Steam engines were the first engines that made heavy work easy for people. However, there were frequent explosions in the steam boilers. That is why many engineers tried to invent less dangerous drives. Almost 200 years ago, the young Scottish clergyman Robert Stirling developed a type of engine that has never been used on a large scale, but is still used in a number of applications.
The little motor is literally constructed from the can in which it came. It is powered by the heat of the tea candle and the air cooling. The principle is really simple, but very sophisticated. A hobbyist needs 2–3 hours to assemble the approximately 150 parts. The detailed instruction manual with precise illustrations guides step-by-step to the complete motor. Only basic tools needed.
