Matt Ferrell lives in the Boston area and is a UI/UX designer by trade, but has always been obsessed by technology and how it works. In 2018 he started his YouTube channel, Undecided with Matt Ferrell, where he explores sustainable and smart technologies like EVs, solar panels, and smart homes.
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
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.
What if I told you there's a way to get up to 30% more power from the same solar panel footprint? No breakthrough chemistry. No quantum physics. Just one simple change that’s finally starting to catch on. They're finally putting solar cells on both sides
Caribbean beaches are ankle-deep in slimy, smelly seaweed. Wave after wave of sargassum is blanketing shorelines from Barbados to Cancún. It traps sea turtles. It smothers coral reefs. And it drives tourists away from islands that depend on them. This seaweed isn't just crashing weddings on the beach.
This summer, the United States made a $559 billion decision. The consequences of that decision could make your next car $7,500 more expensive and send your electricity bills soaring unpredictably…if they aren’t already. On July 4th, 2025, President Trump signed the "One Big Beautiful Bill Act&
What if I told you the world's largest battery company just announced batteries that cost as low as $10 per kilowatt hour? Not $100. Ten. That's like going from paying for a luxury car to buying a bicycle. And the kicker? They're not using
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
This Battery Has Blood In It (Kinda). What if the secret to next-generation batteries is circulating in your blood, and the blueprint for powering AR contact lenses is swimming in the Amazon? Humans have been building batteries for a couple hundred years, but nature has been perfecting energy systems for
Two and a half years ago, I told you about a company using "death rays" to drill deeper into the Earth than anyone has before. The goal? Unlock cheaper and more plentiful geothermal energy for the world. Well, I just got back from Houston, Texas, where I watched
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
When we talk about the circular economy, we picture batteries stripped for their metals, factory floor scraps spun into sweaters, and agricultural waste transformed into biogas. We don’t picture mucking out the barn to collect material for surgical masks and food packaging. Engineers are constantly looking for ways to
Imagine a world where the homes we live in, the clothes we wear, and even the sensors in our electronics weren’t manufactured, but grown. Mycelium, the root structure of fungi, is shaking up everything from sustainable construction to meatless bacon. It’s turning agricultural waste into walls, hemp into
