The Silver Bullet bicycle

I am studying a course on Design and Engineering, and this is my last Action Project. The purpose of this Action Project is to create the ideal bicycle for a Chicago commuter. There are some specific design elements, such as the gear ratios and safety features that can differ depending on the user, and I had to thoroughly study my user in order to deliver to her the best commuting bike that will satisfy all of her needs.

In this unit I learned a ton! We learned about wheels; how they have permitted a better form of transportation, and thus united countries and whole cultures. Later we focused on a specific vehicle: the bicycle. Bicycles share with us many liberating possibilities, for example they permit us to cover 3 functions: We can move from one place to another easily, while respecting nature and exercising our bodies.  I also learned about all the different ways that wheels are used around the globe, and of how they really work. I thoroughly studied the wheel and axle, the pulley, and about gears. Later through the unit, we started concentrating more on bicycles. From researching modern bikes I learned that it there are very interesting and innovative designs which keep a bike safe and locked, for example having the handlebar be a lock as well. I also learned that there are other cleaner and better designs of bike chains, which actually don’t use chains at all but rather carbon and plastic. These bike chains don’t need lubrication, and are also silent when riding.

I interviewed a friend of my dad’s called Chris Haskell and I found the way he described how to choose a good saddle for a bike very interesting. He said that “The wings of the saddle have to meet you on your sit bones” . He also gave an example of why saddles need to be hard, where he asked me to “Imagine rubbing your fingers across a smooth surface, like a piece of tile. You can rub your fingers across a piece of tile for a long time and your fingers will not get hot. But if you get your fingers and you rub them across your sheet on your bed, it doesn’t take very long before your fingers get very hot. This is because soft material creates more friction. This is why your saddle needs to be hard.” More friction equals more work for the same speed.

Going back to my Action Project, I designed my bike for a specific user/commuter. Her name is Malia. She is 15 years old, and lives in Logan Square Chicago. She lives 5 miles away from school, and her road to school is filled with access ramps and potholes. She needs a bike with several gear ratios, that will help her not get tired in her 5 mile ride, that will make her feel comfortable even when going up and down access ramps and over potholes, and that will provide extra space for her to carry groceries, school books, and lunch box.

Here is a map of her approximate route:

According to Google maps, it will take her approximately 30 minutes to get to school everyday. Her average speed on her commute will be of about 10 miles per hour, or 4.4704 meters per second.

Malia is looking for an easy, comfortable ride to school and back home. However, if she for some reason is in a hurry, she would like to go faster. So she would prefer a mid-sized cog in the front (39 teeth), and three different-sized cogs in the back (15 teeth, 16 teeth, and 17 teeth).  This way she could use the 17 teeth cog to go up the ramps at the subway stations, the 15 teeth cog to reach high speeds on the road and down slopes, and the 16 teeth cog to cruise. I chose only 3 different gear ratios so that it would be simple for Malia to use, yet productive, fulfilling all of her needs. I chose these specific cog sizes for Malia, her approximate weight being 125 pounds and her preferred travel speed being roughly 18 km/h on her mostly flat journey.

The gear ratios for these sizes would be:

15 teeth 2.6/1

16 teeth 2.4/1

17 teeth 2.3/1

These are exactly the same sizes as the 3 middle gears of the small front gear of the Shimano Sora Gear Shifting  System.

MY BIKE

My bike is a hybrid between a road and a mountain bike, customized for the commuting needs of my user. It has a light aluminium body, with suspension forks on the front wheel, and thin wheels that are both fast and resistant. Similar to the Denny Bike, it comes with an integrated removable handlebar locking system, as well as racks with a flexible storage system in the front AND back, as part of the frame. It also has a fully-integrated turn signal, head and brake lights system, with its turn signals activating with only the touch of a button (pushing the brake handles out instead of in; they turn off with clicking again)  for safety. This is very important, given that she often rides her bike back home at night. My bike includes a removable battery for charging the lighting system, as well as a minimal fender that removes water from the tire itself. Finally, it also comes with a gear shifting system, with the 3 different speeds that Malia will need for her commute. The radius of my bike’s wheels is  14.5 inches long, and its diameter 31 inches.

