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 bottleWrapped 700 timesPlaced and supported in a

box structureEarth magnets run within

the coilsConnected 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 velocity

Ptested = VA – volts * amps = watts

(Ptested / Ptheoretical) * 100 = efficiency

ValuesPtheoretical = ½ * 1.225 * .0383866) * 1.73 = .115513 watts

Ptested = 1.4 * .0035 = .0049 watts

E = (Ptested / Ptheoretical) * 100 = 42.42% 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.
