A Fusion Energy Breakthrough? Watch Live as US Scientists Make Major Announcement

A fusion reactor at Lawrence Livermore National Laboratory may have reached a critical milestone.

Scientists at Lawrence Livermore National Laboratory may have achieved a remarkable new high point for fusion reactions, generating even more energy than was pumped in during a recent experiment, according to a report by the Financial Times.

The publication suggests scientists «with knowledge of preliminary results from a recent experiment» have discussed the result and analysis is ongoing. A major announcement is scheduled to take place at LLNL on Tuesday, Dec. 13. It’s expected to be livestreamed by the Department of Energy at approximately 7 a.m. PT.

The National Ignition Facility operates an «inertial confinement fusion» experiment, which sees almost 200 lasers fired directly at a tiny capsule of hydrogen. According to Nathan Garland, a physicist at Griffith University in Australia, the lasers create a plasma around the capsule which eventually starts an implosion — these conditions allow for fusion reactions to take place.

Fusion is the reaction that powers our sun and it works by smashing two atoms together. This requires extreme pressure and extreme heat but trying to recreate the conditions in a lab is «super difficult,» noted Garland.

The energy released by fusing two atoms together is massive and, importantly, releases no carbon dioxide. Unlike fission — splitting atoms — used in nuclear power plants, fusion also leaves behind no radioactive waste and there’s no risk of meltdown, either. In short, if we could harness fusion power, it would revolutionize energy, allowing us to generate clean power without pumping greenhouse gases into the atmosphere.

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. In a fusion experiment, if Q > 1, then we’re on our way to a bona fide energy breakthrough, one that scientists have long been dreaming of reaching. «It is a big deal for sure, if true,» Garland said.

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.

In more recent times, though, NIF has taken big strides toward achieving the goal. In August 2021, researchers reported they had, for a brief moment, re-created the power of the sun in a self-sustaining reaction. That’s a good pedigree and one that makes us here at CNET Science feel a little more confident in the rumors.

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.»

The result won’t mean that we suddenly have an endless supply of energy. It’s likely the reaction that took place at NIF lasted for just a fraction of a second or even less. But this is the first step in a journey toward fusion energy as a viable, serious technology to power our world. It provides a proof of concept that fusion experiments like this can reach Q > 1.

So while I’m always cautious about throwing around the word «breakthrough» when reporting on cutting-edge science — especially in the realm of fusion energy — it does feel like it might be justified here. We’ll have to wait and see.

Updated Dec. 12: Changed sentence to «smashing two atoms together» rather than «heavy» atoms because hydrogen is, of course, a very light atom.

If You’re Flying for the Holidays, This Bluetooth Dongle Transforms In-Flight Movies, and It’s 35% Off for Black Friday

Watch airplane movies just like you would at home with this game-changing device.

Air travel for the holidays can be stressful, especially when winter weather or flight delays force a change of plans, but one perk of flying still remains — watching new-release movies. However, in-flight entertainment on most airlines usually requires a wired set of earbuds. (And the ones the airline hands out are so bad they may as well not even be connected.)

I’d far prefer to use my wireless, noise-canceling AirPods Pro, but they connect only via Bluetooth. There’s a simple tech solution that makes viewing movies on the plane feel more like watching them on your couch.

The AirFly is a simple Bluetooth dongle that allows me to connect my wireless earbuds directly to the airplane’s entertainment system, eliminating the need for adapters or wired workarounds.

It’s become a must-pack item in my travel bag. Since I started using it, I’ve stopped dreading in-flight audio and finally get to enjoy movies on the plane. If you fly often, this little gadget could completely change how you travel. And the base level AirFly SE is 35% off for Black Friday at Amazon.

The AirFly Pro lets me enjoy in-flight entertainment

The AirFly Pro from Twelve South is a minimally designed dongle that allows me to connect to the 3.5mm headphone jack in my airplane seat, enabling me to listen to in-flight entertainment on my noise-canceling earbuds.

All I have to do is pair the AirFly with the Bluetooth headphones I’m using, such as my AirPods Pro, plug the AirFly into the display in front of me, and I’m all set. I don’t even need to use my phone to connect the two devices.

There are several versions of the AirFly: the AirFly SE, which is currently on sale for $26 on Amazon and connects to just one set of headphones, the AirFly Pro at $55, the Pro V2 at $60 and the Pro 2 Deluxe at $70, which comes with an international headphone adapter and a suede travel case.

Hey, did you know? CNET Deals texts are free, easy and save you money.

I use the AirFly Pro, which has been a game-changer for me on flights. I’ve never had to worry about battery life since the AirFly Pro lasts for over 25 hours and can be fully charged in just three hours. I can also pair two separate pairs of headphones to a single AirFly Pro, in case I’m with someone else on a flight and want to watch the same movie or show.

And if that’s not enough, the AirFly Pro also doubles as an audio transmitter, allowing me to turn any speaker with a headphone jack, such as my old car stereo, into a Bluetooth speaker.

The AirFly Pro makes a great gift for any traveler

The AirFly Pro is the perfect present to give to someone who’s planning to travel this year. Besides my Anker MagSafe battery pack, the AirFly Pro has become my most treasured travel accessory when I fly, which is why I consider it one of those can’t-go-wrong gifts.
