As per one estimate, there is 50,000 cubic kilometers
of water contained in the atmosphere
And all of this, is safe / potable / drinking water ( -
we have all heard of Chatak bird drinking rain drops even before they fall to the ground ! )
This “ water in air “ is everywhere – even in arid , semi-arid and desert areas
And , unlike water tables going deeper and deeper on
the earth , “ water in air “ stays accessible , all the time – and right above
our heads
Only problem is :
Finding a cheap method to extract it , without use of
electric power ( as in sea water desalination )
Around the world, several scientists are working on
this problem – with varying success
Latest to succeed is :
Guihua Yu of the University of Texas
His research is reported at
Here is how Indian Express reports :
Highlights :
# The technology relies on hydrogels, gel-polymer hybrid
materials designed to be “super
sponges” that can retain large amounts of
water
# This
new system could tap into those reserves and potentially lead to small,
inexpensive
and portable filtration Systems
# “We have developed a completely passive system where all you
need to do is leave the
hydrogel outside and it will collect water,”
said Fei Zhao, a postdoctoral researcher on
Yu’s team.
“The collected water will remain stored in
the hydrogel until you expose it to sunlight.
After about five minutes under natural
sunlight, the water releases,” Zhao said in a
statement.
# “ The new material is designed to both harvest moisture from
the air and produce clean
water under sunlight, avoiding intensive
energy consumption,” said Yu, an associate
professor of materials science and mechanical engineering.
# Technology requires only solar power, is
compact and can still produce enough water to
meet the daily needs of an average household,
researchers said

Some few months back, PM Shri
Modiji has constitutes a “ Science , Technology and
Innovation Advisory Committee [ PM - STIAC ] “
PM-STIAC has identified following
missions :
Natural Language Translation...
Quantum Frontier...
Artificial Intelligence...
National Biodiversity Mission...
Electric Vehicles

Considering
that most metro cities of India are likely to run out of water in next 2 / 3
years and rural women all over India have to walk 10 Km, in 40*C temperature
under blazing sun for a bucket of brackish water , I urge PM –
STIAC to add
“ WATER HARVESTING from AIR
“
- as a
mission , with highest priority
In this
regards, Committee members may want to go through following blogs where I have
listed similar water harvesting innovations :

Making Water from Air ? ………………………………………………………………………. 26 Oct 2018
===============================================================
I urge NITI Aayog to launch an initiative called SAVE ( - along the lines of FAME for EVs ), under
following broad categories :
[
A ] Finding / implementing , new sources of water ( Creation )
·
Harvesting water from Air ( - as listed
above )
·
Desalination ( which uses Solar Power and
not electricity )
[
B ] Finding / implementing, methods of water conservation ( including recycling )
·
Interlinking of rivers
·
Digging water ponds in villages
·
Recycling domestic water usage ( like Food
Chain, establishing a Water Chain )
# Drinking
Water ( Municipal supply )
# Washing Water ( Bath / Utensils / Clothes /
Hands ) [ Rain Water harvesting ]
#
Flushing Water ( Recycled washing
water after filtration )
·
Establishing “ water usage quota /
rationing of water “ – per person in household
·
Gradual introduction of “ pre-paid “ smart
water meters which cuts off supply when quota used up
[
C ] Incentivize companies manufacturing devices / equipment for
[A] and [B] above
Eg : MM Industrial Controls , which
manufactures Bio-Digester
This is
just one example . There are hundreds of companies in this field
This
could be in the form of GST waiver / nil Corporate Income Tax for 10 years
[
D ] For urgent completion of the above, consider following
POLICY FRAME- WORK
( as
outlined in : Water Wars ?
……………………. 08 April 2016 )
# At
the level of Central Government
* Make
" Water Conservation / Usage " , a CENTRAL SUBJECT in our
Constitution . Remove it from the list of STATE SUBJECTS
* Declare all existing sources of water ( Rivers and
Lakes ) , as National
Resources belonging to entire Nation and not
to the particular State
where these are located
* Make it Center's responsibility to decide which
State shall use how
much of each of these resource (
allocation / rationing )
* Center will also be responsible for developing of
future resources by
digging lakes & ponds / building
dams / interlinking rivers & lakes etc
Use MNREGA funds for creating such
assets
* Center will not need permission of any State to
implement such projects
* Center will implement " River Interlinking
" Project by 2025 , and for this,
it will not require permission of any
State
As repeatedly lobbied by me , please
find a way to divert BLACK MONEY
to this Infrastructure SPV ( Tax haven
or local - which is 100 times ! )
* Mercilessly , shut down all factories dumping
polluting effluents in rivers
# At the level of State Governments
* Make following mandatory for ALL buildings (
existing or future )
+ Rain water harvesting system ( this
tank to supply toilets / sinks etc )
+ Recycling of water from Kitchen /
Shower / Wash Basins, for use in
toilets , by
installing a simple sand filtering tank in society compounds
+ Installation of water flow
restricting devices in all taps
+ Mechanism which stops water flow when
hands are removed under tap
+ Water Supply Cut of 25 % , round the
year
Do not raise
Water Charges . The higher the charges , more ways will
be found to
evade ( as in case of Personal Income Tax ! )
Water meters
will get tempered or by-passed !

PS ( 15 Aug 2019 ) :

/ contact@jawwadpatel.com
Congratulations , Jawwad for this breakthrough !
I hope Governments ( both Central and States ) take notice of your innovation and , if convinced about its practicality, go all out to support / commercialize your patented device
And , if they do , I am sure, you will not allow monetary gains to come in the way of its mass production and FREE distribution among villages located in semi-arid areas
It was only today morning that PM Shri Modiji spoke ( in his Independence Day speech )to take piped water to 80 % of our population
If implemented , your device can , not only save thousands of crores of rupees but enable implementation within months, instead of years !
On my own , I am forwarding this blog ( addendum ) to all the Cabinet Ministers, hoping that the concerned Minister will contact you immediately