My bike is better than the competition, because with its light and resistant wheels, Malia won’t have to worry about getting late to school or work ever again. The wheels, along with the different gear speeds, allow the user to reach high speeds with less work than usual.The flexible storage system in the front and back of the bike that are part of the frame itself also allow you to take both big and small delicate objects on your trip with safety. Also, its light suspension forks on the front wheel permit you to have a smooth ride through the usual potholes and ramps in the city. My bike’s unique locking system allows Malia not to worry about her bike’s safety at school, the library or the grocery shop. My bike would demonstrate Potential Energy when at the top of a hill, and Kinetic Energy when Malia is riding the bike to school, to the food market, or back home.

Malia, my user, lives 5 miles away from school, and will have to travel that distance and back every week day. She will have to go on the elevated 606 trail and Milwaukee Ave. This means that she will have to go up and down access ramps, and she will encounter potholes on the Avenues; she also goes grocery shopping on her way back to school. My bike’s lightness and gear-shifting system reduces the amount of force needed to travel her 10 daily miles, including going up and down access ramps. Also, potholes won’t be a problem thanks to the suspension forks on the front wheel. While she is at school and shopping, she can use the bikes handlebar self integrated locking system to keep it safe from someone stealing it. Also, the flexible storage system in the front and back of the bike that are part of the frame will allow her to ride comfortably back home with her groceries. She also needs to have a safe trip back home after school, sometimes at night. Because of this, my bike comes with a fully-integrated, turn signals, head and brake lights system, with its turn signals activating with only the touch of a button, so that cars and other commuters may see her. Given that the circumference of the wheels of my bike is 91.1 inches., they will rotate a total of  8832.84 times before she gets to her destination.

When making my bike I kept in mind all of  Malia’s needs, as well as her age and the distance she will be traveling every day. I also kept in mind all of the things I learned about wheels, axles, pulleys and gears in my Internal Investigation, as well as all of the personal experiences riding bikes that my interviewee shared with me, and the things that he had learned of over time that he thought made his bike experience more productive. Malia should trust in my design because the accessories it features satisfy all of her needs.

One of the obstacles that I ran into when making this Project was that I didn’t (and still don’t) have any experience commuting with a bike. Commuting with bikes is not really part of the culture here in Ecuador. This is probably because it is very hot and humid all year long and people don’t want to get to work sweaty! Also, there are no good bike paths in the city where I live (Guayaquil), and drivers do not take bicycles into consideration. So this forced me to really try to get into the mind of my interviewee, Chris Haskell, who is a faithful commuter and biker who rides approximately 200 miles per week. Another obstacle that I ran into was that most of the math that I learned in order to achieve this project was very new and quite hard for me! But with the help of Khan Academy, I understood much faster than usual.

I am proud of all of the knowledge that this unit has gifted me. One of the things that I learned which I value most is that I was able to realize, by studying different bike organizations, how much a bike can really help someone. In rural communities for many people, bikes are essential in their everyday tasks! This motivated me a lot to learn more about how I can improve bikes and make them more accessible.

My interview with Chris Haskell on the phone, October 2016

La Limpieza Podemos Alcanzar

I am Studying a course about Rhetoric, and this is my third Action Project. It consists of making a piece of art to address a social issue that is important to me. I decided to make a song, which addresses the issue of the lack of cleanliness in my town, Chongón,Ecuador. The name of my song is “La Limpieza Podemos Alcanzar” (We Can Achieve Cleanliness). It is a “Cumbia” song, which is a Latin American rhythm that is popular in  Chongón.

There is a certain neighborhood inside  Chongón called San Geronimo 2, which I visit a lot given that I have a children’s class there once a week, in which I teach kids from 6 to 8 years old about spirituality and values.I have started to realize that there are some problems that the neighborhood has that the locals have never really set their mind on changing because they may seem quite unimportant. However, I have also started to realize that these unattended problems affect not only the children in my class, but the whole neighborhood in general! So I decided to break the sound barrier on one of the problems that I feel is affecting San Geronimo 2 the most: the lack of cleanliness.

