The Drinkable Book, a book whose pages both educate people about water safety and also function as low-cost water filters. Too good to be true?
The pages of The Drinkable Book are made with silver nanoparticle-coated paper that filters 99.9% of bacteria. Invented by Carnegie Mellon researcher Dr. Theresa Dankovich, the paper costs pennies to produce per page.
Now, this seems like a clear and scalable solution to a pervasive problem that kills 3.4 million people every year. Outstanding technology and work.
