Problem Statement
Since the last group attached the fan to the shroud using only tape, we have to find a design that give the next group access to easily fix and take out different shrouds to test without any difficulties.

Project Plan
Briefly describe your group's plan for the next 4 weeks, including the specific activities that will take place each week.

Week 1 Narrative
This week we tried to find how to trap air and produce more energy. We are still in the design phase of the project, our task now is to see how the designs of the shroud might affect the air flow through it and to see how much energy can be produced by each design. I found out that the direction of the wind can affect the blades and the speed by the drag force. I also discovered that if the shroud's design was a square then the the air flowing in wouldn't be equal, but if it was a circle then it might equalize and let the air in.

Week 2 Narrative
This week I researched how the PC fan can be used to generate power. There were some steps that are to be followed to to make the fan work.
 * Step 1: First dismantle the fan so we can have easier access to the to the circuit
 * Step 2: Then re-solder the main wires to the wire legs of the copper coil
 * Step 3: Later, we have to test which of the two wires would give the best output in voltage
 * Step 4: In order to convert the power from AC to DC, a rectifier has to be built. it build a rectifier we need to use diodes and the connecting wires. Connect the wires from the fan to diodes by soldering the ends of the wire to the diode and two extra wires to the diodes also
 * Step 5: Connect the extra two wires to an LED and spin the fan to see if the fan generates energy

Week 3 Narrative
This week I worked on creating the a new type of system that can hold the shroud and the fan together. I had come up with two ideas, one was an attachment of a clip, the clip is pressed you are allowed to replace the shroud. the second idea was to screw the shroud into place of an extra piece that attaches to the fan. But because we can't add threads to the shroud, we refined the idea of an attachment with holes on either sides with pins that fit into place around the shroud. We decided that was the best option to start with.

Week 4 Narrative
I created a possible design of the shroud in SolidEdge, although I approached some difficulties while designing the interior of the shroud. Dimensions of the shroud: 12cm diameter of the small side, 23cm diameter on the other end, and 18cm tall. The shroud would eventually fit in the funnel like design and screwed in the fan. I also started working on the Multi-Objective Design of the CDIO Report.
