Physics Final Project

Now that I’m officially done with my final project, I can finally share all the things I mentioned in my piktochart presentation. However, I would like to just give my thoughts on this overall project. I think it was quite interesting to find out ways to search up cheap and clean ways to generate energy. It was in fact quite hard as you either have one or the other. It’s why the designs mentioned may not be familiar to anyone, namely solar cookers. I’ve bee asked a lot on if I had another topic to chose what would it be. I honestly wouldn’t know since this topic I was doing is very interesting. Now to my presentation.

Below is my piktochart presentation and the final product. Compared to my last one, it doesn’t have quite as many visuals to back it up. This is because I figured it wouldn’t wield me too many extra points so I decided to instead, invest that time into research. I think it turned out alright in the end. I put in 3 designs instead of 1 just so there’s more variety for different purposes. In the end, I had quite a lot of fun doing this and I’m quite happy how it turned out.

Due to an error, it won’t let me post the final project here so here’s the link.

Solutions to the Energy Problem

Since my last blog post, I discussed how I didn’t want to share my ideas yet as I didn’t feel like they were fully refined or if they will be the final product. However, in this blog post, I will share some of my ideas to solutions of the power problem.

When researching, I realised how having cheap and clean energy was nearly impossible unfortunately. So instead, I search up the most efficient machines there are that are incredibly cheap for the poor to purchase. Here’s what I came up with:

Solar Cookers: Likely my best candidate for being the best cheap energy source. As the name suggests, it uses solar power to use for cooking. However, there is are downsides, it can only be used for cooking, and can only be used in the day. Because of this, I will likely be putting in multiple machines in my presentation. Solar cookers are incredibly inexpensive, some costing only 5$ to build, and cost nothing to operate as it uses no fuel, making it very clean as well. Now to explain how it works. It’s a mechanism that traps heat from sunlight into the the stove, which heats up the food. The amount of time varies from whether the sun is out or not. When the sun is out in clear skies, it works to the extent of a normal stove which, for the price, is extremely good.

The second way to cheap and affordable energy isn’t actually a machine, it’s an economic trick. The G8 Renewable Energy Task Force found out that the best way to reduce renewable energy costs is to actually to increase their use in industrialised countries. Because the demand will be high then, the cost will increase there, which reduces the costs in developing countries. This is a very simple method that could actually benefit the poor people in the long run.

Last blog post, I didn’t talk much about what I was actually planning to do for it so I’ll do it now. I’m going to make a piktochart presentation which will show all of these methods of solving my problem and more. On my final blog post, I will show all the methods for cheap and sustainable energy and the presentation itself.

 

Cheap, Clean, Renewable Energy

For my final project, I’m looking into way of cheap and clean energy. I chose this because I was interested to see if there was any energy source close to perfect. I mainly also got inspired to this topic by a post that Bill Gates posted to his website called “Gates Notes”. As for how I’m going to present this, I’m once again, likely going to a visual presentation. Now onto the topic

Energy may be the most important thing to have a good life. 

Although the map isn’t clear, the red countries are the ones that consume the most energy while the blue to light blue consume very little. As you can see, Africa definitely has the biggest problem as well as some parts of Asia. Now I know what you’re thinking. “Well to afford energy, they need money so why don’t we focus on poverty first?”. It’s very true that getting energy isn’t free. That’s why I wanted to address another statement in my claim on getting “cheap energy”. Many renewable energy sources like solar panels, wind turbines, hydro power, etc are very expensive to purchase, let alone maintain. A 10 kW wind turbine costs 48,000 dollars to purchase and maintain, for which people in Africa live at 2 dollars per day, owning a wind turbine is a fantasy.

Some people do have a source of energy in the poverty states of Africa. However, a lot of it is unreliable. For example, some people connect bikes as power sources and use the kinetic energy of pedaling to generate energy. Although it works, it requires a lot of work to get the energy, it’s incredibly unreliable with unpredictable results, and it wastes time where the poor people should really be do other things. As of right now, I’m almost ready to be certain of my energy source but I won’t share it in this blog post as it’s not a guarantee.

As for now, I’m continuing to research clean ways to make affordable energy. Here’s the timeline below

Paper Airplanes Test 2

Our previous design had a good exterior but we felt that the material that made it has to heavy and think. We decided to them build a paper plane with the same exterior. We made the plane using normal, thin paper and we tested it out without a rudder. The results exceeded our expectations as when the plane went upwards, it maintained stability and glided down gently. What we learned is this lighter material allows the plane to glide better and maintain stability better.