My thesis statement

I made my song as a “Cumbia” so that it would attract the locals of San Geronimo 2, and I wrote simple lyrics so that it would be easy for people to sing. My goal in making this song is so that the locals of San Geronimo 2 may open their eyes to this problem, and realize that it is affecting them both emotionally and economically, so that they may get together and work towards reversing this problem.

Here is a recording of the song I made:

Here are the lyrics of the song:

La Limpieza Podemos Alcanzar

Al caminar por mi bello barrio
Gente amable sonrie con fulgor
Niños jugando en el parque veo
Madres y padres juntos van tras ellos

Pero el agua en las calles muy sucia está
Y los niños jugando se mojan sin parar
Debemos limpiarlas pa’ encontrar sanidad
(Pues) Los niños se enferman y para el doctor no hay más

CHORUS
El fuego de la unidad
Se enciende en todos al cantar
La limpieza podemos alcanzar 
Pero todos debemos apoyar

Mi barrio ahora más limpio está 
Y el resultado alegra a los demás
Niños más sanos juegan juntos sin temor
Padres sin la más mínima preocupación

Pero las construcciones en las calles siempre están
Y el polvo que crean a los pulmones van 
Debemos limpiarlas pa’ encontrar sanidad
(Pues) Los niños se enferman y para el doctor no hay más

CHORUS
El fuego de la unidad 
Se enciende en todos al cantar
La limpieza podemos alcanzar 
Pero todos debemos apoyar (Bis)

Here is a rough English translation of the song:

We can achieve cleanliness

While I walk through my beautiful neighborhood

Kind people smile with fervor 

I see kids playing in the park

Mothers and fathers together looking after them.

But the water in the streets is very dirty

And the kids playing fall on them

We need to clean the streets to achieve sanity

Because the kids are getting sick and there is no money for the doctor.

CHORUS

The fire of unity

Lightens in us all as we sing

We can achieve cleanliness

But we must all give a hand

My neighborhood is now much cleaner

And this makes everyone happy

The kids play with no fear 

Parents with no worry

But there is always constructions in the roads

And the dust they create go directly to the lungs

We must clean them to achieve sanity

Because the kids are getting sick and there is no money for the doctor.

CHORUS

The fire of unity

Lightens in us all as we sing

We can achieve cleanliness

But we must all give a hand (BIS)

My Artist Statement

Here are some things I have observed in San Geronimo 2:

• My kids often come with no shoes or no shirts to my children’s class.
• The streets of San Geronimo 2 have been in “repair” for the last 6 months. The work is very slow given that workers don’t get paid enough and on time. This creates a lot of dust, and this brings diseases.
• Much, if not most of the wastewater that comes from the houses of San Geronimo 2 empties out into the street. San Geronimo 2 is situated on flat ground, and the wastewater accumulates and becomes the focus of mosquitoes that can carry a variety of diseases. 
• The wastewater accumulated in the streets makes the whole town smell terrible, and children that play in the street often fall and get wet with this water. This also brings diseases.

“Breaking the sound barrier” means To bring to light problems/facts that go unheard, which often turn out to be very important. With that said, I believe that my song breaks the sound barrier because it talks specifically about two of these facts: the wastewater and dust that accumulates in the streets and their consequences. This is a topic that no one talks about or pays attention to in general in San Geronimo. I decided to start the song by naming all of the good things that San Geronimo 2 has to share, and later I introduce the wastewater problem and its consequences. Then the chorus says that the solution to these problems can be reached if we decide to unite and help clean our neighborhood. Next, it talks about how I see San Geronimo 2 better already, but that the dust from the street repairs is accumulating and affecting us all physically and emotionally. And finally, I repeat the chorus twice.

I used a metaphor to describe unity as a “fire” that lights in all of our hearts when working in harmony towards the improvement of our neighborhood. I also used rhymes throughout the whole song to make it sound much more attractive and easier to sing.

With this song I hope to make the people of San Geronimo 2 see that their neighborhood is full of beautiful people and also potentially a beautiful place, and it is because of this that they should work together to make it better yet. I also hope that they may see that they are presently living the consequences of the lack of cleanliness, and it is bringing them much grief and economic depression. I will share this song with the president of the neighborhood. I will suggest that he organize a cleaning campaign and offer to invite the children from my class to participate. I will also sing the song with the children from my class.

