For this Action Project, I had to: sketch a circuit diagram, construct my circuit representation, build a case to house my diagram, connect my circuit to real energy-efficient solutions, calculate my design's impact, and explain my eco-friendly plan.
However, I began encountering problem after problem in the process of developing this Action Project. First of all, there isn’t a detailed hardware store where I live (Galapagos Islands) where I could buy the materials I needed, and so I had to find my materials through other means. I spent several days riding my bike around town, asking people where I could find resistors and small LED lights. I finally arrived upon an electrical recycling shop a nice man owned, who I became friends with. He gave me a piece of a broken TV where I could retrieve both resistors and LED lights. These materials however, weren’t working so well. Some of the resistors I retrieved weren’t exactly functioning the way they should’ve, and they also weren’t quite the ones I needed.
Also, I needed technical assistance on how to use materials such as the soldering iron, etc. There is a teacher from the school where my Dad is Principal who was willing to help me, but he is usually very busy and can only offer small periods of time per day.
Given the circumstances, I decided to propose to my teachers an alternative Action Project. A co-worker of my dad’s and great friend of mine, Reina Oleas, owns what I believe to be the first and only completely self-sustainable house in the history of Ecuador. She decided to set this project up on her own with the help of her family. Now, given that she lives on the Galapagos islands (there is absolutely no history of anyone trying to set up a project here similar to hers, and therefore no architects that could help or no market to buy from), she had to engineer most of her house on her own. She uses all of the natural resources (sun, rain, wind, etc) that predominate in the region where she lives to make her house work, while her house is connected to no cable and no pipe. She also had to engineer her whole electrical system!
I proposed that my action project be to interview Reina and to focus mainly on her whole electrical system engineering process, to finally think about how I can apply some of the principles she used on my own house. And my teachers agreed!
And so I began developing my proposed Action Project. I told Reina about my proposal to my teachers, and she told me she would be marveled to help. However, she said that if I wanted to focus mainly on the whole electrical system of her house and the journey to fully develop it as it is seen today, I would have to talk to her husband, Mr. Roberto Plaza, given that he was the one in charge of that part of the project. Roberto works as a guide for tourists that come to the Galapagos Island in search for knowledge about these wonderful islands, and has a very busy schedule were he leaves on tourists boats that voyage around the islands for weeks at a time. Thankfully, I managed to contact him and he was only hours from embarking yet again to another tourist trip! He agreed on interviewing him while on his way to being embarked.
I interviewed him for about 30 minutes, and I asked him mostly about his experience in designing his own electrical plan.
He told me that, as they were working on their project to build their energy-efficient house, they realized that the predominant renewable resource they could retrieve electricity from was solar energy. Once they figured that out, they began planning how to install solar panels in their house. They got in contact with several companies from Quito, Ecuador’s capital, and finally agreed on employing one that seemed to fit best. However, they decided to to try installing the solar panels on a smaller house they had, as an experiment to see if this company’s job was efficient.
Once the company had finished their job on the smaller house, they moved into that house to try it out. 24 hours later the power went out, and it never came back. Apparently, the company had made a very basic mistake, and refused to accept that they had done so. The problem was, the Plaza family didn’t face much of a choice, because very few companies offer their services on the Galapagos Islands, and from those few the one they had already employed was by far the best. Also, given that the company had to import all of their material (there is no solar panel manufacturing company in Ecuador), send it all to the Galapagos Islands, and send people to install them, it was very expensive. Roberto contemplated all of these difficulties, and finally decided something that would mark a turning point in the project: He would learn how to design the whole electrical plan for the house and install the solar panels on his own, as well as learn how to provide maintenance. His main sources of knowledge in this process were a great friend of his who accompanied him throughout the whole proceeding and led him to friends who worked on the solar panel business and knew about how to install them, the internet, and a handbook called “Dimensionar tu equipo solar de acuerdo a tus necesidades” (Fashion your solar equipment according to your needs). With these 3 tools, he gradually learned and developed an electrical plan for his home. He realized that the amount of solar panels they needed to buy relied a lot on the type of appliances they were going to use, especially the ones that created heat. He told me about a very cool exercise he did with his family were they all sat together and made a personal plan of the amount of electricity they needed per day. They realized that most of the electricity they used came from appliances that could be substituted by more efficient ones. Something that I feel like makes this exercise very cool is that through it everyone became aware of the amount of electricity they needed, which is not always the amount of electricity we use.
Thus, they got rid of the toaster, the waffle maker, the coffee maker, etc. and found substitues such as the manual coffee maker. Another amazing thing that permitted them to reduce the amount of electricity they used was to take advantage of the wind regarding the architecture to control the temperature of the house. Most of the windows face the side of the house from where the wind comes from, and that way the wind keeps the house cool. However, when it gets a little too cool, you can control the temperature by closing some windows. Thus, the Plaza’s don’t use any air conditioners.
Also, the property in which the house is built is in the high (altitude) part of the island, where it's humid all of the time. Most of the other families that live in the area use de-humidifiers. However, the Plaza’s investigated and found a Chinese method which consists on a series of ventilation chambers placed below the house that permit air to flow below the house, not letting the humidity rise from the ground and reducing it by 20%. Thus, the Plaza’s don’t use any de-humidifiers.
The decided on an estimate of the amount of electricity they needed per day and bought the number of solar panels and batteries that would fit the description.
With the help of the 3 tools I mentioned earlier, Roberto installed the solar panels and batteries, and has given them maintenance ever since. With all the changes they made as a family to reduce the amount of electricity they use on a daily basis, Roberto was profoundly proud to express to me that if you were to turn on all of the lights and all of the appliances of his house at once, you’d be using the equivalent amount of energy of one average air conditioner. He also told me something that he proved in the development of this project: if any family decides to use only the amount of electricity they need, and substitute their appliances for other more eco-friendly ones, they can reduce up to half of the amount of electricity they were previously using. He says that even if you don’t decide to use natural resources to power your house such as solar panels, only re-thinking the way you are using electricity can drastically change your electricity bills and your ecological footprint.
From all of the amazing things this experience has taught me, I will apply in my own home:
- I’ll tell my family about the exercise the Plaza family did to analyze the amount of electricity they were using and the amount they needed, and I will persuade them to try it out. As a result of this exercise, I will consult with my family about which appliances we can substitute or give away.
- My house has some installed solar panels which haven’t been mantained in a long time and are currently not in use; I will ask Roberto to take a look at them and if possible help me with making a budget of how much money and effort it would take to make them work again.
- We are in the cooler months of the year, and therefore never use fans in my house, but I will locate the direction from where the wind comes from, and find ways to take advantage of it to keep the house cool in the warmer months of the year (December through May).
- I will make a budget of how much it would cost to change the light bulbs in my house for LED lights.
I learned so much from this experience and am very thankful to my school for permitting me to develop an idea I had in mind into an Action Project.
