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?"

With regards,

WAITING FOR WATER WARS ?


Deja  Vu  ?

------------


Wikipedia defines “ Déjà vu “ as follows :

Another possible explanation for the phenomenon of déjà vu is the occurrence of "cryptomnesia", which is where information learned is forgotten but nevertheless stored in the brain, and similar occurrences invoke the contained knowledge, leading to a feeling of familiarity because the event or experience being ...



Context :

Following headline in Times of India ( 26 Feb ) :

It’s not yet summer, but parts of Marathwada go dry already

913 medium and minor dams in region have less water storage than last year

138 Tankers Supply Water in 111 Villages



In this , where is that  “ Cryptomnesia  “  ?

Water Water Everywhere ?  Even in Latur  ?


( aka “ How to avoid Water Wars next month ? “ )



·         And without sending from Mumbai to Latur , a “ Water Train “ twice a day ?


·         Absolutely  FREE ? ( free of cost and free of Water-Mafia ! )


·         Without women of Latur , having to walk 5 km in 42* C temperature for one bucket ?


·         All of this is possible if Maharashtra Chief Minister , Shri Devendra Fadnavisji , just picks up phone and dials Prof Omar Yaghi ( University of California , Berkeley / yaghi@berkeley.edu / oyaghi@lbl.gov / Ph : 510-643-5507 )


·         After reading the following report , if he does not , it would deeply distress millions of drought-affected Maharashtrians !





Dear Prof Yaghi :


Congratulations for your invention which deserves better than a Nobel Prize


A billion " Thank You " from a billion people is not enough !


·         Even if you do not get that phone call , in the “ Supreme Court of your Conscience “, treat this appeal as a “ Public Interest Litigation “ and make available to the Citizens of India, your technology / patent / manufacturing drawings / material specifications etc , in order to save thousands of lives !



REPORT :




·         A device that can create water out of thin air in even arid environments has been invented that could make Coleridge’s famous line “Water, water, everywhere, Nor any drop to drink” a thing of the past.


·         Using only the power of the sun and a special material with some extraordinary properties, the device is capable of producing 2.8 litres of water in 12 hours.


·         And it can work in conditions where humidity is as low as 20 per cent.


·         Professor Omar Yaghi, who helped create the prototype water harvester, said: “We wanted to demonstrate that if you are cut off somewhere in the desert, you could survive because of this device.


·         A person needs about a [ 330ml ] can of water per day. That is something one could collect in less than an hour with this system.


·         This is a major breakthrough in the long-standing challenge of harvesting water from the air at low humidity. 


·         “There is no other way to do that right now, except by using extra energy. Your electric dehumidifier at home ‘produces’ very expensive water.”


·         But, as well as saving people stranded in a desert, the harvester could become a major part of everyday life, enabling people to have water without a connection to the public supply or a well.


·         “One vision for the future is to have water off-grid, where you have a device at home running on ambient solar for delivering water that satisfies the needs of a household,” said Professor Yaghi, a chemist at University of California, Berkeley.


·         { My Note Just like the Roof Top Solar Power panels which may, someday eliminate the need for an Electric Power Grid ?  }


·         “To me, that will be made possible because of this experiment. I call it personalised water.”

Dear “ Bottled Water Manufacturers “ of India :


It is time you asked ( ala Ted Levitt in his seminal essay “ Marketing Myopia “ ) :


“ What business are we in ? Are we in the business of “ Bottling Water “ or are we in the business of “ WATER “ ?


Time to “ re-invent “ yourselves is just around the corner !


With “ Edible Water Balls “ replacing plastic bottles ?



Here is what start-up “ Skipping Rocks Labs “ writes on its web site :


Our goal :


   To create a waste-free alternative to plastic bottles / cups / plates / you name it


Our vision :


To become the leading global producer of seaweed-based packaging


Our impact :


    To stop 1 BILLION plastic bottles reaching the ocean every year and to stop 300 million Kg of CO2 from being emitted
