The Keystone XL Pipeline

 

When the President initially vetoed the TransCanada Company’s proposed $7 billion Keystone XL Tar Sands Pipeline, it meant that 830,000 barrels of oil a day would not travel from Alberta, Canada to the Gulf’s oil refineries.  Though a politically popular decision with environmentalists,  it was very unpopular with construction unions, as well as most Americans.

 

In my opinion one of the main pros I can see is that the Keystone pipeline is not simply about oil, but also about thousands of jobs (estimated to be 20,000  construction and 100,000 indirect jobs) and significant effects on the economy.  It’s therefore important to analyze the President’s decision.

 

One of the main cons I’ve found is about the big contamination the Keystone Pipeline could produce.

-Cons:

 

-Tar Sands oil is the dirtiest oil on the planet

 

Producing synthetic crude oil from tar sands generates three times the global warming pollution of conventional crude production. Extracting tar sands bitumen – a low-grade, high-sulfur crude oil that must be extensively refined to be turned into fuel – uses vast amounts of energy and water.

 

-Canadian tar sands oil would be exported

 

Keystone XL would have diverted Canadian oil from refineries in the Midwest to the Gulf Coast where it could be refined and exported. Many of these refineries are in Foreign Trade Zones where oil may be exported to international buyers without paying U.S. taxes.

 

The facts reveal this pipeline was never in America’s national interest. Clean energy and fuel efficiency is the path forward for economic and energy security in America – not another tar sands pipeline. By rejecting the Keystone XL pipeline, President Obama is helping move America down a cleaner, safer path.

-Pros:

 

-In the other hand we have the pros of the Keystone XL Pipeline, and they are mainly about economy:

 

A policy study shows that Keystone XL will generate approximately $1.8 billion in economic activity during construction in Nebraska alone. The study also found that Keystone XL will have a substantial tax impact, generating $134.6 million in state and local levies.

 

Here I’ll enclose a pair of videos defending this huge pipeline:

Brainstorming Session

 

The first day, professor Greg Sonek chose the working groups, we have to present our final experiment. It has to be related to something we have seen in class.

 

The next day, after a wonderful experiment done in class, my colleagues and I initiated the group brainstorm about our final project. The truth is that the three of us got a lot of interesting ideas, but not all were valid. We had to find an experiment that we could perform in class, while allowing us to take a series of measurements about what we were showing.

 

Some of the ideas we had was to create our own stirling heat engine or use the power of steam of a pressure pot to make a series of measurements. However we decided to test the efficiency of different types of light bulbs. For this we’ll need several things: a hand crank generator, different types of bulbs, a DC power supply and a voltmeter.

So, what we decided is to build our own hand crank generator, then we connect the different light bulbs to it one by one. We turn the crank generator and we see how easy it is to light up the light bulbs. To make the experiment measurable, we replace the crank generator for a DC power supply. To find out the voltage needed to turn the bulbs on, we’ll use a voltmeter, so we can calculate the efficiency.

 

 

The President’s Climate Action Plan

Ultimately, we need a comprehensive energy and climate policy that prices carbon pollution and levels the playing field for renewable sources of energy that are not degrading our climate and planet. But given that USA has an intransigent Congress (the current House Science Committee leadership continues to deny even the existence of human-caused climate change), the president has been forced to turn to executive actions. His call for carbon emission limits on all coal-fired power plants, not just newly built plants, is a bold step forward. It will go some way to stemming our growing carbon emissions and the impact they are having on our climate.

 

Finally, the president spelled out promising ways forward to introduce greater incentives for renewable, non-carbon based energy; reduce energy usage/improve energy efficiency; and adapt to those climate change impacts which are already locked in and unavoidable.

The Museum of Science

 

 

I’ll start the blog saying it is the third time I’ve visited the museum this year.

 

The Museum of Science is an outstanding science museum! Albeit it’s geared towards kids, there is a lot of things for adults as well.

 

They have a number of various areas covered in this museum. Everything from animals, to the scietific method, trail and error, electricity, experimentation, advancements in technology, etc. There were a million items happening here simultaneously.

 

This museum had several interactive items for kids and adults alike. Some are obviously more child oriented but allow for competition between kids or even between adults(like we did…)

I don’t agree with some of the hypothesis that the museum declared as fact. For example the politics of global warming. There is not yet confirmation that this is a man made thing and not just a normal cyclical thing. Perhaps if we had more data than it would be solid but with scientists on both sides of this, it would be interesting to see both viewpoints covered, wouldnt it?

