You’ve probably heard about nuclear fusion. Maybe you've heard recent news about the Livermore National Lab achieving a nuclear fusion breakthrough called "ignition" - meaning it produced more energy than it took to start the reaction. That's a huge deal! But it leaves other questions unanswered. I wanted to know more.

I started by asking the CEO of the nuclear fusion company Helion all my big questions: What is nuclear fusion, really? I know it happens on the sun, but how can we do it on earth? Are we doing it already? Then, I ask one last question: “I’ve heard about kids building fusion reactors in their moms’ garage… if fusion is so hard… what are THEY doing?” The answer sets off the most fun and ambitious Huge If True episode yet.

It turns out that you can actually BUILD a nuclear fusion device. So I team up with my friend Simone Giertz to try. When something goes wrong, it turns into an explainer on what’s really going on with the world’s most-hyped energy source.

Special thanks to Jessie, Ron and Joben at Helion for helping set up such an exciting shoot (and not giving up!). And thank you to Anna Bresnahan for helping shoot this episode!

Welcome to the joke down low:

How does a nuclear physicist ask for a salary increase?
Gamma rays.

Find a way to use the word “rays” in a comment to let me know you’re a real one ;)
