National Physical Laboratories has developed a portable power genertor that is powered by wind. It converts wind energy into electrical energy.
The concept of generation of electricity is based on the 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.
The advantages of the system are many. First, it is clean power. More importantly, it does not require high wind speeds. The conversion efficiency is high, maintenance low. A pure sine wave is obtained. It is portable and easy to instal.
