The heating cylinder is specially made thick glass material, long-term heating without pressure Features:The Stirling Engine Principle was invented in 1816 by a pastor Robert Stirling in London, so it was named Stirling engine. The Stirling engine is a unique heat engine because their theoretical efficiency is almost equal to the theoretical maximum efficiency, called the Carnot cycle efficiency. The Stirling engine is powered by the expansion of the gas and the contraction of the cold. This is an external combustion engine in which the fuel is continuously burned, the expanded air (helium ) acts as a medium to move the piston, and the expanded gas is cooled in the cold chamber, and such a cyclic process is repeatedly performed. Only a small alcohol lamp is needed to make it fly fast and powerful. Package included:1x Stirling Generator Model1x English Manual
