The project "Fog-to-electricity Generator with Ultra-high Power Density” received the Gold Medal with Congratulations of the Jury at Inventions Geneva Evaluation Days (IGED) 2022. IGED is the world's most important annual event devoted exclusively to invention.
The research team of the winning project has founded a start-up, which is supported by CityU’s flagship entrepreneurship programme HK Tech 300, to transfer the technology into actual application.
The research team has introduced the first-ever fog-powered green generator for harvesting energy and freshwater from moisture. It combines a newly developed high-power density droplet-based energy generator (DEG) with a nature-inspired, superhydrophobic fog harvesting mesh. This new technology can produce a record-high power (300 V), with a water collection rate of approximately 250 litre per square meter per day. This dual electricity generator and fog harvester has the highest fogbased energy-conversion efficiency reported to date. It provides a sustainable, stable, low-cost, portable, and eco-friendly power supply solution, while simultaneously tackling the freshwater crisis in many major cities and areas.
