2. D EVICE D ESIGN :  The insulator is made of a cardboard box  The copper rod goes through both sides of the box and serves as the axle  Red coated, copper wire wraps around the cardboard box forming coils  Four magnets are attached to the axle, inside of the cardboard box  The light is connected to the ends of the wires  A fan is attached to one end of the axle and generates the power to light the bulb when spinning at the appropriate pace

3. E LECTRICAL & M ECHANICAL A SPECTS OF OUR DEVICE :  Mechanical: Straight fan axle linkage Magnets magnetically attached to copper axle, which is spun by the fan or wind power  Electrical: Magnets spin in between the spun coils, which collect and transfer the electrical charge to the light bulb

4. E STIMATED EFFICIENCY CALCULATIONS : For the efficiency of our engine we use the equation: Produced 16 Volts and ~ 0.1 Amps P = I x V = (0.1 A) x (16 V) = 1.6 watts Power generated = 1.6 watts Period = 1 second * Here: E = efficiency Nb = gearbox/ bearings efficiency Area = 49cm 2 Ce = coefficient of performance * 1.225 is assumed as the air density We will combine the two efficiency values and coefficient of performance and let them account for the total efficiency of our generator E = 62.805 % efficient

5. C ONSTRUCTION / D ESIGN I SSUES :  Our first cardboard box was crushed by the pressure of the coils  Two of the magnets snapped into two pieces  The initial wire purchased was not coated and was the wrong size  Difficulty getting the rod to stick to the fan properly

6. C ONCLUSIONS : Basically, our generator works. Concepts learned The gauge of wire does make a difference in the intensity of power generated As well as the coating of the wire Creating motion between a magnetic field and a coated conductor, the change in charge over an area of the conductor will cause a charge to be distributed Problems Wire problems coating and gauge Fan positioning is not perfectly square. Cardboard serves as sort of a insulator and absorbs some of the energy.
