A vertical axis wind mill is designed, fabricated
and tested to verify its suitability for low end power
generation applicable for low voltage DC powered electronic
equipment like mobile phones, smart phones, tablets and
battery banks. Low cost material and easily available
materials conforming to standards were used for the purpose
to keep the overall cost minimal. The purpose of the wind mill
is to meet the power requirements during natural disasters
like earth quakes, cyclones and floods when the power supply
from the grid is interrupted. It was observed that DC power of
90 mA at 0.2 volts could be generated with the wind mill. Use
of lighter materials and better design could yield higher
electrical parameters.
