The hot air engine was invented in 1816 and since that time it has not lost its attractiveness. This Stirling model H50 by Wilesco revives this fascination inspite its small size. Only by heating and cooling of the air thermal energy is transformed into kinetic energy. The engine is fixed on a significant wooden plate and requires merely the special Wilesco beeswax candle light (item no. 01435) for its operation.
