Week One: Civil Engineering and Environmental Engineering
Windmill and Generator
Summary
In this project, students are introduced to the method of generating electricity using wire and magnets, as well as the engineering design process. Based on this information, students are asked to assemble a windmill.

- Design a sample on TinkerCad
A sample model is the first step to creating a windmill design, with focus being placed on a stable base and making use of given materials.
2. Optimize blade shape
2. Optimize blade shape
The blade shape determines how the wind interacts with the blades, with drag needing to be reduced and lift increased. A blade with a thinner tip achieves this.
3. Optimize blade angle
3. Optimize blade angle
An efficient blade angle allows for greater torque and speed. A balance was needed between the two and thus we settled on 45 degrees.
4. Construct windmill
4. Construct windmill
Constructing the windmill itself allows for testing of the chosen design, identifying problems, and implementing solutions to said problems.
5. Constructing the motor
The motor, created by putting strong magnets on the rotor and surrounding it with copper wire, creates electricity to light up a LED.
6. Final prototype
A windmill with blades of large surface area and large torque, sacrificing speed for a greater generation of mechanical power.
