  Fusion   (Site not responding. Last check: 2007-11-03)
Nuclear fusion, nature's power souce, offers a bright light for the future being based on the fusion of heavy isotopes of Hydrogen, elements that are abundant in the solar core and which are extractable from sea water on Earth.
Fusion is not without its ecological dangers though but the avoidance of fossil fuel burning, impossibility of explosion, and lack of weapon grade material by-products, means that it appears to offer a safer and cleaner current alternative.
Nuclear fusion of light elements is the energy source which causes stars to shine and hydrogen bombs to explode.

 The Energy Planet :: Nuclear Fusion :: English
Nuclear Fusion and Nuclear Fission are two very different forms of energy and it is important to not confuse the two.
Nuclear Fission is a splitting of atoms, while nuclear fusion is the fusing, or joining of atoms.
Fusion is the oldest form of energy generation, being used in the original source of energy, the sun.

But the fusion of lighter nuclei, which creates a heavier nucleus and a free neutron, will generally release more energy than it took to force them together — an exothermic process that can produce self-sustaining reactions.
A third confinement principle is to apply a rapid pulse of energy to a large part of the surface of a pellet of fusion fuel, causing it to simultaneously "implode" and heat to very high pressure and temperature.
The ions undergoing fusion in many systems will essentially never occur alone but will be mixed with electrons that neutralize the ions' electrical charge and form a plasma.

 The Environmental Literacy Council - Nuclear Energy
Nuclear reactors produce energy from uranium through an atomic fission reaction — that is, radioactive atoms are split apart and the energy that is released in that fission is harnessed to produce heat and electricity.
Nuclear fusion involves fusing two atoms of hydrogen together in order to form one atom of helium.
Fusion is an overall safer process and produces waste that is not as problematic as fission wastes are.

 Tokamak Summary
In 1968, at the third IAEA International Conference on Plasma Physics and Controlled Nuclear Fusion Research at Novosibirsk, Russian scientists announced that they had achieved electron temperatures of over 1000 eV in a tokamak device (1 electronvolt is equal to 11605 kelvins).
The tokamak continues to be the most promising device for generating net power from nuclear fusion, reflected in the design of the next generation ITER device.
In the early days of fusion research, the devices used were variations on the Z-pinch, which aimed to use a poloidal field to contain the plasma.

 Nuclear Fusion
In a hydrogen bomb, two isotopes of hydrogen, deuterium and tritium are fused to form a nucleus of helium and a neutron.
Unlike nuclear fission, there is no limit on the amount of the fusion that can occur.
The neutron bomb differs from standard nuclear weapons insofar as its primary lethal effects come from the radiation damage caused by the neutrons it emits.

 Nuclear Fusion Reactor
Nuclear fusion is one which has recently been embraced even by some of the world's major power brokers.
Fusion is the process of atoms combining at extraordinarily high temperatures that not only provides the energy of the sun and stars but also gives hydrogen bombs their enormous power.
Fusion reactors, by contrast, would produce minimal waste that would be radioactive for a much shorter period, backers say.

 Fusion Pulse drive
The nuclear fusion-pulse rocket is powered by continuous explosions of small amounts of fnuclear fusion material, and propelled by deflecting the explosive forces with reflectors.
Fusion pulse came into its own with the mass-production of ultra-light ultrastrong materials like Buckyfibre and other forms of Diamondoid, during the middle and late Interplanetary age.
Today, Fusion Pulse, like continous Fusion drive, is a cheap and robust, relatively low tech system that does not require advanced AI piloting, and hence is widely used by a number of biotist, anthropist, and human supremacist clades and factions throughiout the galaxy.

 Cold Fusion
Fusion is the reaction responsible for the power of hydrogen bombs and the magnitude of the energy released by the sun.
A serious drawback to fusion reactions as they are normally understood is the exorbitant amount of energy required to start the reaction, making it hard to contain and sustain the reaction, thus impractical given the current level of our technology, even as of the year 2000.

JET, the Joint European Torus Torus, is a tokamak tokamak and is the largest and most powerful nuclear fusion nuclear fusion reactor yet built.
JET was later equipped with remote handling facilities to cope with the radioactivity produced by deuterium deuterium-tritium tritium fuel, which is the fuel proposed for the first generation of fusion power plants.
For most of 2004 it will be shutdown for a series of major upgrades increasing total available heating power to over 40MW, enabling further studies relevant to the development of ITER ITER to be undertaken.

Scientists recommend the extraction of deuterium from sea water and the ignition of nuclear fusion of this element in temperatures as high as 100 million degrees Celsius.
In nuclear fusion, deuterium abstracted from one kilogram of sea water will be able to produce as much energy as that of 300 liters of gasoline.
Invention of a facility that can withstand the temperature of 100 million degrees Celsius and control deuterium and atomic fusion to ensure steady and continuous energy output equals to invention of an artificial sun, which can provide infinite and clean energy like the sun, as sea water is virtually inexhaustible.
