Dear MEL Topic Readers,
Fog harp makes water out of thin air
Just as electricity is generated by solar panels or wind turbines, water can be collected from relatively easily-available natural resource. Fog collection. As the exposed surface of fog-collection net cools in the morning or evening, moisture in the air condenses faster than it evaporates, and then water droplets are formed. The droplets, or dew, then flow down towards a trough below the fog net, providing precious water for people, plants, and livestock in dry areas. This idea has been practiced since the 1980s in many parts of the world, such as South America, Africa, Asia and the Middle East where water is scarce.
In our mother nature, this phenomenon is observed on plant leaves and blades of grass, creating dew. So, researchers at Virginia Tech University have developed more efficient fog net by observing plants’ leaves and branches. They call it fog harp because of its appearance.
Nature has evolved over billions of years. There seem to be a lot to learn and earn from nature.
Enjoy reading and learn about fog harp.
