12-Year-old builds nuclear fusion device at home

Teen prodigy achieves fusion breakthrough

A 12-year-old from Dallas, USA has accomplished something extraordinary: building a nuclear fusion device in his home. This isn't a power-generating reactor; it's a meticulously designed physics experiment. Over four years, Aiden McMillan dedicated himself to studying and constructing the device, showcasing remarkable ingenuity and scientific aptitude.

Years of dedicated learning

Aiden McMillan, a seventh-grade student, developed an interest in fusion energy around age eight. He spent two years studying basic nuclear physics, homemade fusion reactor designs, and crucial safety protocols related to high voltage and radiation. This foundational knowledge was critical before moving to the hardware phase.

Building the fusion device

With support from a collaborative space, Aiden transformed his home game room into a makeshift laboratory. He spent the next two years sourcing components, building prototypes, and refining his design. The result is an inertial electrostatic confinement (IEC) fusor – a device commonly used by advanced hobbyists to explore small-scale fusion.

How the fusor works

The device utilizes a vacuum chamber connected to vacuum pumps, high-voltage power supplies, and a deuterium gas inlet. Deuterium gas is introduced at low pressure, and a high voltage is applied between an inner electrode and the chamber wall. This ionizes the deuterium atoms, accelerating them towards the center. Occasionally, these ions collide with sufficient energy to fuse, releasing a neutron. Detecting these neutrons confirms fusion is occurring.

Detecting fusion: neutron detection

Aiden faced challenges like vacuum leaks, electrical discharges, and voltage insulation issues. To confirm fusion, he used a neutron detector placed near the fusor. In a vacuum system, the detector shows a baseline level. During fusion, the neutron count increases, correlating with the device's operational conditions. This increase provides evidence that fusion reactions are taking place within the chamber.

Guinness world records consideration

Aiden McMillan has submitted his project to Guinness World Records for verification of achievable nuclear fusion at 12 years old. The application includes neutron records, photos of the setup, operational specifications, and testimonials from observers. This isn't just a claim; it's a documented process with verifiable measurements and checks.

Significance beyond energy production

While the fusor doesn’t produce net energy – consuming more power than it generates – its significance lies in the knowledge and skills Aiden acquired. He gained expertise in plasma physics, vacuum systems, high-voltage circuit design, radiation detection, and safety protocols – skills comparable to those of a real scientist. This accomplishment highlights the potential of accessible STEM education and maker spaces.
