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

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.
