China has created a system that effectively extracts water from the air 

Scientists at Jiao Tong University in Shanghai (China) have made significant progress in the field of removing water from the air, presenting the latest greases that can absorb moisture using solar energy.
Despite significant advances in the laboratory, the productivity of the freshwater extraction process is still limited by slow adsorption kinetics, high heat of vaporization of water, and condensation efficiency. However, the tests conducted showed the potential to obtain 3.82 liters of water per 1 kg of sorbent per day in summer and 2.98 liters of water per 1 kg of sorbent in winter at about 60% and 30% relative humidity, respectively.
Advances in the field of solar water extraction from the air open up new perspectives for solving the problem of freshwater availability in real-world conditions. The implementation strategy proposed in this study promises an efficient path to the introduction of this technology, confirming its adaptability and the possibility of high freshwater production in practice.
