Flint's paper battery is real and it doesn't need lithium
Paper is an unexpected starting point for a rechargeable battery, which is part of Flint's appeal. The Singapore-based company uses cellulose, the plant-derived material in paper, to build something that stores energy without lithium. That alone makes it worth a second look. Flint's battery is real, rechargeable, and skips the geopolitical headache of lithium mining entirely. It's the kind of quiet, weirdly elegant detail that makes you wonder why nobody thought of it sooner. It won't power your car, but it might power the disposable sensors, smart labels, or medical patches that currently rely on single-use coin cells. That matters. If you enjoyed this kind of deep curiosity about how things actually work, you should poke through our look at Logitech's surgical XR controller concept, another piece of hardware that refuses to be obvious.
This $249 Lock Still Opens When Its Battery Gives Up
Smart locks sound like the future until you're standing outside with groceries and the lock won't wake up because of a dead battery. Although there are backup keys, most of us will discover we left them inside just about the time the lock goes silent. This one, a $249 model, quietly solves that by still opening when the battery gives up. It's not a party trick. It's the difference between a product that respects your forgetfulness and one that punishes it. The clever bit isn't the app or the Bluetooth pairing, it's the mechanical fail-safe that doesn't require you to have planned ahead. Spoot loves a detail that admits you're human. If a smart lock can't handle a dead battery, it's not smart. It's just a door that's learned to say no.
