The Boy Who Played With Fusion
Taylor Wilson always dreamed of creating a star. Now he’s become one
“Propulsion,†the nine-year-old says as he leads his dad through the gates of the U.S. Space and Rocket Center in Huntsville, Alabama. “I just want to see the propulsion stuff.â€
A young woman guides their group toward a full-scale replica of the massive Saturn V rocket that brought America to the moon. As they duck under the exhaust nozzles, Kenneth Wilson glances at his awestruck boy and feels his burden beginning to lighten. For a few minutes, at least, someone else will feed his son’s boundless appetite for knowledge.
Then Taylor raises his hand, not with a question but an answer. He knows what makes this thing, the biggest rocket ever launched, go up. And he wants—no, he obviously needs—to tell everyone about it, about how speed relates to exhaust velocity and dynamic mass, about payload ratios, about the pros and cons of liquid versus solid fuel. The tour guide takes a step back, yielding the floor to this slender kid with a deep-Arkansas drawl, pouring out a torrent of Ph.D.-level concepts as if there might not be enough seconds in the day to blurt it all out. The other adults take a step back too, perhaps jolted off balance by the incongruities of age and audacity, intelligence and exuberance.
As the guide runs off to fetch the center’s director—You gotta see this kid!—Kenneth feels the weight coming down on him again. What he doesn’t understand just yet is that he will come to look back on these days as the uncomplicated ones, when his scary-smart son was into simple things, like rocket science.
This is before Taylor would transform the family’s garage into a mysterious, glow-in-the-dark cache of rocks and metals and liquids with unimaginable powers. Before he would conceive, in a series of unlikely epiphanies, new ways to use neutrons to confront some of the biggest challenges of our time: cancer and nuclear terrorism. Before he would build a reactor that could hurl atoms together in a 500-million-degree plasma core—becoming, at 14, the youngest individual on Earth to achieve nuclear fusion.

Willis says that when Taylor first contacted him, he was struck by the 12-year-old’s focus and forwardness—and by the fact that he couldn’t plumb the depth of Taylor’s knowledge with a few difficult technical questions. After checking with Kenneth, Willis sent Taylor some papers on fusion reactors. Then Taylor began acquiring pieces for his new machine.
Through his first year at Davidson, Taylor spent his afternoons in a corner of Phaneuf’s lab that the professor had cleared out for him, designing the reactor, overcoming tricky technical issues, tracking down critical parts. Phaneuf helped him find a surplus high-voltage insulator at Lawrence Berkeley National Laboratory. Willis, then working at a company that builds particle accelerators, talked his boss into parting with an extremely expensive high-voltage power supply.
With Brinsmead and Phaneuf’s help, Taylor stretched himself, applying knowledge from more than 20 technical fields, including nuclear and plasma physics, chemistry, radiation metrology and electrical engineering. Slowly he began to test-assemble the reactor, troubleshooting pesky vacuum leaks, electrical problems and an intermittent plasma field.
Shortly after his 14th birthday, Taylor and Brinsmead loaded deuterium fuel into the machine, brought up the power, and confirmed the presence of neutrons. With that, Taylor became the 32nd individual on the planet to achieve a nuclear-fusion reaction. Yet what would set Taylor apart from the others was not the machine itself but what he decided to do with it.
While still developing his medical isotope application, Taylor came across a report about how the thousands of shipping containers entering the country daily had become the nation’s most vulnerable “soft belly,†the easiest entry point for weapons of mass destruction. Lying in bed one night, he hit on an idea: Why not use a fusion reactor to produce weapons-sniffing neutrons that could scan the contents of containers as they passed through ports? Over the next few weeks, he devised a concept for a drive-through device that would use a small reactor to bombard passing containers with neutrons. If weapons were inside, the neutrons would force the atoms into fission, emitting gamma radiation (in the case of nuclear material) or nitrogen (in the case of conventional explosives). A detector, mounted opposite, would pick up the signature and alert the operator.
He entered the reactor, and the design for his bomb-sniffing application, into the Intel International Science and Engineering Fair. The Super Bowl of pre-college science events, the fair attracts 1,500 of the world’s most switched-on kids from some 50 countries. When Intel CEO Paul Otellini heard the buzz that a 14-year-old had built a working nuclear-fusion reactor, he went straight for Taylor’s exhibit. After a 20-minute conversation, Otellini was seen walking away, smiling and shaking his head in what looked like disbelief. Later, I would ask him what he was thinking. “All I could think was, ‘I am so glad that kid is on our side.’ â€
For the past three years, Taylor has dominated the international science fair, walking away with nine awards (including first place overall), overseas trips and more than $100,000 in prizes. After the Department of Homeland Security learned of Taylor’s design, he traveled to Washington for a meeting with the DHS’s Domestic Nuclear Detection Office, which invited Taylor to submit a grant proposal to develop the detector. Taylor also met with then–Under Secretary of Energy Kristina Johnson, who says the encounter left her “stunned.â€
“I would say someone like him comes along maybe once in a generation,†Johnson says. “He’s not just smart; he’s cool and articulate. I think he may be the most amazing kid I’ve ever met.â€
