This Battery Has Blood In It (Kinda). What if the secret to next-generation batteries is circulating in your blood, and the blueprint for powering AR contact lenses is swimming in the Amazon? Humans have been building batteries for a couple hundred years, but nature has been perfecting energy systems for
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. Engineers are constantly looking for ways to
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
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. Its reactors are designed to deliver on thorium’s decades-old promise: a self-sustaining chain reaction that breeds fresh
Freshwater may soon flow from the depths of the ocean to drought-stricken coastal cities. A handful of companies are betting that crushing deep-sea pressures can replace the energy-hungry pumps and toxic chemicals that are desalination’s inconvenient truth. By going the extra quarter-mile into the ocean, they’re pioneering a
Every crashing wave delivers a pulse of power. Add them all up, and the ocean carries more energy than the roughly 30,000 TWh of electricity generated globally in 2023.12 But for decades, wave power has been a sea of broken dreams — sunk prototypes, busted budgets, and forgotten startups.
You’ve heard of paper straws and cups, but how about a paper battery? One you can compost when you’re done with it. Two companies are already proving it works, one of them with a battery that runs on sugar. So how did humble paper become a next-generation battery
CORRECTION: the original version stated that silver "price has tripled in the past three years." It's demand that tripled, not price. As renewable energy installations multiply across the globe, the first generation of solar panels, wind turbine blades, and lithium batteries is reaching the end of
Solid-state batteries could address some of the biggest issues facing energy storage and EVs; safety, charge capacity, and longevity. But the biggest problem they face? Cost. You can probably see why my interest was piqued when I heard about a new electrode manufacturing technique that apparently uses less energy, less
As the new wave of generative AI scales up, so does its hunger for energy. Data centers are expanding at an unprecedented rate, putting immense strain on power grids and worsening years-long backlogs for electrical connections. With AI adoption accelerating across industries, big tech companies are tapping nuclear power as
Industries have long been criticized for their environmental impact, but some companies are starting to break away from the pack and set new standards for sustainability and innovation. These companies aren’t just cutting back on emissions and waste, but reinventing the entire life cycle of their products. And who
