ChargeIt! Chanci King Andrea Lyons Daniel Stutz Dana Zeitlin EF 152 November 30th, 2009
Design • Vertical • Magnet and coils concealed • Magnet rotates • Coils stationary • Shield distributes wind
Mechanical and Electrical Aspects Mechanical • Fan blades rotate magnet Electrical • Opposing poles spinning within the coils creates an electric field
ρ= air density (1.2041 kg/m3) Calculations A= rotor area V= wind speed
Construction • 3 Prototypes • Trashed two • Difficulty spinning • Wood peg • Nails vs. glue • Stabilize PVC
Conclusions Smaller is faster Faster rotation creates a stronger electric current Home Depot is better than Lowe’s
