How IKEA-Style Wind Turbines Could Change Offshore Energy

You know what an offshore wind turbine looks like. A giant pole, three blades, bolted to the seafloor. The catch is it only works in shallow water, around 80 meters or less. That rules out most of the ocean, which is where the strongest, steadiest winds actually are. A Swedish company called SeaTwir

The Solar Underdog That Could Rival Perovskite

Perovskite solar cells are smashing efficiency records and starting to hit the market, but what if the real future of solar is a material you’ve probably never heard of? It’s called kesterite, and new research suggests it could match perovskites’ efficiency without any toxic lead in the stack.

How Hydrogel Can Double Solar Panel Lifespan

Why are the world's most efficient solar panels learning to sweat? When it comes to solar, you'd assume more sun equals more power, but the truth is that solar panels actually hate being hot. In fact, for every single degree the temperature rises, these panels lose

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
