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.
