Setting it up
The system needs a starting phase during which it stores energy and its efficiency is progressively increased. Once the expected operating flow is reached, the system operates continuously with only slight variations in efficiency as a function of the local atmospheric conditions and the alternation between day and night.
It is even possible to further increase the systems’ efficiency and stability by using part of the water produced to restore natural hydrographic systems in the surrounding area. The environment near the system will be covered progressively with vegetation and the moisture of the area will increase as the area extends, providing the possibility to extract a larger quantity of water.
Water in the soil
Competition & existing market
Many passive and active system have attempted to extract water from the air. Unfortunately, they currently have drawbacks that makes them non-sustainable for our purpose:
- Existing active systems have a low production and the energy cost to pay for electricity is high. Moreover, many regions remain totally isolated from any (clean) electricity sources.
- Existing passive systems are currently only able to extract small amounts of water and any pollution present in the air is found in the water. These passive systems are also highly dependent on atmospheric conditions (or simply don’t work at night), making them poor candidates for catering large human facilities.
It is therefore necessary to rapidly develop a technology that allows the construction of plants capable of supplying cities. Smaller scales could provide water for domestic needs.
- Longer periods without sun reduce the systems’ efficiency drastically. Therefore, the polar regions are unfavorable to the implementation of such a system.
- The produced water is too pure for direct consumption (before mineralization), but ideal for agriculture and industrial needs.
