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 water vapor condenser designed by engineers at UB and the University of Wisconsin-Madison could be revolutionary. Unlike other radiative vapor condensers that 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, UB professor of electrical engineering and a leading corresponding author. We are now addressing the second half of the water cycle, condensation.

New condenser makes water from air, even in hot sun
Access to clean water is a pressing issue for many people around the world. Even in areas with ample water resources, a lack of infrastructure or reliable energy means purifying that water is sometimes extremely difficult.
That’s why a water vapor condenser designed by 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.
“Water sustainability is a global issue,” says Zongfu Yu, an associate professor of electrical and computer engineering at UW-Madison. “You can’t set out to solve the water problem without addressing energy.”

Lately, scientists have been investigating how a passive cooling technique called sky or radiative cooling can be turbo-charged with sun-blocking nanomaterials that remove heat away from the rooftops of buildings.
Although advances have been made, this environmentally friendly technology is not an ordinary thing, because investigators have struggled to increase the cooling capabilities of materials.
A new study, headed by engineers from the University at Buffalo (UB), has made considerable advancement in this field. Published in the
