There are many personal technologies that can be used water purification or water gathering.

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.
