In a world where the drought threatens increasingly water resources, innovation in the collection of atmospheric humidity emerges as a possible safeguard for the future. Nearly two billion people they currently suffer from water shortages, a figure expected to double by 2050 due to the escalating climate crisis. The forecasts of World Bank suggest that the demand for drinking water will increase by 55%, while available resources will decrease drastically.
The ancient art of capturing moisture to extract water from the air
The idea of extraction is not new. From millennia, different techniques have been adopted to exploit atmospheric humidity, from Nabataean farmers to modern dehumidification systems. However, the real obstacle remains energy sustainability of the process: the target is to develop methods that do not require the use of conventional energy or that they make use of exclusively of renewable sources.
A recent study on Nature highlighted two main approaches in atmospheric extraction technology: i methods passive and active ones. Passive methods, which do not require electricity, are based on the natural collection of dew. These systems can produce up to 27 liters of water per day per square meter, using sheets of polymer mesh to trap and collect water. For example, a 40 square meter collector can provide approx 200 liters of waterfall to the dayenough for 60 people.
AND’ crucial to address water scarcity in a sustainable way, especially in remote and remote regions access to energy electric. This could not only mitigate the water crisis but also offer new hope for a more resilient and self-sufficient future.
