A neat next project (as if I need one!)

We spent the day at OMSI and that has enticed me to do something nerdy. If I had another day to kill, I think I would like to build a simple Sterling engine. I remember my friend Seth McNeill has one he made using soup cans and steel wool. Such things would make a great science fair project! After looking hither and yon for other promising designs, I found a website from an freshman engineering class in 2004 that built them in teams. It is funny when looking at their videos to see various methods of additional heat generation to keep things running smoothly.
