Heat engine invented in 1816 by Scottish clergyman, Robert Stirling. Almost 200 years later we present working desktop replica of the engine. The engine converts heat energy to mechanical work. Now, it is an excellent bcorporate gift idea for business executives.
You can read more about its origin on Wikipedia: http://en.wikipedia.org/wiki/Stirling_engine .
The engine is made of metal and glass. It is covered with 24-carat gold. All you have to do is pour any kerosene lamp fuel into the burner and light the wick. The burner is to be set under the glass piston. The engine will work after a few minutes.
Attention! The engine is packed in a cardboard box, which does not match the elegant character of the product. It is only a shipping packaging.
