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!

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?

After that, the price stops making sense. So China built an alternative out of thin air: the world's largest compressed air battery, a salt cavern energy storage system with no lithium and no fuel burned to get the power back out. The pitch is that it beats lithium at long duration energy storage. But run the math on how long it actually lasts, and the answer comes out to 4 hours too, exactly where lithium already wins. So is China's giant air battery actually solving the long-duration problem? Or is it just an expensive peaker plant that happens to run on air?

My January electric bill came to $336, even with solar on the roof and 20 kWh of home battery storage on the garage wall. After 12 months of utility bills and circuit-level data, the solar battery math got weird. The panels saved money. The battery cost about $207 a year, thanks to net metering, round-trip losses, and the way Massachusetts credits rooftop solar. But I would still buy it again. So is a home battery actually worth it for resilience? Or is the whole thing just an expensive backup plan?

Why The US Sucks at Solar. 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 About one in three Australian homes have rooftop solar. In America, it's less than one in ten, even though half the country sits under the same sun. The real story is the bill. The rooftop solar cost here runs up to seven times higher than in Australia, once tariffs, tax credits, and solar permitting pile on top of the price tag. Australia is adding home solar batteries at a blistering pace, and its lead keeps growing. So is Australia actually better at cutting paperwork? Or is America's red tape just costing you thousands?

Why The Biggest Battery Company Is Betting On Lithium Air. Subscribe to IEEE Spectrum Magazine and get 20% off: https://spectrum.ieee.org/undecided And check out @ieeespectrum on Youtube. CATL, the world's biggest battery maker, just named its bet for what comes after solid-state batteries: lithium air. Headlines claim this battery stores as much energy as gasoline. This lithium air battery breathes, pulling oxygen straight from the surrounding air instead of packing in heavy metal cathodes. Scientists say the design could push EVs past 1,000 miles on a single charge, and a startup is already chasing it for drones and aircraft. So is this air-breathing battery actually as close to gasoline-level energy as CATL claims? Or is that number just a headline that outran the lab?

Every winter, it burns fuel to make that heat all over again. What if you could bank July's heat underground, then pull it back out in January? Aquifer thermal energy storage does exactly that. It turns the groundwater under your feet into an underground thermal battery, and the Netherlands has been running ATES this way for more than 30 years. The US Department of Energy proved the idea worked here decades ago, then let it go quiet. So is ATES actually the cheapest way to heat and cool a whole city block? Or is the Dutch head start too big for us to copy?
