Researchers at the National Ignition Facility (NIF) have reported that their nuclear fusion reactor has managed to achieve repeated "ignition" (net zero or net energy gain) repeatedly over the last year. First achieved about a year ago in December 2022, the NIF has repeated the trick multiple times in 2023. Located at the Lawrence Livermore National Laboratory (LLNL) in California, this is a fantastic achievement and very promising for the future of clean, near-inexhaustible energy.

“I’m feeling pretty good,” Richard Town, a physicist who heads the lab’s inertial-confinement fusion science program at the LLNL, told Nature. “I think we should all be proud of the achievement," he added.
