Precision Twin Cylinder Stirling Engine
New Lower Price
|
This is a new twin cylinder model of the popular precision single cylinder Stirling engines.
They superbly made and a delight to watch. A modified scotch yoke links the mechanisms of
the two cylinders which is mesmerising when in action. The engine can run from just a small
difference in temperature between the top and bottom plates. It can run from the heat from
your hand or from the heat when placed on a warm cup of tea/coffee.
