After Years of Perovskite Promises, Does This One Deliver? Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided A California startup called Tandem PV says it has built the most efficient solar panel on the planet, hitting 30.4% efficiency where today's best silicon solar panels top out around 25%. That number came from the company's own lab, and the test module is barely bigger than a coaster. On the same day, a rival posted an independently verified result that beat it anyway. Perovskite solar panels have promised this kind of efficiency leap for years, but durability has always been the catch, and Tandem PV says it finally solved it. So is this really the world's most efficient solar panel? Or is Tandem PV's big claim more marketing than reality?

Massive thanks to @TwoBitDaVinci for hosting this one!

How Solar Panels Make It Rain In The Desert. Start your 7-day free trial + unlock 4 extra months of Surfshark VPN — head to https://surfshark.com/undecided or use code UNDECIDED at checkout! Solar panels have one job: turn sunlight into electricity. German scientists think panels can pull double duty and trigger solar induced rainfall in the desert. The United Arab Emirates handed the team $1.5 million for a UAE rain enhancement push, betting a big enough solar farm could pull water out of the sky for tens of thousands of people. But turning solar farms into rainmakers counts as solar geoengineering, and that comes with real risks and messy tradeoffs. So is solar powered rain actually a fix for the world's driest places? Or is this desert rainmaking scheme just an expensive long shot?

Why Small Reactors Just Had Their Best Year Ever. Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided Three years ago, small modular reactors looked finished. NuScale's flagship project collapsed under massive cost overruns, and the customers walked. I said the same thing every time I covered these reactors: promising, but unproven. Now nuclear energy is having its best year in decades. New projects are breaking ground for the first time in a decade, and the federal government has made $900 million available to back small modular reactors. So is this really the year small nuclear finally works? Or are we just watching the same expensive promises dressed up in new headlines?
