New nanotechnology to produce sustainable, clean water for developing nations

The video addresses the global challenge of providing clean drinking water to over three-quarters of a billion people. Chemist Ben Chow and his team at Stonybrook University are developing cost-effective nanometer-scale water filters. These filters use nanofibers produced through electrospinning and aim to reduce costs further by utilizing biomass from local resources. The goal is to make clean water accessible to the poorest populations, emphasizing that pure drinking water is a basic human right.

What is the main challenge highlighted in the introduction regarding clean water?

• The global scarcity of clean drinking water
