Prima di passare al pezzo forte [il brevetto Varta, che dovrei tradurre dal tedesco], le suggerisco questa orchestrazione.

Effect of temperature gradient on concentration profile of hydrogen
J. Appl. Phys. 73, 1011 (1993) DOI: 10.1063/1.353318
Abstract
A thermodynamic calculation is conducted to determine the distribution of hydrogen atoms absorbed in a one-dimensional palladium rod, along which a temperature gradient is imposed. The rod is assumed to be completely sealed, so that the total number of the hydrogen atoms is conserved regardless of its thermal conditions. A model calculation based on a zeroth-order interaction model predicts that upon the imposition of the gradient, the hydrogen distribution will significantly change from its initial uniformity. The profile of the redistributed hydrogen CAN BE DISCONTINOUS at ONE point on the rod. The concentration gap developed at this point of temperature T implies that the two-phase region in the palladium hydride phase under the thermal equilibrium is nonexistent under the nonequilibrium condition.

HYDROGEN BY TEMPERATURE GRADIENT EFFECT IN SOLUBLE METAL
Isotopic hydrogen enrichment in a soluble metal is achieved through temperature gradient effects by applying a HEAT SOURCE and a HEAT SINK to two spaced regions of the metal within which isotopic hydrogen atoms are absorbed and enclosed by a diffusion-barrier material. The temperature gradient so created forces the atoms of hydrogen in the hot region to migrate into the cold region, resulting in higher isotopic hydrogen density in the cold region. Discharge of the absorbed isotopic hydrogen is prevented effectively by the diffusion-barrier material.
B) Phonon

METHOD AND APPARATUS FOR ENERGY GENERATION
A method and apparatus for generating energy, which utilizes a SUSTAINED PHONON RESONANCE in a lattice with two or more components. The first component comprises elements having nuclei with quadrupole moment. The second component comprises elements having atomic charge less than the first component, a different phonon spectrum than the first component, and vacancies in the lattice. The phonon resonance within the lattice is sustained at a frequency resonance of 10exp11 to 10exp14 Hz, such that the energy replenishment rate of the phonon resonance is greater than the energy transfer rate to the first component. Creating and sustaining a phonon resonance within the lattice may be accomplished by applying a thermal flux, a photon flux, or microwave radiation along the lattice surface.

Nienhaus, H. et al. Electron-Hole Pair Creation at Ag and Cu Surfaces by Adsorption of Atomic Hydrogen and Deuterium
Phys. Rev. Lett. 82, 2, (1999) DOI:10.1103/PhysRevLett.82.446
... "Although the impingement rate of atomic deuterium was approximately twice as large as for atomic hydrogen, the measured chemicurrent with D exposure was smaller by a factor of 3, i.e., the sensitivity to D is 6 times smaller than to H atoms.
The slight difference in the strengths of H and D metal bonds cannot explain this observed isotope effect.
...............................................
The more relevant mechanism behind the isotope effectis likely to be the deexcitation of highly excited vibrational states formed under chemisorption.
...............................................
Therefore, higher order vibrational relaxation is needed to create hot electrons and holes with sufficient energy to traverse the Schottky barrier. The formation energies of D-Ag and H-Ag bonds are almost identical; however, the vibrational states in the anharmonic D-Ag potential are closer to each other than for H-Ag. Consequently, to create charge carriers with energies above the barrier, the transition between two vibrational levels must be of higher order for the D-Ag than for the H-Ag system. The transition probability decreases with increasing order, so that less electrons or holes with sufficient energy are excited when D instead of H is adsorbed."

Se dovessi scendere in cantina, oltre alla scoperta della "polverina" [che andrebbe ridenominata "pasta del Capitano"], forse avrei anche un altro problema.
Da un'osservazione di Quinlan a Pordenone, sembra che ciò che conta nei cento metri piani siano i decimi di secondo. Se ne può dedurre che l'attivazione è molto specifica rispetto alla temperatura e al gradiente.
Non è difficile immaginare un setup standard per prove veloci, in modo da scremare i candidati e i parametri. Ma per questo serve un altro post.
