Nuclear Fusion

Nuclear Fusion

            The necessity of energy made the man look forward in the search for new forms to produce it. Nowadays people uses energy without thinking of the future. We just waste it charging our phones, cooking our food or driving our cars to go to places. One day this kind of actions will stop because we use an energy that will end. Almost everything needs energy and the actual forms of energy are not endless, actually the human race is desperate for one source of infinite energy, so we need a solution, an option, we need the Nuclear Fusion.
            First of all, what is nuclear fusion? It occurs when two atoms nucleus collide to create another atom nucleus, heavier than others atoms used in its creation. In this process of “creation” a great quantity of energy is released in various types like heat or light. The simplest example of nuclear fusion is the Sun. The heat that we feel every day coming from the sun is because of the nuclear fusion that it produced, and this energy is released in form of heat and gives us the gift of life.
            Why is nuclear fusion good? For any type of energy you need to provide the “fuel” to make it happen. For our current most used form of energy we use fossil fuel that is not infinity. For the simplest nuclear fusion the fuels are two isotopes of hydrogen and the hydrogen is most abundant element in the word. The fossil energy pollutes the air, the nuclear fusion energy does not pollute anything. The nuclear fusion energy does not release radiation to the environment, different of the nuclear fission energy that does a great damage. The nuclear fusion reactors are big but not huge, so in comparison to the main energy in Brazil that is hydroelectric, the nuclear fusion is much better because you do not need a huge space to build and place a reactor. These facts show the why nuclear fusion energy is a perfect energy.
            Another question, why is not nuclear fusion used as an energy source? We have a few reasons to answer this question: It is not really safe because we do not know how to control it; the people are afraid of fission energy, so they feel the same thing about fusion energy; it is hard to keep the conditions to the nuclear fusion occurs like high temperature and pressure; the reactor are not perfect to sustain so many heat and pressure; to start a reactor need a huge amount of money and the big companies of oil not allow scientists to do that.
            How does the nuclear fusion reactor produces energy? The produce of energy is based in production of water vapor. When the water is boiling the water vapor are produced, so we heat the water. The general process is simple, heat the water and make the water vapor pass by some propellers, the water vapor make the propellers move and its movement produce energy. After that it is almost the same process in others types of energy produce like wind energy, the difference is that nuclear fusion energy will be producing energy all the time.
            When will we be able to use nuclear fusion energy? The expected date is just speculation. Some scientists  that we will never be able to produce a significant amount of nuclear energy, but the most of science community believes that in just a few years we can have cars made by nuclear fusion reactors. The best expectation of good results is for 2020, they do not know the reason why this year but the expectation is big.
            In conclusion the superiority of nuclear fusion energy is obvious. You can compare with any other type of energy and the result will be the same: Nuclear Fusion energy is the right choice. If compared with fossil energy, wind energy and hydroelectric energy, nuclear fusion energy is better to environment, to human healthy and to secure our future. There is no mistake.

            To end this discussion I just need to say that the current used energy is bad to the Earth and our environmental system. They will kill the planet with us inside. We need to look forward and trust in the power of science. Science has been helping us since the beginning of the life. Nuclear fusion is the future of the Earth, the future of the humanity, the future of life.
