The availability of freshwater is persistently changing, and the current trends indicate that it is declining very rapidly, both quantitatively and qualitatively around the globe. Therefore, the shortage of freshwater will pose the biggest threat to mankind, and hence, there is an urgent need to develop and demonstrate new and sustainable technologies to address the issue. Atmospheric water generation technologies, which generate water from the air, has been untapped so far and could be an emerging alternative to tackle this issue. However, these technologies have been energy-intensive, which actually limits their widespread deployment in the field. The performance of various technologies has been summarized and compared in terms of their important performance parameters, constraints and advancements. The technological solutions to some of the current issues, retarding the growth of these technology have also been identified and discussed. Further, it is found that the advancement of some of these technologies is still in the nascent stage, and could not emerge as an economically viable solution. Thus, there is immense scope to explore atmospheric water generation and transform it into a feasible futuristic solution to water scarcity. Therefore, this review aims to provide the technical insight to re-examine the available technologies, research gaps and scope for further advancements.

淡水的供应量一直在变化，目前的趋势表明，全球范围内的淡水数量和质量都在迅速下降。因此，淡水的短缺将对人类构成最大的威胁，因此，迫切需要开发和展示新的可持续技术来解决这一问题。迄今为止，尚未开发利用大气中的空气来产生水的大气水产生技术，并且可以成为解决这一问题的新兴选择。但是，这些技术消耗大量能源，实际上限制了它们在该领域的广泛部署。总结了各种技术的性能，并根据其重要的性能参数，约束条件和进步进行了比较。已经确定并讨论了解决一些当前问题的技术解决方案，这些问题阻碍了这些技术的发展。此外，发现这些技术中的一些技术仍处于萌芽阶段，并且不可能作为经济上可行的解决方案出现。因此，探索大气中的水产生并将其转变为解决缺水问题的可行的未来派解决方案具有广阔的空间。因此，本综述旨在提供技术见解，以重新审视可用技术，研究差距和进一步发展的范围。探索大气中的水产生并将其转化为可行的，未来的解决水资源短缺的方法的范围非常广泛。因此，本综述旨在提供技术见解，以重新审视可用技术，研究差距和进一步发展的范围。探索大气中的水产生并将其转化为可行的，未来的解决水资源短缺的方法的范围非常广泛。因此，本综述旨在提供技术见解，以重新审视可用技术，研究差距和进一步发展的范围。
