ALDABERT-001 Stirling engine advantages
How does a Stirling engine work?
The Stirling engine is a heat engine invented in 1816 by the Scottish pastor Robert Stirling, which exploits the expansion and contraction of a gas under the effect of a temperature difference. Unlike internal combustion engines (gasoline, diesel), it requires no explosion 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 cup of hot water.
The principle is elegant: when the air trapped in the cylinder comes into contact with the hot base, it expands and pushes the piston; when it is then moved to the cold zone (top of the cylinder exposed to ambient air), it contracts 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 educational.
The ALDABERT-001 is a "low-temperature" model: while most commercial Stirling engines require a flame or an intense heat source, this model is calibrated to start with only a 25 °C difference between the base and ambient air — which makes it safe, accessible to accompanied children, and usable daily without special equipment.

Starting the engine in 4 steps
For best performance: use a very hot cup of water (80-90 °C) just after boiling. Start the wheel in a clockwise direction — this is the nominal operating direction. If the movement becomes irregular after several uses, apply a very small amount of dry graphite lubricant to the glass piston. You can also place the engine on other heat sources: hot water bottle, radiator, slightly heated surface. Anecdote: in cold weather (ambient temperature below 12 °C), you can even run it with the heat of your hand (37 °C) — the 25 °C difference is naturally achieved!
Maintenance: The engine does not require regular maintenance. Wipe the body with a soft, dry cloth to preserve the shine of the stainless steel and the finish of the golden wheel. Avoid prolonged contact with moisture. In case of friction or slowing, apply only dry graphite lubricant (available at model shops) to the glass piston. Store away from dust between uses.
Usage precautions: Never use mineral or vegetable oil as a lubricant — oil would clog the mechanism and irreversibly reduce performance. Use exclusively dry graphite lubricant. The engine is not a toy for young children — it contains moving mechanical parts and comes into contact with a hot source. Adult supervision is recommended for educational use with children. Keep out of reach of very young children.
