Do you remember what your greatest accomplishment was at age 13? Well, it doesn’t really matter either way, because whatever it was, Jamie Edwards—the tween scientist who’s now the youngest person to ever carry out atomic fusion—just crushed it.

He chain smokes. He loves his guns. And he almost looks homeless. But he’s actually pretty damn awesome. Meet Doug Coulter. A gunsmith who’s also an amazing DIY engineer. So amazing that he’s built a nuclear fusion reactor in his basement. Yup.

Nuclear fusion, the same process that powers the sun, could provide us with limitless cheap energy—but experiments to date have always used more power than they created. Now, though, researchers have apparently tipped that balance, making fusion a real possibility.

Sandia National Laboratories’ Z machine sounds like it belongs in a James Bond movie more than it does an Alberquerque research facility. Based on what it can do, that’s not as far-fetched as it seems. What you see isn’t the handiwork of some electric spider — it’s what you witness in the immediate fraction of a second after the Z’s electromagnetic pulse kicks in and forks of lightning burst across the 108-foot distance inside. The pulse in question is key to Sandia’s studies of fusion and the effect of very intense magnetic pressures on materials that normally refuse to change states. Even in 2006, the Z was putting out pressure more than 10 million times that of the atmosphere, and it successfully melted diamond at roughly half that strength. It goes without saying that we don’t want to be anywhere near this kind of energy when scientists flick the switch, but we’re glad to see that something so pretty and deadly can help us understand physics.

In an effort to recreate the fusion reaction that occurs in start formation, the National Ignition Facility in Livermore, CA has been building up to some extremely powerful laser shots. Back in March, researchers fired off 411 terawatts, and we know that kind of power doesn’t come cheap. NIF’s latest test shot, fired July 5th, set a new record with 192 lasers producing more than 500 trillion watts of peak power and 1.85 MJ of ultraviolet laser light. Mind you, that’s more than a thousand times more energy than the United States uses at any given moment, not to mention a hundred times more power than other lasers can fire consistently. More record-setting shots are sure to come, and in addition to enabling research on harnessing nuclear fusion, NIF’s mega-lasers are helping inform the design of new laser facilities being built in China, Japan, Russia, France and the UK.
