  • How Solar Panels Make It Rain In The Desert

    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.

    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?

  • Why China Built the World's Largest Air Battery

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?

  • How My Home Battery Really Performed (2 Years Later)
    2026/09/08

    How My Home Battery Really Performed (2 Years Later). 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! 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
    2026/08/25

    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
    2026/08/18

    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?

    The Magnet Breakthrough China Doesn’t Control. 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! You're hearing this through speakers run by magnets, and your smartphone might hide another 18 of them. Most of us ignore them until the supply chain snaps. China's rare earth export controls did exactly that. Now there's a new iron nitride magnet, made from just iron and nitrogen, two of the most abundant elements on Earth, and Niron Magnetics has broken ground on a factory to build it at scale. A second rare earth free magnet gets more stubborn as it heats up. So are these magnets ready to replace neodymium magnets? Or is this just proof of how hard rare earths are to replace?
