"The National Ignition Facility uses infrared and ultraviolet laser light to produce X-rays in a chamber with a peppercorn-sized fusion fuel pellet."

"Ma’s office is a giant box of lasers the size of three football fields in the corner of a 7,000-acre lab in Livermore. Running across the soaring white ceilings are miles of square tubes holding 192 of the most energetic lasers in the world, all snaking toward a round room at the center."
"“Every time we do a shot, we are the hottest place in the solar system,” Ma said as she pointed at the miles of mirrors which can amplify $14 worth of electricity into a force “a thousand times the power of the entire US electrical grid. But your lights don’t flicker at home when we take a shot because we’re taking a huge amount of energy and compressing it down into nanoseconds.”
The facility was all built with 20-year-old technology and Ma said that if they were to rebuild it today — or build a legitimate nuclear-fusion power plant — “you would use new technology that is a lot more efficient, could shoot at much higher rates, with higher efficiency and very high precision.”"

"Kim Budil: So if you can get it hot enough, dense enough, fast enough, and hold it together long enough, the fusion reactions start to self-sustain. And that's really what happened here on December 5th."
"The beams strike with a power 1,000 times greater than the entire national power grid. Your lights don't go out at home when they take a shot because capacitors store the electricity. In the tubes, the laser beams amplify by racing back and forth and the flash is a fraction of a second.
Tammy Ma: We have to get to these incredible conditions; hotter, denser than the center of the sun and so we need all of that laser energy to get to these very high energy densities.
All that wallop vaporizes a target nearly too small to see."

"a “Plasma Compression Fusion Device” in 2019, it was either a giant breakthrough – or mad science. According to the patent application, the miniature device could contain and sustain fusion reactions capable of generating power in the gigawatt (1 billion watts) to terawatt (1 trillion watts) range or more. A large coal plant or mid-size nuclear powered reactor by comparison produces energy in the 1–2 gigawatt range. The revolutionary invention by Dr. Pais, if real, would produce near unlimited clean energy from something no larger than a sports utility vehicle."
