Some things that collect water from the air are quite large, such as fog harvesters. Some are very expensive: air water condenser turbine. Some are very small: the desert beetle dew harvester. And some are inexpensive: Tal-Ya irrigators (only $1.00 each).
We believe that D.R.I.P.S., being small and inexpensive, would be useful to individual farmers in areas where dew readily forms.
