Introduction And Attention-Getting Story In The 1985 Movie B

Iintroductionaattention Getting Storyin The 1985 Movie Back To The Fu

Introduction A Attention Getting Story In the 1985, movie Back To the Future starring Michael J Fox as Marty McFly and Christopher Lloyd as Doctor Emmet Brown. There is a scene where Marty goes back in time to the year 1955 and is stuck in the past and needs Doctor Brown’s help to go back to 1985. Well in this scene Marty goes to Doc’s house and tells him that he is his only hope to help send him back to 1985. Marty shows a video of Doc about the information of the Delorean’s way to use the time machine and travel thru time. Doc says in the video that the Delorean is “electrical and that he need the 1.21 gig watts of electricity harness the energy needed to go thru time.

Marty tells Doc that all they need is a simple Plutonium, but Doc says that it is impossible to find plutonium in 1955 and that Marty is stuck. Doc tells Marty that the only way to produce 1.21 Gig Watts of electricity is a bolt of lightning. Marty then realizes about the bolt of lightning that is going to strike the clock tower next Saturday night at 10:04 PM. Doc stands up from his chair and says “this is it!†“This is the answer†to harness the bolt of lightning and channel it into the Delorean and easily send Marty back to the future to 1985...

The bolt of lightning is a great source of powerful energy for the Delorean Time Travel Machine but there is another powerful energy that is even greater than the bolt of lightning that Doc Brown figured out to send Marty Back to the Future and it is the sun. MIT’s Dan Nocera and his team have found a new and efficient way to Store Solar Energy in your own home. Dan Nocera has figured out a way of breaking Hydrogen and Oxygen in a catalyst to store a great amount of solar energy from the sun like a charger battery that works continuously without end at night when the sun is not available to power electricity in your house at night without the need of the sun to power the solar panels that need the sun to power the electricity needed in the house. Today...

I will first talk about the origins and history of storing solar energy in Electrochemistry, second the current applications being used today thru trials and experimentation of Storing Solar Energy and lastly the future applications and drawback of Storing Solar Energy)

Origins

History of Solar Energy At Home History Photovoltaic’s and Electrochemistry

a) Photovoltaic cell is the device that converts light directly into electrical energy. (MICROSOFT ENCARTA ENCYCLOPEDIA, 1998) The photovoltaic is what people call solar panels on roofs of buildings developed in 1954 by Bell Laboratories it is made out of silicon. Light strikes a solar cell, positive and negative charges are produced and they are separated and collected, in a process similar to a battery that runs on a Direct Current or (DC). This can be then used directly and stored to serve in a variety of energy needs. (SOLAR ENERGY: TODAY'S TECHNOLOGIES FOR A SUSTAINABLE FUTURE, 1997)

b) Electrochemistry is the process that is the study of a chemical reactions that produce electrical current in water producing currents or voltages. (MICROSOFT ENCARTA ENCYCLOPEDIA, 1998)

Nocera’s New Technology Comes About

How The Oxygen and Hydrogen work

a) Nocera has found a new method of splitting water into hydrogen and oxygen done thru a catalyst of also formally known as electrolysis. (POPULAR MECHANICS, 2008)

b) The catalyst is a mixture of hydrogen and oxygen gases at room temperature that do not explode. The oxygen atoms then react rapidly with hydrogen molecules, colliding with them, forming water, and regenerating the catalyst. The reaction is called the reaction mechanism. (MICROSOFT ENCARTA ENCYCLOPEDIA, 1998)

How the Oxygen and Hydrogen Works

A) Electrolysis

B) Catalyst Cobalt And Phosphorous

a) Hydrogen is a natural gas and it is the most abundant element in the world, many people believe that it is an enormous potential to harness its power as combustion for electricity. (ENERGY ALTERNATIVES, UPDATE, 2008)

b) Fuel Cell

b) Hydrogen Fuel Cell produce no pollution or greenhouse emissions (ENERGY ALTERNATIVES, 2007)

b) Chemical reaction takes place as hydrogen enters the fuel cell, splitting the electrons off the hydrogen molecules to produce electricity that powers the catalyst from the energy from the solar panels. (ENERGY ALTERNATIVES, 2007) (So now that I talked about the origins of the.

Current Applications

Trials

a) Nocera’s Experiment Blueprint

b) Nocera’s Usefulness

a) Photovoltaic panels on a home would provide its residents with electricity during the day, while at the same time splitting water into hydrogen and oxygen. When the sun goes down, a fuel cell would combine the stockpiled molecules to continue to provide power. (POPULAR MECHANICS, 2008)

Future Applications

A) Use of the Solar technology In the Future

a) Funding of Hydrogen Plants

b) The process of finding a clean, cheap and efficient was of making hydrogen would be transformative- which is why the Department of Energy’s Hydrogen program is funding literally dozens of possible ways of doing it. (POPULAR MECHANICS 2008)

b) Hydrogen is versatile enough to be used in other applications such as fuel-cell cars (POPLUAR MECAHNICS, 2008)

Drawbacks of Future Applications

a) Better design of tanks, Hydrogen storage, and cheaper solar panels

b) Build a more efficient version of the experiment trial device and devise a reduction of the physical distance between the two electrodes. (POPULAR MECAHNICS, 2008)

c) Find a convenient, cheapest and most manageable way of storing Hydrogen.

d) Solar Panels need to be cheaper and more efficient. (BOOK, SOLAR POWER, 2010)

Expenses

a) Electrolysis is a complex and expensive process that requires a great amount of energy. (ENERGY ALTERNATIVES, 2007)

Conclusion

A) Now that I have spoken about first the origins of solar energy, secondly the current applications of trials an experiment breakthrough by Nocera and lastly the future applications and possible drawbacks toward the future design of the hydrogen and oxygen tanks connected to the fuel cell and catalyst which is crucial to the major breakthrough that Nocera still needs to accomplish and put into more trails...

B) Remember the story I told you about the scene in Back to The Future when Doctor Emmett Brown figures out how to send Marty McFly back home to 1985 using the bolt of lightning from the clock tower. C) I can relate it to Dan Nocera’s major discovery in the splitting of the hydrogen from the water using electrolysis which was a simple high school experiment done in high school. Nocera states that his experiment was so easy that the discovery Nocera did with the solar energy is that it can use minimum energy from the fuel cell box that is connected to the solar panels in the home using the energy from the sun to make solar power making a new and convenient way toward efficient homes in the future.
