Electro-kinetic streaming: To produce energy from flowing or stagnant water
Part of: GS Prelims and GS III- Science & Technology
- 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.
