  • Fusion Reactions Before The Plasma
    2,826 words
    Fusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei m...
  • Future's Energy Fusion Energy
    1,041 words
    Fusion Energy By Shaun Thomas Shaun Thomas Mr. Sweet land General Physical Science June 22, 2001 Fusion: Our Future's Energy 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 ...
  • Plasma By Fusion Reactions
    2,517 words
    Why nuclear fusion is so cool... For a fusion reaction to take place, the nuclei, which are positively charged, must have enough kinetic energy to overcome their electrostatic force of repulsion. This can occur either when one nucleus is accelerated to high energies by an accelerating device, or when the energies of both nuclei are raised by the application of very high temperature. The latter method, referred to the application of thermonuclear fusion, is the source of a lot of really cool ener...
  • Actual Fuel Of Fusion Reactions
    820 words
    Nuclear Fusion is constantly present in our solar system. In the core of the sun, Hydrogen is converted to Helium providing enough energy to sustain life on earth. This process occurs at temperatures of 10-15 million degrees Celsius. Scientists are now trying different methods here on Earth to make fusion the next large-scale energy source. The most suitable reaction occurs between the nuclei of the two isotopes of Hydrogen - Deuterium and Tritium. Scientist have already begun to test reactions ...
  • Possible O Waste From Nuclear Energy
    1,173 words
    The Viability of Fission and Fusion For our planet As the global population increases exponentially, having passed six billion in 1999, the world population is expected to be 8.9 billion by the year 2050. The worlds energy consumption will increase by an estimated 54 percent by 2025. Energy demand in the industrialized world is projected to grow 1.2 percent per year. Energy is a critical component of sustained economic growth and improved standards of living. One of the major requirements for su...
  • Fusion As A Source Of Energy
    533 words
    Energy From Nuclear Fusion Nuclear Fusion is the energy-producing process which takes place continuously in the sun and stars. In the core of the sun at temperatures of 10-15 million degrees Celsius, Hydrogen is converted to Helium providing enough energy for us to sustain life on earth. For energy production on earth, different fusion reactions are involved. The most suitable reaction occurs between the nuclei of the two light forms (isotopes) of Hydrogen - Deuterium and Tritium; eventually rea...
  • Use Of Cold Fusion
    1,030 words
    Cold Fusion: The Continuing Mystery In March of 1989, a discovery was made that rocked the scientific world. Stanley Pons and Martin Fleischman had announced that they were able to create and sustain a cold fusion process. After intense media attention, and corresponding interest in future test, the subject seemed to have faded away. Future tests proved inconclusive, and when the quick promise of easy energy didn't materialize, most quickly forgot the subject. Little is said about the continuing...
  • Fission Neutron With An Initial Energy
    1,361 words
    Fission or Fusion I think that right now, fission is the only way that we can get more energy out of a nuclear reaction than we put in. First, the energy per fission is very large. In practical units, the fission of 1 kg (2.2 lb) of uranium-235 releases 18.7 million kilowatt-hours as heat. Second, the fission process initiated by the absorption of one neutron in uranium-235 releases about 2.5 neutrons, on the average, from the split nuclei. The neutrons released in this manner quickly cause the ...
  • Useful Energy From A Fuel
    1,166 words
    In physics, nuclear fusion (a thermonuclear reaction) is a process in which two nuclei join to form a larger nucleus, thereby giving off energy. Nuclear fusion is the energy source which causes stars to "shine", and hydrogen bombs to explode. Any two nuclei can be forced to fuse with enough energy. When lighter nuclei fuse, the resulting nucleon has too many neutrons to be stable, and the neutron is ejected with high energy. Most lighter nuclei will return more energy that it requires to cause t...
  • High Magnetic Fields
    462 words
    The physics of high-temperature, multi-keV, collision less plasmas, usually immersed in a magnetic field of complex geometry, is dominated by the behavior of unique many-body systems in which collective phenomena dominate over rare two-body collisions. These plasmas are usually far from the thermodynamic equilibrium, due to sources of mode-excitation energy that owe their existence to factors including: electrodynamic forces with spatial inhomogeneities (this is the case in magnetic or inertial ...
