Aidan McMillan

Likely among the youngest people ever to successfully produce measurable neutron output from a homemade Farnsworth–Hirsch fusor (nuclear fusion) — widely reported while pursuing a Guinness World Records claim (NBC 5 Dallas-Fort Worth, Feb 9, 2026) [estimated superlative — flag for verification].

What they built

Aidan McMillan began building a tabletop nuclear fusion device (fusor) at age 8 during the COVID-19 pandemic, working out of the Dallas Makerspace with a retired laser engineer as mentor. After four years of self-study in nuclear physics and iterative prototyping, he achieved successful nuclear fusion just before his 12th birthday in 2024 — becoming potentially the youngest person in the world ever to do so. He is actively pursuing a Guinness World Record and aims to inspire other young scientists while advancing the case for clean, fusion-based energy.
