Scientists generate electricity from ambient moisture using everyday ingredients

In a study published in Nano Energy, researchers from Queen Mary, the University of Warwick, Imperial College London, and Universitas Mercatorum report a highly stable, biodegradable Moisture-Electric Generator (MEG). The device is fabricated from food-grade materials including gelatin, sodium chloride (table salt), and activated carbon, and harnesses humidity—typically a major challenge for electronics—as its energy source.
