Problem addressed

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.

Innovation
  • By ingeniously integrating these components, the portable FSS as an eco-friendly battery may not only charge small electronic products but also sustainably supply freshwater in remote areas.
Key impact
  • Made by 3D printing to suit for different configuration in various scenarios
  • Utilized ambient moisture to generate electricity and harvest freshwater concurrently
  • Low cost of maintenance and operation
  • Long lifetime, easy assembling, and flexible scale
Award
  • Gold Medal with Congratulations of Jury at Inventions Geneva Evaluation Days 2022
Application
  • Generating electricity from the sustainable source of ambient moisture in remote area
  • Harvesting freshwater from atmospheric moisture
