Abstract
The invention provides an energy recovery device comprising a first SMA core housed in a first immersion chamber and adapted to be sequentially filled with fluid to allow heating and/or cooling of the first SMA core wherein a first shaft is adapted to be turned by the SMA core mounted concentrically around said first shaft. The SMA core comprises a plurality of SMA elements to define a module, wherein a plurality of modules are mounted in series and whereby movement of a first module is configured to be input to a second module enabling cumulative rotation of the shaft.
