Intelligent upgrades MORE than 3,500 kilometers of highways in China have completed intelligent upgrades, according to the 2023 Digital Transportation Conference and Expo (Beijing), which opened Monday in Beijing. The construction of intelligent scenarios, such as lane-level management, intelligent monitoring and early warning, and off-site law enforcement, has seen positive results. The quality of China’s travel services has continued to improve as the country deepens the application of information infrastructure, such as the BeiDou Navigation Satellite System and 5G technology. Trial cruise line NORTH China’s Tianjin Municipality has launched a new trial cruise line along the Ziya River, a branch of the Haihe River, aiming to inject vitality into the riverside tourism industry. During the approximately 80-minute voyage, tourists can enjoy many of the city’s tourist attractions, including the Ferris wheel “Tianjin Eye.” Renewable energy CHINESE scientists and engineers have completed an offshore test of an ocean thermal energy electricity generation device in the South China Sea. Ocean thermal energy harnesses temperature differences between the surface and deep seawater to generate electricity, thus being a source of renewable energy. During the test, the device generated electricity for four hours and 47 minutes, reaching a maximum power output of 16.4 kW. |
