Biomimicry and a Desert Beetle

To copy the way a desert beetle gets water, scientists have designed a membrane that can extract water from the air. Since all air contains water, even in the desert, this could provide a very inexpensive way to supply drinking water. This process is called “biomimicry,” or using ideas from nature to solve technological problems. This discovery could lead to reusable water bottles that refill themselves. Listen to learn why this invention would be inexpensive and how close scientists are coming to making it work.
