Interjection: There is a grammatical inconsistency between "originally used" and "refers".  Since the past tense is correct, "referred" is a better word there.  I'd also like to point out that the part about Prof Jones is a bit unclear.  What experiment did he do that was different from the P/F work?  Did it involve deuterium-saturated metal?  If so, then technically there is little significant difference, today "cold fusion" is basically the description of a proposed explanation for the apparent appearance of heat in experiments that involve deuterium-saturated metal.  Believers, of course, think that the heat is real and the proposal is the correct explanation.
