Thermobile: Nitinol wire loop heat engine- the memory wire forcibly straightens out when heated (contact with heat conducting smaller wheel) causing the wheels to spin and providing mechanical kinetic energy from a cup of warm tea water. Nitinol wire is a special alloy of nickel and titanium that can be trained to a specific shape at high temperature- bend it up at room temperature and it will snap back into shape when exposed to moderate heat such as hot water. This remarkable property is a typ

Nitinol : Shape memory alloys Nickel titanium, also known as Nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. Different alloys are named according to the weight percentage of nickel, e.g. Nitinol 55 and Nitinol 60. Nitinol was developed by the U.S. Navy and stands for nickel titanium alloy. This metal is particularly useful for medical applications because it has thermal memory. This property allows stents to be made at a c
