California and parts of the south-west are currently experiencing an unprecedented drought. If this drought continues the global agricultural system could become unstable. Consider this: California and Arizona account for about 98 percent of commercial lettuce production in the United States.
Are we doomed? Will Matthew McConaughey save us? Will Tars?
Thankfully we don’t live in Christopher Nolan’s world. We live in a world filled with exponential innovation. We actually have an emerging technology called Atmospheric Water Harvesting that could save California from its current drought and possibly change the techno-agricultural landscape forever.
Traditional agricultural farming methods consume 80% of the water in California. According to the California Agricultural Resource Directory of 2009, California grows 99% of the U.S. almonds, artichokes, and walnuts; 97% of the kiwis, apricots and plums; 96% of the figs, olives and nectarines; 95% of celery and garlic; 88% of strawberries and lemons; 74% of peaches; 69% of carrots; 62% of tangerines and the list goes on.
Several companies around the world are already using atmospheric water harvesting technologies to solve this problem. Each company has a different technological approach but all of them combined could help alleviate areas suffering from water shortages.
The most basic, and possibly the most accessible, form of atmospheric water harvesting technology works by collecting water and moisture from the atmosphere using micro netting. These micro nets collect water that drains down into a collection chamber. This fresh water can then be stored or channelled into homes and farms as needed.

Atmospheric Water Solutions ABY-C AquaBoy Rolling Cabinet Floor Stand
Aqua Sciences’ flagship product is the Emergency Water Station (EWS). The 40 foot model produces up to 2,600 gallons of water per day (depending on local atmospheric conditions). Specially designed for transport by air, sea or land in an International Standards Organization (ISO) marine container, the Aqua Sciences EWS is powered by self-contained electrical generators or external power. It is a compelling first and ongoing response solution for areas with damaged or no infrastructure throughout the world.
• 1.2 billion people lack access to clean drinking water (UN).
• By 2025 that number will more than double to 2.8 billion (UN).
• Annual deaths from diseases caused by poor drinking water and sanitation: 10 million.
• Excellent Water Quality: Meets and exceeds US EPA (Environmental Protection Agency), World Health Organization and US Military specifications.
• Significant Water Quantity: Provides drinking water for up to 5,200 people per day. (Per FEMA (Federal Emergency Management Agency), a normally active person needs 0.5 to 1 gallon per day for drinking.)
• Proven: Successfully deployed in the largest natural disaster in the history of the Western Hemisphere in early 2010 by a US Southern Command mission and saved lives at the University Hospital in Port Au Prince. Consistently made water and met customer needs during a 37-day desert test at a 100-person oil rig in the Middle East in the summer of 2010. Aqua Sciences has won highly competitive procurements issued by the US Army and FEMA.
• Cost-effective: Highly competitive in cost and more economical than existing solutions in areas of need.
• Fully “Off the Grid”: Does not require outside water or power to generate drinking water. Since the machine extracts only water molecules from the air, it eliminates the need for complex and high-maintenance filtration systems such as Reverse Osmosis Purification (ROWPU). It is ideal for areas with contaminated groundwater.
• Works in Virtually Any Environment, even in Desert Conditions: Aqua Sciences systems are NOT conventional refrigerant dehumidification (CRD) systems that condense water by cooling ambient air to the dew point and that are not suitable for low humidity conditions.
• Scalable: Aqua Sciences systems can be built for daily water needs of less than a hundred people to several thousand.
