Unlike internal combustion engines (gasoline, diesel), it requires \u003cstrong\u003eno explosion\u003c\/strong\u003e or internal combustion — the heat source can be entirely external and of any nature: flame, sun, friction, human heat, and in the case of the low-temperature model, a simple \u003cstrong\u003ecup of hot water\u003c\/strong\u003e.\u003c\/p\u003e\n  \u003cp\u003eThe principle is elegant: when the air trapped in the cylinder comes into contact with the \u003cstrong\u003ehot base\u003c\/strong\u003e, it \u003cstrong\u003eexpands\u003c\/strong\u003e and pushes the piston; when it is then moved to the \u003cstrong\u003ecold\u003c\/strong\u003e zone (top of the cylinder exposed to ambient air), it \u003cstrong\u003econtracts\u003c\/strong\u003e and pulls the piston in the opposite direction. This cycle repeats as long as the thermal difference is maintained, creating a continuous and autonomous rotational movement — fascinating to observe and particularly \u003cstrong\u003eeducational\u003c\/strong\u003e.\u003c\/p\u003e\n  \u003cp\u003eThe ALDABERT-001 is a \u003cstrong\u003e\"low-temperature\"\u003c\/strong\u003e model: while most commercial Stirling engines require a flame or an intense heat source, this model is calibrated to start with only a \u003cstrong\u003e25 °C difference\u003c\/strong\u003e between the base and ambient air — which makes it \u003cstrong\u003esafe\u003c\/strong\u003e, accessible to accompanied children, and usable daily without special equipment.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-des\"\u003e\n  \u003cdiv class=\"t\"\u003eTHE ALDABERT SPIRIT: THE BEAUTY OF THERMODYNAMICS\u003c\/div\u003e\n  \u003cdiv class=\"x\"\u003eFew objects \u003cstrong\u003eembody the fundamental principles of physics as elegantly\u003c\/strong\u003e as the Stirling engine.
