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

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

ESTIMATED EFFICIENCY Power = 0.5 x rho x A x V^3 rho = 1.225 kg/m^3 A = 48 in^2 = 0.03096768 m^2 Velocity = 1.7 m/s I = .0176470588 amps Voltage = 1.7 volts P (theoretical) = 0.0931883298 watts P (actual) = Voltage x I = .03 watts Efficiency = (actual/theoretical) x 100 = 32.2%

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

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