Researchers Develop Solar Energy Water Desalination Process

A team of researchers from Australia and China has developed a way to desalinate and purify salty or brackish water into potable drinking water using solar energy, a process that could provide hope for developing areas without reliable or abundant electricity. The World Health Organization says about 2 billion people worldwide do not have access to water that is safe to drink. Contaminated water can lead to cholera, dysentery, typhoid and a host of other diseases. And the WHO says that situation will only worsen in the next five years. In a study published Monday in the science journal Nature Sustainability, the scientists said they had created a sustainable solution that relies on sunlight to jump-start the filtration process instead of heat or electricity.
