There’s a very interesting project being launched in Qatar this month — sea water is collected by evaporators and used to create an oasis in the middle of a desert: The ultimate aim of the Sahara Forest Project is to return vast areas of desert back to life, providing food, water and clean energy...

We found another design solution for dew collection: WATERBOXX. Groasis waterboxx was elected Popular Science’s 2010 Best Innovation of the Year. Waterboxx was invented by Pieter Hoff. His ideas was to help trees grow in dry environments and replant the desert. The idea is to catch rain water and dew and store it inside...

The more research we do, the more we post on this site, the more obvious is becomes that different areas of the world, different peoples are need the flexibility in the approach to developing dew collection systems for plan irrigation. Some places have a lot of fog and would benefit from using nets-based D.R.I.P.S....

This is a very old science educational video (my mom worked on it). See if you recognize the little boy in the video… Oh, and it shows how to make fresh water from seawater through evaporation and dew formation (start at about 9 minutes into the video):

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 doing a lot of research in these last few days. We came across a dew irrigation system that had a lot of similarity to our D.R.I.P.S. project. It is a system designed by an Israeli company Tal-Ya. Here are few photos of their product (notice the irrigation lines): At first it was...

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...

We just came across this non-profit organization while we were doing a bit of additional research on dew collection and dew “harvesting.” Here’s a link: http://www.opur.fr/index.htm

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....
