Technology Engineering Thomas Edison's failed rechargeable battery may get a second life The famed inventor's nickel-iron idea isn't suited for EVs, but it could help solar farms and data centers. Breakthroughs, discoveries, and DIY tips sent six days a week. A rechargeable battery based on technology pioneered by Thomas Edison may finally get its due. But while the famous inventor envisioned nickel-iron batteries powering the automobile industry over a century ago, researchers now believe the underlying concepts are more suited for renewable energy centers. According to a study published in the journal, a team including engineers from the University of California, Los Angeles have developed a prototype battery that recharges in seconds and withstands over 12,000 cycles of use--an equivalent to over 30 years of daily activity.

A cordless, portable blender was barely possible a few years ago. But two cordless blenders are ahead of the pack. But battery tech keeps getting better. This means the best portable blender I've tested, the Ninja Blast Max ($100), is now fully able to make a six-pack of crushed-ice margaritas at your next picnic or blend up a berry-filled protein shake at the gym without breaking much of a sweat. Meanwhile, the ingeniously designed Nutribullet Flip ($115) offers more torque than previous-generation blenders, plus enough insulation to keep ice frozen until it's time for lunch (or even dinner).

Chinese firms are building battery plants from Europe to North America, promising jobs while prompting local concerns about the environment, politics, and who really benefits. When the rest of WIRED subscribers get their hands on our next print magazine, you, dear readers of Made in China, can proudly say you heard about it here first. The issue is all about China and includes stories about robots, AI boyfriends, a Chinese town that became the crystal capital of the world, and a Chinese DNA database built for family reunions. Like this newsletter, the issue is our attempt to document how deeply Chinese technology now shapes everyday life--no matter where you live in the world. As part of the issue, I reported a story on how Chinese lithium battery companies like CATL, BYD, and Gotion are now building factories on nearly every continent.

Plus: Trump has climbed down from his plan for the US to take Greenland. Yann LeCun's new venture is a contrarian bet against large language models Yann LeCun is a Turing Award recipient and a top AI researcher, but he has long been a contrarian figure in the tech world. He believes that the industry's current obsession with large language models is wrong-headed and will ultimately fail to solve many pressing problems. Instead, he thinks we should be betting on world models--a different type of AI that accurately reflects the dynamics of the real world. Perhaps it's no surprise, then, that he recently left Meta, where he had served as chief scientist for FAIR (Fundamental AI Research), the company's influential research lab that he founded. LeCun sat down with MIT Technology Review in an exclusive online interview from his Paris apartment to discuss his new venture, life after Meta, the future of artificial intelligence, and why he thinks the industry is chasing the wrong ideas.

You'd never guess this lock is smart by looking at it, and that's my favorite part. No bulk or screen; looks like a regular lock from both sides of the door. Impressive design with the battery hidden inside the lock bolt. App is beautiful and easy to use. Best with accessories that need to be purchased separately.

When you purchase through links in our articles, we may earn a small commission. Most floodlight cams need hardwired power, limiting your installation options. This battery-powered model can go anywhere, and it has a solar panel, too! Single floodlight isn't as bright as you get with hardwired models Despite a couple of minor bugs, this low-cost, battery-powered floodlight camera knocks it out of the park in most respects. The "Kit" in TP-Link Tapo C615F Kit refers to the inclusion of a solar panel that comes with this full-featured security camera/floodlight combo to keep its battery charged.

China's lithium batteries aren't always "made in China." Companies like BYD and CATL are building factories on nearly every continent. THE symbolism was clear last June when Emmanuel Macron, surrounded by factory workers, held up a sleek lithium battery in his right hand and a mining lamp in his left. He was in Douai, a northern French city with a coal mining history dating back to the 1700s. The city is now also the site of a battery factory, which would allow France to produce all parts of electric vehicles domestically. This factory, Macron declared, represented an "economic and ecological revolution."

At a crucial moment for climate change, these technologies show us where we're heading. I know it's a bit late to say, but it never quite feels like the year has started until the new edition of our 10 Breakthrough Technologies list comes out. For 25 years, has put together this package, which highlights the technologies that we think are going to matter in the future. This year's version has some stars, including gene resurrection (remember all the dire wolf hype last year?) And of course, the world of climate and energy is represented with sodium-ion batteries, next-generation nuclear, and hyperscale AI data centers . Let's take a look at what ended up on the list, and what it says about this moment for climate tech.

Plus: This company is developing gene therapies for muscle growth, erectile dysfunction, and "radical longevity" For decades, lithium-ion batteries have powered our phones, laptops, and electric vehicles. But lithium's limited supply and volatile price have led the industry to seek more resilient alternatives. They work much like lithium-ion ones: they store and release energy by shuttling ions between two electrodes. But unlike lithium, a somewhat rare element that is currently mined in only a handful of countries, sodium is cheap and found everywhere. Read why it's poised to become more important to our energy future. Sodium-ion batteries are one of 10 Breakthrough Technologies this year.
