This project explores a unique vertical design incorporating concealed magnets and stationary coils. By rotating the magnet while the coils remain still, an electric field is generated through the opposing poles, maximizing energy conversion from wind. The construction involved creating three prototypes, with lessons learned about material effectiveness and stability. The findings suggest that smaller designs yield faster rotations, leading to stronger electric currents. Overall, this innovative approach demonstrates a promising method for harnessing wind energy efficiently.

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
