A team of researchers at the Indian Institute of Technology-Guwahati (IIT-G) has developed materials that can produce energy from flowing or stagnant water in households.
About:
The decentralised energy model involving a large number of small generation devices can generate energy in every household and the excess energy thus produced can be evacuated to energy-deficient areas nearby.
The team employed “electro-kinetic streaming potential” to harvest energy from flowing tap water and “contrasting inter-facial activities” entailing different types of semiconducting materials to generate power from stagnant water.
Under it, when fluids stream through tiny channels that are charged, they can generate an electrical voltage, which may be harnessed through miniaturised generators.
The electro-kinetic materials have not been harnessed until now.
