Air to Water Harvest (A2WH) System
Our Solar powered Grow Dryland extracts water from the air which is delivered directly to the seedlings roots and can keep the seedling alive in locations where they would normally die from dehydration. The tree uses this water as it grows deeper roots that can allow it access soil moisture deeper underground and eventually survive without auxiliary water. Grow Dryland is ideal if you want to start trees in areas where trees can survive once they are large enough but the seedlings would die from dehydration before their roots can reach the deeper moist soil. When combined with our larger planting system Grow Dryland can even support trees in dry and barren desert locations.
A2WH technology can reliably produce water in areas where there is little or no rain; in fact it will deliver the most water during the hottest, sunny and dry parts of the year, which is when fragile seedlings need the most water. Other water storage and dew harvest devices may not have any water left during the critical part of the year when A2WH is delivering the most water. Since Grow Dryland A2WH produces water directly from the air and since it's production rises during the summer months it is completely immune to drought.
- Extracts water from the air and uses that water to keep seedlings alive in desert conditions where water and electricity are not available.
- Powered entirely by solar energy which makes it ideal for remote and hard to access locations.
- Eliminates the need to drag a hose or a bucket to every tree to provide water.
- Makes it feasible to plant trees in areas where you can not visit regularly to provide water.
- Delivers about 2 ounces of water per summer day directly to trees roots via a wick or tube.
- Support Trees in locations where it is not feasible.
- Dramatically increase the survival rate of the trees.
- Start trees along perimeter property lines without a massive effort to install a drip irrigation system.
- Each Grow Dryland can start many trees over its useful life.
- When combined with wicking drill techniques Grow Dryland can guide seedling roots into deeper subsurface moisture so it can thrive even in the dry desert.
When used with a wick system, the water collected by the A2WH unit can guide the seedling’s roots deep below the surface where soil moisture is sufficient for the tree to continue to develop and thrive. Once the plant is large enough to grow on its own the Grow Dryland can be moved to support a new seedling. When combined with a bio-sponge and land profiling techniques the A2WH unit can support tree seedlings in the most hostile and desolate conditions.
Grow Dryland is not a fog capture system and uses entirely different physics with most of the working energy being provided in the form of solar heat. Grow Dryland works well in dry desert conditions without supplemental water. Grow Dryland will deliver the most water during the hottest summer day when many other AWG (Atmospheric water generator) technologies fail.
- Start trees for to provide wind screens where irrigation is unavailable.
- Start shade and fuel trees at remote locations like camping and recreation lots where there is no water available.
- Start perimeter privacy and wind screen trees on larger lots where Grow Dryland may be easier and less expensive than installing large irrigation systems.
- Start forage trees restore grazing lands and provide drought resistant alternate food source.
- Start trees to provide habitat and shelter to attract wildlife to barren desert lots.
- Start the process of revitalizing degraded and desertified lands by starting trees that can hold moisture in the soil, reduce erosion, reduce runoff, reduce dust loads, provide habitat and aid in returning the land to healthy state.
- Support growth of plants in areas where municipal watering restrictions would prohibit the same plant.
- Establish high nitrogen biomass trees on cheaper land where no irrigation rights are available. The foliage can be used to produce traditional biomass for fuel or used to produce high nitrogen compost.
- Produce income from desert land without increasing demand on groundwater.
Grow Dryland is best combined with the rest of our planting process which can help grow trees in the most hostile hot and dry locations. Many locations only need a small portion of the planting process. Our goal is to provide the technology and process that will allow high survival rates in the most challenging conditions.
- Wicking root Drill – guides roots to naturally available water where they may never have otherwise reached.
- Bio-Sponge – Stores water from rainfall so the tree has a local reserve while providing naturally decomposing nutrition.
- Micro Land profiling – Guides water to the Bio-sponge for storage, reduces evaporative losses and helps eliminate soil erosion.
- Food and Foliage – Reduces drought related food famine.
- Nitrogen rich compost – The nitrogen rich leaves can be composted for nutritional fertilizer that holds moisture.
We fabricate these units as we receive orders in our facility near Seattle Washington. We test every unit before shipping and it can take a few weeks to work through the full process. Each unit contains the main A2WH Grow Dryland device which includes the solar electric panel and battery needed to allow it to operate. The user must supply the local planting supplies and the wick if desired.
A2WH technology is patented in the USA with international patents pending.A2WH also produces larger AWG (Atmospheric Water Generation) units which extract water from air using solar energy. A2WH units can be assembled in farms to produce thousands of gallons of water per day. We also have plans that can allow very large A2WH units that are constructed in village and can deliver hundreds of gallons of water per unit.
A2WH technology uses Solar heat for the primary energy source with a small amount of electricity to run the sensors and fans. The required electricity is supplied by the included solar panel and a battery. A2WH was designed for sunny locations and it requires sun to operate A2WH will not produce as much water during the winter or periods with heavy cloud cover. Do not purchase locations where little solar energy is available as A2WH or areas where Photo Voltaic solar panels would not be effective.
“Grow Dryland” was invented to reverse desertification worldwide. It is part of a larger program designed to revitalize large areas of degraded and desertified land. This plan centers around starting profitable trees because:
- Trees can act as the anchor for a recovery oasis
- Trees can provide biomass for compost, animal food and fuel in the short term while delivering a valuable lumber product in the long term
- Drought tolerant trees and our planting process can produce valuable foilage during drought conditions when other food sources are drastically reduced
- Trees are ideally suited to take advantage of our micro catchment and the water from 'Grow Dryland' in a way that annual crops simply can not match. This allows us to support a crop on land that simply could not support traditional agriculture.
- We can start trees using this process during the worst drought and still deliver high survival rates
- This kind of planting can rehabilitate the land without increasing groundwater demand. Demonstrating the ability to deliver a profitable crop without drawing groundwater is critical in many parts of India, Mexico, Pakistan, Texas, Oklahoma and California where over pumping of ground water is causing well levels to drop. This is especially true in Mexico and India where groundwater levels have already dropped to levels where traditional farming techniques are failing due to lack or water or increased costs to obtain the water.
- It will be most beneficial in areas with low rainfall or common drought where other approaches have failed.
- Improved water retention and microcatchment when deployed in large scale can help restore groundwater levels in degraded areas which can accelerate the restoration and revitalization of degraded land.
- Fodder trees provide an alternative animal feed that can allow local farmers to reduce their demands on natural grasses and allow those lands to start the recovery process.
- The foilage and compost from high nitrogen species such as Albizia Lebbeck and Red Alder can be added to soil of traditional fields which can improve yields as a natural fertilizer. They can also increase water retention which can increase food availability especially during drought years.
Our assertion is that we need people living in desertified areas to plant, maintain and protect the trees needed to revitalize the land. To gain their enthusiastic support they need to gain local benefits, income or food from those trees. We focus on strategies synergistic with the needs of local farmers and local villagers who we believe will make the best long term stewards. All plans require money to get started but unlike many approaches our plan can deliver a profit so it is not entirely dependent on charity or government funding.
