Objective
As part of the Humboldt State University Parras Summer Program, we are students interested in creating technologies that benefit people and the environment. In 2007 a team of students was asked by Josè Leandro Hernàndez to implament a PV system for his store... technologies that ... Research demonstrates that solar energy is an ideal source for low-temperature [1]
Project Criteria
Here is a table of criteria that in our minds define an appropriate technology for the construction of the refrigerator. Competing solutions can be rated on how well they meet each of the following criteria. Then those rating can be multiplied by the criterion weights. The solution with the highest score is the most appropriate.
Criteria | Weight (0-10 highest) |
---|---|
Environmental Impact | 9 |
Functionality | 6 |
Cost(of construction and of final product) | 7 |
Buy back time (economically viable) | 9 |
Simplicity of use | 7 |
Utilizes local materials | 5 |
Safety(for the consumer) | 8 |
Efficiency | 7 |
Planning
Grant Writing
We submitted a grant request to The International Journal for Service Learning in Engineering (IJSLE) for the sum of $1000 USD. The grant discussed the learning possibilities of this project as well as the impact it would have on the community. The grant was submitted on July 4th, 2008.
Collection of Materials
- Broken Refrigerator
The refrigerator was the first part of the refrigerator that we sought out. We obtained it from Gerardo Delgado Ayala at his small, home run refrigerator repair shop at Calle Guerrero #13. The refrigerator had the compressor and other electronics removed. We hope to make use of it for the housing for our project.
