Electro-kinetic streaming: To produce energy from flowing or stagnant water

Part of: GS Prelims and GS III- Science & Technology

In News

  • Researchers at the IIT-Guwahati (IIT-G) has developed materials that can produce energy from flowing or stagnant water in households.
  • Electro-kinetic streaming potential: When fluids stream through tiny channels(made up of special semiconducting material) that are charged, they can generate an electrical voltage, which may be harnessed through miniaturised generators.
  • Devices with doped graphene flakes was also fabricated for generating power by dipping it in a bucket of water or any stagnant water source to “complementary charge transfer activities”
  • Graphene is the sheet produced by oxidation followed by reduction of natural graphite flakes.

Value Addition for Prelims – Graphene:

  • Graphene is a form of carbon and a super-strong, ultra-light material discovered in 2004
  • Graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice, each atom bound to its neighbours by chemical bonds. 
  • It enables flexible electronic components, enhances solar cell capacity, and promises to revolutionise batteries.
