Design Overview..

• Wanted to make it small and simple• 6” by 2.5” box•Used plexiglass, 36 gauge magnet wire, Styrofoam cups, wooden rod, magnets, used air wick bottle.• Only cost roughly twelve dollars

Design AspectsElectrical Aspects

o The turning of the magnets to produce a charge in the wire

o Lighting of the light bulb from the charge

Mechanical Aspectso The cups harnessing the

wind from the fan to turn the wooden rod.

o Small box and wooden rod so that it turns faster and is more efficient

Calculations Pin= .5 (p)(A)(V3) p= Air density A = Rotor Area V = Wind speed P = 10.7 Watts Pout = Plight bulb

Efficiency = Pout / Pin

Eff = 9.3%

Design and Construction issues To big of a box Using a nail instead

of wooden rod at first so magnets would not stay on

Not enough wire initially

Cups coming off from to much wind

Conclusion Working as a team we took our given

objective and thought of a solution to harness the wind successfully.

Learned from our mistakes Took everyone’s ideas into consideration Nothing is 100% efficient or guaranteed!
