The Hope Project: Nano Teabags
Safe drinking water is what most people take for granted. In many parts of the world it is much sought after and in some areas, it is almost impossible to find.
Good news is, scientists from South Africa’s Stellenbosch University claim that they have a great solution, inspired by their love of tea.
What they have developed are water filters that are made with ultra-thin nanoscale fibres. These fibres filter out harmful contaminants and bacteria-killing grains of carbon, which are shaped like a teabag.
According to the researchers, each filter can effectively clean up to a litre of even the most heavily polluted water.
These "teabags" can be thrown away once used. And since these nanofibres will disintegrate in liquid form after a few days, it will have no environmental impact.
One of the best things about it is each filter is projected to cost less than half a cent. So aside from being economical, it also very effective. (See a video about the project here.)
A simple, yet elegant solution to a tremendous problem – thanks to hard work and the love of tea!
