McKubre, M. C. H. (2015). Cold fusion: comments on the state of scientific proof. Current Science, 108(4), 495-498.
THE question under discussion is whether the phenomenon known as cold fusion has been proven to be existent or non-existent. This is an important question, for if real, the possibility exists that cold fusion might become a meaningful primary energy source with few of the disadvantages associated with the power sources that we have available to us today. One expects science to be able to rationally investigate and determine answers to questions such as this. Having investigated this phenomenon almost full time for the past 25 years, I will state my preliminary conclusion up front and then proceed with a more nuanced discussion. Whatever it is and by whatever underlying mechanism it proceeds, the accumulated evidence strongly supports the conclusion that nuclear effects take place in condensed matter states by pathways, at rates and with products different from those of the simple, isolated, pairwise nuclear reactions that we are so familiar with in free space (i.e. two-body interactions). The implications of this statement are profound and we will proceed with caution on the basis of validation of the envisaged new science.
