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.

Are robots coming to a McDonald’s near you?
NEWYou can now listen to Fox News articles!
Walk into a McDonald’s, and you expect a familiar routine. You order, wait and grab your food. At one location in Shanghai, that routine briefly looked very different.
McDonald’s deployed robots from Chinese robotics firm Keenon Robotics in one of its fast-food restaurants as part of a short-term test tied to a store opening. The robots greeted customers, added a bit of entertainment and helped with simple service tasks.

What actually happened at this McDonald’s in Shanghai
This test happened at just one location. It was not a rollout. It was a short pilot tied to a store opening. Inside the restaurant, humanoid robots greeted customers and added a fun, interactive element. You can see them wearing McDonald’s uniforms and making simple gestures for diners. At the same time, other robots handled basic tasks like delivering food and clearing trays. It was a mix of different machines working together, not a fully integrated system.
Human workers still did the real work behind the counter. They handled cooking, orders and anything that required judgment.
In the end, this looked more like a live demo than a real shift in operations. The robots were there to attract attention, not replace staff.
Why McDonald’s is experimenting with robots
Even though this was a small test, it reflects a much bigger trend. Restaurants in many regions are dealing with hiring challenges. At the same time, fewer workers are interested in repetitive, lower-paid roles. That creates an opportunity for automation. Robots can handle simple, repetitive tasks with consistency. They do not get tired, and they can operate for long hours. For fast-food chains, that level of reliability is appealing. At this stage, the technology is not advanced enough to replace human workers. But it can support them in limited ways.
Are robot workers the future of fast food?
Not yet. This test was more about exploring possibilities than changing operations. The robots acted more like a demonstration of what could come next rather than a working solution ready for scale. Right now, the most realistic future is a hybrid model. Humans continue to handle cooking, customer issues and complex tasks. Robots assist with basic service and customer-facing roles. That balance could evolve over time as the technology improves.
Why robot tests matter for the future of fast food
Even short-term experiments can signal where things are headed. Robots can speed up service, reduce long-term labor costs and create a unique experience that attracts customers. For families and younger diners, interacting with a robot can turn a routine visit into something memorable. That novelty factor alone makes these tests valuable for companies looking to stand out.

Why fast food automation is still in the early stages
Today’s robots are limited. They struggle with complex tasks and unpredictable situations that require human judgment. Cooking, handling special requests and managing busy environments still depend on people. That is why this test remained small and temporary. It shows potential, but it also highlights how far the technology still has to go.
What this means to you
You are not about to walk into a fully automated McDonald’s. But you may start seeing more technology in everyday places. That could mean faster service and fewer delays. It could also mean less direct interaction with human staff. Jobs in fast food are unlikely to disappear overnight. Instead, they may shift toward roles that focus on customer support, problem-solving and managing technology. At the same time, these early tests raise questions about how far automation will go and how quickly it could change the workforce.

Kurt’s key takeaways
This was not a rollout. It was a glimpse. McDonald’s used humanoid robots in one location for a short period to test reactions and explore possibilities. The machines added novelty, but they did not replace workers. Still, the direction is clear. Automation is moving into everyday spaces, one small test at a time.

Red Rooms makes online poker as thrilling as its serial killer
It’s rare for a movie to get technology right. And it’s even rarer for that movie to be a thriller or horror, where realism takes a backseat to scares and tension. But Red Rooms mostly gets it. Nothing takes me out of a film quicker than a tech MacGuffin that might as well be literal magic. Yes, the phrase “dark web” will always sound a bit silly, but at no point during its 118 minutes does the tech become a distraction.
It’s not the tech that makes Red Rooms great, though. It’s just something that could have easily tanked an otherwise excellent movie. What carries the film is the expert tension building by director Pascal Plante. The perfect slow-burn pacing. And the incredible performances by Juliette Gariépy as Kelly-Anne and Laurie Babin as Clementine.
The film centers mostly on Kelly-Anne, a model / hacker / professional gambler who attends the trial of serial killer Ludovic Chevalier. She befriends Clementine, a fan of Chevalier who insists that he is being framed.
Clementine neurotically and loudly defends Chevalier, calling into TV shows and shouting at reporters outside the courtroom. She makes a spectacle of herself. But Kelly-Anne remains more mysterious, her motives unclear. Even at the end of the film, there is ambiguity about what she was trying to accomplish and why.
The ambiguity is part of what makes Red Rooms so enthralling. The movie feels unpredictable. None of the characters seem trustworthy or relatable. The world they inhabit is familiar, yet uncanny.
The movie lingers in that discomfort for long periods of time, making you squirm. Giving you the opportunity to play through all the possible scenarios that could play out in your head. Is Chevalier really the killer? Is Kelly-Anne the killer? Was one of the victim’s mothers an accomplice? Is the prosecutor keeping a secret?
The movie inches along, drawing out a tale of kidnapping, live-streamed torture, and snuff films before erupting into a climax that unexpectedly mines online poker and Bitcoin for legitimate drama. It’s ultimately less about the murders themselves than it is about obsession, internet bubbles, and the media. It almost feels like a grimier companion piece to David Fincher’s Gone Girl.
