The Heatmobile is a unique heat engine that demonstrates the conversion of heat into mechanical energy. It uses the shape memory alloy Nitinol (~50% Nickel, ~50% Titanium) to spin the propeller.

 

Once Nitinol has been formed into shape at high temperature (about 600° C) and allowed to cool to room temperature, it can be easily deformed. However, when heated above a transition temperature (in this application about 50°C to 70° C) the Nitinol object abruptly returns to its high-temperature shape with substantial force. The Heatmobile uses a closed loop of Nitinol wire to drive the two connected wheels and amazingly turn the propeller when put into hot water!
