Here’s an illustration of how D.R.I.P.S. would be used to farm potatoes, using evapotranspiration—by collecting dew and delivering it to the plants’ root system. This is our low energy passive irrigation system in scarce water environment.

We are working on our movie for the D.R.I.P.S. presentation in Paris this summer. To really explain how our invention would work, we need to give a few definitions and provide some physics background. So this post is a collection of useful concepts and definitions about water in the air. The Hydrologic Cycle This...

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 thought it would be appropriate to show you where we think D.R.I.P.S....

Who knew? There’s actually a conference that’s dedicated to dew collection! Check it out: http://fogconference2013.org/ Here’s their announcement: “The 6th International Conference on Fog, Fog Collection and Dew will be held in Yokohama, Japan, 19-24 May, 2013. The goal of this conference is to bring together people who are interested in any aspect of...

We are trying to think out-the-box, or a cone, in our case. In a very interesting video, an engineering class proposed a dew harvester constructed from a metal mesh coated with a hydrophobic layer. This approach would increase the total surface area thereby increasing the average amount of dew that could be collected. Nick...

Recently, we’ve been busy contemplating about our D.R.I.P.S. idea. We’ve even started putting together a prototype! (Although being in high school it’s a little more difficult.) We’ve considered various materials: clay, plastic, metal. We want to design something that the local population can easily produce themselves. We assume that cost of production is a...

We’re continuing the difficult task of researching the dew collection process. I’ll post a few links in our research section shortly. But the big news today is that we’re going to France to present our D.R.I.P.S. idea. We’ve been working on this for several years (since about 2008). EDF Sustainable Design Challenge gave us...

Published in the International Journal of Civil and Environmental Engineering 1:2 2009, this experiment titled Dew and Rain Water Collection in South Croatia, researched and designed by Daniel Beysens, Imad Lekouch, Marina Mileta, Iryna Milimouk and Marc Muselli, demonstrates the potential of dew collection as a significant supplementary source of water in arid environments....
