2. Team Members  Andrew Wills: Biomedical Engineering  Patrick Slavick: Electrical Engineering  Tyler Kiste: Industrial Engineering  Mike Grigalus: Computer Engineering

3. Design: The Spirit Bomb  Generator constructed from:  plexiglass  PVC  4 block magnets  400ft of copper wire  Frame constructed from:  particle board  L-brackets and screws

4. Design  Propeller constructed from:  8 curved plate tin blades  Blades connected to aluminum axel  Lube to reduce friction  Blades spin about a horizontal axel that spins the magnets directly.  Cost: $21

5. Mechanical Aspects  Wind energy from the fan spins our propeller.  The spinning propeller turns aluminum rod.  Magnets attached to our rod are also spun.  Length and surface area of the blades adds to the torque on the rod

6. Electrical Aspects  Magnets spin within a box that is wrapped in magnet wire.  Spinning magnets create constant changes in the magnetic field.  Changes in magnetic field causes voltage within the wire.  Because our circuit is closed, this voltage begins to flow creating an electrical current thus lighting our bulb.  This process is called Electromagnetic Induction.

7. Design Issues  Choosing the type of propeller to use -wind turbine, two liter bottles, two blade propeller, and finally the 8 bladed, sheet tine prop  Finding copper magnet wire  Properly stripping the wire  Mounting the generator box and assuring sturdiness  Re-attaching magnets to a new rod after the generator had been constructed

8. Conclusions  Windmills are much so much better than roller coasters (at least the construction part)  Simplicity, in this case, was the key to being successful  This wouldn’t have been possible without contributions from each team member
