They look like abstract sculptures- skeletal ghosts of vases- but they’ve been carefully designed to harvest moisture from the atmosphere and can be built with locally available materials.
Called WarkaWater towers, each pillar is comprised of two sections: a semi-rigid exoskeleton built by tying stalks of juncus or bamboo together and an internal plastic mesh, reminiscent of the bags oranges come in. The nylon and polypropylene fibres act as a scaffold for condensation, and as the droplets of dew form, they follow the mesh into a basin at the base of the structure.