Bill McKibben's 2011 Power Shift Annual Youth Summit Speech Prezi

I am Studying a course about Rhetoric, and this is my second Action Project. It consists in demonstrating my understanding of rhetorical appeals by making a presentation in which I can educate others about a certain rhetorical challenger of the status quo from recent years. I chose Bill Mckibben, and his 2011 speech in the Power Shift Annual Youth Summit. I hope you enjoy!




Here is the speech thoroughly annotated, highlighting the rhetorical appeals and devices separately:

Text of the speech:

All right, listen up. Very few people can ever say that they are in the single most important place they could possibly be, doing the single most important thing they could possibly be doing. That’s you, here, now.

You are the movement that we need if we are going to win in the few years that we have. You have the skills now. You are making the connections. And there is no one else. It is you.

That is a great honor and that is a terrible burden. There is no one else.

The science is the easy part in this, grim, but easy. 2010 was the warmest year on record. And it was warm. We were on the phone one day with our 350 crew in Pakistan and one of them said, “It’s hot out here today,” and I was surprised to hear him say it because it’s usually hot in Pakistan during the summer. He said, no it’s really hot. We just set the new, all time Asia temperature record, 129 degrees F. That kind of heat melts the arctic. That kind of heat causes drought so deep across Russia that the kremlin stops all grain exports. That kind of heat causes the flooding that still has 4 million people across Pakistan homeless tonight.

It’s tough, it’s grim, but the good news at least is that it’s clear, the science. We have a number: 350 parts per million. 350, the most important number on earth. As the NASA team put it in January 2008, “any value in the atmosphere greater than 350 parts per million is not compatible with the planet on which civilization developed and which life on Earth is adapted.” Getting back to 350 parts per million will be very very tough, the toughest thing human beings have ever done, but there is no use complaining about it, it’s just physics and chemistry. That’s what we have to do.

But if the scientific method has worked splendidly to outline our dilemma, that’s how badly the political method has worked to solve it. Think about our own country, historically the biggest source of carbon emissions. Last summer, the Senate refused to even take a vote on the tepid, moderate, tame climate bill that was before it. Last week, the House voted 248 to 174 to pass a resolution saying global warming wasn’t real. It was one of the most embarrassing votes that Congress has ever taken. They believe that because they can amend the tax laws they can amend the laws of nature too, but they can’t. I’m awful glad a few of you went up to the visitors gallery to talk some sense to them last week.

Even the White House. Two weeks ago, the interior secretary, who spoke here two years ago, Ken Salazar, signed a piece of paper opening up 250 million tons of coal under federal land in Wyoming to mining. That’s like opening 300 new coal-fired power plants and running them for a year. That’s a disgrace.

But you know what. We understand the physics and chemistry of political power. In this case, it’s not carbon dioxide that rules the day: it’s money.

Many of you are in the District of Columbia for the first time and it looks clean and it looks sparkling. No, this city is as polluted as Beijing. But instead of coal smoke it’s polluted by money. Money warps our political life, it obscures our vision, but just like with physics in chemistry there is no use in whining. We know now what we need to do and the first thing we need to do is build a movement.

We will never have as much money as the oil companies so we need a different currency to work in, we need bodies, we need creativity, we need spirit.

350.org has been like a beta-test for that movement. It began with youth here at Power Shift four years ago. It’s now spread around the planet. In the last two years, there have been 15,000 demonstrations in 189 nations. CNN called it the most widespread political activity in the planet’s history. But it needs to get bigger still. On the first Earth Day in 1970 there 20 million Americans in the street, one in 10 Americans. That’s the kind of size we need.

And so, on Sept. 24, we need your help. Sept. 24 is the next big day of action. We’re calling it Moving Planet and in those 189 nations, people will be in motion. Much of it will be on bicycles, because the bicycles is one of the few tools that rich and poor both use. Who here knows how to ride a bike? Alright, Sept. 24, I cannot wait to see the pictures. We are not going to wait for the politicians to move, we’re going to create the future that we need ourselves.

