3. MAIN TECHNOLOGIES
Air to Water – AW – 7500
A wind driven product that produces clean water from air,
with no grid connection, outside power or chemicals. The
airflow over the cold side of the heat exchanger condenses
the humidity in the air, just as in a dehumidifier, to produce
up to 7,500 liters per day.
Water to Water – WW – 90K
A wind driven product that produces clean water from salty,
brackish or polluted water, with no power or chemicals
required. The unit provides up to 90,000 liters per day
under favorable conditions.

4. Regions with suitable conditions
 We have identified those global regions which have the best mix of wind and temperature conditions.
Water to water
Water to water
& Air to water
Water to water
This technology is most suitable when used in areas with air temperatures, warm and humid climates, such as
the Middle East, parts of South America, Africa, Australia, and Southeast Asia, including Indonesia.
OSI Steel Pvt Ltd

5. MAIN PRINCIPALS
This Product does not require an outside power source as it has
an independent energy generation through the windmill
rotor. The system will convert energy from the wind into
mechanical energy which instead of converting it into electrical
energy as in most cases is converted into thermal energy.
The air to water windmill uses atmospheric humidity as its
water source, and wind as its energy source. Now the question
is - Will the atmosphere run out of humidity? Not likely!
Engineering estimates made by Rainmaker suggest that there
is roughly a constant 14,000 Km³ of water in the air in the
form of water vapor. The evapo-transpiration process in the
hydrologic cycle replenishes the water vapor every 9 days. This
makes a water supply source that is limited only by the
arithmetic of possibilities, and unlimited by practical
considerations

7. AIR TO WATER – AW- 7500
Operating Principals
 The Rainmaker turbine forces air through a heat
exchanger where the air is cooled and condensation
takes place. When the temperature falls below its
dew-point, water droplets will form and are collected
in a water storage compartment. Warm ambient air,
in particular, may contain large amounts of water.
 Lowering the temperature of air requires relatively
little energy. By doing so, large volumes of water
become available by condensation and can be utilized
as drinking or irrigation water.
 The system is highly efficient in converting wind
energy to thermal power, which in turn, feeds the
water production unit attached to the tower.

11. WATER TO WATER – WW – 90K
A wind driven product that produces clean water from salty, brackish or polluted water, with no
power or chemicals required. The unit provides up to 90,000 liters per day under favorable
conditions. The output will also depend on the size and input capacity of the chosen location and
installation
In many regions where briny or brackish water is found, this type of wind turbine will provide an
answer to the problem. Beside the ability to make clean drinking water, its use of sustainable
energy ensures that the environment will not become more overburdened and, important for the
user, that energy costs will be independent of the supply-and-demand whims of energy markets.
OSI Steel Pvt Ltd

12. WATER TO WATER – WW – 90K
 The water production unit is distinct from the Air to water solution, even though it utilizes the
same proprietary direct driven compressor system.
 The Water to Water (WW) Solution is even more energy efficient than the Air to Water Solution,
utilizing a thermal process similar to Multi-Stage Flash (MSF) and Multiple-Effect Distillation
(MED), but in a unique hybrid process that utilizes a membrane as well. The heat is used in a
membrane distillation process
 Features
 Stand-alone system
 No external energy sources needed
 Clean water production as competitive rates
 Producing clean, fresh drinking water from brackish or sea water
 Capacity range: 95,000L scalable to 200,000L (annual average per day)
 Limited maintenance due to membrane technology
 Operational in short time: 90-120 days
 Wind speed 3 – 18 m/s or 6.7 – 40 miles per hour
 Appropriate for regions with access to water
OSI Steel Pvt Ltd

