ENJOMOR Hot Air Balance Stirling Engine External Combustion Engine Generator

.With innovative design concept and strict manufacturing, we use the theory of Stirling to build a model that leads kids to knowledge through tangible fun. Heated by alcohol lamp, the model can run quickly with strong power. With mini electric generator to light the LED lamp, the model is unique and exquisite.
.The amazing performance will stimulate inspiration and lead you to a fancy world. With the rotation of the flywheel, you will amazed at the energy transformation and  enter a extended innovative world.
.The body adopts aluminum alloy, the connecting rod and actuating cylinder are made from copper. Silica glass is used in the heating cylinder. The surface of the model is anodized with metallic luster and operate stably. The model combines texture and beautiful.
.Instruction: Place the model on the desktop then add 95% alcohol into the alcohol lamp (less than 2/3 of the capacity). Lighting the alcohol lamp and preheating by the heating cylinder for 30s. Stir the flywheel to start. Do not touch the heating parts to prevent scald. Make sure there is no lubricant on the cylinder and piston.
