South Africa's newest water purification system uses nanotech inside a common tea bag. Provide people cheap access to clean water and you could save billions of lives. South Africa may use tea bags to do just that. Researchers at Stellenbosch University’s Water Institute have developed a new water filtration system that uses activated carbon and nanofibers to quickly filter out pathogens.More than one billion people – one sixth of the world’s population - are without access to safe water supply. At any given moment, about half of the world's poor are suffering from waterborne diseases, of which over 6,000 – mainly children – die each day by consuming unsafe drinking water. The world’s most prolific killer though is diarrhoeal disease from bacteria like typhoid, cholera, e. coli, salmonella and many others. Safe water interventions have vast potential to transform the lives of millions, especially in crucial areas such as poverty eradication, environmental upgradation, quality of life, child development and gender equality.
