Will Terry Dankovich’s “Drinkable Book” finally solve the reliability problem of safe drinking water supply for the world’s poorest citizens?

By last count, as many as 358-million people in sub-Saharan
Africa do not have a reliable access to safe clean drinking water. The good
news is researchers have just come up with a book on water safety whose very
pages can be used to filter water to make it safe to drink. Results of the
trials done in 25 contaminated water sites in South Africa, Ghana, Kenya, Haiti
and Bangladesh showed that the said book, which contains tiny particles of copper
and silver, could eliminate over 99-percent of disease-causing bacteria as
stated in the results of the project unveiled at the American Chemical Society’s
national meeting that began back in August 16, 2015.
Teri Dankovich, from Carnegie Mellon in Pittsburgh, who has
been leading the research on what she calls “The Drinkable Book”, said in one
trial that they tested a ditch contaminated with sewage that contained millions
of disease-causing bacteria. Dankovich said: “even if highly contaminated water
sources like the one we tested, we can achieve 99.9-percent purity with our
silver-and-copper nanoparticle paper, bringing bacteria levels down comparable
to those found in United States’ tap water”.
Each paper of the pages in the Drinkable Book is embedded
with silver and copper nanoparticles. The pages contain instructions in English
and the local language the book is destined to. Water is poured and filtered
through the pages themselves. One page can purify up to 100 liters – about 26
gallons – of water and one book can supply one person’s drinking water needs
for about 4 years, the researchers said. The researchers currently make the
books themselves – but are now looking to ramp up production and send the books
to local communities.

When the instructions are actually printed on the device or apparatus to be used, Teri Dankovich's "Drinkable Book" is pretty much idiot-proof to use.
