WIND ENERGY PROJECT

Project Aim
To demonstrate with a simple model that wind is not only used for cooling but can also
be used to light the lamps in our homes or streets. With this project, we aim to generate
electricity without harming nature.

What Am I Doing in This Project?
I will connect a small pinwheel mechanism that I built myself to a motor. When wind
blows from outside (or when we blow air using a hair dryer), the pinwheel will spin.
Through this motion, we will generate electricity and light up a small LED lamp. At the
same time, we will produce the electricity needed to illuminate our model, which
includes houses and street lamps.

Materials Used
We will use one empty soda can to make the blades of the windmill. A DC motor (either
one 24V motor or preferably two 12V motors). A sufficient number of small LED lights
for the model (they may be in different colours). Thin wires to connect the motor and the
lamps. Enough cardboard to build the model of the living area. Other necessary tools and
materials needed for cutting, gluing, and painting.

How Is It Made? (Process)
Build the Tower: First, we glue the paper roll onto a sturdy cardboard base. This will be
the tower of our windmill.
Place the Motor: We firmly attach the small motor to the top of the tower.
Attach the Blades: We fix the blades made from the soda can to the motor shaft. (They
should rotate easily when wind blows!)
Connect the Light: Using thin wires, we connect the motor to the lamps in the model.
Test Time: We blow air onto the blades using a fan or a hair dryer. When the blades start
spinning quickly, the lamp will light up.

Conclusion:
What Did We Learn?
We observed that wind has kinetic energy.
We understood that this motion can be converted into electrical energy with the help of a
motor.
We experienced lighting a lamp without using batteries, only by using air (wind).
