Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

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 :
 qqgan@buffalo.edu  /  youhaili@buffalo. edu

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