We did 3 tests in the hallway

8.1 Meters 16.605 Meters 10.53 Meters

Paper Airplane Tests 1

 

Group: Tristan, Tom, Willard

On our first model, we made a pretty big plane with wings angled straight with a flat end at the front of the plane. We tested it several times and it travelled an OK distance but there was room for improvement. First off, we noticed how the plane kept going upwards, regardless of throwing technique. We decided that we’ll angle the wings slightly downward to prevent. We also decided to put a rudder on the back to prevent the plane from twirling.

We’ve made our second design and the main difference is that we’ve added a big rudder on the back to give more stability. We’ve also made it heavy to give more weight, therefore giving more downforce as the plane did go up before. We’ve tested it and it does travel farther than our previous model although a new problem arose as the plane now goes downward. We’ve folded the ends of the wings downward to give more stability and that the airflow downward would hopefully push the plane up. The end result is unclear at this point but we’ve tested it once and it has promising performance.

A Hope of Preventing All of This?

 

As of right now, I’m nearly done with my infographic. I probably need to add finishing touches to it. All around, this has been quite interesting to produce. Because of my relatively long experience with Piktochart, I spent most of the time researching which I would rather do. Overall, this project allowed me to have a better overview of the situation of global warming and it’s ozone layer effects. While researching, I found out something called the “Montreal Protocol”. This action was initiated to lessen the use of ozone depleting emitters such as methane, refrigerants, etc. That’s the good thing to a once worrying situation. However, evidence suggests that ozone depletion is still happening. This could be extremely dangerous since without the ozone layer, harmful UV radiation can get in and damage molecule structures of living things. This is what can affect the future and what makes this scary yet interesting.

 

I’ve designed my infographic to a more colorful tone compared to my light posters that had a certain theme for using 3 – 4 colors and that’s it. I am happy on what I produced since it was easy, simple yet, effective. I didn’t want to create a video or anything that would feel like a chore

to do.

 

Just to add some finishing notes as there isn’t much else to talk about, down below is my infographic. I think I could’ve spent a bit more time giving my infographic more icons and images on it as some parts of it look a bit bland. One part I do like however is the first page talking about the different parts of the atmosphere. There wasn’t any image that could put all this in so I had to implement an icon of Earth, then put in circles that underlap and had different colors to each other. I wanted to make it clear what type of the different spheres there were based on the color. For example, I put the thermosphere as red since but I think of thermo-, I think of heat which I then think of red as in red, hot flame. The exosphere is the part that leads into space so I put stars on the circle and color-coded the text white since black is too hard to see and white matches the stars I put on. The rest of the pages were left quite simple but I liked that idea as I agree with the saying that “less is more”. Wrapping this up, all I would like to say is that this was a surprisingly interesting project that I unfortunately didn’t have as much time as I would’ve liked to have but nevertheless, I hope this would turn out alright.

Heat Is Now Being Trapped In Earth

 

I have researched on my topic a lot now and I can say that I am, myself, very interested in it. I explained how I first wanted to see the different effect on the different parts of the atmosphere and it turns out that only the bottom part (Troposphere) is actually being heated up by global warming. I have looked more into this and it turns out that thinning of the ozone layer, combined with global warming causes the heat to be trapped at the troposphere or below. The stratosphere and above seems to have gotten cooler to my suprise. Normally heat in the Earth would escape to space and is now being trapped inside. This can be quite worrying considering it further increases the heat gain in the Earth. I have already talked about how the sun can send harmful UV radiation and the ozone layer protects us from that. The thinning of the ozone layer causes more of these UV radiation to come in. The symptoms of absorbing this radiation is eye damage, molecule manipulation, and skin cancer.

All of this research is right now being put into my infographic that I am currently working on. For my infographic, I have showed the different parts of the atmosphere and the ozone layer. I will put in more as time comes. I do have a good feeling about completing this infographic because I am able to create it quite fast which gives me more time for research. Currently, I am finishing up my research before I can spend all my time to finish the infographic. Infographic should be finished before Sunday.

I would like to give a bit of background of how I got to this topic. I was always very interested in space. Space is probably my favorite subject in science or overall. When we talked about which of the inner planets was the hottest, I got quite excited because I thought we were going to do a unit on space. When we got to global warming, I don’t want to say I was let down so I decided to relate global warming to space or at least the Earth’s sky. I was just thinking when I remembered when I read a book about Earth’s skies and how it mentioned there was a sphere called the exosphere. The exosphere is the outer and last part of the atmosphere that leads to space. I wanted to do research if global warming affect the exosphere whatsoever and it turns out that there was many more parts of the atmosphere than just the exosphere. That is how I got to this topic right now.
