An appraisal of a Banggood Stirling engine sent for review. Priced at $65.99 this seems extremely good value for what is quite a complex piece of engineering. From applying heat via the small alcohol fueled burner, running operation started quite quickly - around 30 seconds. Running speed is impressive although, in common with this engine principle, actual power developed is predictably modest. As an interest and demonstration machine this is a very nice example and ideal for educating children. |
