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,

Making Water from Air ?





David and his wife Laura Doss-Hertz just won 



XPrize for Water Abundance








 


=====================







Highlights :


They prevailed by developing a system that uses shipping containers, wood chips and other detritus to produce as much as 528 gallons ( 2,000 liters ) of water a day at a cost of no more than 2 cents a quart (1 liter).


They settled on creating little rainstorms inside shipping containers by heating up wood chips to produce the temperature and humidity needed to draw water from the air and the wood itself.


And if you don’t have wood chips to heat them with, coconut husks, rice, walnut shells, grass clippings or just about any other such waste product will do just fine


Certainly in regions where you have a lot of  biomass  this is going to be a very simple technology to deploy,” said Matthew Stuber, a professor of chemical and biomolecular engineering at the University of Connecticut and expert on water systems who was one of the panel’s judges.

He called their water-making machine a “really cool” merging of rather simple technologies that can be used to quickly deliver water to regions hit by natural disasters, stricken by drought or even rural areas with a shortage of clean water.


Now , every year, Punjab and Haryana are blamed for rising air pollution and smog caused by crop residue burning by growers.

The two states annually generate 220 lakh tonne and 65 lakh tonne of paddy stubble, respectively.




I urge PM – Science, Technology and Innovation Advisory Council , to call up David Hertz and get the detailed drawings / process from him for manufacture of these devices in India under a Licensing Agreement



And I urge Captain Amrinder Singhji to get these devices manufactured by very clever craftsmen of Punjab and give these away ( FREE of course ) to each and every GRAM PANCHAYAT



If done , Punjab farmers will get clean drinking water in return for their stubble !



And in the process, Delhi will get spared of the smog !



Shri Arvind Kejriwalji may consider contributing to this project !

Thank You , Captain Amrinder Singhji
