One embodiment of an energy-conversion apparatus includes a first container to contain working fluid under pressure, a first heat-transfer component in the first container, a second container to contain fluid under pressure, a second heat-transfer component in the second container, and an energy converter coupled to the first and second containers that performs work in response to a flow of fluid through the energy converter, wherein the flow is motivated by varying a pressure within the first container or within second container (or both) caused by the first heat-transfer component or the second heat-transfer component, respectively, without a need for heat conduction through an exterior surface of either container. An energy-conversion method includes, from within one or both of first or second containers, varying an internal temperature to cause a resultant pressure differential that motivates the fluid to flow between the first and second containers, and performing work as fluid flows through the energy converter between the containers.
