1. An energy system for a dwelling, comprising:

  • an inner tank;

    a generator within the inner tank, wherein the inner tank contains a first fluid surrounding at least a portion of the generator, the generator being configured to produce electricity for the dwelling;

    an outer tank having an open cavity that extends between opposite first and second end portions;

    the first end portion of the outer tank containing at least a portion of the inner tank, which is at least partially submerged within a second fluid disposed within the open cavity of the outer tank;

    an exhaust port operably coupled to the generator to receive exhaust fumes from the generator, the exhaust port passing through the second fluid to exchange heat from the exhaust fumes to the second fluid;

    the exhaust port comprising an elongated tube having a crescent-shaped cross section, with opposite end portions and a middle portion, to improve heat transfer from the exhaust fumes to the second fluid;

    the elongated tube being shaped to helically wind along a substantial length of a long axis of the outer tank and positioned such that the middle portion of the crescent-shaped cross section is bowed in an upward direction toward the upper end portion of the outer tank, the elongated tube extending between the generator and an exit port associated with the second end portion of the outer tank such that an exhaust pathway is directed from the generator toward the exit port;

    a fluid outlet operably coupled with the first end portion of the outer tank to deliver the heated second fluid from the outer tank for use by the dwelling; and

    a fluid inlet operably coupled with the second end portion of the outer tank such that an outer tank fluid pathway is directed from the fluid inlet at the second end portion of the outer tank toward the fluid outlet at the first end portion of the outer tank.
