How Subways Are Powering Cities. Go to https://ground.news/undecided for an innovative way to stay fully informed on tech, energy, the climate and more. Save 40% on the Ground News unlimited access Vantage plan with my link. Every time a subway screeches to a stop, commuters pour out, new riders pile in. Just another day on the rails. But what if that screech could do more than just move people? In Barcelona, it does. They’ve taken the regenerative braking you might know from your EV and cranked it up to city scale. Now, their metro isn’t just moving passengers, it’s powering escalators, traffic lights … and even EVs. It’s a sneak peek into a future where energy isn’t only harvested from solar panels or massive power plants, but reclaimed from the overlooked rhythm of urban life. So, how much energy are we letting slip through the cracks, and what happens when we start catching it?

Why Nothing Is Truly Waste Anymore. To get your very own Segway Navimow X350 go to https://bit.ly/3GZnOCn. When we talk about the circular economy, we picture batteries stripped for their metals, factory floor scraps spun into sweaters, and agricultural waste transformed into biogas. We don’t picture mucking out the barn to collect material for surgical masks and food packaging. Waste may be used in new household products. It’s now possible to spin it into high-tech, biodegradable plastics and textiles or use it as glue inside lithium battery electrodes. And as for the urine we send down the drain, it might someday help build our cities with better concrete. So, is this the next leap in sustainable design — or just a steaming pile of hype? And how close are we to building a cleaner, greener future from human and animal waste?

Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided Imagine a world where the homes we live in, the clothes we wear, and even the sensors in our electronics weren’t manufactured, but grown. Mycelium, the root structure of fungi, is shaking up everything from sustainable construction to meatless bacon. It’s turning agricultural waste into walls, hemp into compostable packaging, and fungal threads into leather that even luxury brands are eyeing. This mushroom material is set to insulate the façade of a 300-unit housing project in California. And now, innovators are swapping out the sensors of robots for the electrical pulses of living mycelium. So, how long until mycelium is just as ubiquitous as wood, metal, and plastic?

Solar panels are built to last around 30 years, but what if solar panels could last… forever? That’s the promise behind a new kind of perovskite PV cell that can heal itself. Not only does this self-repair help the panel bounce back from damage, but it also helps maintain peak efficiency over time. Breakthroughs like this could reshape the solar industry … as long as they can break out of the lab. So, how do self-healing PVs work? And how close are we to seeing them out in the wild?

Thorium reactors are like the solid-state batteries of nuclear power: vastly superior, yet forever on the horizon. But now, a Danish company is closer than ever to turning them into a reality. These aren’t just thorium reactors — they’re small modular reactors, designed to function as shipping container-sized, self-maintaining batteries that operate reliably for years. So, how is this company tackling such an ambitious engineering challenge? When might commercial thorium reactors finally arrive? And is thorium the missing piece in the clean energy puzzle?

How Living Computers Could Change Everything. Go to https://brilliant.org/Undecided/ and get 20% off your subscription and a 30 day free trial with Brilliant.org! It’s no secret that tech companies are racing to build “artificial general intelligence,” or AI that can match a human brain without needing a lifeline. But our brains already do the same heavy lifting with just a fraction of the resources. Whether it’s energy, water, land, components, or, you know… money… human brains are just way cheaper. Right now, you can either buy a human brain cell-based computer... or rent time on a remote one. Yep, even brainpower’s got a subscription plan these days. So what can these living computers actually do? How do they work? And, most importantly, should we be freaking out a little bit?

Why AI’s Progress Might Destroy Its Own Future. Go to https://surfshark.com/undecided or use code UNDECIDED at checkout to get 4 extra months of Surfshark VPN! You’ve seen the headlines. The viral demos. AI writing essays, generating photorealistic images, even creating entire videos. But something much more important is happening behind the scenes. AI is solving problems we thought were decades away, curing diseases and inventing new materials. But there’s a paradox. Because this same AI revolution that’s supposedly going to create incredible wealth for companies, might be laying the groundwork for an economic collapse that threatens the very progress it's helping to create.

A handful of companies are betting that crushing deep sea pressures can replace the energy-hungry pumps and toxic chemicals that are an inconvenient truth of desalination. By going the extra quarter-mile into the ocean, they’re pioneering a way to turn saltwater into freshwater — slashing costs, curbing pollution, and reducing environmental harm in the process. How on earth…or, under earth…does this work? And could it solve our global water crisis?
