 * Problem Solving Activity: Great Pacific Garbage Patch ** ||
 * __ DESIGN BRIEF / SPECIFICATIONS: __**

The garbage patch is massive and floating around lose in the Pacific Ocean. The world has made plastic an illegal substance and is no longer used. A derivative from natural products has been developed to replace plastic. The new product is now biodegradable and will not harm the environment but the problem of the Great Pacific Garbage Patch needs to be solved. Your design team has been contracted to start removal of as much garbage as possible and transport to a Co-Gen plant. You must organize your team into a job oriented tasks working efficiently to design a system that will remove the various sizes of debris.


 * Keep these ideas in mind: **


 * Sizes of material to removed. Some may be large but remember some are microscopic. How will you handle each situation?
 * The composition of the material will vary. (Different types of plastic)
 * You may not harm any existing sea life during the extraction process. Sea creatures can not be sucked into the system and discharged.
 * The area is about the size of Texas. Your machinery will be mostly very large or a system of interconnecting components.
 * You must have a containment system to hold and transport your debris to an off-site facility. This system may be described in an essay. Discuss how it will be moved to be transported. What it will be transported in? Where the materials will be taken? How will the material be offloaded and moved to the disposal plant?
 * Remember you are in the Pacific Ocean; there will be waves, wind, rain, and hurricanes. Your machinery must be able to ride the waves.


 * Design Development Plans **

Brainstorm ideas on systems that may not even been invented, but keep it real. You may also modify an existing system to accommodate your needs. Research on the internet items that may be modified and repurposed. You are not designing a freighter or tanker ship, you are design the extraction / collection system. However, it must be of a large realistic scale and either retrofitted into an existing vessel or float.

The team will be designing at a minimum the following:


 * Develop ideas on how to clean up the mess.
 * o Intake system.
 * o Filter / extraction system
 * o Containment system
 * o Removal to disposal ship
 * o Transportation to disposal site
 * o Synopsis of how system functions.

Begin with:

Preliminary Design:
 * Develop sketches of your ideas on graph paper. Each member of the team is responsible to developing a portion of the project. Remember each person will design a portion and in the end it must all fit together. In the preliminary design stage is were you want to discuss and coordinare sizes and parts. Do not leave that to the end and find that your parts do not fit together.

Final Design:
 * Develop a final preliminary design plan with notes and details of how your system will work.
 * Final hand drawn sketches will be scanned and uploaded to the wiki page.
 * Keep in mind that your system must not cause any harm.
 * Your final design will be designed on the computer.
 * Each portion of the design must be drawn as an individual object and assembled in a master drawing. Each team member must be responsible for a portion of the drawing and assembly.
 * Your team will develop working drawings that consist of three views with dimensions and an isometric.
 * Also a complete overall view of your operations and an exploded assembly.
 * Drawing will be uploaded to the wiki page.

One last item, what will you do with the recovered waste.


 * Your team must find a site near your clean up area that will take your debris.
 * Provide information about the Co-Gen plant and volume of material it can take in a day.
 * The team must come up with a transportation method to Co-Gen site.
 * Locate a site, find a harbor and route.
