One of the reasons of the lack of updates on here was the work on the Stirling engine for my university design module. I had a few problems with getting it to run properly, and ran out of time for tweaking at the end, so decided to fit an electric motor. As well as the main engine, I decided to make a cut away version as shown on the left showing the basic operation of a Stirling engine.
The two models won the £50 cash prize as voted for by the 30 odd other groups on the same course!
