JET. "Nuclear Fusion Basics." 21 Nov. 2005
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 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 heavy forms (isotopes) of Hydrogen - Deuterium (D) and Tritium (T); eventually reactions involving just Deuterium or Deuterium and Helium (3He) may be used.
At the temperatures required for the D-T fusion reaction - over 100 Million deg. C - the fuel has changed its state from gas to PLASMA. In a plasma, the electrons have been separated from the atomic nuclei (usually called the "ions"). Understanding plasma required major developments in physics. Plasmas are now used widely in industry, especially for semi-conductor manufacture.
This reasource gave lots of good qouteable facts.
Freudenrich, Craig. "How Nuclear Fusion Reactors Work." Howstuffworks.com. 21 Nov. 2005
Fusion reactors have been getting a lot of press recently because they offer some major advantages over other power sources. They will use abundant sources of fuel, they will not leak radiation above normal background levels and they will produce less radioactive waste than current fission reactors.
Nobody has put the technology into practice yet, but working reactors aren't actually that far off. Fusion reactors are now in experimental stages at several laboratories in the United States and around the world.
This reasource makes things easy to understand, and provides links to other resources.

Abundant Fuel Supply
The major fuel, deuterium, may be readily extracted from ordinary water, which is available to all nations. The surface waters of the earth contain more than 10 million million tons of deuterium, an essentially inexhaustible supply. The tritium required would be produced from lithium, which is available from land deposits or from sea water which contains thousands of years' supply. The world-wide availability of these materials would thus eliminate international tensions caused by imbalance in fuel supply. Comparison of Coal and Fusion Power Plants

No Risk of a Nuclear Accident
The amounts of deuterium and tritium in the fusion reaction zone will be so small that a large uncontrolled release of energy would be impossible. In the event of a malfunction, the plasma would strike the walls of its containment vessel and cool.
No Air Pollution
Since no fossil fuels are used, there will be no release of chemical combustion products because they will not be produced.
No High-level Nuclear Waste
Similarly, there will be no fission products formed to present a handling and disposal problem. Radioactivity will be produced by neutrons interacting with the reactor structure, but careful materials selection is expected to minimize the handling and ultimate disposal of activated materials.
No Generation of Weapons Material
Another significant advantage is that the materials and by-products of fusion are not suitable for use in the production of nuclear weapons.
Summary
The abundance of raw materials, their wide distribution, and the environmental acceptability of fusion are augmented by the expectation that fusion energy will be an economical source of electricity generation.

ITER. "ITER." International Thermonuclear Experimental Reactor. 21 Nov. 2005
ITER is the experimental step between today’s studies of plasma physics and tomorrow's electricity-producing fusion power plants.
It is based around a hydrogen plasma torus operating at over 100 million °C, and will produce 500 MW of fusion power.
It is an international project involving The People's Republic of China, the European Union and Switzerland (represented by Euratom), Japan, the Republic of Korea, the Russian Federation, and the United States of America, under the auspices of the IAEA.
It is technically ready to start construction and the first plasma operation is expected in 2016.
ITER is to be constructed in Europe, at Cadarache, near Aix-en-Provence, France.
This site basically gave a whole bunch of information about ITER, the international collaberation to create a sustained reaction.
Savinar, Matt. "Life after the Oil Crash." ??-??-2004. 21 Nov. 2005
Oil will not just "run out" because all oil production follows a bell curve. This is true whether we're talking about an individual field, a country, or on the planet as a whole.
Oil is increasingly plentiful on the upslope of the bell curve, increasingly scarce and expensive on the down slope. The peak of the curve coincides with the point at which the endowment of oil has been 50 percent depleted. Once the peak is passed, oil production begins to go down while cost begins to go up.
In practical and considerably oversimplified terms, this means that if 2000 was the year of global Peak Oil, worldwide oil production in the year 2020 will be the same as it was in 1980. However, the world’s population in 2020 will be both much larger (approximately twice) and much more industrialized (oil-dependent) than it was in 1980. Consequently, worldwide demand for oil will outpace worldwide production of oil by a significant margin. As a result, the price will skyrocket, oil-dependant economies will crumble, and resource wars will explode.
I consider this site to be propoganda. All that I took from it were the bare facts, not the persuasive stuff.
Peterson, F. "Inertial Fusion Energy: A Tutorial on the Technology and Economics." 21 Nov. 2005
In inertial confinement fusion, small B-B-size hollow spherical capsules, most likely made of plastic, are filled at high pressure with an equal mixture of deuterium and tritium, and then chilled to cryogenic temperatures, so that the D-T gas freezes as a thin, solid coating on the inside of the capsule wall. Suspended by a thin plastic film at the center of a metal cavity called a hohlraum, these spherical capsules can be injected into the center of a target chamber. There, in a few billionths of a second, lasers, or beams of high-energy heavy ions as pictured in Fig. 1 above, can be used to heat the interior of the hohlraum cavity to temperatures several hundred times the temperature of the sun, vaporizing the surface of the plastic shell into an extremely high pressure plasma. Alternatively, direct-drive targets have no hohlraum, and lasers heat the capsule surface directly.
The capsule, transformed into vaporized plasma, reaches pressures of hundreds of millions of atmospheres. As the plasma expands outward like rocket exhaust, it accelerates the thin layer of D-T radially inward, to velocities of 300 to 400 kilometers per second. The residual D-T gas from the center of the capsule, heated by the denser D-T that surrounds and compresses it, reaches peak temperatures over 100 million degrees Celsius, sufficient to ignite a propagating fusion reaction. Just as a match can light firewood, this hot spot ignites a fusion burn wave that propagates out into the denser D-T. By releasing seventy or more times the energy originally needed to compress and heat the fuel, this dynamic process provides the basis for generating inertial fusion energy. The second chapter of these notes, "How ICF targets work," discusses in greater detail the physical processes that occur in ICF targets, and the issues related to manufacturing inexpensive targets and injecting them with high precision into target chambers.
Gave lots of good information about inertial confidement. Probibally my biggest source on the subject.
