2. Team & Device

3. Introduction
Our task was to design and build a windmill that will generate enough electricity to power a small LED.
The windmill was required to be original and built from readily available materials.

4. Generator
Our generator is composed of two disc-shaped magnets which rotate inside of a short pipe wrapped in magnetic wire.
When turned by the fan, the rotations from the magnets produce a small electric current which then powers the small LED light attached to the ends of the wire

5. Efficiency The power in the wind can be found by P= .5 x rho x A x V2
The estimated power in the wind is
.0549 W

6. Budget All Thread - $ 1.40 Steel Sleeve - $ 1.50 Washers - $ 1.60
Nuts - $ 2.40
Magnets - $ 4.00
Spool of Wire - $ 2.75
2.5” PVC Pipe - $ 3.00
Glue - $ 1.00
Red L.E.D. - $ 0.65
Wood - FREE

7. Conclusion
Our main problem was finding a fan that turned the generator without being too heavy.
If we were to do it again we would use a different design to funnel the air to the fan.
