Please list those here, at least topically. I have about 5 in mind, perhaps there is an overlap, or I may have missed a couple. Thanks in advance.
Happy to see you again here Longview.
Sorry maybe for a misunderstanding because by "triggering" i would say things needed to DO Lenr not necessarily to trigger.
I should answer to you indirectly because actually we always try to replicate Rossi's work following what we have understood recently.
As i said in the past , hydrogen isn't essential for every transmutation, first point, for example,no kinetic energy anymore, no very high pressure to compress nuclei both.
Therefore a need to put nuclei at a certain distance from each other, what we can do for example by electrolysis. it's close to few hundred bars even so.
However, this pressure could be therefore converted into kinetic energy but it would be far from needs of conventional nuclear field.
A frequency with a wavelength in the infrared... I think I am close 6 ......now...
