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.

Amazon’s Delivery Drivers Will Soon Wear AI Smart Glasses to Work

The goal is to streamline the delivery process while keeping drivers safe.

Amazon announced on Wednesday that it is developing new AI-powered smart glasses to simplify the delivery experience for its drivers. CNET smart glasses expert Scott Stein mentioned this wearable rollout last month, and now the plan is in its final testing stages.

The goal is to simplify package delivery by reducing the need for drivers to look at their phones, the label on the package they’re delivering and their surroundings to find the correct address.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

A heads-up display will activate as soon as the driver parks, pointing out potential hazards and tasks that must be completed. From there, drivers can locate and scan packages, follow turn-by-turn directions and snap a photograph to prove delivery completion without needing to take out their phone.

The company is testing the glasses in select North American markets.

Watch: See our Instagram post with a video showing the glasses

A representative for Amazon didn’t immediately respond to a request for comment.

To fight battery drain, the glasses pair with a controller attached to the employee’s delivery vest, allowing them to replace depleted batteries and access operational controls. The glasses will support an employee’s eyeglass prescription. An emergency button will be within reach to ensure the driver’s safety.

Amazon is already planning future versions of the glasses, which will feature «real-time defect detection,» notifying the driver if a package was delivered to the incorrect address. They plan to add features to the glasses to detect if pets are in the yard and adjust to low light.