But that movement doesn’t just need to be bigger, it needs to be sharper too, more aggressive.

You know what, at Copenhagen we got 117 nations to sign on to that 350 target. That was good, but they were the wrong 117 nations. They were the poorest and most vulnerable nations. The most addicted nations, led by our own, weren’t yet willing to bit the bullet, so that’s where we’ve got to go to work.

That work, to deal with that money pollution, that work starts Monday at 10 o’clock in Lafayette Square, across from the White House and next to a place called the U.S. Chamber of Commerce.

The Koch brothers are high peaks of corruption, but the U.S. Chamber of Commerce is the Everest of dirty money. It boasts on its web page that it is the biggest lobby in Washington. In fact, it spends more money lobbying than the next five lobbies combined. It spent more money on politics last year than the Republican National Committee and the Democratic National Committee combined and 94 percent of that went to climate deniers.

We cannot stop their money, but we can strip them of their credibility. They claim to represent all American business, but they don’t. 55 percent of their funding came from 16 companies. They don’t have to say who those companies are, but it’s easy to tell when you watch what they do. They spend their time lobbying to make sure the planet heats up as fast it possibly can.

They sent a legal brief to the EPA last year, saying that they should take no action on climate change, because if the planet warmed, humans could alter their behavior and their physiology to deal with the problem. I don’t even really know what that means, alter your physiology. Grow gills? I don’t know. But I can tell you this. I am too old to change my physiology and you all are too good looking. But I will adapt my behavior. Every day now I will roll out of bed and go to work fighting them. Hell, I will go to bed at night and try to dream up new ways to fight.

We’re going to adapt our behavior all right. We’re going to adapt our behavior now to fight on every front. I’m sorry if that sounds aggressive, but there we are.

Twenty-two years ago, I wrote the first book about climate change and I’ve gotten to watch it all, and I know that simply persuasion will not do. We need to fight. Now, we need to fight non-violently and with civil disobedience. You will hear from my friend Tim DeChristopher in a moment and more to come, but if you’re going to go that route, one thing you need to make sure that you manage to get across in your witness is that you are not the radicals in this fight.

The radicals are the people who are fundamentally altering the composition of the atmosphere. That is the most radical thing people have ever done.

We need to fight with art and with music, too. Not just the side with our brain that likes bar graphs and pie graphs, but with all our heart and all our soul. Tomorrow or tonight, you need to go down behind Hall B downstairs and help them build the artwork for Monday morning.

We need to fight with unity. We need to have a coherent voice. That’s why, last week we joined with our friends at 1Sky to build this bigger, stronger 350.org. We need to speak with one loud voice, because we are fighting for your future.

So far, we’ve raised the temperature of the planet 1 degree F and that’s done all that I’ve described, it’s melted the arctic, it’s changed the oceans. The climatologists tell us that unless we act with great speed and courage that 1 degree will be 5 degrees F before this century is out. And if we do that, then the world that we leave behind will be a ruined world.

We fight not just for ourselves, we fight for the beauty of this place. For cool trout streams and deep spruce woods. For chilly fog rising off the Pacific and deep snow blanketing the mountains. We fight for all the creation that shares this planet with us. We don’t know half the species on Earth we’re wiping out.

And of course, we fight alongside our brothers and sisters around the world. You’ve seen the pictures as I talk: these are our comrades. Most of these people, as you see, come from places that have not caused this problem, and yet they’re willing to be in deep solidarity with us. That’s truly admirable and it puts a real moral burden on us. Never let anyone tell you, that environmentalism is something that rich, white people do. Most of the people that we work with around the world are poor and black and brown and Asian and young, because that’s what most of the world is made up of, and they care about the future as anyone else.

We have to fight, finally, without any guarantee that we are going to win. We have waited late to get started and our adversaries are strong and we do not know how this is going to come out. If you were a betting person, you might bet we were going to lose because so far that’s what happened, but that’s not a bet you’re allowed to make. The only thing that a morally awake person can  do when the worst thing that’s ever happened is happening is try to change those odds.

