Confronting Water Scarcity Drop By Drop


As the challenge of water scarcity has grown globally, fog harvesters—hydrophilic mesh sheets stretched across vertical posts—have emerged as an inexpensive and accessible way to collect water from air. Unfortunately, today’s harvesters are inefficient because water droplets often escape through the mesh if the wires are sized incorrectly.
Park’s research could further the design of new, more efficient fog harvesters. His finding could also help researchers optimize other environmental processes, including mist elimination, filtration, oil/water separation, and microplastics collection.
