the thermal energy can be retrieved by conduction through the crucible side wall and into the fluid flow circuit thereby heating the fluid therein.
