Abstract

This article is an extension of what presented by our team at 17th International Conference on Cold Fusion, ICCF-17, in Daejon, Korea, in 2012 [1]. It documents the improvements on Constantan-related experiments, started in 2011, in order to study the feasibility of new Nickel based alloys that are able to absorb proper amounts of Hydrogen (H2) and/or Deuterium (D2) and that have, in principle, some possibility to generate anomalous thermal effects at temperatures >100°C. The interest in Ni comes in part because there is the possibility to use also H2 instead of expensive D2. Moreover, cross-comparison of results using H2 instead of D2 can be made and could help the understanding of the phenomena involved (atomic, nuclear, super-chemical origin?) due to the use of such isotopes.

Conclusions
It appears that the commercial Constantan alloy, with the surface deeply modified about geometry (i.e. skeleton
type) and dimensionality of 20-100nm, multi-layers, is a good candidate for anomalous heat production due to:
a. intrinsic low cost of raw materials;
b. simple procedures (i.e. low-cost) of nano-structures growing, as recently developed by our group at
INFN-LNF, Italy;
c. use of Hydrogen.
We observed that such materials have behaviour of “positive feedback” of anomalous power in respect to
temperature increasing.
The experiment showed to be reproducible as experienced both during the Austin (USA) NI Week and ICCF17
Conference (Korea). Several of the results found were similar to what detected by the Japan group (A. Takahashi,
A. Kitamura) in collaboration with Technova (side of Toyota Company), using Ni-Cu alloy dispersed in Zirconia
matrix. Anyway more and systematic work is necessary to elucidate the several open questions, first of all the
stability over time of the anomalous heat generation, safety and a confirmation about reproducibility, not
mentioning the “strange” behaviour using Deuterium gas.
Collaboration of the Community involved in LENR studies is welcomed and a series of attempts to replicate the
experiment is currently performed by different organizations and laboratories worldwide.
The next step will be the use of quartz tube instead of borosilicate, at the moment in use. The quartz will allows
studies at temperatures over 300°C; at the moment it isn’t allowed by borosilicate (1st softening temperature of
typical borosilicate glass is around 300°C).
If positive results will be reconfirmed with the wire made by new procedures (i.e. “second generation” of
preparation), it could be possible to reach “regions” of operation were even

Gee, and I thought everything I needed to know I learned in Kindergarten.

Gee, and I thought everything I needed to know I learned in Kindergarten.

95% of everything you use was learned there.

I wonder which madrassa was obama's kindergarten?

I learned that in my Kindergarten 50 years ago....you must have gone to public school...

Well, I guess that rules out using thermocouples made of Constantan in their experiments.

Hydrogen. As in protium (hydrogen-1). This would be interesting, since it would mean that somehow the diproton (another name for Helium-2) becomes more stable. In stellar fusion, i.e. the p-p chain, the first step would be for the protons to fuse into a diproton. Not stable either way, with either 99.7% or 99.97% (I suspect the latter) with the two protons separating, and the remainder is beta decay to deuterium. This is why the stellar fusion reaction is slow (believe it or not), and this is the critical path in such a reaction. So my question is (if this is indeed working), what is happening to the binding energy of the diproton (calculated to be a negative number), or is there some mechanism overriding this?

Disclosure statement: I am an engineer, not a theoretical physicist.

***There’s a strong chance that such an atomic product would be far more stable when it’s generated inside Condensed Matter rather than in plasma or gaseous state.

[Fred Hayek]

So could more beta decay from diproton to deuteron be dtected? That would be a MAJOR indication of what’s going on. Unless of course we would be looking at a completely different reaction path than what takes place in a stellar core (also considering that there are 4 variations of the p-p chain that we know of).

***I have no idea, but there are career Nuke Physicists on the case and I’m sure they woulda thought of doing that.

It looks from most of the transmutation results that it is alpha decay. For instance:

Recently, the OPEN SOURCE project for LENR detected gamma rays. That means anyone following their recipe should be able to see them. Sure enough, Biberian did... within 48 hours on his experimental bed.

Rossi expressly forbade measuring for gammas during startup. It seems obvious that this is the window to deciphering the reactions, and Rossi has had a 3 year head start on everyone else.

You’re asking the right questions.

"So my question is (if this is indeed working), what is happening to the binding energy of the diproton (calculated to be a negative number), or is there some mechanism overriding this?"

There are "many-body" energy states available in the solid state that are not in the "high-energy plasma" state. Lots and lots of ways to dissipate (or accumulate) energies that are not available to the bare nucleons.

Brillouin postulates that the mechanism is a stepwise addition of protons all the way up to H4, which then collapses to He4 with the 24 MEV deposited into energy sub-levels of the solid matrix rather than showing up as either kinetic energy (moving the He4), or as high-energy gammas. That energy redistributes itself among the many, many different available quantum modes to eventually show up as pure heat.

Note...I'm no kind of physicist either. Chemist with nuke background, so I understand the measurements and can pass judgment on the "goodness" of experimental work....but don't ask me about theory.
