Eleven years ago, an MIT physics professor named Marin Soljačić demonstrated a technology with the potential to render cords obsolete. He and his colleagues sent power wirelessly from a transmitter to a 60-watt light bulb about 7 feet away, using specially tuned magnetic fields. They dubbed the technology WiTricity — like WiFi for electricity — and soon started a company to bring it to market.
