There is a web cite for this but I lost it. Please help me find this info as I am interested in fusion research.

False, because the binding energy increases steeply till iron and again reduces. So I would require enormous accelerators to transmute the element with Z>20.

I have not worked on stellerators but the anser could be a general one.\nThere is two frequency heating in ICF (inertial confined fusion). if you know stellerators you know what i am talking about.\n\nThere is two frequency heating in ECRIS devices.\n\nWell, there are two resonances possible\n(a) ion cyclotron freq\n(b) electron cycloron freq.\n\nIt could as well be to increase the area of the resonsnt layer. Or maybe heating by inverse landau damping too.\n\nI can only give hints. I must admit, I do'nt know the answer.\n\nPlease email me if you do find an answer

The uses you have identified are using Helium because it is inert and will not chemicaly react with other elements, however, there are potential uses for Helium as fuel, contrary to the other answers. \n\nHelium 3 is considered to be an ideal potential fuel for fusion-reaction power plants. The energy equivalent of Helium 3 compared to steam coal (at $2.5/million BTU) is about $140 million per 100 kg. In other words, it is a quite valuable resource if we are eventually able to utilize fusion reactors. \n\nThe most interesting part of this is that the moon's surface rock contains helium of this light isotope in much higher concentrations than found on earth. It could become economical to obtain He 3 from the moon if we develop fusion reactors as an energy source.

The greatest technological challenge of the 21st century is to meet energy demand in an environmentally sustainable way.  Nuclear energy is a carbon free energy; however, current fission technology leaves a deadly legacy - radioactive waste that is toxic for tens of thousands of years.  To put the energy demands of humans in perspective with nuclear energy, please see the lecture by Nate Lewis (California Institute of Technology).  In 2006, humans are consuming energy at a rate of about 14TW (14 trillion watts).  Using current technology, in order to generate 10TW of energy, we would have to build a new reactor every single day for the next 50 years.  This would be a monumental effort in stupidity and futility.  Furthermore, this would not meet growing energy demand, which is predicted to be ~28TW in the year 2050.  The clearest alternatives are wind energy and solar energy.  Practically, wind energy used globally can potentially provide ~2TW energy, meaning that solar energy is going to be our primary energy source.  The energy that strikes the Earth in 1 hour as sunlight is enough to provide humanity's energy needs for 1 year (~14TW).  However, this energy is diffuse, and we still need to develop low cost, efficient methods to convert solar energy to fuels and electricity. Research is progressing rapidly in this topic.  The world needs to committ massive resources to this right now.  \n\nThe second part of your question relates to cold fusion.  Interestingly, fusion is the source of sunlight, so using solar energy, is in a way, using fusion energy (we don't have to worry about the problems of containment and generating fusion pressures and temperatures).  There are a few research projects around the world that are working on finding useful methods for controlling fusion reactions for energy.  Perhaps the most well known involves a giant room with thousands of high energy lasers that are focused at a pelletized source of fusionable material.  In this scheme, the energy input from the lasers initiates fusion.  This technology is promising, but is far from being economical.  Research efforts should continue.

hydrogen atoms fuse to form helium atoms\n\n2.a high temperature,rather a very high temperature\n\n3.i do not u/stand the question.however if the question is where do you find fusion reaction the answer is in the stars and sun\n\n4.similarities \na.both are nuclear reactions\nb.both generate enormous amount of energy\nc.both produce a energy in the form of heat\nd.both are non conventional sources of energy\ndissimilarities\na.fusion is pollution free\nb.fusion calls for very high temperatures to start the reaction\nc.in fusion lighter nuclei combine to form heavier nuclei.in fission heavier nuclei break \nd.fission is easier to control and produce as compared to fusion

You are exactly right. The energy given to the system when you hit them together was enough energy to break the bonds of the oxide layers on top. The thermal energy of the reaction elevated the electron energy states for a small amount of time, causing them to fall back down to their ground state and giving off some photons...hence the spark.

Wow.  Three responders came up with the same smat*** joke.\n\nCold fusion has been performed in laboratory settings, in a reactor.  So yes, it has been made.  There are no large-scale operations.  That are public.

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
