Seoul's zoo has a new tram with battery that is one-fifth the size of a typical EV battery and doesn't need overhead power wires to keep it charged. The prototype is the world's first electromagnetically-charged tram. Its batteries receive a continual power charge from power strips buried along the travel path.
The Korean Advanced Institute of Science and Technology (KAIST)-built zoo train will serve as a model for electric-powered buses and proximity charged trams that can operate without overhead cables.
