Low Temperature Differential Stirling Engine: Introduction
For my school science fair, I decided that I wanted to make something that would also help me improve my machining skills. I made a Low Temperature Differential Stirling Engine as designed by James R. Senft in his book “An Introduction to Low Temperature Differential Stirling Engines.” This engine is a closed cycle engine (meaning no air goes in or out) that runs off minor changes in heat, such as the heat of a cup of coffee or a bucket of ice.
Here is a photo of the raw materials I started with:
