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.
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.
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.
We designed these units so they can be lashed to the top of a refugee shack to produce survival water or staked to the ground for people camping or remote mining sites and mobile scientific bases. They can also be easily intalled wherever there is full sun. They are small enough to pack in a basement or closet for those living in earthquake and hurricane zones and then they can be pulled out and set up quick after the disaster.
For emergency response hundreds of new mobile A2WH units can be stored in a single 20 foot cargo unit and then delivered by helicopter for rapid setup. Once they are in place there is no further need haul in water so you can focus on providing medicine, food and shelter.
We are accepting reservations for orders from people in the USA for quantity 15 orders. Do not send us money but rather send an email indicating how many units you are comitting to buy at that cost. Once we have enough orders accumulated to run a production run (minimum 1,000) units we will contact you to pay for your units. If you do not pay at that time you will go to the end of queue for the next production run. We reserve the right to request a deposit to reserve your spot in the production queue. The costs may change as our materials costs change but once we accept your payment in full then we lock in your price. These units may not be exported without our explicit written permission
For those who just can not wait we can produce these units at $4,500 each for quantity 10. We hand produce these short runs in our lab near Seattle WA. The advantage of these units is that they are extensively tested at every step. This disadvantage is that they do not look quite as polished as the large run units.
Production versions are approximately 60 inch by 60 inch"
For international shipments we add the cost of local patent to the first shipment into the country. That means your first order will cost an additional $3,500 to $18,000 depending on the cost of the IP filing in your country.
For emergency response and humanitarian agencies once you haul in a load of A2WH devices, within 11 days they will produce their own weight in water and will keep on producing water several years which dramatically reduces the costs associated with delivering water over the medium to long term. A2WH does not require any source water to filter which means it can work in just about any sunny location world wide. With A2WH you can skip many future shipments along with the associated docking and logistics and local people fees. When these costs are factored in A2WH can be very cost effective saving dozens of times it's original cost. In addition the A2WH water is distributed nature and can be installed close to the tents, shacks or homes of the people you service so they are not forced to walk back to a central distribution point every day. This can provide benefits of reducing the spread of disease because you have removed a central assembly points with long lines which are the perfect locations to transfer disease. With A2WH since each system is seaprate, if one point source of water is contaminated due to local neglect it only affects a small number of people and we can easily add ozone treatment that will also provide short term disinfectant features without chemicals
Disclaimer: Production does vary by location. We specifically designed A2WH to produce the most water during the hottest sunniest day of the hottest summer month when water is most needed, the tradeoff is that it produces less water when there is less sun or the sun is weaker. The 1/2 gallon estimate is based on a sunny day June - August in climate similar to Atlanta Georgia, Hawaii or Key West, FL. The system is solar limited so on days with lots of clouds, during the winter or if shaded from direct sun production will be less. We designed for a nighttime humidity above 65% during the coldest part of the night. The system will continue to work with lower nighttime humidity but the production will drop sharply when humidity drops below 50% during the coldest part of the night. Humidity rises at night as the temperature drops so most locations can provide humidity above 50% at night most of the time. We can modify the system to work with nighttime humidity as low as 20% but it does increase the cost.
The A2WH system produces pure potable water from air using only solar
energy. It operates with a much lower operating cost than other
AWG systems because it does not require large amounts of electricity.
The A2WH system absorbs moisture at night when humidity is relatively high and converts what it absorbed the prior night into liquid water the following day using solar thermal heat. Well over 90% of the energy used in the system is solar heat. A2WH is a new generation of solar powered atmospheric water generator device (AWG) which are also known as water maker devices (WM) and Water Air Extraction Devices (WAED). A2WH is not a fog or dew capture system and uses a completely different process. ">
In A2WH systems all condensing occurs at near ambient and does not require any refrigeration. Air filters are used to filter the air before the absorption which keeps the interior of the system clean.
A small amount of energy is delivered by Photo Voltaic panels which operate a microcomputer control system, sensors, blowers, pumps, etc.
When a cost per gallon range is supplied the high end is qty 1 while the low end is qty 5,000. All costs are basic estimates and are influenced by region and fluctuating materials costs. All orders must be pre-paid and we lock prices in when the payment is received by pre-purchasing the supplies at that time.
To use this to calculate capital investment. Choose a system size such as 5,000 gallon per day system at $0.09 per gallon. Multiply daily production by 365 days per year to find the system will produce approximately of 1,825,000 gallons per year and 36,500,000 gallons during it's useful life. To obtain the capital cost you then multiply 36,500,000 * $0.09 per gallon = $3,285,000 purchase price. You should add local installation costs of about 20% and 7% annual service.
We believe that no child should ever be forced to skip school to walk miles to fetch water and those who are forced to do so are handicapped in their ability to grow, thrive and contribute for the rest of their lives. We believe that no woman should be forced to spend her hours walking to fetch safe water because all humans can make a unique and special contribution world but not when they are spending their lives to simply fetch water or gathering fuel to boil water. We invented A2WH to solve this problem by delivering water directly from the air using only renewable energy because that was the best way we could find to ensure those people continued to reliably recieve the water they need in-spite of drought and missing or broken infrastructure.
