Description: Stirling engine, invented by Robert Stirling, was named after him in 1826. It is a heat engine operating by cyclic compression and expansion of air or other gas, making it a conversion of heat energy to mechanical work With heat resource from the small alcohol burner, the item can be easily operated and used widely as an educational tool or toy for students or children to know the principle of energy conversion in physical demonstration It can also be used as gifts, collections or decorations for youngsters, adults and elders, making it more unique and interesting The Stirling engine is noted for its high efficiency compared to steam engines, because it can use almost any heat sources. This engine is currently exciting interest as the core component of micro combined heat and power units, in which it is more efficient and safer than a comparable steam engine Material: Metal Size Chart: Size: approx. 15.8 x 5.4cm/6.22 x 2.13inch Package Includes: 1 Piece Stirling Generator Model Kits
