This is another version of a Stirling engine, 'powered' by an Alcohol burner, this is actually an 'External Combusion' engine. The little oil can is actually a burner (note the wick) and the flame is sucked into the cylinder via the port on the side. (hence the name 'Flamelicker' or 'Flame Eater.' It is very interesting to watch this engine run via the action of expansion and contraction.

I HAVE SOLD THIS ENGINE AND NO LONGER HAVE IT IN MY COLLECTION.
