The Fresh Water Fog Nets Challenge

Water is one of Earth’s most precious resources. NBD Nano is developing a new generation of fog collecting nets to help provide relief for drought-affected areas around the world. Fog harvesting has been used for centuries in places like South America, proving plenty of clean drinking water for remote villages. Unfortunately, the ripe conditions for fog harvesting that are present in South America are not prevalent in most places of the world. Conventional nets simply don’t workAim: Design an equipment for converting fog into water. It should be simple, low-cost to manufacture and easy to set up at any location, primarily in high-altitude settings.This design is made up of parts that can be machined and moulded separately, with the only special equipment being the mesh. The design allows a full 360-degree rotation and height adjustment. The setup is broken into 4 main sections.• The top- The mesh, mesh stand and connecting rod.• The middle - The water collector and water collecting stand (WCS).• The bottom - The tripod and stabilizer.• Accessories - The storage container, rubber tube, pegs, and ropes.The mesh will have a fabric sewn to it upper and bottom edges to secure the mesh to the connecting rods which will put the mesh in tension hence requires minimal handling of the net. The bottom edge of the mesh will only be connected from the corners of the mesh (with a hook-like connecting rod) to allow the water droplet to fall into the water collector.The water collector has two drain holes to increase drainage from both sides. The water collecting stand feeds through the tripod which is then secured by the supports (with bolt and nuts) at the height needed.To avoid excess rotation, the upper section of the water collector stand can be secured with a rope which extends to the ground on both sides. Stabilisers are at the base of the water collector stand, which can be secured to the ground with a screw and extra sandbags for increased stability. This same principle applies to the tripod legs.
