The LLNL fusion result was not a breakthrough. The fusion output was about 1% of the energy input. The exaggerated press release was just a PR ploy to get support for continued DoE funding, which was expiring at the end of 2022.
And while we talk about fusion, even when the energy output surpass the energy input and the reaction is stable enough, how to you harness the energy? Because the reaction happen within a vacuum, the only way is to capture expelled neutrons and make electricity from it somehow.
