2. DESIGN -Basic structure is 2 crossed rods
-Generator (G) is supported inside
-G consists of 2 sets of copper wire wrapped 700 times around tube
-1st rod holds G, 2nd rod has a magnet attached to it and is attached to windmill’s blades
-Fan blows blades, spins rod and magnet, generates electricity, lights bulb

3. MECHANICAL/ELECTRICAL ASPECTS
Wind Power
Causes blades to spin and rotate magnet
Generator
Spinning magnet causes current to flow through wire
Light
Energy from generator lights bulb

4. ESTIMATED EFFICIENCY Power = 0.5 x rho x A x V^3
rho = kg/m^3
A = 48 in^2 = m^2
Velocity = 1.7 m/s
I = amps
Voltage = 1.7 volts
P (theoretical) = watts
P (actual) = Voltage x I = .03 watts
Efficiency = (actual/theoretical) x 100 = 32.2%

5. DESIGN ISSUES Actual design Generator Getting high voltage
Getting our structure together
Knowing what we wanted to build
Measuring correctly
Generator
Making it work
Getting the right kind of wire and stronger magnets
Figuring out how many coils we needed
Getting high voltage
The Generator
We had to get our magnets to spin perpendicularly to our coiled wire

6. CONCLUSION
-Through all the planning and struggling, we were able to put our windmill together successfully and get some voltage out of it.
