Upon evaluation of different criteria of the ideas, it is found that extracting water from air using hydrogel is the most viable choice. Its values lie in being cost effectiveness, availability of parts, ease of use and ease of maintenance. Even though its rate of clean water that can be obtained is not that high, the amount of water obtained is sufficient for daily consumption. Therefore, idea 1 is the most viable for further improvement.
