Why is water a friend to the Ni/H reaction and a enemy to the Pd/D reaction.
In nanoplasmonics, an optical box must be formed at the surface of the metal gas interface layer. The metal must not absorb light if the reaction that produces polaritons is to be optimally efficient. Each metal has its own light reflective character.
"Now in his EuroPatent that was revoked it is written:
The transition metal can be selected from the group comprised of: Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Y, Zr, Nb, Pd, Mo, Tc, Ru, Rh, Ag, Cd, Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, lanthanoids, actinoids. Such metals belong to one of the four transition groups"
Good engineering requires that there is a match between the metal selected for use in the reactor and the frequency of light produced or used inside the reactor that is optimally reflected by that metal.
For example. nickel, zirconium, or titanium is best for infrared light. A reactor whose operating temperature is about 600C can use nickel best.
Gold and silver are best used in a reactor that produces visible light. A laser that produces visible light is best used to stimulate these precious metals.
Palladium, platinum and iridium is used best in a reactor that uses ultraviolet light. Light at that wave length is produced by a very high temperature reactor whose operating temperature is about 1500C. Or in the case of laser stimulation(as per Holmlid), a laser in the UV range will product the best stimulation.
It is bad engineering to use noble metals in a low temperature reactor.
If we want to design a reactor that uses a refractory metal like tungsten, we must test that metal to see what type of light is optimally reflected by that metal to see if it is compatible with the heat range of the reactor we intend to design.
Theory establishes the engineering guideline concerning the match of the reflective properties of the metal to the optimal black body temperature range of the reactor being designed. In this regard, the correct theory of LENR is important to direct the proper engineering guidelines used in building a reactor. Random selection of a substrate metal will lead to uncertain reactor behavior.
If the ability to reflect light at a specific frequency is a key parameter in the LENR reaction, any substance that absorbs EMF at that optimum frequency is damaging to the reaction.
The presence of water in the Ni/H reaction which works best in the infrared light frequencies is not damaged by the presence of water in the frequency region of the reaction.
However, in the ultraviolet region of the spectrum where noble metals work best, water absorbs that EMF by a factor of up to 10^^8 times.
The use of palladium in a water based system is problematical because the water in that system will all but stop the LENR reaction. On the other hand, noble metals including palladium in a pure hydrogen gas only gas phase system will work well as shown by Holmlid and the E-Cat X.
When using noble metals, keep oxygen out of the gas mix.
