    Abstract: The present application relates to the field of energy recovery and in particular to the use of shape memory alloys (SMA) for same. An energy recovery device is provided which comprises a one way drive mechanism for incrementally winding a spring. An SMA engine comprising a length of SMA material is fixed at a first end and connected at a second end to the one way drive mechanism. The SMA engine is housed in an immersion chamber and adapted to be sequentially filled with fluid to allow heating and/or cooling of the SMA engine to enable high frequency contractions and expansion. An output transmission is provided which is coupled to and driven by the spring. In this manner, repeated contractions of the SMA material incrementally wind the spring to store energy. The spring is restrained by a release mechanism which may be activated to allow the spring to drive an output transmission.

    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.

    IPC: F03G7/06

    Abstract: The invention provides an energy recovery system comprising a plurality of Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) elements arranged as a plurality of wires positioned substantially parallel with each other to define a core; a hydraulic chamber in communication with one end of the core and adapted to convert movement of the core into energy; and an energy storage device adapted to provide a lower pressure relative to the pressure in the hydraulic chamber. The invention addresses an unbalance in stress distribution across the SMA bundle that occurs as a result of the mechanism of fluid input into the SMA core. The net effect of the fluid dynamics at the entrance to the core is that SMA wires at the exterior of the bundle activate before wires on the interior of the bundle.

    Abstract: The invention provides an energy recovery device comprising a plurality of Shape Memory Alloy (SMAs) or Negative Thermal Expansion (NTE) elements arranged as a plurality of wires positioned substantially parallel with each other to define a core wherein the wires are selected to have different dimensions such that the plurality of wires are activated at substantially the same time in response to a temperature change.

    Abstract: The application discloses an energy recovery device comprising a drive mechanism; an engine core comprising a plurality of Shape Memory Alloy (SMA) elements or Negative Thermal Expansion (NTE) elements fixed at a first end and connected at a second end to the drive mechanism. A block mechanism is positioned between the engine core and the drive mechanism to restrict movement of the drive mechanism until the elements reach a desired temperature.
