  2. Design Process • When we first began this project, we considered several ideas. • One idea for our windmill consisted of a complex gear system to generate a significant amount of current to light the bulb. • Our group also considered having several magnets spinning in the middle of two large coils of magnet wire. • Ultimately, we settled on our design because we wanted a design that would not be extremely difficult to construct or cause time and money restraints.

  3. Design • After many ideas and trials, we finally settled on a design that was efficient and consistently lit the bulb. • Our project uses an fan propeller to absorb the wind energy, which causes our magnets to spin. • The magnets are positioned every 90 degrees around the nail and alternate between North and South poles. • The magnets spin in a large coil of wire, creating the electric current necessary to light the bulb.

  4. Materials • The materials we used were cost effective and easily available. • Bill of materials: $~25.00 • Tripsto Lowe’s and Radio Shack were necessary. • Our materials include a fan propeller, 400 feet of magnet wire (26 and 30 ga.), three nails, 4 small wooden dowels, and several small magnets.

  5. Construction Issues • One main issue we had during our construction process was that our project was not generating enough current or voltage to light the bulb. • We tried using more wire, but the bulb still did not light. We also tried adjusting the wires and magnets to increase current flow but neither fixed the problems. • However, on Monday night, we were finally able to fix all these issues to create a project that could complete our task. • Overall, our design took ~10hours to construct. (coiling wire is tedious!)

  6. Calculations • For our calculations of power, we used the equations: • Powerin = ½ ρair Av3 and Powerout = Voltage x Amps • For efficiency, we used E = (Powerout / Powerin) x 100. • The radius of the propeller is 3 in. = .0762 m; the density of air (ρair) is 1.2 kg/m3. • Pin= 7.82 Watts • Pout= .117 Watts • Efficiency = 1.5%

  7. Conclusions • During this project, our team worked well together to accomplish the task presented. • As a team, we spent several hours coming up with sketches, ideas, and materials, then we used these to achieve our goal. • We applied several concepts we learned in EF 152 lectures and recitations. • Overall, we worked together, applied EF 152 concepts, and hopefully, fulfilled all requirements for this project.
