The need for water is vital in many parts of the world without the infrastructure to supply safe drinking water. There are many personal technologies that can be used water purification or water gathering. While the view of a self-filling water bottle may at first sound like magic, it’s based on nanotechnology and biomimicry.

NBD Nano is named for the Namib Desert Beetle, whose shell functions to gather water for the insect,

and which served as the inspiration for the technology. The technique behind this uses hydrophilic (water retaining) and hydrophobic (water repelling) coatings to concentrate moisture in the air onto the hydrophilic surfaces, and next, as the droplets become big decent, the water runs into a central collector. A small fan is used to move air by the surface to improve collection.

The company is pursuing a variety of possible applications for […]
