Scientists has developed a novel solar powered harvesting system that can absorbs moisture from the air and can converts into clean water. This technology is described in the Journal Advanced Materials, could be used in disaster situations. A team of Researchers led by Guihua Yu from the University of Texas, US used hydrogels that is highly water absorbent and can release water upon heating.
“We have developed a completely passive system where all you need to do is leave the hydrogel outside and it will collect water,” said Fei Zhao, Postdoctoral researcher in Yu’s Team.
“The collected water will remain stored in the hydrogel until you expose it to sunlight. After about five minutes under sunglight, the water releases,” Zhao also said in statement.
Prototype test of this technology shows that the daily water production of upto 50 litres per kilogram of hydrogels.
