This is the best summary I could come up with:
US scientists have achieved net energy gain in a nuclear fusion reaction for the second time since a historic breakthrough in December last year in the quest to find a near-limitless, safe and clean source of energy
Scientists at the California-based Lawrence Livermore National Laboratory repeated the breakthrough in an experiment in the National Ignition Facility (NIF) on 30 July that produced a higher energy yield than in December, a Lawrence Livermore spokesperson said.
The approach, which gives rise to the heat and light of the sun and other stars, has been hailed as having huge potential as a sustainable, low-carbon energy source.
In December, Lawrence Livermore first achieved a net energy gain in a fusion experiment using lasers.
The Energy Department called it “a major scientific breakthrough decades in the making that will pave the way for advancements in national defense and the future of clean power.”
Fusion energy raises the prospect of plentiful clean power: the reactions release no greenhouse gases or radioactive waste byproducts.

Pick a magazine/community and post it ONCE. Thanks.

Due to the way Lemmy is set up and how people subscribe to communities, if you want something to have a wide reach, you need to post it to multiple instances of the same community. Similarly, if you're trying to gauge, as I am, which of the 7 different "tech" subs or "news" subs actually has community engagement, you need to post to all of them. Interestingly, with the news subs, the ones with more comments are not consistent and not always the ones I expected. Also, the type of engagement varies from community to community so it's pretty interesting seeing how different people in different instances react to the same article.
It'll even out over time, but if you don't like it, you can always block me.

Kinda.
The final laser stage of the NIF test was 20MJ and produced 25MJ. But charging the capacitors required over 400MJ.
Sounds like you are just repeating the article without understanding it. They still have to pre charge the capacitors used with the laser, while once charged, they only use so much energy in the process you still have to charge the capacitors and acting like that is not part of the process is extremely disingenuous when charging them takes like 16x the energy generated from fusion before the test can even begin. Ffs
Exactly can we stop acting like it was actually a net positive when we dismissed the energy used to charge the capacitors in this process.
