Sometimes miniature engines are installed in miniature vehicles or boats.

 

The miniature-engine hobby appears to me to be an outgrowth of the model engineering hobby from a century ago or more, where engines were powered by steam.  Craftsmen made parts from scratch, and later raw castings were made available.  Later still one could order plans and raw castings to make 1/4 scale I.C. engines, often of aircraft of nautical design.  Inline-four engines were popular.

 

Over the years, I have been to model engineering events, and it's always fascinating and educational to see these machines in action.  For as long as I can remember my family has been involved in a club that runs miniature trains large enough to ride on, often built from scratch and running on steam.  Operating miniature steam stationary engines have been exhibited, and the craftsmanship is always amazing.

 

So in reference to the original post from two years ago, what's more impressive, a fully-functioning miniature engine that may be demonstrated to the public, or one made from bits of plastic glued together that most people won't even get to see?  :-P
