Abstract
An energy-recovery device comprises an engine, an immersion chamber, a drive, and a power module. The engine comprises a core comprising a core element that comprises working material, the core element comprising a fixed first end and a second end that is connected to the drive. The immersion chamber houses the engine and is configured to be sequentially filled with fluid to expand and contract the core element. The power module applies a controlled stress to the core element during at least one of a heating phase and a cooling phase of a power cycle carried out by the engine.
