Good question.\n\nI can't answer it here, it would take to long, but I suggest you go to this web site:\nhttp://www.iter.org/a/index_use_1.htm\nthen click the link to read more under intro to fusion.\nThen go to fusion as an energy source click read more, and then click how.\n\nThis page does a good job on explaining the basics of a plasma confinement. If you have more specific question feel free to ask.

It is lyophillic sol.\nHydrogen bomb is based on fusion. but to start the fusion the temp required is in millions. So to acquire that temp the fusion is triggered by atom bomb(fission)

Atoms are the building blocks from which matter is formed. Everything around us is made up of atoms. Nuclear energy is contained within the center of the atom in a place known as the nucleus. Particles within the nucleus are held together by a strong force. If a large nucleus is split apart (fission), generous amounts of energy can be liberated. Small nuclei can also be combined (fusion) with an accompanying release of energy. Using this strong force that holds the nucleus together to produce energy is essentially what the field of nuclear power generation is about.\n  In the fission process certain heavy elements, such as some forms of Uranium, are split when a neutron strikes them. When they split, they release energy in the form of kinetic energy (heat) and radiation. The process not only produces energy but also additional neutrons that can be used to fission other Uranium nuclei and start a chain reaction.\n  In fusion, nuclei of light elements are brought together under conditions of high pressure and temperature, causing them to combine and produce new elements and energy.

The process of fusion: 4H  ----->  1He + 2positrons + neutrinoes\nwhich is:                       4p ------>  1AlphaParticle + 2 positrons\n \nie   4 protons fuse together to give an alpha particle.\n\nIt is very unlikely that 4 protons will be in the same vicinity for this reaction to occur.\n\nIn fusion reactors we use deuterium to fuse into helium.\n                  1D  +  1D    -------->   He\nas we only need two particles to collide. (This is much more likely than 4 protons colliding at once. ) \n\nOn the sun we need a way of storing the hydrogen nuclei until we have gathered 4 of them together and they can then split off as the helium nucleus.  The only store you will find on the sun is the collection of slightly heavier atomic nuclei(known by astronomers as metals and meaning any nucleus heavier than helium).\nThere are a number of pathways thought to be available for this process which proceeds through the weak nuclear reaction at a density of 1 or 2 reactions in each cubic metre of the sun. (see stellar physics books for details).  This process is the equivalent to Catalysis in ordinary chemistry.\n\nThis would be hopeless for the generation of energy in a tokamak    so we could not use this process on earth for the generation of electrical power.

The word cryogenics literally means "the production of icy cold"; however the term is used today as a synonym for the low-temperature state. It is not well-defined at what point on the temperature scale refrigeration ends and cryogenics begins. The workers at the National Institute of Standards and Technology at Boulder, Colorado have chosen to consider the field of cryogenics as that involving temperatures below –150 °C (123 K). This is a logical dividing line, since the normal boiling points of the so-called permanent gases (such as helium, hydrogen, neon, nitrogen, oxygen, and normal air) lie below -150 °C while the Freon refrigerants, hydrogen sulfide, and other common refrigerants have boiling points above -150 °C.\n\nRecent research regarding superconductivity at low temperatures has been called cryoelectronics, and the utilization of these sciences is called cryotronics.

fusion is when two elementary particles collide and combine or fuse to make -- even temporarily -- a new particle. In the graphic below, a form of the hydrogen nucleus -- Tritium -- collides with another form of the hydrogen nucleus -- Deuterium -- to form a new particle. (Deuterium and Tritium are isotopes of hydrogen -- a form of water.) The fused particle is not stable, and quickly decays via the split decay mode into a neutron -- moving very fast, i.e., "hot" -- and a helium neucleus -- also know as an "alpha" particle and energy.\nThe radioactive by-products from fission are undeniably bad. They last for tens of thousands of years and can cause untold problems, the worst of which is through terrosists using the waste products for weapons. The fast neutron from fusion can potentially interact with metals a cause them to become radioactive. This process can be minimized by have neutron shielding between the fusion burn and any metals in the reactor. However, the radioactive metals produced -- and any ash from the fusion burn itself -- is a low-level radioactivity that is not considered dangerous, with half-lives in the tens of years. There is no comparison -- radioactive waste from fission is very dangerous, radioactive waste from fusion is not very dangerous.\nIt is hard for most people to understand where this energy comes from, and how much it is. Most people have heard of Einstein's famous equation:\n\nE = mc2\n\nWhen the fusion reactions listed above occur, a small amount of mass disappears. The small amount of mass is converted into a large amount of energy. How much is large? A typical chemical reaction in which hydrogen and oxygen combine to produce water, releases about 1 eV of energy. The fusion process typically releases 1,000,000 times as much energy. Historically, when people talk about the benefits of nuclear fusion, they refer to how much fuel must be burned to equal to each other.\nNuclear fusion takes water, burns it, releases helium (and a small amount of radiation in the form of neutrons), and converts the missing mass into massive amounts of energy.

theorically yes.   The problem is discovering and proving the right theory.   It maybe 500 years but we will eventually solve the cold fusion problem.

A Tokamak is a machine that creates a doughnut-shaped magnetic field; a plasma (basically a bunch of ionized atoms, each with a positive or negative charge) gets trapped in the magnetic field, which we call being “confined” by the field.  By manipulating the magnetic field and the quantity of plasma, extremely high pressures and temperatures can be attained.  For this reason, the Tokamak design is used for fusion research—the hope is that the ions and electrons in the plasma can be squeezed so close together that they will overcome electrical repulsion and fuse together, releasing energy in the process.  (Two positively-charged ions, for example, experience strong electrical forces that push them apart when they get close together, but if they get close enough, nuclear forces can overcome the repulsion, and the ions can fuse to form a larger one.)\n\nFusion happens all the time in extreme environments—the interior of the Sun, for example, where it provides the enrgy for our star to shine—but humans have never managed to achieve controlled fusion.  Instead, we’ve only managed the uncontrolled variety—in the form of hydrogen bombs.\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

The short answer is no. \n\nIn science, it is important that results be repeatable. This is especially true when dealing with some phenomenon like cold fusion which appears to violate all the principles that we understand. \n\nPons and Fleishman and others tried to reproduce the observations, and were unable to do so reliably. A recent review by the Department of Energy of 15 years of research and efforts in the field reached the conclusion that this phenomenon does not exist, or at least cannot be verified.

Cold fusion theory holds that nuclear fusion is possible at room temperature and normal pressure.  If possible, unbelievable amounts of energy could be made available for use without the dangers associated with traditional nuclear fusion.\n\nAs far as I know, no mainstream scientist considers cold fusion to possible.

So, heat of fusion ring any bells?

I can't see anything wrong with the theory, just the slight technical problem that we have not achieved cold fusion!

In Oxford a fusion reactor has been going for many years with a large amount of energy being made. Unfortunately to keep the plasma contained the largest magnetic field generated anywhere has to be maintained and to reach the enormous temperature needed to initiate fusion requires more than ten times the energy extracted. The problems are technical construction rather than theory and with the new international initiative the scientists are confident that a viable fusion reactor can be made in a few decades.
