Ever wish you could bottle up all that wasted heat from your oven or radiator? Japanese scientists just made it possible with super-thin nanosheets that trap and store heat—even at low temps. Imagine saving on your energy bill by reusing heat that would otherwise disappear. This tech could mean cheaper, greener homes and factories, and maybe even portable gadgets that run on leftover warmth. The future of energy might be as thin as a noodle! #Business #Industry #EnergyHacks
