2D view of nitinol’s crystalline structure during cooling/heating cycle

Invented in the early 1959, Nitinol alloys exhibit two closely related and unique properties: shape memory and super-elasticity. Shape memory is the ability of Nitinol to undergo deformation at one temperature, then recover its original, undeformed shape upon heating above its “transformation temperature”. Superelasticity occurs at a narrow temperature range just above its transformation temperature; in this case, no heating is necessary to cause the undeformed shape to recover, and the material exhibits enormous elasticity, some 10-30 times that of ordinary metal.

    1. technically you could hook a generator to the rod of a nitinol engine and use that electricity to cool and/or heat [a] bucket[s] of water, so it is free energy. Sorry.
