☀️ Molecule Stores Sunlight for 3 Years, Boils Water in 0.5 Seconds
Scientists created a game-changing molecule that captures sunlight, stores the energy in chemical bonds for up to 3 YEARS, and releases it as heat on demand—powerful enough to boil water in half a second. The pyrimidone-based compound stores 1.65 MJ/kg (more than lithium batteries!) and works in water, making it perfect for building heating. "We can recycle the molecule as fuel instead of burning it," says UC Santa Barbara's Dr. Grace Han. Charge it with light, trigger heat release with acid or warmth, reuse indefinitely—no emissions, no waste. Inspired by DNA damage chemistry, the breakthrough (published in Science) could revolutionize how we store and use solar energy. Half of global energy goes to heating—this tackles that challenge. Simple to make, stable for years, and recyclable: the holy grail of solar thermal storage. From summer sun to winter warmth—stored in molecules. 🌞💧
