ELECTRO-KINETIC STREAMING POTENTIAL

Dec. 31, 2019

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.
