Based on observations of an experienced mechanic, inventor and mechanical draftsman myself. I have determined for myself what may promote and enhance the observed reactions of the LENR process.
Consistant is the need for Nickel (Ni nano powder or solid wire), and to a mechanic as myself it would be desireable to use the Ni solid wire.
Questionable is the percentages and the exact type of "other" powder or solid wire that may be required to enhance and promote a reliable reproducable reaction causing some type of by product power as an end consumer item product.
Consistant is the claim of a matrix evidenced to enhance a reaction that is processed onto the outer surface of the powder mixtures or solid wire.
Constant has been the claim that compressed hydrogen is needed and some claims support a pulsating hydrogen supply enhances the reactions.
Constant is the claim that a hollow copper tube is the best for now fuel chamber or "reflector chamber". This chamber must be sealed to hold hydrogen in a heated environment.
NOTE: At this point there are several constants on claims to cause a reaction of the Ni and compressed hydrogen gas. A hollow copper tube, a means to seal tightly and form a container for nickel powder or solid wire while under pressure and heat,and a means to dispence the heat generated within and on the sealed container.
The variables are processed Ni fuel matrix structures on the surface of the Ni, experimentation will need to include a method to photograph and document multiple surface structures used and results recorded. The actual pressure of hydrogen gas confined within the hollow copper reflector chamber needs to be documented and recorded. The heat on the nano wire induced by electrical current through it's structure needs to be documented and recorded along with the voltages and current needed to sustain the reactions. The heat temperature induced onto the hollow reflector chamber and voltages and current used to maintain reactions from either the nano powder used or the solid wire.
