ABSTRACT:
Heat engine having a continuous band of thermally responsive shape memory material disposed in rolling engagement with one or more shafts. Below a transition temperature the band is ductile, but above that temperature the band tends to return abruptly to a shape impressed upon the band by heat treatment. The band is heated above and cooled below the transition temperature at points chosen to produce a force which imparts a rotation to at least one of the shafts.
