There are a couple of meanings. One of them is in reference to a particular claim; another is a more general (and much more widely accepted) term. First the particular: Two scientists in the 1980s, Pons and Fleischmann at the University of Utah, claimed to get excess heat out of a simple little electrochemical cell. Replicating their experiment seemed impossible and the current orthodoxy says they were deluded by temperature measurements that were done poorly. (Temperature measurements are frequently more difficult than they appear!)

They actually had a temperature spike which they 'assumed' to be from fusion in their equipment. Post analysis of the water in their cell indicated the presence of aluminum hydroxide. The problem is, there was no aluminum included in their experiment.

A laboratory assistant, tasked to watch the experiment in the evenings, later admitted he had accidentally dropped a small piece of aluminum foil into the cell. Aluminum introduced into an electrolysis cell will rapidly oxidize, generating excess heat and releasing large amounts of hydrogen gas. Their neutron detector just happened to record a neutron from spontaneous fission from natural uranium deposits in the earth at the same time the temperature spike occurred. These two errors together led them to believe they had discovered fusion at room temperature.

Nevertheless, this experiment has given rise to a whole field of scammers and true believers. A whole universe of cold-fusion literature exists on the internet. The other, more general, use of the term is to describe any kind of fusion that occurs at temperatures below millions of Kelvin. One such is muon-catalyzed fusion; there is little to no doubt in the scientific community that muon-catalyzed fusion is indeed fusion, nor that it can occur at room temperature or even below. It really is "cold fusion," though it isn't likely to ever be a power source unless an efficient low-energy way of producing muons is discovered. Unfortunately, due to the sensationalism of the Utah claim and the failure of a great many attempts to replicate the original Utah results, many people attempting to conduct serious research in the field are often dismissed out of hand (and this tends to lead towards a reluctance of such researchers to criticize other claims for fear of giving skeptics even more reason to dismiss it out of hand). What is cold fusion? : The answer above is incorrect. Cold fusion has been reproduced by over 1000 respected scientists in over 100,000 experiments. In 1989 alone, there are 90 referenced articles by different groups around the world that confirmed Pons and Fleichmens results. Only one MIT study claimed they proved Cold fusion does not work. It was found 4 years later that the MIT group falsified results and the groups was censured by the academic review board. Why would MIT and other Labs like MIT do this. They have Tokamak Hot fusion reactor, which is an enormous expense and big business. When Cold fusion exceeds thermodynamic break even, they will put hot fusion out of business, which I predict will never work.

What is the cold fusion?

"Cold fusion" refers to fusion at (or near) room temperature, rather than the millions of degrees that are normally required. This has not been achieved so far - at least, not to any significant degree.

There is one song that is called "So Cold" by Breaking Benjamin and there is also another song named "Cold" that is by Crossfade.


Does nuclear fusion occur at a low temperature?

No, normally it occurs at temperatures of millions of degrees. It does occur at room temperature, but not in significant amount; any possible practical use of "cold fusion" is, so far, speculation.

What is the major disadvantage of using nuclear fusion?

We don't have nuclear fusion reactors. We have not been able to sustain a controlled fusion reaction for more than a brief moment in time, and of more than a small amount of power. Only the Sun and stars have controlled fusion reactions, and Hydrogen bombs have uncontrolled fusion reactions. The problem is in maintaining the extremely high temperature and pressure required to sustain a fusion reaction, while at the same time containing the plasma that results from it. It is so hot that no container will hold it. We can build magnetic "bottles" so to speak, but the enormous flux required to do that requires super magnets, and that requires super-conductors and super-cold temperatures. Placing a super-hot plasma flow within the boundaries of a super-cold magnet is just not something we have accomplished yet. We are working on it, but, barring any stupendous discovery, I think controlled fusion reactors are at least 50 or a 100 years away.
