Windmill PowerBy : Matt Iannacone

DesignOur 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 DesignCreated out of balsa wood and tissue paperWater wheel styleSupported by KenexThree bladesExtremely light
Generator DesignInsulated wire
wrapped around a coke bottle
Wrapped 700 timesPlaced and
supported in a box structure
Earth magnets run within the coils
Connected to the fan
Mechanical 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.
Construction IssuesThe generator
Difficult to createProblem with efficiency
The fanFragileSensitive to moisture
OverallProject was challengingTime consuming
EfficiencyEquationsPtheoretical = ½(ρAV3) – density(air) * surface area(fan) *
air velocityPtested = VA – volts * amps = watts(Ptested / Ptheoretical) * 100 = efficiencyValues
Ptheoretical = ½ * 1.225 * (.11516) * 1.73 = .3465 wattsPtested = 1.4 * .0035 = .0049 wattsE = (Ptested / Ptheoretical) * 100 = 14.14% efficiency
ConclusionProject 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.
