New water vapor condenser takes cues from darkling beetle

Posted by in category: energy

Access to clean water is a huge issue across the globe. Even in areas with water resources, a lack of infrastructure or reliable energy means purifying that water is sometimes extremely difficult.

That’s why a vapor designed by University at Buffalo and University of Wisconsin-Madison engineers could be revolutionary. Unlike other radiative vapor condensers which can only operate at night, the new design works in direct sunlight and requires no energy input.

“We have worked on solar-driven water evaporation technologies in the past years,” says Qiaoqiang Gan, Ph.D., professor of electrical engineering at UB and a leading corresponding author. “We are now addressing the second half of the water cycle, condensation.”
