Stirling Engines – harder than they look

Alan gave a very interesting talk on Stirling Engines, and buoyed by his information that they’re very simple and have few moving parts, we tried to make one.

Surprisingly, this didn’t work, possibly due to:
  1. Poor tolerances
  2. Wrong materials (it’s supposed to be a steel can for a better temperature differential)
  3. Patrick
  4. High mechanical friction

In other news, the Ballistics Day approaches, 6th August.  A poster is being prepared, and will be posted on here shortly.
