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.
BEST Things I Saw in Vegas at CES 2026 CES can be a mixed bag. But between the robot invasions…and AI takeovers…I encountered tech that really stopped me in my tracks. First, a solid-state battery claim so bold that even battery skeptics are doing a double take. We’
What if your phone battery charged in seconds instead of hours? What if buildings could cut their carbon emissions in half? What if medical sensors could detect diseases years earlier than they do today? Graphene was supposed to deliver all of this and more. Since 2004, researchers called it a
I called 2024 the year of perovskites. We got our first commercial shipments and some record-breaking efficiencies. But 2025? This was the year perovskites went from “interesting lab tech” to “you can actually buy these.” Oxford PV shipped the first commercial batch to a US solar farm.12 California startups
What if you could power cities just by mixing river water with seawater? Around 15,000 TWh of energy pours into the oceans each year as freshwater blends with saltwater at river mouths. That amounts to roughly half the energy the world consumes in electricity every year.12 And we
What if solar panels could generate twice the power for a fraction of the cost, making them cheap enough that you’d actually want them on your roof? Researchers in Australia may have just pulled it off. This is a solar cell made with both perovskites and graphene, the record-breaking
Electricity bills have been climbing across the US, but the AI boom is making it worse. A lot worse. New data centers are popping up everywhere to handle ChatGPT, Gemini, and countless other AI tools. And here’s the kicker: you’re helping pay for them whether you use AI
What if every piece of plastic waste, like bottles, bags, even clothes, could be rebuilt from scratch, no sorting required? Not just melted and reshaped, but broken down to pure chemical building blocks and made new again. That’s what a new wave of recycling tech promises. At Northwestern University,
If you’ve been following battery tech for the past decade, you’ve heard the solid state battery story before. Toyota promised them by 2025. Samsung said they were just around the corner. QuantumScape’s stock soared on promises of revolutionary batteries. And yet here we are, still driving cars
I’ve had my geothermal heat pump for the past two years now. So far, it’s been helping me to reach my net zero energy goals in my new house (or maybe I should say my “not so new” house now). But getting it installed meant drilling a 400-foot-deep
We’ve been told for years that fast-charging kills batteries. The typical warning is that if you spring for too much current too quickly, you’ll cook the lifespan. But what if that rule is wrong? A team at the Georgia Institute of Technology just flipped the script. They found
This kite isn’t just soaring gracefully … it’s also generating energy from the wind. If you’re like me, you’re probably thinking: “Neat, but don’t we already have an effective and reliable way to capture wind energy?” And yeah, wind turbines have been been big ol’ work
