Technology to tap energy from waterDate: 31 December 2019 Tags: Energy
A team of researchers at the Indian Institute of Technology-Guwahati has developed materials that can produce energy from flowing or stagnant water in households.
The decentralised energy model involves a large number of small generation devices that 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” employing different types of semiconducting materials to generate power from stagnant water.
When fluids stream through tiny channels that are charged, they can generate an electrical voltage, which may be harnessed through miniaturised generators.
The team also fabricated devices with doped graphene flakes for generating power by dipping in a bucket of water or any stagnant water source to “complementary charge transfer activities”.
Water stored in buckets and water flowing from taps can potentially be used to produce energy if such nano-generators can be developed further.
