3.  Fan Blades: From 2-Liter bottles  Generator: 20 small magnets positioned around a metal disk with alternating poles -magnets spin over 12 coils of wire  Blades attached to brass pipe that spins within two ball bearings.

4.  Wind enters through one side of the blades and exits through the other side of the overlapping blades --Two-tiered blade design  Fan blades are attached to a brass rod which spins the magnets over the coils

5.  Magnets are placed around a metal disk and alternate in polarity ◦ This gives an alternating current when passing over the coils ◦ Coils are attached in series (makes voltage additive)

6.  Any variation in orientation of the coils significantly impacted the power created.  We had to add more coils than we intended.  The 2-liter bottles were hard to position in the styrofoam.

7.  Measured voltage=1.75 volts  For the wind produced by the fan:

8.  Our windmill created enough voltage and amperage to light the light bulb.  We had a few minor difficulties, but our original design ultimately worked.
