Work is continuing on a 10 metre high "Man Engine" that will travel through Cornwall this summer to celebrate ten years of UNESCO Cornish Mining Heritage status. In order to get the colossal metal puppet moving, local people will have to sing to it along its journey from Tavistock to Land's End.

Simple Stirling Engine: Perhaps the simplest piston engine ever devised- a single piston powered by a tiny alcohol lamp. Glass components allow a view of the internal workings of this design, and the interesting startup behavior from oscillation to full rotation. Heat engines produce mechanical motion from a difference in temperature- here the piston side is near room temperature (the central aluminum post is an excellent conductor and acts as a heat sink as the gas flows through), and the test
