Inside the National Ignition Facility. Lawrence Livermore National Lab is building the world’s largest laser. Actually, the National Ignition Facility won’t have only one laser beam. It will use 192 world-class lasers, all firing simultaneously. In a few billionths of a second about 500 trillion watts, which is nearly 1000 times the power generated in the entire US at any moment, will hit a target the size of a dime. The hope is that this will create enough heat and pressure to mimic the core of the sun and achieve a fusion ignition.

So in a nutshell, what is fusion? And how do lasers work? Why are you asking me? I was the kid who always struggled with math and would get hives on the eve of a high school science test.

Luckily, there are some darn good teachers out there and we were fortunate enough to feature one of them in our story. Richard Muller is a professor of physics at the University of California and has also become something of a web phenomenon. Thousands of “students” all over the world have viewed his lecture series titled “Physics for Future Presidents” on YouTube and Cal’s own website.

Muller designed this class to “stress conceptual understanding rather than math, with applications to current events.” As he told us, “imagine looking out on your classroom and picturing out there is the future president of the United States. What do you want that person to know?” What comes out is an explanation of the physics of energy, nuclear weapons, radioactivity, relativity and the universe– all explained in a way that the physics-challenged, like myself or maybe a future president, can understand.

Scientist Alex Gash prepares the “frozen smoke.”
I’ve always loved cooking shows. There’s something so satisfying about watching an expert gather, wash, peel, macerate, combine and assemble ingredients. And because of the magic of television, we get the whole enchilada neatly packaged within a half hour program. Everything’s perfectly cooked, presented and served. And I don’t have to do the dishes.

So when I conceived this Aerogel segment, I had a cooking show in mind. I imagined the mad scientist, standing at his bench in requisite white lab coat and safety glasses, Bunsen burner bubbling away. And the big reveal at the end, pulling a perfectly-formed cylinder of Aerogel from the supercritical extractor. Well, it turns out that the process of making Aerogel isn’t terribly visual. Essentially, there’s a lot of clear liquid being added to clear liquid. Which becomes clear gel. Then it’s put into a machine and it comes out Aerogel.

So, it’s a good thing that our chemist, Alex Gash, was a rock star. He was such a good sport, saying the same thing over and over in just slightly different ways without a single complaint. And even though he works with Aerogel (Sol Gel chemistry) every day, it still seemed like he was pretty excited about it.

So, while it’s not exactly a cooking show, we hope that our little segment piques your interest to find out more about how Aerogel is made as well as its really interesting applications. Maybe you can even print out the recipe and make it at home.

It’s one of the most expensive high-tech projects the United States has ever attempted, and some say it will never work. QUEST visits the National Ignition Facility in Livermore, where scientists will soon aim the world’s largest laser at a target the size of a pencil eraser. The goal? Nuclear fusion — and, they say, the answer to the world’s clean energy needs.
