Abstract:
1. An apparatus comprising: a moveable member disposed within a cylinder device; a mechanical linkage in communication with the moveable member; a gas storage unit in fluid communication with the cylinder device through valving; a control system in communication with the valving to allow compressed gas expanding within the cylinder device, to drive the moveable member; an element in fluid communication with a liquid reservoir to introduce liquid for heat transfer with the compressed gas expanding within the cylinder device in an absence of combustion; a second moveable member disposed within a second cylinder device and in communication with the mechanical linkage; and a second element in fluid communication with a second liquid reservoir to introduce liquid for heat transfer with gas within the second cylinder device; wherein the second cylinder device is selectively configurable as a compressor or as an expander, and wherein the second cylinder device is configured to be in selective fluid communication with the cylinder device.
