CSIR-NPL Develops Ferrofluid based Portable Power Generator

CSIR-National Physical Laboratory (CSIR-NPL), New Delhi, has developed a technology called “Ferrofluid based portable power generator”. The green technology is portable, easy to install and can be used for generation of electrical energy in a rural area or seaside. The technology requires low wind power and low maintenance.

Ferrofluid-based power generator is an energy conversion device which converts the wind energy into electrical energy. The concept of generation of electricity is based on Faraday’s principle of Electromagnetic Induction. The incoming air rotates the fan blade, which further rotates the magnets which are connected via shaft. Beneath the magnets, coils are placed. Magnets are dipped in ferrofluid thereby forming Ferrofluid bearing which assists the relative motion between magnets and coil. Coils and ferrofluid bearing are separated by a thin non-porous sheet.
