Description
 
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 50C 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!
