Abstract
A system for combined heat and electric power generation, preferably including a heat reservoir and one or more electric generators, each preferably including a heat source and an energy converter. A method for combined heat and electric power generation, preferably including activating an electric generator, deactivating the electric generator, and/or providing heat from a heat reservoir.
Claims20
A method for combined heat and electric power generation, comprising:
- at a heat reservoir, while a heat reservoir temperature of the heat reservoir is greater than a minimum temperature, heating a fluid;
- providing the heated fluid to an external heat demand element;
- while the heat reservoir temperature is less than a threshold temperature, activating an electric generator thermally coupled to the heat reservoir, wherein, while the electric generator is activated:
- a heat source of the electric generator generates heat and provides the heat to a solid-state energy converter of the electric generator;
- the solid-state energy converter generates an electric power output;
- and
- the solid-state energy converter rejects waste heat to the heat reservoir;
- after activating the electric generator, while the heat reservoir temperature is greater than the threshold temperature, deactivating the electric generator.

A system for combined heat and electric power generation, comprising:
- a heat generator operable between:
- an active mode, in which the heat generator consumes fuel at greater than a threshold rate and generates heat;
- and
- an inactive mode, in which the heat generator consumes fuel at substantially less than the threshold rate;
- a solid-state electric generator comprising a heat input region and a heat rejection region, the heat input region thermally coupled to the heat generator;
- and
- a heated water reservoir thermally coupled to the heat rejection region of the solid-state electric generator, the heated water reservoir defining a cavity configured to store heated water, the cavity defining a water input and a heated water output;
- wherein the solid-state electric generator is configured to:
- accept heat from the heat generator at the heat input region;
- generate an electric power output;
- and
- provide waste heat to the heated water reservoir at the heat rejection region.
