La macchina di Stirling
The construction and working of a simple Stirling motor are reported and its thermodynamic behaviour and yield are analysed. This kind of heat engine is remarkably simple and attractive, owing to its unique property of extracting work from heat sources with differential temperatures as low as 20°C. […]
