A 250-Year-Old Volcanic Device Idea Brought to Life

In the eighteenth century, a unique idea emerged from Sir William Hamilton, the British ambassador to Naples and Sicily, who creatively combined art with early mechanical innovation to design a device that simulates volcanic activity. This idea, which never materialized in his time, found its way to life two and a half centuries later thanks to the efforts of a team of engineering students.

The Origin and Revival of the Idea

Hamilton’s concept was inspired by a 1771 watercolor by British-Italian artist Pietro Fabris, depicting a nighttime scene of flowing volcanic lava. Hamilton’s idea was to use light and motion to mimic glowing lava and volcanic eruptions. Although there is no evidence that the device was built in his era, a detailed blueprint preserved in the Bordeaux Municipal Library provided sufficient guidance for its reconstruction in modern times.

This forgotten idea was revived thanks to Dr. Richard Gillespie, who proposed to bring Hamilton’s device back to life and supervised the completion of the project. He expressed his delight, saying, “It is fitting that our students are reviving this project exactly 250 years later; it is a wonderful piece of scientific communication.”

Modern Engineering Meets Eighteenth-Century Imagination

Engineering students at the University of Melbourne worked on building the device using modern tools such as laser-cut wood, programmable LED lighting, and electronic control systems. This process provided rich learning opportunities for the students, who gained skills in programming, soldering, and physics applications.

Student Shini (Yasmin) Xu shared her experience: “I expanded many skills including programming, soldering, and physics applications.” Meanwhile, student Yuji (Andy) Zheng noted that the experience helped him see mechanical design from a new perspective.

Collaboration and Innovation

Research engineer Andrew Kougios, who guided the students throughout the project, praised their dedication and skills. He explained that collaborating with the students was highly rewarding, emphasizing the importance of these experiences in supporting their university studies and setting them on the right path for future success.

Today, the completed mechanical volcano is on display at the “Grand Tour” exhibition in the Baillieu Library at the University of Melbourne, where it will be exhibited until June 28, 2026.

Conclusion

This experience is a living example of how modern engineering can be combined with historical innovation to revive old ideas and give them new life. The process demonstrated how collaboration and creativity can contribute to the advancement of science and scientific communication in an engaging and effective manner. Working on this project was not just about rebuilding an old device, but an opportunity to develop new skills and broaden the horizons of students in the field of engineering.
