Clean Drinking Water
Around
the world , every year , millions of people die a premature death by drinking
dirty water , teeming with harmful pollutants / bacteria / germs
This
is especially true of our country where , 6.5 lakh villages do not have a
supply of filtered piped water to their homes
Millions
of people living in these villages depend upon water sources such as open wells
/ bore wells / ponds / rivers , around which village women wash their dirty
cloths / vessels and take baths
Even
the dirty water flowing out of huts / homes, gets absorbed into the soil
surrounding these water sources and further pollutes them !
All
of these water sources are highly polluted and the traditional method of
filtering with a thin cloth is just not enough to remove those pollutants
True
, some germs / bacteria can be killed by boiling the water and then cooling it
before drinking
But
, to do that , one needs to burn wood / cow dung cakes , which cause air
pollution and deforestation !
And
, of course , villagers cannot afford expensive methods such as :
* Reverse
Osmosis
* Water
Heating Stills
* Desalination
Plants
What
they need is some SIMPLE AND CHEAP method , which does
not require ,
* burning
of wood / cow dung cakes
* supply
of electricity
* frequent
replacement of expensive filters
* difficult
maintenance
It
is very heartening that a team of scientists have just come up with such a
method
By draping black, carbon-dipped paper in a triangular
shape and using it to both absorb and vaporize water, they have developed a
method for using
sunlight to generate clean
water with near-perfect efficiency
Read about this at :
I urge Shri Nitin Gadkariji ( Minister
for Water Resources ) to contact these scientists at :
SPEED MATTERS
Our patented carbon nano-material cloth
has the ability to evaporate water at rates of up to 1.4 kg per square
meter per hour
