Problem
• Design and build a windmill that will generate electricity
• Attempt to power a light bulb

Windmill Design
• Used simplest design possible• Fan blades attached to axel• Axel runs through generator• Axel turns magnets

Generator Design
• Magnet wire wrapped numerous times around aluminum casing
• Four high-powered magnets attached to axel spin perpendicular to wire wrappings to produce electricity

Problems
• Ran into problems with fan blades having trouble turning the weight of all four magnets
• Had difficulty overcoming the friction of the fan blades on the wood
• Had trouble finding casing to wrap wire closer to magnet

Conclusion
• Thought final design was both practical and simple to construct
• Very cost-effective• In retrospect, would have created a more
powerful generator• Very happy with finished project
