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?

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?
