Nanotech Tea Bag Purifies Drinking Water for Less Than a Penny
Posted By Cameron Scott On August 17, 2010 @ 7:05 pm In global development,Water Issues | 7 Comments
Roughly 1 billion people  in the world have no access to safe drinking water, and contaminated water  kills more people worldwide than all forms of violence combined. Seeking to provide a solution to this problem, South African researchers have created a water-purifying nanotech  tea bag that costs half a cent. Portable, instantly effective and with no chance of recontamination, the tea bag sounds like the best idea since sliced bread.
Here’s how the nanotech teabag works: it combines ultra-thin nanoscale fibers  to filter harmful contaminants, while grains of activated carbon to kill bacteria. Simply put the tea bag in the neck of a water bottle  and drink the water through it.
Marelize Botes, a microbiology researcher at South Africa ‘s Stellenbosch University says “The nanofibres will disintegrate in liquids after a few days and will have no environmental impact. The raw materials of the tea-bag filter are not toxic to humans.”
Even at half an American cent, the tea bag may be too expensive for the world’s poorest to afford — but that’s what NGOs are for, right?