I have spent most of my last few years in rooms around the world with great people, many of whom will be refugees before this century is out, some of whom may be dead from climate change before this century is out. No guarantee that we will win, but from them a complete guarantee that we will fight with everything we have. It is always an honor for me to be in those rooms. It is the greatest honor for me to be with you tonight.

No guarantee that we will win, but we will fight side by side, as long as we’ve got. Thank you all so much.

Max Shovel

I  am taking  a Design & Engineering course at my school this period, and this is my presentation for the first Action Project. In this course I have learned to see that sometimes we don’t use the appropriate tools for the jobs that we do throughout our lives, or even our everyday tasks. I have also learned about wedges, levers, inclined planes, and how the tools we use actually work! The purpose of this Action Project is to re-design a tool in a way that it may be easier and more productive for elderly gardeners. In the previous units we have learned about a series of different  aspects that could make a tool easier to use for an elderly gardener, and now we must consider these aspects and put them in practice by re-designing a specific tool. We also studied a lot about empathy, and I realized that empathy is a virtue that permits us to learn from others, and to focus on other’s needs instead of ours. This virtue relates to this project because we are not part of the target group, so to design a tool for them we must learn to think and act from their perspective. The only way to achieve this is by empathy.

I designed a fiberglass round point shovel called Max Shovel. Its lightness and grip permits a gardener to have a less laborious experience when digging, especially in rocky dry soil.

I interviewed my friend Jimmy, who is approximately 65 years old and has been working on a  garden across the street from his house for about one and a half years, and I learned that a common problem that he faces is that his shovels after some time of use get dull, and this makes it very hard to dig, especially in rocky soil. Another problem with shovels, he said, is that the blade always gets loose after some time. Also that the shovels with wooden handles are very heavy and slippery without gloves.

He also told me that when he couldn’t use the proper tool for a specific task (because it wasn’t available to him), it would take him up to three hours more than usual. For example, before he had a hose for watering his garden, he would fill up buckets of water, and it would take him two hours to water all of his plants. Once he bought the hose, however, it would only take him half an hour to water his garden, and he could be doing other things while watering, such as transplanting new small trees.

Something that he said that interested me a lot was that “Mostly I use the pick and the shovel... I need the pick to open the holes because I can’t put my shovel into this ground...”. I checked his shovel out and it had a wooden handle, and a loose, dull steel blade.

The way shovels work is pretty simple. At first, it works as a wedge when going through the topsoil; then it acts as a lever, using one of the gardener’s arms as the fulcrum and the other arm as the one to apply force, and the dirt and rocks on the blade of the shovel as its load.

I went to a hardware store near my house called Ferrisariato, and there I learned that round point shovels are made for digging, and square shovels are made for carrying material from one place to another. I picked a round point shovel for this project because the idea is to improve the digging experience. I also realized that long shovels don’t have a handle at the end, because these handles are made to carry material from one place to another easily, and long shovels work better for digging only. I also did some research on the Internet and I realized that fiberglass is being used more and more for shovel handles, given that it makes them lighter and more resistant.

My Max Shovel consists of a titanium blade that is more resistant and lighter than the usual steel, as well as a fiberglass and wooden handle with grips and guidelines that indicate where to place your hands for more efficiency. Normally shovel blades become loose because the wood from the handle of the shovel starts getting old, so the nail holding the blade becomes loose. Fiberglass doesn’t lose its shape as fast wood, so the blade of the Max shovel will remain tight longer than others.  As an extra feature, it comes with a screwable extra handle stick and an ending handle. All you need to do to change from a long shovel to a short one is unscrew the long handle and screw in the short handle. All of these extra items come in a light-weight small bag that you can take anywhere.  

One of the obstacles that I ran into was that there is no store in my city that sells fiberglass shovels, so I had no way to try these out. However, I did a lot of research on the Internet, and based on the weight, the expenses, and peoples’ experiences I decided that this would be the best material to use for my handle. Once I made my first prototype, I realized that one of the most common problems when buying shovels is that usually people don’t only buy one, they have to buy many of different sizes! My design did not have a backup plan for resolving this, and it was something worth paying attention to. So I came up with a way to make two shovels in one.
