Smart Grids

The 3rd week of SoSC was all about transportation. It was very interesting because I really like cars and talking about them. But we really didn’t talk about cars we talked about how to make a new generation of cars and trucks,highways, and even the subway. We came up with some new ideas like elevated highways, and underground MagLevs. We learned how to program using an ARDUINO and make a robot that uses SONAR , follows a line on a paper. It was a very fun week and I’m looking forward to the 4th and last week “Wireless Communication”.

Carbon Cycle, City Food and Resources and Local, Whole and Organic Foods

I learned about the Carbon Cycle, the process in which carbon is exchanged throughout the earth. Carbon cycles through the Biosphere, Pedosphere, Geosphere, Hydrosphere, and Atmosphere through respiration emissions, photosynthesis, and ocean uptake. Photoplankton absorbs carbon and transfers it through the sea’s ecosystem. I also learned about the difference between Local, Whole, and Organic foods. Local food is food made in the neighborhood. Whole food is food shipped from outside the state or country. Organic food is food without preservatives and pesticides. Finally, I learned about City food and resources, essentially, the things required or needed to create a functionally operating city. Markets, government , and reactions to disasters are important parts of a city as one provides food, leadership and ways to deal with problems we cannot control.

Efficiency in our City

Today, Malique, Dani, Antoine, Kamaya, and I were in charge of making houses. While we were making houses, we kept color reflectivity in mind. Albedo is the reflectivity of an object. Since we knew that the albedo of the color white is low, we planned to make that the color, of the roof. Unfortunately, we were not able to make the roof white today because of time. A pro of low albedo colors on roofs is that it can reflect the sun’s harmful rays off of the building which cools up the building and they do not have to use too much energy for air conditioners and/or fans which helps contribute to saving energy. Other than not being able to finish, today was a very fun day.

Maglev Transportation System

Hi it Renisha, Kayla, Essi, Sean, Brandon and Dylan! Today we started building for our SMART city. Our group worked on transportation. For a modernized transportation method, we worked on using maglev and incorporating them into public transportation like trains and bus. Maglev is powering things using magnetism and the power from magnets. This replaces the use for electricity and reduces the usage of power plants that make coal and produce greenhouse gases. So far, we have “made” a maglev train and bus.

Soil Engineering

Hey blog! Today we talked about soil engineering with Chris. Soil engineering is one of the many jobs that civil engineers do everyday. To build on soil, there must be certain characteristics with the soil. The moisture and stability of the soil is important to know before building a bridge or any form of road. We tested out different types of soil and a combination to see the different states of soil. On Monday, we will see the progress of the different soils separating.

Natural Cycles and Water Waste Disposal and Filtration

I learned about the natural cycles that occur in the world such as the carbon cycle, water cycle, and the rock cycle. The carbon cycle is the transfer of carbon throughout the environment. Carbon travels through trees, oceans, soil and the sky. The water cycle is when water evaporates and condenses, the precipitation occurs releasing the water stored in the clouds. Finally, the water runs off and the process begins again. In the rock cycle, rocks change from Igneous, Metamorphic, and Sedimentary rocks.

Towards the end of the day, we learned pH and water waste removal and filtration. PH is the measurement of hydrogen ions content in a substance/measure of acidity. Water Waste Disposal is the process in which dirty unclean water, not grey water, is filtered back into tap water that can be reused in homes. resin is used to attract dirt together which allows it to be removed. The dirty water is mixed and filtered. Finally, chlorine is added to purify the water. It is then distributed to every day homes for use.  I also learned that continuous filtering of dirty water gradually cleans out dirty particles within the water.

Cycles and Water Filtration

Today in Smart Cities, we learned about Earth’s natural cycles and Water Filtration. Some cycles we learned about were the rock cycle, the water cycle, and the carbon cycle. Each individual cycle is important to engineers for planning, designing, and building a city. Some facts about water are that 780 million people around the Earth don’t have access to fresh water, 3.4 million people a year die from water-related diseases, there are 366 Quintilian gallons of water on Earth, and a burger takes 2,700 gallons of water to produce. Also, the average American flush uses more gallons of water than people in third-world countries use per person. We then did an experiment with pH after discussing what it was. In the end, we filtered water with dirt in it to make it cleaner. Our water was barely cleaned, while some groups had theirs looking almost like water.

Natural Cycles and Recycling

On Wednesday, we talked about many things. We talked about:

-pH: Acidity, turbidity, and hardness (Photo: results of pH test)

-Water: filtration

-Biospheres: eutrophication

-Natural Cycles: Carbon, Rock, Energy, and Water

-Recycling: Saving the environment, greywater (reuse of water)

-coagulation: In blood and in filtering

 

Geo-Engineering

Yesterday we learned about Geo-engineering which is a branch of civil engineering concerned with developing technologies to reduce the effects of climate change. We learned about cloud seeding which is when people use this boat to make water vapor which will make the clouds denser so that the clouds could reflect harmful rays to reduce the effect of global warming and climate change. But my favorite thing that we learned was is about the Algae which produces 80 percent of the worlds oxygen (O2). In the future we will have algae lamps that does not run on electricity, it glows in the dark, and it helps people breathe better.

What does a food sticker say about our food?

When we go to the supermarket or grocery store and buy fruits or vegetables, chances are there is a sticker on it with a 4 or 5 digit number on it. Many times, we think its a nuisance, peel it off and forget about it. But it turns out that this number tells us where our food came from and how it was farmed. A 4 digit number means it is produced conventionally. A 5 digit number starting with a 8 means its a Genetically Modified Organism. A 5 digit number starting with a 9 means its Organic. We learned in the Local Whole Organic Food lesson that there are many terms we can use to categorize our food, and we classify them by how they’re produced and how they’re grown in season in the Fall but is available in our supermarkets year round.

When it comes to a Smart City, reducing traffic volume and congestion in our transportation network is important to the energy efficiency and environmental impact of our cities, in addition to the quality of life of its inhabitants. Choosing what types of food to stock our supermarkets with has a huge effect on the aforementioned goals. Whole foods are not processed and travels less from the farm to the consumer, since it doesn’t have to go to a factory to package or process it. Organic Foods are foods that are grown naturally, without the use of chemicals such as fertilizers, herbicides and pesticides. Organic foods are grown seasonally and are grown the way nature meant for it to be grown.

This organic apple has a 5 digit number starting with a “9”.
