Fusion Power, can it ever work?
The idea of the originator of merger began towards the beginning of the 20th degree Celsius and research into it is continuing up until today. On earth it is modelled on the method in which stars obtain their cleverness, from the fusing of nuclei. As these reactions occur a little mass is lost and this is released as heat. This reaction follows Einsteins most famous traffic pattern E = MC2. As the value of mass is multiplied by the speed of light squared, a slender change in mass results in a ample meat of expertness being pull ind. So far the most effective methods of recreating union on earth have been by using gigantic chambers surrounded by electromagnets and by heating the reaction mixture generally enthalpy entryWe live in a society in which elan vital, in all its dramatis personaes, is at a premium. The bell of household electricity does not only hurt your back pocket more every year, unless with each kilowatt-hour that is used we are damaging the environment t hat until now has sustained us. In this modern world it is becoming increasingly important that we find a practical and sustainable new form of skill and soon.One possibility is that we harness the source of energy that has been powering the stars over the aeons, the energy locked away inside hydrogen atoms, the energy known as Fusion Power. Fusion often known as thermonuclear fusion is defined as the union of atomic nuclei to form a heavier nucleus with the release of energy1. The important dower of this definition is the fact that these unions release energy. The other important facts ab extinct fusion are that it uses hydrogen, the most bulky element in our universe and produces the harmless element helium. Therefore no pollution is produced during the process of fusion. registerYou could say that the history of atomic Fusion began with the big bang as in its aftermath exit began to form clumps due to gravitational attraction forming the very first stars the matter of whic h then began to undergo fusion. as yet on earth, the history of fusion began in with a number of scientific discoveries near the beginning of the 20th century. In these years, scientists began to learn more and more about the structure of the atom. This was also the time in which the speculation of relativity and the formula E=MC2 was proposed by one Albert Einstein. These discoveries and the war with Germany lead to scientists developing the first Nuclear Fission bombs and later the Hydrogen or Nuclear Fusion bomb. With these scientists began to realise the theoretically massive amounts of energy contained within atoms and began to realise that with proper control these could be harnessed and made to deliver power that could be used to generate electricity ( a good excuse, while also providing a source of radioactive matter for bombing far away nations)2. Before it is possible to condone how fusion works is, it is necessary to take a closer look at the atom.The Atom and Matter Before it is possible to explain the mechanism of nuclear fusion, it is necessary to explain the background. The atom as you probably know consists of a nucleus, with a cloud of electrons surrounding it. The nucleus further consists of protons and neutrons.Matter can usually be set in motion in three forms with which people are familiar, these being Solid, Liquid and Gas. However there is a forth form of matter, known to scientists as plasma. Plasma is formed when gases are alter to extremely high temperatures, like those found in the cores of stars. The electrons separate from the protons and neutrons in the gas atoms and the mixture of charged particles move around separately at high speeds forming the plasma. This plasma cannot be maintained by normal chemical reactions, as the amounts of energy they produce are not sufficient instead, the process of fusion occurs.Nuclear FusionIn laymans terms what occurs during fusion is that the nuclei of two hydrogen nuclei are accelerated together with sufficient speed or kinetic energy to overcome the repulsion between the positively charged particles. When the two nuclei touch, the force of gravity takes over and holds them together forming a new nucleolus containing two protons. This means that the nucleus is no longer that of hydrogen exclusively is instead that of helium. During this process a little of the mass of the two hydrogen nuclei will be lost.The long physicist Albert Einstein was mentioned earlier in this document as was his most famous formula E = MC2. The E in this formula stands for energy, while the M stands for mass and the C stands for the speed of light or 3108.This formula shows that there is a direct correlation between energy and mass. As I express earlier during the fusion of the two hydrogen nuclei a little mass is lost, this is because it is converted into energy. As the formula, shows the amount of mass is multiplied by the speed of light squared or 91016 a massive number. This means that if a tiny amount of mass is lost a massive amount of energy is released, enough to maintain the massive temperatures inside the core of stars. It is this energy that scientists are trying to bring rase to earth, in the hope that this will provide a clean energy for future generations.How Fusion is carried out on EarthAs you may realise heating hydrogen to temperatures equivalent to those of the core of the sun on earth is a little bit tricky. This is because there are no materials that we have competent of withstanding these temperatures and containing the plasma that would be formed. One way to do this is to surround the hydrogen or lithium hydride with fissile material and carry out nuclear fission in order to generate heat for the nuclear fusion as is done in Hydrogen bombs. This is however unpractical for the generation of electricity as the power station and the surrounding country would probably no longer exist. So instead physicists have assay to generate the plasma and use a strong magnetic field to hold it. The plasma itself is heated by a number of powerful lasers, which are able to heat it to near the required temperatures. To go through it has however been impossible to sustain this generation of plasma and contain the heat. It has also not been possible to actually generate any energy from the fusion of the hydrogen atoms.
