The Mystery Behind Donut Lab's "Impossible" Battery. My wife and I are loving our Roborock Saros 20. If you’d like 13 - 14% off a Roborock Saros 20 and Saros 20X from March 23 - 29, the Roborock Saros 20 is available on Roborock (US) https://bit.ly/4bI2gac (Canada) https://bit.ly/419pcZL and Amazon (US) https://amzn.to/3PicXYg (Canada) https://amzn.to/4cN4ZjF, and the customized Roborock Saros 20X package available at Target Coming Soon and Best Buy https://bestbuy.7tiv.net/oNqZPe comes with one pair of mop cloths and one 200ml cleaning solution in addition to Saros 20! 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 per pound than today's best lithium cells. No lithium. No cobalt. No hard-to-get metals. And a battery that charges in five minutes, but lasts a lifetime. Some experts say those specs are physically impossible. Others think they've already cracked the case and figured out who really built this thing and what's actually inside. We don't know yet if Donut Lab's claims will hold up. They’ve been releasing third-party tests slowly over the past few weeks. But let's take a closer look at what this battery could be… what it probably isn't... and what Donut Lab could possibly gain by exaggerating its claims. It’s not as clear-cut as you might think.

Should You Wait for the Next Solar Breakthrough? Use my code MATT at https://eightsleep.com/mattferrell for up to $350 off the Pod 5 Ultra. 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’s the better path and value? Should you wait for the next solar breakthrough technology to finally arrive, or install silicon solar panels now? Which one gives you a better bang for your buck?

Geothermal vs Air Source Heat Pump: Which is Worth It? 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, are they really worth it? Or should you go with an air source heat pump instead? I've been living with my geothermal system for two years now. I reached out to my friend Paul Braren, who installed an air source heat pump system in his home around the same time I was building mine. We're both in New England, we both have detailed energy monitoring, and we both ditched fossil fuels completely. It’s the perfect setup for a real-world comparison. Here's the thing, though. After crunching the numbers, this isn't going to be the straightforward "geothermal wins" or "air source is better" story you might expect. The actual data surprised both of us.
