Pandora Promise Review

“Nuclear Industry is a death industry”. This are the words that movie opens up with. The first topic that the documentary touches is Fukushima. After the tsunami the city was ruined and also the land had radiation, that’s why the person who to visit the place  had to wear radiation cloths. After Fukushima situation, they talked about the  atomic bomb dropped in Hiroshima and all the damage caused and all the damage caused by the radiation. In 1950 2000 nuclear weapons were tested, and two kinds of reactors were developed one called Britter and the other one light water. Britter brits plutonium and is recycled. Light water is mostly used for submarine but also produces a lot o waste. The first commercial power plant was build in Pennsylvania in 1956. In 1980 in east of Long Island, the word that a nuclear plant was going to be build and people try the best of them to stop that from happening. In the movie they talked about that radiation comes from everywhere like from food plants roads etc. While i was watching the documentary i was surprised when i saw the Brazil had a higher radiation than Chernobyl,Ukraine,  due to the explosion years ago and also that the fabric that was in there. It also said that most of the explosions had happened due to quick cooling. I believe that nuclear power is a good source of energy, nuclear power is reliable, and the waste is small in quantity comparing to fossil fuel waste, and is also a clean way to produce energy as it does not result in the emission of any of the poisonous gases like carbon dioxide, sulfur dioxide or nitrogen dioxide. But it can be very dangerous if is not well taken care. And big disasters can happen from an explosion of a  nuclear power plant .

In this weeks blogs i don’t have ,much to say. Last Friday when the class did the experiment and took the measures i was not present due to Health problems. On Thursday one of my classmates Juan  email me his data. On the data were to graphs which i made some changes, reducing the number of x-axis an and y-axis. Then in class i did two more graphs of was potential energy and battery discharge and the other one was power and power level. From the graphs i made a found a positive correlation meaning that as X values would increase the y values would also increase. photo

The way i made this graphs was by using windows excel, and named each data for x and y also put the title. First i copied the data from the top then paced them in the bottom of the two previous graphs, then i made the scatter plot and insert for each data. then draw the linear trendline to help me better understand the relationship between x and y values.

Demand response

Many countries in the world make a large consumption of energy. United states ranked in the second place for the largest energy used per Capita. When oil and other fossil fuels turn into energy they case pollution which leads into gasses being emitted to the atmosphere and rise of global warming. Many of us today take advantage of electrical energy used in at our homes, what i mean is that we are used to miss usage the energy, we leave the lights on most of the time even at day time which is unnecessary. I believe that Demand response will help us better use the energy. Sources:http://www.edfenergy.com/energyfuture/oil-generation .

Demand response is also known as the load response, are programs that are made to enable costumers to contribute to energy reduction. These programs also offer reasons to reduce the use of energy.Demand response give an opportunity for consumers to play a significant role in the running of the electric grid by reducing their electricity usage during peak times.  Electric System planers are using demand response programs as a way to balance supply. This type of programs can lower the price of electricity, and lead t lower retail rates. Source: http://energy.gov/oe/technology-development/smart-grid/demand-responsedemand-glendale

 

Obama’s Clean Power Plan

In 2013 President Obama announced new actions to reduce carbon pollution. At the United Nations on September 23, President Obama participated in the Climate Summit, (a meeting of world leaders to showcase climate action commitments from governments. The president talked about the actions that the United States is taking to reduce the pollution produced, president Obama announced new actions to strengthen global resilience to climate change and also participation with partnerships to cut carbon pollution. The Climate Action Plan is working very well, In 2012 U.S. greenhouse gas emissions went down  to the lowest level. When Obama took office the wind energy production has tripled, and solar energy has increased. Few actions were be taken in order to strengthen global resilience. Here are 3 of them.

1) Executive Order on Climate-Resilient International Development. (Agencies were required to factor climate-resilience into the U.S. government’s international development work.)

2)Releasing Powerful New Data to Enable Planning for Resilience.(To empower local authorities to make a better plan for the impacts of environmental changes.)

3)Developing New Outlooks for Extreme-Weather Risk. (To reduce harm from extreme-weather events occurring throughout the world.)

What is the Environmental Protection Agency is doing in order to reduce the pollution? Going through their website i  read that Environmental  Protection Agency (EPA) is using its authority to issue regulations that address carbon pollution from power plants. In the website it also talked about reducing carbon pollution from power sectors.On September 20, 2013, EPA  proposed carbon pollution standards for power plants built in the future.On June 2, 2014, EPA, when President Obama’s Climate Action Plan came out it proposed a commonsense plan to cut carbon pollution from existing power plants. The clean power plan will maintain an affordable energy system, while cutting pollution and protecting peoples health  health and environment. Source: http://www2.epa.gov/carbon-pollution-standards/what-epa-doing. 

