Indian Institute of Technology (IIT) Guwahati Researchers have developed materials that can produce energy from water, on a small scale.According to IIT-Guwahati these new ways of producing energy can be employed in household environments to support the concept of decentralization of energy sources. The researchers of IIT Guwahati employed the nanoscale phenomenon called “Electrokinetic streaming potential” to harvest energy from flowing water on the small length scale like water flowing through household water taps. The generation of energy from water in various forms – river flow, ocean tides, stagnant water, and even raindrops, is now known as “blue energy”. Dipping the two filter papers into water produces potential up to 570 millivolt, which was stable for a few days (80 hours). Water stored in buckets and water flowing from taps can potentially be used to produce energy if such nanogenerators can be developed further.
