I am not so sure to say “cold fusion” is not occurring anywhere. The Pons Fleischmann experiment has been duplicated over 14,000 times, yet it is not understood, nor is it predictable and commercial. There is something happening and people are working on it. Sixty Minutes did the a show on an Israeli company that has made strides in the field.
It may come to nothing, but there needs to be more scientific work done to explain it.
I see that "replicated over 14,000 times" claim a lot, but cannot find any reliable documentation of successful replication claims. Surely, if cold fusion occurred and was replicatable, there would be publications in peer-reviewed journals reporting these replications. Instead, cold fusion seems to fall into the "pathological science" category--where a handful of scientists/aficionados just cannot bear to let go of a hypothesis, no matter how little evidence there is in support of the hypothesis.
Physical law indicates that there is a very high energy barrier to fusion, which is why it must take place at such high temperatures. Cold fusion would be a godsend--a way to achieve energy-producing fusion, while having only to worry about the radioactive emissions (which we have a lot of collective experience in shielding), and not about attempting to contain a reaction occurring at thousands of degrees would be great.