 

 

In the link below, you can see an exhibition of large-scale color photographs about the climate change in the world:

One of the most helpful things I’ve seen in the museum, related to our class, was about learning how wind turbines generate electricity. There is a really interesting exhibit about this theme.

In the link below you can learn a little more about this show named “Catching the Wind”:

Pandora’s Promise

 

 

Pandora’s Promise is an amazing documentary with an excellent technical bill that could be described quite simply as pro-nuclear, and exposes to the viewer to heavy doses of confusion and, why not say, propaganda, (even with that it’s still a great job). Maintained at all times within the limits of the excessive, gets raise serious doubts about the pros and cons of this form of power so feared by the general public and probably so unknown. It starts with the shocking proposal that a small cube of radioactive material can produce incredible amounts of energy.

 

The documentary, which was shown in the past Sundance Festival, begins by showing the testimony of American Ecologists recognized locally with career in anti-nuclear activist who openly declare themselves in favor of this misunderstood and mysterious form of energy. In its reasoning, always maintaining his absolute conviction in defense of middle-atmosphere conclude that this is the only power that can truly compete against fossil threatening while supplying a world suffers an increasing need for energy will likely double in the coming years.

 

Pandora’s Promise gets surprise and shudder us when goes with these witnesses to places like Fukushima or Chernobyl. These brave incursions are made with “Geiger counter” in hand, allowing us to compare directly the levels of residual radiation from these places marked by fate with many other parts of the world, filmed with the same pattern for more visual impact. Great sequence that shows that there is natural radiation everywhere, more at higher altitudes, and the levels do not seem to have an important relationship with sites affected by nuclear accidents like Chernobyl, 58 countries with nuclear reactors as France or natural beaches in Brazil. A simple but very striking exercise.

If a statement that makes this documentary proves absolutely certain is that there is a serious general ignorance about nuclear energy, real use, and even their potential dangers. Audience and documentary are discovering surprising facts together on this important issue. With the help of interesting archive images and computer simulations, Pandora’s Promise tries to explain that nuclear power and the atomic bomb are different things, still today the burning of coal not only produces practically all the energy we consume, but it is still the fastest growing despite being the most toxic; renewable energies depend on the gas to compensate for their lack of regularity, and many other amazing facts that seek to change the view that the public has about atomic energy.

 

The documental provides interesting interviews that show us scientists that when they began to develop this energy were just little more than environmental dreamers who augured that all would work today with this clean and “renewable” energy, and also shows us that behind the campaign of fear and the media rejection are the companies which are living on fossil fuels, and finally points out the American political class as the main cause of failure of nuclear energy.

 

We can believe what they say or not, but at least it worths spending time entertaining with Pandora’s Promise, a documentary, also interesting, is notably well made and fun just for the fact of selling an idea contrary to all established.

 

 

MIT Nuclear Reactor Laboratory

 

 

The MITR-II is the major experimental facility of the NRL, is a heavy-water reflected, light-water cooled and moderated nuclear reactor that utilizes flat, plate-type, finned, aluminum-clad fuel elements.

 

Thanks to the website, we know that the MIT Research Reactor is used primarily for the production of neutrons. To put the reactor into operation, the control blades are raised very slowly. As they absorb fewer and fewer neutrons, more and more neutrons are available to cause the splitting of uranium nuclei, until finally enough neutrons are being released to sustain a chain reaction.

The MITR research program encompasses most aspects of neutron science and engineering including nuclear medicine. Some of these activities are:

 

-Boron neutron capture therapy

-Radiation synovectomy

-Neutron activation analysis for the identification of trace elements and isotope ratios in geological specimens

-Fission engineering

-Materials testing

-Training

-Neutron transmutation doping of silicon

 

The MITR is one of only six facilities in the world to be engaged in patient trials for the use of boron neutron capture therapy (BNCT) to treat both brain tumors and skin cancer. The MITR fission converter beam is the first to be designed for BNCT.

 

 

 

The MIT Nuclear Reactor Laboratory offers raining, research, and educational opportunities with laboratory courses of MIT undergraduate and graduate-level, research projects as part of Undergraduate Research Opportunity Program (UROP), student reactor operator training program, senior and graduate thesis research projects, and  Independent Activity Courses.

 

The MIT-NRL also maintains a successful public outreach program. The educational and outreach activities include:

 

MIT provides tours and lectures to the general public that help people who doesn’t study there to know more about this nuclear reactor (~1500 individuals per year). So our class has been lucky for the chance given.
