Screen Shot 2015-08-28 at 5.47.38 PMHere’s news of an eco-book that shares info about clean drinking water, so the reader can use the actual pages as high-tech filters that will remove 99% of bacteria from the filtered water. It’s part of a new bactericidal silver nanoparticle paper. Perhaps someday it can bring clean water to the 663 million people who don’t have access to it. Here’s more from the official website:

The Drinkable Book™ is both a water filter and an instruction manual for how and why to clean drinking water. This filter is patent pending technology (US Serial No 62/153,395), and works to produce clean drinking water by pouring dirty water through a thick, sturdy sheet of paper embedded with silver nanoparticles (a.k.a. pAge drinking paper), which are lethal for microbes. This paper was created and shown to be highly antibacterial during Theresa’s Ph.D. at McGill University. Additionally, these filters meet US EPA guidelines for bacteria removal to produce safe drinking water. The filters can last a couple of weeks, even up to a month, so the entire books could provide the tools to filter clean water for about a year. While at University of Virginia for her postdoc, Theresa and a team of students tested these filter papers with water sources in South Africa at the for the next step in developing The Drinkable Book™ for use in the real world. With WATERisLIFE, the filter papers have been successfully field trialed in Ghana, Haiti, and Kenya. Hopefully soon, pAge water filters will supply cheap clean drinking water for many, many people in the developing world.
