Very nice paper from a time when printers didn't existed yet
In the same way, i like reading again some first investigations what could not be necessary unrelevant, as this Vigier's thoughts.
The history of cold fusion is a remarkable story at the confluence of science and sociology. This paper - written from an arts perspective - shows how tricky it is to reach scientific conclusions from contested data.
Yet - all major science advance comes eventually from a better theoretical understanding that turns messy anomalous contested data into stuff that is understood.
BTW - just to burnish my skeptical credentials - note that the converse is not true. Messy anomalous contested data may be just that, a sociological artifact or even just a sign of looking for things that capture the imagination but cannot be disproved or proved. Many examples of that - e.g. evidence for bigfoot.
I am highlighting the paragraph below in the conclusions. I agree that the early CF debate was frames as physicists vs chemists. I agree also that initially physicists were predisposed against seeing CF as nuclear, whereas chemists more open. I disagree that the continued negativity of most physicists was unreasonable.
Initially - F&P claimed conventional nuclear fusion (with expected energy and particle byproducts) from an electrochemical reaction. Physicists reacted with extreme skepticism because that seemed unlikely - the Coulomb barrier (CB) argument.
That morphed over time as expected particle (and reactant) product measurements proved elusive - and belief in any such measurements was not helped by initial false positive errors in measuring particles!
Fusion without the expected products from known reactions seemed to physicists even less likely. The no-expected-product argument (NEP).
Now, both CB and NEP arguments can be got round. Branching rates for nuclear reactions could be affected greatly by novel reaction mechanisms so that we have unexpected results in both areas is not as surprising as it might otherwise seem. But, both arguments require something new and surprising to overcome the skepticism. Of the two - the CB argument is the easiest to get round.
For me, that remains the case now. I see this playing out in two ways:
(1) LENR positives stay elusive. The sign for that would be that decades-old data remains the "best quality evidence". Funding now, post google-guys-effort (for which incidentally we should be thanking Rossi) is large enough to generate new better results and advance the filed.
(2) The hypotheses needed for arguments that counter CB and NEP get filled in. They have been formulated and new more informative experiments are being done. The sign of these experiments is that what you get out is more self-validating than "heat/no heat" or "neutrons/no neutrons". It could be LENR-adjacent work: for example looking at how reaction rates as evidenced by products are characterised from input energy or something else. Or looking theoretically or via simulation and how reaction branching rations change. It could be other stuff where new physics unrelated to LENR leads to new nuclear reaction possibilities. Or even something LENR-contradictory where new physics leads to non-nuclear-reaction high energy and power density power production (e.g. hydrinos, weird Rydberg states, weird alternatives to QM). I have never seen any LENR-contradictory stuff yet that looks remotely close to explaining the corpus of LENR evidence - and in fact it all looks like woo-woo at the moment.
So - we get papers like #245, #246. #247 above (Ahlfors) which do not mention LENR but are LENR-adjacent and could lead to undeniable LENR evidence.
The conclusion of the arts degree dissertation below misses an important scientific point and simplifies what is scientific progress. It also misses the point about LENR.
Both quantum physics and relativity emerged from a maelstrom of previous novel theories [1,2] trying to explain anomalous data. The anomalies were undisputed, out there all over the place, and clear. How to explain them required radical new ideas and was not clear. But both special relativity and quantum mechanics were theories that had many less successful but building-block theoretical precursors. They (SR and QM) were accepted in the end because they explained so many disparate observations with better economy than alternatives and made new predictions that turned out right.

In the case of LENR things are a bit different. We do not have anomalies cropping up all over physics from assorted non-LENR research. Nor do we have significant LENR quantitative predictions validated by LENR experiments. (the few cases here are contentious). Nor do we have (yet) a comprehensive theory that emerges from prior less successful theories addressing the anomalies.
The point is that the groundbreaking "major" physics discoveries have build on a lot of previous work both experiment (clear anomalies found by assorted people without any theoretical axe to grind) and theory (those anomalies attract interest and theoreticians try to find solutions - even though before the final synthesis these are partial).
If that analogy was to apply to LENR then it is work like the papers linked by Ahlfors that are needed first - before any successful "LENR discovery". And the discovery would be some major shift in our understanding of (most probably) nuclear reaction rates or (less probably) something woo-woo due to lack of coherent anomalies giving it support.
At the moment the LENR anomalies are comparable to the situation before QM or relativity - where things were not well understood. But then the anomalies stood as real without the need for a hypothesised explanatory theory. They were things that needed explaining. Too much of the LENR corpus is backwards-looking: LENR is hypothesised and indirect evidence that seems to support it is highlighted.
It is - as a matter of science - nor surprising that this type of evidence is less convincing than the anomalies that led after many years of incremental theory generation to the success of relativity or quantum mechanics.
Happy Christmas & New Year everyone.
