Roughly 1 billion people [2] in the world have no access to safe drinking water, and contaminated water [3] 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 [4] 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 [6] to filter harmful contaminants, while grains of activated carbon to kill bacteria. Simply put the tea bag in the neck of a water bottle [7] and drink the water through it.

Marelize Botes, a microbiology researcher at South Africa [8]‘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?
