Artificial atmospheric water generation refers to the process of creating fresh water by extracting it from the humidity present in the atmosphere. This innovative approach aims to address water scarcity, especially in regions facing water stress and landlocked areas. Let’s delve into the details:

1. Concept and Challenges:

o Water Scarcity: The lack of access to clean water is a pressing global challenge. Approximately one-third of the world’s population lacks access to clean water, and this situation is expected to worsen due to factors like population growth, urbanization, and climate change.

o Atmospheric Water Generation (AWG): AWG extracts water from the atmospheric humidity. It can serve as a lifeline for people living in water-stressed regions.

o Challenges: Despite its potential, AWG faces challenges such as energy consumption, cost, operational limitations, and scalability. Changes in environmental conditions impact AWG system performance.

o Techniques: Various techniques are used for atmospheric water generation, including active refrigeration, passive cooling and collection, vapor concentration, and hybrid approaches.

2. Fog Harvesting:

o Fog nets are vertical mesh-like structures that allow fog droplets to coalesce and grow. Large drops driven by gravity are collected for further use.

o Potentially extractable water exists in the atmosphere in the form of fog and water vapor. Fog harvesting is one method to extract atmospheric water.

3. Practical Applications:

o MD Consortium Researchers have successfully collected water from artificially created fog, breaking down organic compounds and pollutants. This technology has the potential to provide clean water in challenging environments.

o Methods: AWG can use fog harvesting, active refrigeration, or sorption to generate potable water from the air. Fog harvesting, for instance, increases water condensation using mesh devices under high humidity conditions.

In summary, artificial atmospheric water generation holds promise as a sustainable solution to water scarcity, utilizing the abundant water present in our atmosphere.
