At 12 Years Old, Jackson Oswalt Built a Fusion Reactor in His Bedroom

Like something out of a sitcom or movie. Every kid dreams big, and some turn those dreams into reality. In 2018, 12-year-old Jackson Oswalt built a functional fusion reactor in his bedroom, an impressive feat that caught the attention of the FBI. With this accomplishment, Oswalt also secured a spot in the Guinness World Records.

Although Oswalt enjoyed video games, he wanted to achieve something greater. His nuclear fusion ambitions started after reading about how the teenager Taylor Wilson built a working fusion reactor at home. Oswalt's goal was to become the youngest person to achieve nuclear fusion, and he learned how to do it by watching YouTube videos and online lectures and reading scientific forums.

He built the vacuum chamber and bought components from eBay to create the fusor that generates plasma. Oswalt fused two deuterium atoms on January 18th, 2018. The Fusor.net scientific community confirmed his accomplishment, making him the youngest person to achieve nuclear fusion at home.

This project caught the FBI's attention. They set foot at the Oswalt's residence with Geiger counters, ensuring radiation didn't leak. After inspecting the neighborhood, the FBI discovered no leaks, which also meant Oswalt wouldn't be detained for his efforts.

The Guinness World Records recognized Oswalt's success in 2020, setting his name in the books. Since then, he began working for Midjourney, an AI specialization research lab, and his role involves designing sophisticated hardware interfaces.

Although Oswalt's fusion reactor isn't energy-efficient yet, it still serves as a stepping stone to help fight climate change, demonstrating our ability to solve global issues. This project inspires people to come up with innovations that could change the world.

    Indeed.  When I first heard about him it was before he died... so there was a period of time where his story was simply a bit of quirky folklore... but his life did take a very tragic turn in the end.

    I remember the jokes of how Fidel Castro was renewing his subscription to Popular Science in hopes that Hahn's reactor would be a published article.  I didn't know the rest of the details.

    Wow.  Didn't know about that joke.  There was always something touching and strangely inspiring about an under achieving kid taking on a project like that... but yeah, hard to reconcile those original feelings with the aftermath.
