PROBLEM: There are places on Earth where there’s not enough rainfall to grow food.Some places hardly And some placesget any water at all. alternate between bone dry and ﬂooding.
And in some places,the water doesn’tpenetrate deepenough andevaporates before itcould nourish plants.
Two high school students from San Francisco decided to ﬁnd a solution.Nick and Tim Werby worked with UCBerkeley School of Engineering to designa cost-effective and practical product.
IDEA:Create a simpleproduct that wouldcollect atmosphericwater(dew, fog, rain)and transportit below theevaporation layerin the ground.
Condensation: Solution:• Water collects on surfaces colder • Atmospheric Water Capturethan the surrounding air • Easy Maintenance• In desert environment, this water • Easy to Understandevaporates before reaching plantroots • Cheap• Farmer can’t grow enough food • Recyclabledue to lack of irrigation even in the • Flexiblepresence of atmospheric water
Condense atmospheric water on a surface and transport it deep enoughinto the ground to keep the moisture from evaporating during the day.
EasyMaintenance No electricity; No moving parts; No supervision; Simple to make.
Simple toUnderstand Stick in the ground next to a plant.Communicate use with a pictogram.
Cheap& SmallThere are many atmosphericwater collection solutions. We focus on the cheap and the small. We are targeting poor subsistence farming populations.

D.R.I.P.S. Project 2012 Challenge: Develop a Working PrototypeMoving from concept to a fully-realized product is very hard.Tim and Nick decided to develop an inspirational prototype.Using the grant from EDF, the boys worked with artists to develop a DRIPS prototype...
There are MANYdifferent solutions to atmospheric water collection problem.DRIPSproject.com is a large library ofsolutions with links to companies that make various atmospheric watercollection systems and to research on how atmospheric water can be used in agriculture.
