This project showcases a windmill design by Matt Iannacone, Sammy Akato, and Stephen Zimmerman, utilizing a Kenex box structure, a generator, and a fan. The fan, crafted from balsa wood and tissue paper, operates on a water wheel principle to capture wind energy, transferring kinetic energy to rotating magnets within an insulated wire generator. The project faced challenges like fragile components and efficiency issues, but successfully demonstrated the principles of wind energy conversion. Overall, it emphasizes the importance of teamwork and offers insights into green energy solutions applicable on a larger scale.

Design • Our design consists of a Kenex box structure, a generator, and a fan. • As the fan turns due to wind power the magnets will rotate within the generator producing the voltage needed.
Fan Design • Created out of balsa wood and tissue paper • Water wheel style • Supported by Kenex • Three blades • Extremely light
Generator Design • Insulated wire wrapped around a coke bottle • Wrapped 700 times • Placed and supported in a box structure • Earth magnets run within the coils • Connected to the fan
Mechanical and Electrical Aspects • Wind energy captured by the fan • The more wind the more rotations • Magnets rotate • Magnets create electrical current • Energy loss due to friction, generator resistance, and fan flaws.
Construction Issues • The generator • Difficult to create • Problem with efficiency • The fan • Fragile • Sensitive to moisture • Overall • Project was challenging • Time consuming
Efficiency • Equations • Ptheoretical= ½(ρAV3) – density(air) * surface area(fan) * air velocity • Ptested= VA – volts * amps = watts • (Ptested/ Ptheoretical) * 100 = efficiency • Values • Ptheoretical= ½ * 1.225 * (.11516) * 1.73 = .3465 watts • Ptested= 1.4 * .0035 = .0049 watts • E = (Ptested/ Ptheoretical) * 100 = 14.14% efficiency
Conclusion • Project was successful • Learned basic concepts of electricity and generators • Development of teamwork • Better materials could produce a higher efficiency • Spent $21.29 • This project is relevant because at a large scale windmills are used to produce green electricity for everyday life.
