Pieter Hoff, a Dutch 'green' inventor, utilized this principle of nature to create his celebrated Waterboxx.
Mr. Hoff was the largest grower of lilies in the Netherlands and the largest exporter of bulbs in the world when he sold his business several years ago with this stated goal: "I wanted to leave a better world for our children."
After a year the tree within the waterboxx is strong enough to grow by itself and the polypropylene structure can be removed and used again 12 more times.
Hoff explains, "Trees can grow in arid areas but are not able to germinate. The WaterBoxx gives them a head start". He recently tested his invention in the Moroccan Sahara desert with the result that 90 percent of the 3500 fruit tree saplings planted with a WaterBoxx were alive and green after a few months in the extreme hot summer. This contrasted with those trees planted without a waterboxx - there, 90 percent of the trees died even though they had been watered every week. After three years, over 88% of the waterboxx trees are rapidly growing. Now, similar studies are ongoing in Kenya and Spain and he has chosen Napa/Sonoma and Palm Springs/Joshua Tree for his United States study.
Hoff is seeking investors to apply his invention in the Middle East, India, Africa and other arid territories. Hoff maintains that "If we can reforest 2 billion hectares, the trees consume more CO2 than men produces and the whole CO2 problem will be solved."

A similar dew catching technique comes from WatAir. Each WatAir unit features 96 square meters of lightweight dew-collecting panels that gravitationally funnel moisture from the air to one collective source. The designers, Joseph Cory of Geotectura and Eyal Malka of Malka Architects from Haifa, Israel, estimate that each unit can collect roughly 48 liters of water in remote places or places that do not have any clean water sources. The panels are flexible, easy to collapse when not in use, and readily available to provide shade and even some shelter.
All these examples remind me of that magnificent Japanese movie directed by Hiroshi Teshigahara, 'Woman in the Dunes' (砂の女, Suna no onna)..I can't explain why because then it ruins the movie for you.....
