Making Work: Demonstrating Thermodynamic Concepts with Solar-Powered Wax and Rubber Heat Engines
Appleyard, S. J.
Physics Education, v42 n6 p612-620 Nov 2007
Construction details are provided for simple heat engines that use candle wax and elastomers as working substances. The engines are constructed using common household materials and can be easily constructed in a school classroom or at home. They work reliably and are useful tools for demonstrating the conversion of heat to mechanical work. They illustrate that functional engines do not have to be the product of high-precision machining in specialist workshops, but can be constructed from simple materials and simple tools without requiring any special skills. (Contains 8 figures.)
