First, thanks to Ruby for such an amazing effort.
As to the point about lithium-6 …. Yes, there are lithium-free reactions which show excess heat, no denying that. The gas-phase nanoscale systems of Arata-Zhang, Ahern and others find excess heat with no apparent lithium, no electrical input, and no gamma radiation. BUT these experiments (Arata at least) also found helium-3 in a repeatable ratio and much less helium-4 than with lithium electrolytic work ! This conflict and other divergent results is leading to the only possible conclusion about LENR - that there are more than one type of reaction, possibly many similar but differing reactions - and more than one type of positive outcome. Moreover, many of the experiments of Professor Dash showed excess heat and helium with NO palladium. That’s right, no palladium since titanium was used instead - and moreover Dash felt that titanium was more active than palladium in similar circumstances, BUT he did use lithium electrolyte ! Go figure. This conflicting theoretical and experimental situation is one more reason why Ockham’s razor is no only useless, but harmful to our understanding of the wide range of outcomes which can turn up. Hydrogen, the simplest element in the Universe is also the most complex in its interaction with other elements. From: Ruby > There exist Pd-D systems that make excess heat but do not use Lithium. > Therefore, I conclude, following other scientists' reasoning, that Lithium is > not required for the reaction.
