How Subways Are Powering Cities

Every time a subway screeches to a stop, we usually chalk it up to another moment in the daily grind … if we even notice it. Commuters pour out, new riders pile in. Just another day on the rails. But what if that screech, that everyday chaos, could do more than

Why Thorium is About to Change the World

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

Why Ice Might Be the Future of Heating

Heat from ice? It sounds like a joke—or maybe a paradox. But what if the future of warm, cozy homes lies in freezing water? As outlandish as it seems, an English research team is working on a heat pump that runs off actual ice … well, more like slushies. It’

How Record Breaking Perovskites Are Here NOW

Believe it or not, the long-promised next generation of solar panels are here. A tandem perovskite solar panel with higher efficiency than silicon alone has just arrived on the market. The first batch has already been purchased by an undisclosed U.S. customer, which will soon install them in a

How This TRULY Omni-Directional Wind Turbine is Genius

Small wind turbines, or SWTs, have struggled to get off the ground. Not only is siting more difficult for SWTs, but their low efficiencies rarely justify their high costs. They also have to contend with the same kinds of considerations that your typical turbine does, like noise, vibration, environmental impacts,

How This Mechanical Battery is Making a Comeback

This is the Dinglun Flywheel Energy Storage Power Station. At 30 MW, this is likely the biggest Flywheel Energy Storage System on the planet. Don’t let that spin you around though. While its sheer size is unrivaled, It’s not alone. More and more people are turning to mechanical

Can Solar Rooftops Power the World?

Growing the world’s renewable energy capacity has always been a delicate balancing act, and one of the many plates we have to spin during that act is land use. Utility-scale solar and wind parks are rapidly expanding in size and prevalence all over the world, including right near my

How This New Heat Pump is Genius

Where I live in New England in the winter it can get as low as -13 F (-25 C). During summer heatwaves, it can reach over 100 F (40 C). Many of our houses and homes weren’t built for that, and in the United States, we aren’t exactly
