Harvest Water from Air using Solar
Energy
(AWG) Atmospheric Water Generator
Tentative price $15,000 Only
shipped to USA. Custom built in other sizes.
- This unit provides
safe water when there is no electricity, no fuel and no source
water.
- It is reliable during
the worst drought when there is no rain.
- It will continue
to deliver water when municipal supplies are disrupted.
- It even works when the air is too dry to
form natural dew.
Extracting water from air has been done for centuries. Every time you see water condensing on the outside of a cold drink or
frost on your windshield you have seen water extracted from the
air. Our units scale this process to produce high
purity water consistently and cost effectively across a wide range of
conditions.
Unlike dew collection system
this unit works sell in hot climates with
strong sun and high winds.

Compared to electrical AWG units.
Common dehumidifiers and air conditioners have been extracting
water from air for decades but they consume large amounts of
electricity in many cases over 3,000 watts per gallon of water
produced. Their electricity consumption makes them infeasible
for remote locations where grid electricity is unavailable. The
electricity consumed can increase their operating costs and makes them
expensive to operate even when grid electricity is available.
Our unit operates from Solar energy. It does not require any grid
electricity. It absorbs the water from the air and it can
work in climates with humidity as low as 30%. Our
unit does not use any refrigerants and can reduce carbon emissions by
over 5 pounds of carbon per gallon of water produced when compared to
electric grid powered AWG units.
Ideal for remote locations:
This technology delivers water in
remote locations where the cost of obtaining water in other ways is
high. It is particularly effective for locations where
ground water is either unavailable or unsafe for human
consumption. It is also great for locations where
water must be hauled in over rough terrain.
Construction sites and remote cabins
It offers a unique advantage for remote
construction sites, yurts and other remote locations due to it's weight
ratio advantages. A single 6 gallon per day system
weights less than 500 pounds. It will produce about
50 pounds of water per day. That means that if left installed for
1 month it will produce 3 times it's own weight in water.
If left in place for 1 year it will produce 36 times it's weight in
water. This weight advantage rapidly pays for itself
especially when water must be hauled over long distances, over
rough terrain or air lifted in.
Compared to desalination:
This technology offers several unique
advantage over desalination:
- It is immune to industrial chemical spills that could clog or
destroy membranes
- It does not produce any waste brine stream which makes it easier
to deploy with fewer environmental risks.
- It does not require any external power sources other than solar
energy
- It does not require any source water.
- No Source water and no Brine disposal makes it easy to deploy
with less permitting.
Islands
This technology can deliver water using
solar and wind energy which are abundant on most islands. It can
be deployed locally close to the point of consumption and it is easy to
maintain with untrained resources. It requires no source
water, is highly resistant to contamination and has no
brine disposal requirements.
- Many Islands have water shortages some of which are getting worse.
- Many islands experience salt contamination of their wells.
- Many islands have high cost and unreliable electricity.
- Many islands have difficulty with high tech pumps and membranes
which must be delivered from the mainland.
- Many islands have limited infrastructure to deliver water to
remote villages.
- Islands are becoming increasingly concerned about coastal water
quality which requires more expensive brine disposal and permitting for
desalination.
Military use:
This system allows production of water
where it is needed without any source water:
- Removing source water from the supply chain makes it more
resistant to attack. It is pretty easy to shut down
desalt facilities with a few barrels of oil or many other
chemicals dumped in upstream.
- It allows water to be produced close to the point of consumption
reduces cost and risk of delivery.
- It removes the need to haul water long distances to the
battlefield which reduces logistical burdens
- It reduces risk to those delivering the water to the point of
consumption.
- Shorter pipelines provide less opportunity for contaminants to be
added.
- Can be set up so the system provides easy erect rooftops in semi
permanent installations and keeps structures much cooler while
providing daytime ventilation of the tents.
- Can be adapted to be powered from a wide range of fuels if solar
energy is not available.
Rated for days with 8 hours or more full sun.
Cooler days or those with lower humidity will reduce production.
- Plan on 2.3 square meters per 1/2 gallon per day.
- Solar Thermal Air to Water AWG Atmospheric Water Generator
- Includes necessary solar collectors
- Requires full solar exposure 8 hour sun day.
- Estimated life 10 years with most components well suited to 20
year life.
- 1 year limited warranty. Factory depot service.
- Technology can scale into the millions of
gallons per day.
- Wind Boost optional can double production in areas with average
winds over 5MPH.
- Recommended for ground or stilt installation.
- Not recommended for rooftop installation unless roofs specially
braced to withstand weight.
- Storage tank and ozone trickle not included.
- Options available for units that work in humidities as low as 20%
RH. (Higher cost and weight).
- Options to allow ground based pre-chilling of air to increase
production rates in very dry climates.
Superior return on investment.
If you installed a large enough solar
array to power an electric based
AWG unit you could easily invest over $26,000 and still could not
produce as much water in the drier climates. The electric unit
and PV
(Photo Voltaic) array would require much more space and more
maintenance. If you tried to operate a gasoline or diesel
generator to
provide the electricity this cost could rise to $30,000 or higher if
the fuel must be imported.
If you purchased bottled water at a rate of $1.34 per gallon you
would
spend over $29,000 during a 10 year life and that doesn't include
the increasing risk of contamination in bottled water, the cost
of
delivering the water or the hassle of getting the bottles exchanged.