13. WATER TO WATER – WW – 90K
Operating Principals
 Here, water is used as a basis raw material instead of air. The total output of the
turbine is much bigger, resulting in a lower price per cubic metre of potable water.
 Heat is produced from the power unit by the use of a heat pump. This heat is used in
a “flash evaporation” process.
 Vapour produced from heating the water then passes through a porous hydrophobic
(water repelling) membrane.
 The WW unit’s membrane only allows water vapour to diffuse through, unlike
Reverse Osmosis where water containing dissolved salts and/or other solids pass
through the membrane. The pores in the membrane are also larger than the pores in
Reverse Osmosis membranes and there is less pressure and energy required for the
vapour to pass through the membrane.
 The driving force of this technology is actually the partial pressure difference
between each side of the membrane pores. The efficiency of the WW Membrane
Distillation system makes it possible to desalinate large quantities of water with very
little energy.
 Membrane Distillation is a relatively new method of desalination and renewable
energy is well suited to serve as the input source of energy. Recent developments in
membrane technology have created significant interest in marrying renewable
energy with Membrane Distillation.

14. SOME FACTS
 Differences in temperature and humidity in each of these areas affect the amount of water that
will be generated by this technology. This is related to the amount of water contained in the
air. For example,
- air with a temperature of 20 ° C and 50% RH containing 7.3 grams of water per 1
kilogram of air
- air with a temperature of 45 ° C and 15% RH contains almost 10.42 grams of water per
1 kilogram of air

16. PILOT PROJECTS
 In September 2013, A 'water-from-air' technology pilot project was
successful installed at a site in Um Al Himam, Kuwait. The chief objective
of the pilot installation is to validate the technology in the "difficult
conditions of the Kuwaiti climate".
 The facility has already successfully produced water out of air at the site -
and the Kuwaiti Environmental Protection Agency (KEPA) intends to use it
to supply its 'green wall' project, an ongoing government-backed scheme,
which aims to plant 315,000 trees along the borders of Kuwait along a
420 km stretch within the next ten years.
 In addition to the Kuwaiti installation, the company also operates a pilot
plant at Leeuwarden in the Netherlands. Both facilities have successfully
produced water out of air. Currently discussions on expanding the
capacity of the KEPA project are being undertaken
 The fact that the two facilities are located at sites with 'very dissimilar'
topographical and climatic conditions, serves as a validation of the
technology - and suggests that it is viable "for all locations with conditions
that lie between these two extremes".

18. SUITABLITY OF THE TECHNOLOGY
 The technology is especially suitable for remote locations - mainly because it does
not need to be connected to an existing energy grid or water infrastructure, meaning
it can be constructed "in the exact location where water is needed the most". This
also provides an added advantage because it reduces the need for the transportation
of water, which is "very costly and environmentally unfriendly".
 Not only does it now mean that water can be produced at relatively cheap levels
anywhere across the world, it also means that the need for long distance,
progressively aging, distribution networks is reduced. With RainMaker water can be
produced locally, even if there is not a reservoir or groundwater source nearby
 Another intriguing possibility is the idea of installing the AW75 technology in wind
farms, possibly in combination with existing wind turbines, to create "a completely
self-sufficient area in terms of energy and water
 Perhaps less obvious are the island community opportunities, in particular in tourist
areas, where seasonally fluctuating water demands mean that large quantities of
potable water often need to be shipped in from mainland sources or produced on-
island using very expensive techniques.
 Rainmaker technology can be installed in various places and for various purposes
such as drinking water, agriculture, industry, Beverage industry, fire fighting,
military, mining sector etc.
OSI Steel Pvt Ltd

19. MARKET APPLICATION
 Aid / Disasters
 Military
 Agriculture
No water, no agriculture. It is as simple as that! But usable water is not readily
available everywhere. We are digging deeper and deeper for wells, we are
transporting water over hundreds of miles and we are using expensive reverse
osmosis technologies to be certain of a steady water stream for agricultural
purposes. Rainmaker offers solutions to clean brackish, salty or contaminated water
in a sustainable way. The natural elements provide us with the energy to purify the
water for agricultural use. We don’t even use chemicals. We purify water that
contains up to 300.000 ppm of saline in one treatment.
 Drought
Unfortunately many parts of India is facing severe drought situations, mainly
Maharashtra, Bundelkand, Karnataka etc. transporting water from one place to
another is just a temporary solution and an expensive one. The heavy expenditure
does not provide any long term solution, Whereas our technology provides LONG
TERM solution.
Building dams, installing water pipelines are not only time consuming but also
require heavy capital expenditure . No doubt such activities are essential and must
go on. Our technology will complement these efforts and investments
OSI Steel Pvt Ltd

