An alternative way to produce drinking water which does not involve access to surface or groundwater is to generate water from humidity. This is a technology which can be operated exclusively on regenerative energy sources.
To begin with, atmospheric humidity is absorbed from a highly concentrated salt solution. The bound water is then distilled from the circulating salt solution. The distilling plant is designed as a gravitation-supported vacuum evaporator to make it run at the lowest possible evaporation temperatures.
The process is easy to set up, cost-efficient and independent of all kinds of infrastructure so that it is highly suitable for decentralized water generation.
