The invented technology relates to a new ventilation system that can thoroughly filter viral particles and quickly stop the spread of infectious virus, such as Covid-19, in the air and at low cost. The fast-track ventilation system is easy to install and can be used in high-risk places such as hospitals and washrooms, effectively reducing the risk of virus transmission. The enclosed ventilation system has a pipe frame made of polyvinyl chloride (PVC) with extraction ports.

The present technology relates to a novel system of harvesting energy and freshwater from high-humidity air via the 3D printed Fog-based Self-powered System (FSS), which consists the components of a fog harvesting mash with bioinspired material, a droplet distributor, a newly developed high-power density droplet-based generator (DEG), and a water reservoir.
