Memory Metal Engine Driven by Hot Water
The Heatmobile is a very special kind of heat engine that demonstrates the conversion of heat into mechanical energy. This assembly kit includes all component parts for the supporting structure. Glass tumbler and water not included
Heatmobile uses the unique property of Nitinol alloy (~50% Nickel, ~50% Titanium, the "nol" at the end of Nitinol refers to Naval Ordnance Laboratory in Maryland where this alloy has been developed) called the "memory effect". Once Nitinol has been formed into shape at high temperature (about 600º C) and allowed to cool to room temperature, it can be easily deformed. However, when heated above a transition temperature (in this application about 50ºC to 70º C) the Nitinol object abruptly returns to its high-temperature shape with substantially more force than that required to deform it when cold. Heatmobile uses a Nitinol wire formed to a closed loop that drives the two connected wheels.
This assembly kit includes all component parts for the supporting structure. Glass tumbler and water not included.
For ages 14+.
