Product viability
· Loads. How will loads be transferred from the environment to your product, and how will loads be transferred within your product? Will the loads be static (unchanging) or dynamic (changing)? How can you calculate the loads? Will the components of your product be able to withstand the magnitude of these loads?
Our product would be able to withstand the loads from the environment. The loads would be heat generated by the motor when the motor is converting the kinetic energy into useable electrical energy. A casing around the generator and motor would prevent the motor from being affected from the temperature change in the environment, so it would be able to withstand the heat during the summer, and the cold during the winter. The loads that will be affecting our product will be dynamic loads because the temperature and generated heat are changing variables. We can calculate the heat generated by allowing the motor to continue to run until the rise in the amount of generated heat becomes stops rising or until the motor becomes inefficient due to the generated heat. We could measure how the loads from the change in temperature affect the motor by allowing the motor to run under a heat lamp to simulate summer conditions. Then we could allow the motor to run in a freezer of a refrigerator to simulate winter conditions. Then we would compare the results of how efficient the motor operated in both environments. In general, yes, we do believe that our product will be able to withstand the loads put on it.
· Materials. Will your choice of materials withstand the test of time? Will the density/weight of the materials adversely affect your design? Will mechanical properties of your materials provide sufficient strength, stiffness, and abrasion resistance? Will the material be able to withstand repetitive loading without premature failure? Will the material operate well within the range of temperatures to which the product will be subjected? How will the material react to sunlight, temperature variations, chemicals to which it will be exposed?
The materials will be tested for resistance of weight and the magnetism, materials must resist to different temperatures and other environmental factors. Our materials will be tested for more than one time to ensure the efficiency of the product. The materials will be as light as possible to limit the weight of the product. All of the materials will provide sufficient strength, stiffness, and abrasion resistance for the product, to increase the survivability of the product. The entire product will be resistant to temperature variations, chemicals, water, humidity, and sudden impacts such as drops or falls.
· Mechanical Engineering. Does your design require an input of heat or mechanical power? Are there moving parts in your design? What simple machines are employed in the design? Will all the components of your product interact effectively? Will the loads be efficiently transferred from part to part? Do all the parts move at an ideal speed?
Our product would requires kinetic power generated by the magnets on the edge of the fan blade. The moving parts in our design would be the fan blade and motor. In our product, we are using screws as our simple machine. All components in our product would interact effectively with using minimal parts.
· Energy. Does your product require an input of energy? In what form is the energy supplied? How is it converted by your product to produce the desired output?
Our product requires kinetic energy created by magnets on the fan blade. Then, this energy would turn the gears inside of the motor to produce electricity.
· Chemical/Bio Engineering. Does your design involve conversion of raw materials to another form during manufacture or use? What chemical or biological transformations are involved in the process(es)?
We have no chemical or bio engineering in our product so this is not applied to our project.
· Electrical Engineering. Will your design involve electricity, electronics, control systems, telecommunications, or computers? How will these systems be integrated into your design?
The outcome of our product is electricity, our product does not include any kind of control system or computers.
Have you researched laws, codes, and regulations that could potentially impact your design? Do you feel that your team has met its ethical responsibility for technical expertise related to the design of your product? If not, perform additional research at this time. Revise your product design as necessary.
On October 3, 2014 the Consumer Product Safety Commission was able to publish codes and regulations for magnets. It said that magnets must have a flux index of 50 kG^2mm^2 or less. The flux index is determined by the method described in ASTM F963-11, Standard Consumer Safety Specification for Toy Safety.

However, the codes and regulations for magnets were removed on March 7,2015 to benefit consumer protection, imports, kids, safety, and law enforcement.

UPS shipping regulations for shipping lit
https://www.ups.com/media/news/en/us_lithium_battery_regulations.pdf
There is not much regulations that will affect our product through its manufacturing phase. There is a UPS regulation on transporting lithium batteries but our product at the moment is not designed to contain any batteries.
Create a graphic to document your product’s anticipated life cycle. Research the efforts necessary to take your product from raw materials to the end of its life cycle (and potentially be reused or recycled into new products). Detail each phase of the cycle with information specific to your product. For example, in the Raw Material Extraction phase, indicate the raw materials that must be obtained in order to create your product. In the Material Processing phase, detail the processes necessary to convert the raw materials to usable substances in your product. In the Assembly and Packaging phase, detail the anticipated method of assembly (one-off, hand assembled, human assembly line in a large manufacturing facility, fully automated robotic assembly, etc.) and the anticipated type of packaging that will be used.

Consider the consequences of the development of your product at each phase in its lifecycle to people (designers, users, nonusers, employees of the manufacturers, distributors, sellers, etc.), the environment (including the use of nonrenewable natural resources; the potential release of toxins, waste, or pollution; the creation of visually unappealing facilities or noise pollution; the effect on animal and plant species, etc.), and society.
Building the factories to manufacture and assemble the product will have a definite impact on the environment. The factories will be nicer to look at than factories where they manufacture steel, or other raw materials. The factories shouldn’t produce much noise, it will produce some noise but not enough to greatly affect the surrounding environment. Manufacturing the individual parts of the product will result in producing toxic gas such as calcium oxide. Building the factories will also impact the environment when the factories are being built. This is because factories need a large amount of space to be built, and if there is not enough space already on the build site, the surrounding environment will have to be removed to make more space. This would result in affecting the natural plant and animal species that live in that area. During the shipping process of our product, the transport that delivers the finished product will produce CO2 emissions which will result in more air pollution. And during the End of the life phase for our product, Chemical gases would be produced from melting down the plastic from the product, Carbon dioxide from the fossil fuels that are used in the furnaces to melt the plastic, and Calcium oxide will be produced from developing new neodymium magnets.
Compose an ethical justification for further development of your product by describing why and how the benefits of your product outweigh the negative impacts.
Further developing our product will allow us to improve our generator and maximize its power output while further reducing the cost of the generator. This will allow more people around the world afford the generator, and the generator will be able to power more items in their house, allowing the customer to save more money. We would also improve the way the generator operates by reducing the number of magnets on the motor but retaining the power output. This would make it so that we don’t have to use as much magnets as before the improve which would reduce the amount of toxic gas emissions during the manufacturing process. Also we would improve the material that the casing of the generator and the generator itself is made of to make it more environmentally friendly and easier to dispose of. So this would reduce the amount of pollution produced from the disposal process of the generator once it reaches the end of its lifespan.

summary
For the Part F of our capstone project, we started by answering the questions that were related to our product in math, science, and engineering concepts. Then, we researched the regulations and laws that would impact our product during manufacturing, shipping, and disposing. After that, we made the visual lifecycle of our product from premanufacturing to its end of life. Then, we needed to consider the consequences at each phrases in life cycle to people and the environment. Then we came up with a justification for further improving our product and explained why further improvements outweighed the consequences of doing the improvements. Then we created a poster of our final annotated sketch on which other classmates provided us with questions and ideas that we could use to improve our design more and also get an idea of what type of questions we will be asked during our final presentation.
