ICYMI - "Imagine walking into a room where your phone, laptop, and smartwatch begin charging automatically—no cables, no plugs, no charging pads to align perfectly. This vision of wireless electricity, long confined to science fiction, has taken a major leap toward reality as Finnish researchers successfully test systems that transmit electrical power through the air. Research teams from the University of Helsinki, University of Oulu, and Aalto University, working alongside Finnish tech companies, have demonstrated practical wireless power transmission using multiple innovative approaches including ultrasonic sound waves, electromagnetic fields, and advanced radio frequency systems."
