Over 2.8 billion people worldwide suffer from not having the resources to clean drinking water.
A small device is built to assist this problem. Developed by researchers at the Department of Energy at Stanford University, the device works with solar energy and purifies the water by bacteria present in it.
The device the team has built is very small size and consists of copper material and a kind of photovoltaic material called molybdenum disulfide.
When the material is heated by sunlight, its internal structures to deliver hydrogen peroxide and other types of chemicals that are able to rapidly destroy harmful bacteria occurring in water.
Although their experiment failed to kill 99.999% of bacteria in 20 minutes, the researchers say that the device needs to be improved further so that it can be used in large quantities of water.
