Energy localization in bulk hydrides of Pd and Ni crystals manifest itself as discrete breathers (DBs), in which large amplitude atomic motion may result in time-periodic driving of adjacent potential wells occupied by hydrogen ions (protons or deuterons) [1]. This driving has been shown to result in the increase of amplitude and energy of zero-point vibrations (ZPVs) and in broadening of the wave packet [2].

Numerical solution of Schrodinger equation for a particle in a non-stationary double well potential, which is driven time-periodically, shows that the rate of tunnelling of the particle through the potential barrier separating the wells is drastically enhanced by the driving with a resonant frequency ranging from w0 to 2w0, where w0 is the eigenfrequency of the potential well [3].

Based on that, we demonstrate a drastic increase of the D-D or D-H fusion rate with increasing number of modulation periods evaluated in the framework of Schwinger model [4], which takes into account suppression of the Coulomb barrier due to ZPVs, which is further enhanced by the time-periodic driving in DBs.

The resulting macroscopic fusion rate is determined by the concentration and lifetime of DBs, which should be sufficiently large to provide observable fusion rates.

We propose another possibility of time-periodic driving based on reversible phason flips of nanoclusters consisting of 13 Pd or Ni atoms. Phason flip (PF) is a phase transformation of a nanocluster from cuboctahedral (CUBO, 4-fold symmetry) to icosahedral (ICO, 5-fold symmetry) configuration or vice versa. Phason flips were modelled in Pd, Ni and Pd-H clusters consisting of 13, 55, 147, 309 and 561 atoms by LAMMPs techniques.

The smallest clusters of 13 atoms demonstrate reversible PFs at temperatures close to zero K with frequencies lying in THz range, which may be considered as potential drivers of fusion reactions between hydrogen isotopes confined in the clusters. For larger metal clusters, icosahedral symmetry is more energetically favourable then cuboctahedral, but addition of hydrogen affects the final structure of the cluster, and the phase diagram of Pd-H clusters is constructed.

[Kevmo]

for the cold fusion ping list

[grey_whiskers]

Thanks Kevmo.

...what is the width of the barrier the H or D is trying to tunnel through?

Is this fusion of H or D in adjacent sites in the crystal lattice?

Updated No Internal Trolling Rules for FR per Jim Robinson

If someone says stop, then stop. Do not enter onto a thread on a topic you don’t like just to disrupt, rattle cages, poke sticks, insult the regulars, or engage in trolling activities, etc. ~Jim Robinson

This topic has a following, people who wish to learn and discuss the materials presented.

Please refrain from posting anything that doesn’t legitimately address the issue.

Something is going on in this segment of science. There are a considerable number of research groups studying the matter. -Sidebar Moderator

The issue isn’t whether we allow skepticism, it is whether we allow hyperskeptics and skeptopaths to ruin the scientific dialog. Civil discussion of the involved science is desired.

[Kevmo]

I don’t know the width. Everyone suspects H or D fusion, as well as breakoff reactions with the lattice that cause transmutations and fissions.

[grey_whiskers]

Is there such a thing as muon fusion? The lower mass would greatly increase tunneling probabilities, right?

[Kevmo]

Yes, Muon catalyzed fusion.

There are some theories that try to explain the Anomalous Heat Effect by some roundabout muon fusion, that muons are created in more abundance than expected.

I like the Muon Fission Fusion theory, just because it uses muons to explain the primary reaction as well as the secondary one.

Palladium is a key component of fuel cells, which react hydrogen with oxygen to produce electricity, heat, and water. ...................Hmmmmmmm.............. I wonder if this is related?.....................

[Red Badger]

Palladium is kinda expensive....$2658.63 and OUNCE!..............

[Wonder Warthog]

There are several other potential substrates besides palladium. Nickel, titanium, tungsten, and some hydrogen-absorbing compounds. “Hydrogen-absorbing” is a critical feature. I wish more effort was put into investigating tungsten. “Back in the day”, when Langmuir was researching fill gases for light bulbs, he was sure that he was seeing “over unity” values when hydrogen was used as a fill gas.

Unfortunately, Niels Bohr convinced him (on “theoretical” grounds) that “over unity” was impossible. So Langmuir dropped that line of inquiry. Langmuir was a consummate experimentalist....instruments died when Bohr entered a room. I would bet that Langmuir was right.

[Red Badger]

Tungsten is like $40 a TON........................

[Kevmo]

Whoever first comes out with a product, will cause a run in that system. If it’s in Pd, then that price will rise; if in Ni, that price as well. And the price of oil will drop correspondingly.

[Red Badger]

Palladium occupies a very expensive slot on the periodic chart, surrounded by silver, rhodium and platinum.

Silver is the cheapest nearby element.....................

[Wonder Warthog]

"Tungsten is like $40 a TON........................"

Also has the highest melting point of any metal. "If" direct conversion to electricity turns out not to be possible (SAFIRE thinks it will be), and a Carnot process is required, tungsten will yield the highest efficiency of a metal substrate.

[Red Badger]

Maybe THAT’s why they want to get rid of incandescent lightbulbs!..............
