Plastic bottles could power your devices one day

NEWYou can now listen to Fox News articles!

Each year, billions of single-use plastic bottles end up in landfills or oceans. That waste problem keeps growing. Now, a new scientific breakthrough suggests those same bottles could help power your daily life.

Researchers have developed a way to transform discarded plastic water bottles into high-performance energy storage devices called supercapacitors. The work focuses on PET plastic, short for polyethylene terephthalate, which is used in most beverage bottles. 

The research was published in Energy & Fuels and highlighted by the American Chemical Society. Scientists say the discovery could reduce plastic pollution while helping drive cleaner energy technology.

Why PET plastic waste is such a growing problem

PET plastic is everywhere. According to the researchers, more than 500 billion single-use PET plastic bottles are produced every year. Most are used once and thrown away. Lead researcher Dr. Yun Hang Hu says that scale creates a major environmental challenge.

Instead of letting that plastic pile up, the team focused on upcycling it into something valuable. Their idea was simple but powerful. Turn waste into materials that support renewable energy systems and reduce production costs at the same time.

How plastic bottles can store and release energy

Imagine a device that can charge fast and deliver power instantly. That is exactly what supercapacitors do. They store and release energy much faster than traditional batteries, which makes them useful for electric vehicles, solar power systems and everyday electronics. 

Hu’s team found a way to build these energy storage components using discarded PET plastic water bottles. By reshaping the plastic at extremely high temperatures, the researchers turned waste into materials that can generate electricity efficiently and repeatedly.

Here is how the process works:

For the electrodes, researchers cut PET bottles into tiny, grain-sized pieces. They mixed the plastic with calcium hydroxide and heated it to nearly 1,300 degrees Fahrenheit in a vacuum. That heat transformed the plastic into a porous, electrically conductive carbon powder.

The powder was then formed into thin electrode layers. For the separator, small pieces of PET were flattened and carefully perforated with hot needles. This pattern allowed electric current to pass efficiently while maintaining safety and durability. Once assembled, the device used two carbon electrodes separated by the PET film and submerged in a potassium hydroxide electrolyte.

Why the results surprised scientists

When tested, the all-waste-plastic supercapacitor outperformed similar devices made with traditional glass fiber separators. After repeated charging and discharging, it retained 79 percent of its energy capacity. A comparable glass fiber device retained 78 percent. That difference matters. The PET-based design costs less to produce, remains fully recyclable, and supports circular energy storage technologies where waste materials are reused instead of discarded.

What this means for you

This breakthrough could affect everyday life sooner than you might expect. Cheaper supercapacitors can lower the cost of electric vehicles, solar systems and portable electronics. Faster charging and longer device lifespans could follow. It also shows that sustainability does not require giving something up. Waste plastics could become part of the solution instead of the problem. Although this technology is still in development, the research team believes PET-based supercapacitors could reach commercial markets within 5 to 10 years. In the meantime, choosing reusable bottles and plastic-free alternatives still helps reduce waste today.

Kurt’s key takeaways

Turning trash into energy storage is more than a clever idea. It shows how science can tackle two global challenges at once. Plastic pollution continues to grow. Energy demand does too. This research proves that those problems do not have to be solved separately. By rethinking waste as a resource, scientists are building a cleaner and more efficient future from materials we already throw away.

Nvidia, Microsoft, and Arm are all teasing Nvidia’s new N1X laptop processors

It’s the world’s worst kept secret that Nvidia is about to announce its own Arm-powered laptop chips at Computex this weekend, and now Microsoft, Nvidia, and Arm are all openly teasing the announcement. The Windows and Nvidia GeForce accounts on X both posted “A new era of PC” earlier today, and now Arm has followed up with an identical post.

All three posts include coordinates pointing to where Computex is hosted in Taipei. Nvidia is holding a Computex keynote in Taipei at 8PM PT / 11PM ET on Sunday night, where it’s rumored to be announcing its new N1 and N1x laptop chips.

These Arm-powered Nvidia processors have been long-rumored, with reports earlier this year suggesting that both Lenovo and Dell have been preparing new laptops with the N1X chips. We first heard rumors about Nvidia’s laptop processors in 2023, and Dell CEO Michael Dell hinted at the possibility of an AI PC with Nvidia during an interview in 2024.

Nvidia’s entry into Windows on Arm will mean Qualcomm will no longer have an exclusive license for Microsoft’s Windows 11 Arm variant of its operating system. That’s good news for laptop competition, even if Qualcomm is trying to keep entry-level laptops affordable with its new Snapdragon C platform.

Hyundai to send 25,000 Atlas robots to the US

NEWYou can now listen to Fox News articles!

Hyundai wants to bring humanoid robots into American car factories in a big way. The company is looking at a future where Boston Dynamics’ Atlas robots work alongside people inside U.S. auto plants. 

These human-shaped machines can bend, lift, balance and move through spaces built for workers. That could change how cars get made. It could also raise new questions about factory jobs, safety and how much automation consumers are willing to accept.

Here’s what Hyundai is planning and why Atlas could become one of the most closely watched robots in American manufacturing.

BMW PUTS HUMANOID ROBOTS TO WORK BUILDING EVS

Hyundai Atlas robots are headed to U.S. factories

Hyundai Motor Group reportedly outlined plans to deploy more than 25,000 Atlas robots developed by Boston Dynamics across Hyundai Motor and Kia manufacturing facilities. The plan appeared in investor relations materials tied to a JPMorgan Chase-hosted session.

