Earth's water composition reveals that only 3 percent is freshwater, with a mere 0.3 percent accessible for consumption. This limited resource is threatened by contamination, urbanization, and climate change, endangering the health of over 2 billion people reliant on unsafe drinking water. Innovative solutions, such as solar-powered desalination, are essential. Researcher Xi Shen developed an efficient aerogel that enhances evaporation processes, making desalination more viable for larger populations and addressing current performance limitations in existing systems.
Xi Shen and his team developed an aerogel that improves the desalination process, achieving higher efficiency in freshwater generation compared to previous methods. The aerogel enhances evaporation through better heat localization and improved transportation of water and vapor, addressing challenges faced by traditional desalination systems.
The scarcity of freshwater is alarming, with only 3 percent of the Earth's water available as fresh, and 0.3 percent being accessible for human consumption. Contaminated water sources affect over 2 billion people, risking outbreaks of diseases like cholera and typhoid.
