Step aboard the "Star of East Lake," a 58-seat electric sightseeing boat that can travel 33 km over about six hours on a single charge. It recharges in just two hours and cuts roughly 100 tonnes of CO₂ emissions annually compared with a diesel boat of the same size. CGTN's Liu Jiaxin takes a ride to explore how electric propulsion is expanding beyond sightseeing boats, paving the way for zero-carbon harbors and, eventually, electric ocean-going vessels.