The company also plans to build annual production capacity for 30,000 Atlas robots by 2028. Hyundai has not released a detailed public schedule for every plant. However, Kia CEO Song Ho-sung said the robots are expected to begin work in 2028 at Hyundai Motor Group Metaplant America in Georgia. Kia’s Georgia plant would follow in 2029.

Why Hyundai wants Atlas humanoid robots

Hyundai faces the same pressures as other automakers. It needs faster production, flexible factories and better ways to handle labor shortages. Humanoid robots may help because they can work in areas designed for people. That can reduce the need to rebuild a factory from scratch.

Atlas could also help with physically demanding jobs. Lifting, carrying and moving awkward objects can wear down workers over time. If robots take on some of that work, factories could become safer. Still, this technology will need careful oversight. A humanoid robot working near people must move predictably and stop safely when something goes wrong.

How Boston Dynamics trained Atlas to lift

Boston Dynamics recently showed Atlas handling a heavy object in a new technical demo. The robot squatted down, picked up a mini-fridge, rotated its torso and carried the object while keeping its balance. The company says Atlas learned this behavior through reinforcement learning and simulation training. In simple terms, the robot practiced in a computer world before testing the skill in real life.

Engineers changed the object’s weight, floor friction, grip force and placement during training. That helped Atlas learn how to adapt when conditions changed. That is important because factory work rarely happens in perfect conditions. Parts shift. Floors vary. Workers move around. Loads can feel different from one moment to the next. Atlas needs to react in real time, not freeze when a task changes. 

What makes Atlas different from older robots

Many robots rely heavily on cameras. Atlas also uses proprioception, which means internal body awareness. That may sound technical, but the idea is easy to understand. When you carry a grocery bag and the weight shifts, you feel it. Your body adjusts before you think about it.

Atlas uses sensors and software to do something similar. It monitors balance, grip pressure, resistance and body movement as it works. Boston Dynamics says the new Atlas platform also helps reduce the gap between simulation and real-world movement. The robot uses a simplified hardware design, symmetrical limbs and only two actuator types.

Actuators are the robot’s joints and muscles. Hyundai reportedly plans to make more than 300,000 actuator units each year at U.S. facilities. That shows Hyundai wants control over the parts that make humanoid robots move.

Hyundai Atlas robots raise job questions

The biggest concern is obvious. What happens to workers when thousands of humanoid robots enter factories? Companies often say robots will take on dull, dirty or dangerous tasks. That may be true in many cases. However, workers will still want clear answers about training, staffing and job security.

The rollout could create new roles in robotics maintenance, safety monitoring and factory software. It could also reduce the need for some physically demanding jobs over time. That trade-off will follow Hyundai’s robot plan closely. The company will need to show that Atlas improves factory safety and productivity without pushing workers aside without support. For now, Hyundai has not provided enough public detail to answer those workforce questions fully.

What this means to you

This story may sound like it only affects autoworkers or car companies. But it could eventually touch anyone who buys a car. If humanoid robots help factories move faster, automakers may adjust production more quickly when demand changes. That could affect wait times for popular models.

Robot-assisted manufacturing could also influence vehicle costs. Automation can lower some production expenses, although savings do not always reach buyers right away. The bigger shift may be trust. Consumers may soon ask how much of their vehicle was built by humans and how much was handled by robots. That does not automatically make the car better or worse. But it does change the story behind how that car reached your driveway.

Kurt’s key takeaways

Hyundai’s plan to deploy more than 25,000 Atlas humanoid robots in the U.S. marks a major shift for auto manufacturing. This is one of the clearest signs yet that humanoid robots are moving from demos into real industrial work. The Georgia rollout will be especially important. If Atlas performs well at Hyundai and Kia facilities, other automakers may feel pressure to speed up their own robotics plans. Still, the hard part starts on the factory floor. Atlas must work safely around people, handle unpredictable tasks and prove it can do more than impress in videos. The technology is exciting. The job questions are real. Hyundai now has to prove that both can be managed responsibly.

Acer’s launching a Linux handheld for streaming your PC games

Acer’s launching a Linux handheld for streaming your PC games

The Acer Nitro Blaze Link might run on Linux, but it’s no Steam Deck. Acer says it’s a “streaming-first handheld and companion device,” like a PlayStation Portal for your PC. Announced ahead of Computex on Friday, it’s launching in Q4 2026 with a 7-inch (1920 x 1200) display, Wi-Fi 6, just 1GB of LPDDR4 RAM, and 8GB of eMMC storage. That’s technically not even enough RAM to run Stardew Valley, but the Blaze Link isn’t meant for playing games locally.

Logitech launched a similar handheld a few years ago, the Logitech G Cloud, that cost $350, included 4GB of RAM and 64GB of storage, and ran on Android. It was a tough sell at that price considering that its performance was dependent on a good internet connection.

Acer hasn’t yet announced a price for the Nitro Blaze Link. But its specs suggest it could cost significantly less than proper handheld gaming PCs — which have been skyrocketing in price — potentially offering a more affordable and streaming-first alternative.

Correction, May 29th: The Nitro Blaze Link was announced ahead of Computex 2026, not at it.
