“ Hit or Miss”

Design

Simplistic design:1. Propeller2. Horizontal Axis3. Magnet4. Copper Wire5. Stand

Design/Construction Issues

o Propeller• Catching enough

wind• Turning the

horizontal axiso Wire• Not having right

kind• Wrapping the

generator the best way

• Having enough to form a strong magnetic field

o Horizontal Pin• How to make it

Frictionless.o Magnet • Best magnet• How to attach to

produce magnetic field.

Mechanical/Electrical Aspect

• Horizontal pin used to easily collect a direct wind source

• Horizontal pin needs to be frictionless to produce the most energy.

• Connecting the copper wire and wrapping it to form a current with the rotating magnetic field.

Estimated Efficiency Equations• Kinetic energy of fan:-KE= (1/2)mv^2M= mass in kgV= velocity of fan blades• Power of wind in watts:-P= (1/2)mv^2 = (1/2) ρ(air) Av^3A= area exposed to windV= wind speedRho= air density about 1.225 kg/m3

- It would be impossible to be 100% efficient due to resistance, friction and human error.
