A $16 device could provide a family of five with clean water for an entire year
About 780 million people—a tenth of the world’s population—do not have access to clean drinking water. Water laced with contaminants such as bacteria, viruses, lead and arsenic claims millions of lives each year. But an inexpensive device that effectively clears such contaminants from water may help solve this problem.
Thalappil Pradeep and his colleagues at the Indian Institute of Technology Madras developed a $16 nanoparticle water filtration system that promises potable water for even the poorest communities in India and, in the future, for those in other countries sharing the same plight. Although cheap filtration systems have been developed previously, this is the first one to combine microbe-killing capacity with the ability to remove chemical contaminants such as lead and arsenic. Because the filters for microbes and chemicals are separate components, the system can be customized to rid water of microbial contaminants, chemical contaminants or both, depending on the user’s needs...

This is why I like Indians...
Sounds good. Hope they get it on the market soon. I have a well, and filters that fit on the faucet. We also keep several cases of bottled water on hand, and each sink has some water in soda bottles for hand washing etc.
I keep a bunch of those personal hygiene packets of wipes that they use in hospitals on hand to use in case there’s a need to conserve water and limit showers. Then there’s the hot water heater water. Then there’s the rainwater collected.
When Hubby gets the swimming pool set up and diverts the rain water to it, we’ll have about 4,000 gallons in that all by itself.
Have several filters, but it wouldn’t hurt to get more.
“I’ll add iodine to the list for extra safety.”
A few drops of potassium iodide (SSKI) to a glass of water renders it safe.
“...it wouldn’t be a bad idea to stock up with some of these...”
Barter items after the SHTF...
