Exploring fog harvesting technologies as an alternative source of water through a technique used to capture water from wind driven fog in the winter and humidity during hot summer days using nature-based solutions; tensile membrane structures towards resource efficient cities.
As the world’s population and the demand for fresh water continue to grow, greater stress is placed on current sources of potable water. To preserve global water supplies, it is imperative that alternative and sustainable technologies for the collection and distribution of fresh water be explored. The Nebula project is a smart fog harvesting system developed in the Po River Valley region (Pianura Padana) located north of Italy and holds one of the highest amounts of radiation fog in the world. Through fog harvesting technologies, urban environments can decrease pressure on local water reservoirs in low water availability periods and provide a way of capturing vital water supplies in coastal, high-altitude, desert, mountainous, and forested regions. On average, water production rates from fog collectors range from 200 to 1,000 liters per day, with variability occurring on a daily and seasonal basis.
