Analysis found that Roughly 1 billion people in the world have no access to safe drinking water, and the worst case is that 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?
