The Development Bureau (DEVB), the Electrical and Mechanical Services Department (EMSD), and the Drainage Services Department (DSD) presented 18 invention projects at the 50th International Exhibition of Inventions of Geneva and achieved outstanding results by winning 20 awards, comprising one Prize of the Republic and Canton of Geneva, one Prize of the Best International Invention and Innovation, three gold medals with the congratulations of jury, five gold medals, five silver medals, and five bronze medals (see Annex). The International Exhibition of Inventions of Geneva, which was held from April 9 to 13 in Geneva, Switzerland, is one of the most significant global annual events on inventions. About 1 050 inventions from 35 countries and regions were evaluated by the international jury of specialists.
      
     The Secretary for Development, Ms Bernadette Linn, extended her heartfelt congratulations to the teams from the Works Branch of the DEVB, the EMSD and the DSD for winning multiple awards. She said, "The DEVB and works departments have been continuously promoting technological transformation and actively adopting innovative technologies. This has not only significantly enhanced the operational efficiency of public works projects and services, but also effectively improved cost-effectiveness. The teams have been dedicated and committed to striving for excellence in technological research and its transformation into practical solutions. The awards received in this international mega event fully demonstrated that their efforts and accomplishments have been recognised internationally."
      
     The Two-phase Immersion Cooling System for High Performance Computer Workstation, which was jointly developed by the EMSD and the Civil Aviation Department (CAD), won the prize of the Republic and Canton of Geneva, marking the first time that departments of the Hong Kong Special Administrative Region Government have received this prize. The system provides highly efficient heat dissipation capability by immersing heat-generating computer components into a sealed container filled with non-conductive cooling liquid. This not only improves equipment performance and extends the equipment life time, but also achieves more efficient energy saving. The system has been successfully applied in the CAD's air traffic control tower simulator.
      
     The Secretary for Development also appreciated that the SmartEye, a remote site supervision system and integrated site management platform developed by the Works Branch of the DEVB, has won awards. This system adopts advanced technologies, including 4D LiDAR and AI for real-time monitoring of construction projects, ensuring quality and site safety while enhancing supervision efficiency. It has been successfully applied in several public works projects.
      
     The Mosaic Model Map (M³) project by the DSD was awarded the gold medal with the congratulations of jury. This real-time territorial flood risk visualisation system leveraging Hydraulic Model Pre-run, Scenario Mapping and Mosaic Compilation technologies will facilitate the DSD in timely resource deployment for speedy responses to possible flood situations under adverse weather. The Integration of AI and Optical Fiber Technology for district cooling/heating system plants by the EMSD and the Tracking Solution for Outdoor Activity Safety by the EMSD in collaboration with the CAD also garnered gold medals with the congratulations of jury.
