A lot of hopium hype going out this evening in the mainstream media …

Sorry, here's the real story, folks. I'll bet that they didn’t include the energy loses at both ends of the process of using laser beams to produce fusion in their Q > 1 calculation. Not the loses in turning electricity into a laser beam (there are losses, for instance, in storing electricity in capacitors) and not the loses in turning the heat produced back into electricity so the next cycle of producing laser beams can occur.
Also, as noted in a previous post four months ago, in the experiment where they achieved what they claimed was a Q of 0.7, they admitted that they couldn't reproduce it. It happened in a single shot and successive experiments produced at most 50% as much energy. This was single shot as well. So can it be replicated consistently or do we have to wait 4 to 6 months between successful shots?
And let's not be deceived into thinking LLNL is doing these experiments with fusion power plants in mind. LLNL charter is weapons development. And this is just hype to keep the funding coming. VERY expensive funding, piggy backed on the Climate Change lie as well. And they're so desperate for funding that they hype the program (schedule a big announcement in Washington) even before, they admit, they confirmed the result. That's not the way science should be done.

Well, that piqued my interest. So I went looking for more details …U.S. to announce fusion energy ‘breakthrough’
Scientists hit a key milestone in the quest to create abundant zero-carbon power through nuclear fusion. But they still have a long way to go.
The Department of Energy plans to announce Tuesday that scientists have been able for the first time to produce a fusion reaction that creates a net energy gain — a major milestone in the decades-long, multibillion dollar quest to develop a technology that provides unlimited, cheap, clean power.

https://www.foxbusiness.com/energy/us-s ... rgy-reportThe National Ignition Facility operates an "inertial confinement fusion" experiment which sees almost 200 lasers fired directly at a tiny capsule of hydrogen. … snip ... If the FT report and chatter on social media is correct, scientists at LLNL could have achieved "fusion energy gain" which is denoted by the letter Q. … snip …. But, as with all science, it's good to be cautious and not overhype results yet to be fully analyzed. We have been here before, after all. In 2013, reports swirled the NIF had achieved this exact feat. It wasn't the case. … snip …. A spokesperson for LLNL told CNET "our analysis is still ongoing, so we're unable to provide details or confirmation at this time" and provided a link to the media advisory -- which, in all caps, suggests a "MAJOR SCIENTIFIC BREAKTHROUGH."

U.S. government scientists at a California laboratory have reportedly made a monumental breakthrough in harnessing the power of fusion energy. ... snip ... Though developing fusion power stations at scale is still decades away, the breakthrough has significant implications as the world seeks to ween itself off of fossil fuels. "If this is confirmed, we are witnessing a moment of history," said Dr Arthur Turrell, a plasma physicist, told the paper. "Scientists have struggled to show that fusion can release more energy than is put in since the 1950s, and the researchers at Lawrence Livermore seem to have finally and absolutely smashed this decades-old goal."
Game changer indeed. (Sarcasm)The fusion reaction produced about 2.5 megajoules of energy, around 120 per cent of the amount of energy used in the lasers. ... snip ... "If this fusion energy breakthrough is true, it could be a game changer for the world," tweeted Ted Lieu, a member of Congress from California.
