this is an extraordinary wind generator. you will require all types of odd materials for
making it. first take a film can and make two through holes. then take two short straws
and push them in these holes with a gap in the middle.then take thin insulated copper
wire used in motor winding and wind almost 600 turns, criss cross. adhere with glue.
take a paper cup and cut out slightly tapered blades from them. this cup has a natural curvature,
so blades would be curved. after you cut the blades, slightly shape them by removing the
triangles and make seven equal blades. make a hole in the middle of the lid and apply
glue on its surface. once it dries partially, stick all the seven blades and this would
make the rotor. finally in the middle press fit a cycle spoke. now this completes the
rotor assembly. take a piece of rubber, stand four sticks and stick a little CD piece in
the middle. then cut the film can so as to make just a short pipe. take the film can
and tie it tightly on the four sticks. you can also glue it in place. now take an LED
and join its two ends to a wire. take a bicycle spoke and fix it in its nut. at the other
end of the spoke put an old refill. now take the rotor assembly and insert the fan with
the spoke in the two bearings with a little rubber piece in the middle. in the end take
a piece of refill and stick it to the lower end of the spoke. so that the refill point
of this whole rotor will rotate. now take two strong magnets and stick them back to
back on the rubber piece. the north will stick to the south. now scrape the two ends of the
insulated copper wire and attach it to the LED. now your wind generator assembly is almost
ready. you just need to place it under a fan. rotor will rotate, magnets will spin, producing
electricity in the coil and the LED will blink and light up. what a delight!!
