Transcript of Windmill Power
Windmill PowerBy : Matt Iannacone Sammy Akato Stephen Zimmerman
1DesignOur 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.
2Fan DesignCreated out of balsa wood and tissue paperWater wheel styleSupported by KenexThree bladesExtremely light
3Generator DesignInsulated wire wrapped around a coke bottleWrapped 700 timesPlaced and supported in a box structureEarth magnets run within the coilsConnected to the fan
4Mechanical and Electrical AspectsWind energy captured by the fanThe more wind the more rotationsMagnets rotateMagnets create electrical currentEnergy loss due to friction, generator resistance, and fan flaws.5Construction IssuesThe generatorDifficult to createProblem with efficiencyThe fanFragileSensitive to moistureOverallProject was challengingTime consuming
6EfficiencyEquationsPtheoretical = (AV3) density(air) * surface area(fan) * air velocityPtested = VA volts * amps = watts(Ptested / Ptheoretical) * 100 = efficiencyValuesPtheoretical = * 1.225 * (.11516) * 1.73 = .3465 wattsPtested = 1.4 * .0035 = .0049 wattsE = (Ptested / Ptheoretical) * 100 = 14.14% efficiency7ConclusionProject was successfulLearned basic concepts of electricity and generatorsDevelopment of teamworkBetter materials could produce a higher efficiencySpent $21.29This project is relevant because at a large scale windmills are used to produce green electricity for everyday life.
