This is Vertical Harvest. Sitting on half an acre of land, it produces as much food as an equivalent 250-acre farm. That’s a 500 times more efficient use of land than traditional farming. But if vertical farming is so great, why isn’t it more popular? And where and
I have some regrets. A few years ago, I set out to build my dream net zero energy home. I've been living here for a little over two years now, and so far, I’ve been more than satisfied. I have enough solar and battery storage to balance
Ever since Donut Lab announced their miracle solid-state battery, the internet has been absolutely certain about what it is. A capacitor. Vaporware. A scam. Except when you actually dig into those explanations, a lot of them start falling apart. Here's what Donut Lab is actually claiming: more energy
Perovskite solar cells could hit 35% efficiency and cost half as much as silicon, but they're still years away from your roof. Meanwhile, silicon panels just lost their 30% federal tax credit in the US, making them suddenly more expensive. So here's the $20,000 question:
What if the most efficient way to heat and cool your home…might not actually be the best choice for you? Geothermal heat pumps are the gold standard for efficiency. They're also the most expensive upfront investment you can make in your home's HVAC system. So,
When Spain's power grid failed on April 28th, 2025, it quickly became a very serious issue. Not only for the economic impacts, but life-or-death serious due to multiple, indirect deaths associated to the blackout. Emergency services, transportation, communication and other vital services were halted during this power outage.
Your lights just flickered. Not for long. Just a split second. You probably didn't think much about it, but somewhere a battery may have just saved your city from a blackout. I’m not talking about keeping your phone charged or your EV running. These kinds of batteries
If you believe half of what you hear about heat pumps, you'd think they're a $20,000 scam that stops working the second it gets cold outside. But here's what the skeptics don't mention: modern heat pumps work in temperatures down to
NOTE: An earlier version of this story incorrectly associated the failure of Northvolt to their sodium ion battery production issues, but their challenges weren't chemistry specific. That section has been removed. I’ve got sodium batteries right here in my hands, but three sodium battery companies went bankrupt
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
