Nanotech tea bag creates safe drinking water instantly, for less than a penny

from io9:

A new “tea bag” uses nano-fibers to suck contaminants and bacteria out of water, providing a desperately-needed, cheap solution for the billions of people without clean drinking water.

Researchers at South Africa’s Stellenbosch University made the device from the same material used for the bags of the country’s popular rooibos tea. Inside the sachets are two tiny destroyers of all things unsafe: ultra-thin nanoscale fibers, which filter harmful contaminants, and bacteria-killing grains of carbon.