The clean power plan can help us in the long term making our lives better, some of us dont think about the long term consequences of our actions. The same thing happens with global warming many people don’t take it serious and that is why global warming is increasing due to the gasses being emitted to the atmosphere  But what are some of the benefits that we can get out of the new clean power plan. According to the EPA Administrator Gina McCarthy the clean power plan will

  • Cutting carbon emission from the power sector by 30 percent nationwide below 2005 levels, which is equal to the emissions from powering more than half the homes in the United States for one year;
  • Cutting particle pollution, nitrogen oxides, and sulfur dioxide by more than 25 percent as a co-benefit;
  • Avoiding up to 6,600 premature deaths, up to 150,000 asthma attacks in children, and up to 490,000 missed work or school days—providing up to $93 billion in climate and public health benefits; and
  • Shrink electricity bills roughly 8 percent by increasing energy efficiency and reducing demand in the electricity system.

Library Tour

Today we did’t an usual class room day, instead today’s class was a tour around the Mildred F.  Sawyer Library. First i was lost because i didn’t know where i was suppose to go, i was addressed to the information desk by the on of the girls who worked at the check out section. At the information desk the our lady came and introduced her self to us. First thing we did a little tour around the second floor of the library, she told us how to use us how to print from the library computers using our student cards.Each paper printed is 5 cents, and our card has a found of 25 dollars available for us to use and is refunded every semester. Then we went to the third floor where you can find study closed areas, where groups of students work together, these small rooms are first come first serve. In the third floor you can also ask to borrow a laptop and work.After we went to the 4th floor in one of the computer labs. The tour instructor told us how to use the library main page and make a little research on a science topic. The website is http://www.suffolk.edu/sawlib/index.php first thing we had to do was to go under data base and chose science. After that a list of science related  showed up, first we had to click on general science and then another list of topics showed up. The topic i chose was Nature journals online and searched for ocean life. Then after i went through few articles, i chose one about ocean life and how is decreasing due to the amount of gasses on the ocean. After everyone made their presentation we got dismissed.

Building Robots

Through out the week of 9/9 and 9/16 i had to build a robot. When we were introduced to this project to build the robot we had to work in group of two, i worked in a group of three. Me and my group struggled on building the robot because our box had missing pieces. However we managed to finish the robot in time. We build the robot following 6 main steps:

1)Preparation.

First we attached double black peg connector  vertically on the top holes of the machine and a single black peg connector in the middle hole of the machine.

2)Attaching the motors

We attached the motors one on each side of the machine, by attaching it to the peg connectors on both side of the machine.

3)Support Motors

We took an 11-holed rounded beam and attach two short black connector pegs to the outside holes then we attached the pegs to the back of each motor.

4)Wheels

We build the wheel using axle wheel and a hub, attach them together to make the wheel.

5,6) Wheel base and Final Attachment

In order to make the wheel base we used 4 L beams, 3 of different sizes( small) and one large. On the large part of the beam we connect two connector pegs.In the hole between the two connector pegs on each beam we attached an extended black connector peg. Then we attached two small beams to the  pins below the other beams. Then we connect them together in order to finish the robot.

On the second day working on the project we worked on how to make the robot move. This part was very hard fro me because i was having trouble finding the right powers in order of the robot to pass around two rulers that would make 2 ft. first we had to connect the robot with the a computer through ans USB cord. this time the robot could move because also had a battery.i made the robot move though using the Lab view program. Lab view helps to control the robot power.   After many tries i didn’t find the right power in order to make to make the the robot go around two feet. Our task was also to get to get sound into to robot.

During the last class, we used the robots again. The first thing we did was measured the diameter the wheel, and find the circumference of the wheel in meters.  (circumference= p*diameter). The circumference is very helpful because indicates the the distance traveled. For example if the wheel turn was 3 cm and the car moved forward 3 turns then the distance traveled was 3 cm. we also had to calculate the percentage error. Using the program lab view we could control the robot input  data such the time power for both wheels and the computer would give us the number of wheels turned the velocity and the distance. In order to find the percentage error we would subtract the computer distance from our distance, dividing that by our distance plus the computer distance all over two, then multiply that by 100. (My distance was from measuring it with a paper ruler combined together. Overall my percentage error was not that big of a number. I believe that the percentage error might have been caused by my wrong measure of distance since it was a paper ruler.
