Let’s face it – thermoses haven’t exactly been the rockstars of innovation. Most of us picture that clunky metal cylinder Grandma used for lukewarm tea. But hold onto your mittens, because phase change energy storage thermos patents are flipping the script. Imagine a bottle that keeps drinks ice-cold for 24 hours without sweat-inducing insulation…or one that maintains soup at perfect "scald-your-tongue" temps during a ski trip. That’s the magic of PCM (phase change material) technology, and the patents behind it are hotter than a barista’s espresso machine. [2020-04-19 06:34]
