What if all the heat your car engine, a factory, or a power plant throws away could run the grid instead? A new engine turns that waste heat into electricity, even the low-grade stuff today's best systems struggle with. It has no moving parts, and the wild part is who built it. Dr. Lonnie Johnson, t
There's $67 billion in critical minerals sitting in your trash can right now. Old laptops, dead drills, that printer you keep meaning to throw out. The piles of waste outside old mines hold even more. By some estimates, between e-waste recycling and mine tailings, America already has nearly all the
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
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,
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
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
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
If you or someone you love has ever undergone chemotherapy, you know how brutal it can be. The drugs attack both cancer cells and healthy ones, too, leaving patients sick, weak, and exhausted. Or think about a stroke. Every minute a blood clot blocks blood flow, brain cells are dying.
Google just built a computer that solved a problem in 5 minutes that would take our best supercomputers 10 septillion years … that's not a typo. That's a 10 with 24 zeros after it. The universe is only 13.8 billion years old, so we're
