This wearable adventure accessory called the Portable Water Storage Unit utilizes bug-biomimicry to harvest water vapor in the driest of areas. Inspired by the Namib desert beetle, the backpack gathers water from the air using nanoscale bumps with hydrophilic (water attracting) tips and hydrophobic (water repelling) sides. When aimed at morning fog, droplets will materialize and fall down channels into a reservoir for drinking.
