GUWAHATI, Oct. 14 -- Researchers from the Indian Institute of Technology Guwahati (IIT Guwahati) led by Prof. Tamal Banerjee, Department of Chemical Engineering, IIT Guwahati, have successfully produced a novel heat transfer fluid based on nanofluids, which is capable of efficiently transferring heat generated using solar power to desalination systems. This advancement promises a practical solution for producing potable water from seawater, addressing the pressing issue of global water scarcity.

With the world facing a severe water shortage that outpaces population growth, the demand for desalination, a process that extracts freshwater from saltwater, has become critical. However, conventional desalination methods use heat generated by b...