20. WINDS OF CHANGE
WINDS OF CHANGE - WATER FROM AIR A COMPLEMENTARY SOLUTION
We know that even though we may have the best of such infrastructure,
there will still be a shortage of water, due to bad monsoons , climatic
changes, depleting Glaciers etc. This situation is going from bad to
worse. What is even more cause of concern is that the rivers and dams
are drying up more often now. We have another catch 22 situation –
ground water levels are going down. The situation gets even more
aggravated due to the fact that most of our rivers and water bodies are
highly polluted, so a large portion of water that we have in our eco
system is unavailable to us for our day to day use.
Our technology will play a very small but extremely important role under
such complex situations. It will not only provide immediate solutions to
the tens of millions of Rural Indian citizen, but will also play an important
role for climatic change.
OSI Steel Pvt Ltd

21. WINDS OF CHANGE
Some of the major benefits:
Financial Benefits
1. The capital costs will be far less than the traditional solutions
2. The time to implement the project/s will be far less
3. The energy consumption for day to day operations will be nil
4. It will be much more easy to solve the problem at the
targeted water scarcity area.
Social Benefits
1. People will be able to get clean water without any risk of
contamination, thus improving the health
2. Women & Children will not have to travel long distances to
fetch water, this will save them time and energy, which we
play a significant factor to improve their health
3. As water will be more easily available the rural people can
increase the intake of water which probably they would have
been avoiding due to scarcity
OSI Steel Pvt Ltd

22. WINDS OF CHANGE
Some of the major benefits:
Climatic & Ecological Benefits
1. As less water from the wells & other ground water sources will be consumed,
ground water levels can increase.
2. The water to water technology can be a very viable solution in terms of cost & ease
of implementation. It will help in removing the water contamination from polluted
bodies (by using no energy), thus reducing ground water contamination and also
reduce the discharge of contaminated water into the rivers and other water bodies.
3. Due to this technology the Government, the farmers, the rural people do not have
to be totally dependent on mother nature for rains to keep the rivers flowing, to
have sufficient water in the dams , to irrigate the fields, and the supply of clean
drinking water 365 days a year.
4. As no electricity from the grid will be used no greenhouse gases will be emitted,
thus contributing towards carbon footprint in a very big way. If this technology is
implemented in a large scale, it could have a very large impact on the carbon
footprint.
The Government can fulfill its commitment of providing clean drinking water to the
people of india at a much earlier time frame, with less resources. Besides going for
a pilot plant, a particular water scarcity area – say Latur, or Bundelkhand can be
chosen as pilot project to install several machines to meet the demand of that area.
The success of that can be replicated for the other water scarcity areas on a
mission mode similar to that of Electricity for every Village
It is more relevant now that states are fighting for rights over rivers
OSI Steel Pvt Ltd

23. WINDS OF CHANGE
Some suggestions & ideas:
The technology could also be used as a supplementary source
for water guzzling industries and Commercial establishments.
The water saved in this process can be diverted to main town
& cities for drinking & irrigation purpose. The industries
which could Afford to use this technology are:
1. Power plants
2. Alcohol & beer industries
3. Beverage Industries
4. Paper, Steel & textile
5. Ports, Airports
Another feasible usage could be the open cast mining sector
which have pits 30-40 meters below ground level, and water
collected there is not fit for consumption, like lignite, shale,
clay, coal mines, stone quarries etc.
Most of the STP’s do not work due to lack of electricity which
defeats the very purpose they were meant to solve – treat
industrial waste before it is released into the rivers. Our
technology can be an ideal & reliable solution.
