Fusion: The Energy of the Future?

     Fusion energy seems to be the most promising energy source of the not-too-distant future. It is safe, it uses an energy supply that is so abundant that it will never run out, it gives off harmless waste, and it produces energy comparable to the Earth's sun! But are there any problems with this hopeful energy source?
What is Nuclear Fusion?
     To understand fusion, it is a good idea to know about fission. This is the splitting of the nuclei of atoms into two or more smaller nuclei by bombarding them with neutrons of low energy. It was discovered in the 1930's in an attempt to make transuranium elements (elements with atomic numbers greater than Uranium that do not exist in nature). They discovered that the nucleus of Uranium-235 breaks apart into two smaller nuclei after absorbing a neutron. This happens because the extra neutron made it unstable. This produces more neutrons that bombard more Uranium nuclei, causing a chain reaction that produces an enormous amount of energy.
     The problem is the nuclear waste that is produces. It is very radioactive and will not become stable for a very long time. Such a harmful substance is a great health concern and needs to be disposed of. Another problem is the energy it needs. It uses an element that is hard to find and which will eventually run out. Also, the reaction cannot be easily stopped and if it can't be stopped, a nuclear meltdown can occur. This is a serious environmental concer...

Hydrogen Fusion is the Future Source of Energy Essay

- Hydrogen Fusion, the Future Source of Energy Abstract The world is currently in an energy crisis with no end in sight. Many technologies can help reduce our dependence on fossil fuels and have the possibility of ending the energy crisis. Hydrogen fusion holds great promise with its no pollution energy output. If more energy can be created than is used to start the fusion process, the energy crisis might become a thing of the past. Over half of the energy used now comes from fossil fuels, which is around 2.77*10^14 KJ in 2003....   [tags: Energy Power Global Warming]

The Future is Bright With Fusion Essay

- With the supply of fossil fuels declining at a predicted rate of about 3% per year since 1971, alternative sources of power are an important issue in the minds of scientists and world leaders alike. While everyone scrambles to find the most effective way to harness solar, wind, and water power, they forget about a form of producing energy that has been researched for 70 years and is only a hair's breadth from being usable (26). Fusion, or the fusing of two atoms, the same power that fuels the sun, could fuel the world’s homes and cars....   [tags: energy, fossil fuels, power]

Essay about Nuclear Fusion: The Path to Limitless Energy

- July 16th, 1945 fusion was artificially created for the first time, this set into motion the idea that fusion was originally wanted for by intellectuals. The idea that humanity could fuse atoms to create energy was the ideal future for fusion and a path to limitless energy. It’s been almost 70 years and humanity has yet to achieve the point of fusion. Humanity has tried for the last 70 years to bring the energy source of the sun to earth and it hasn’t been achieved, but we have created 3 approaches that will hopefully bring the power of the stars to earth within the next 30 years: Cold Fusion, Inertial Confinement, and Magnetic Confinement....   [tags: gamma rays, nuclear physics]

Energy for the Future Essay

- Energy for the Future Energy is often considered to be the world’s most valuable resource. With its vast amount of uses, it is essentially the backbone to the modern world and technology. For many years, the U.S. and other countries around the world have been relying heavily on fossil fuels to meet their energy needs. This dependence has led to a lot of problems not only environmentally but also politically and economically. By using imported oil for our main energy source, the U.S. constantly finds itself struggling with major economic issues if the price starts to go up....   [tags: Energy, World's Most Valuable Resource]

Nuclear Energy Essay

- Nuclear energy now is the world’s mainly useful form of energy. Energy are devolved and have been used from the fossils fuels and are still be used now, but it is not an option to use it in the future. So this turned that we have a nuclear power as the best choice. There are many positives to nuclear energy over fossil fuels such as less global warming effects. At this time nuclear power provides 6% of the world’s energy and about 14% of the world’s electricity. The best part of this nuclear power is generated from the U.S., Japan, and France....   [tags: Energy ]

Nuclear Fusion: The Last “Microfrontier” Essay

- Imagine a world with almost limitless fuel, clean fuel. Envision a society that can harness the same process that powers the sun. Skeptics may say that this is impossible. In fact, an alternate source of energy exists, and so does the process to create it. Nuclear fusion, a process in which the Helium 3 isotope is utilized is the rapture in which the U.S.A., and the world, could produce a great amount of energy as an alternative to petroleum. Whether nuclear fusion produces a substantial amount of energy for the U.S....   [tags: Energy]
