OK, air and light. Air contains water and light contains energy. So it is possible to extract water from air using light. In fact some substances can do it without added energy (but then you need to get the water out of the substance).

As you say, it is likely to be a low yield operation, and I can't help wondering what need exactly it proposes to fill (regardless of whether it works or not). The number of people lost in some desert desperate for a few mouthfuls of water is not much of a business proposition.
