Cold Fusion?

This report quickly turns into a single theory and what seems to work with these reactions: heavy electron, not observed elsewhere ??? and SPP, possible theory, which was chosen because with more apparent physical coherence, after the initial physical hypotheses (heavy electron, no more seen than the other theories).
So not convincing, does not necessarily require a laser, and no more observed proton resonance;

All the theories proposed (much more than in this report) are dubious, with inconsistencies.

In addition, this report seems to favor a theory for influencing NASA, in a direction to provide funding.

Finally, PPS, and other possible imaginations, are a means of achieving a nano particle accelerator which once at a few keV, can cross the Coulomb electrostatic barrier and reach the nucleus for nuclear reactions.
A nano particle accelerator is much easier with a laser (large electric field possible), electric discharges, than with milder means.
In general, lots are drawn, hence non-reproducible results, as this report says, but making this reproducible is not easy (nanotechnology) and the report does not offer anything.

develop your nano accelerators a bit and tell us what the SPP initiaes mean

[dedeleco]

tell us what the SPP initiaes mean

it is written in the pdf of the NASA oral report if we read it carefully:

Plasmon Polaritons surface

magic word, as said, these are polariton plasmons waves (strong coupling between ions, phonons, electrons and photons) on the surface of the grains !!

A hyper-complex set where you can imagine almost everything you want, as the concentration of the energy of lots of atoms on a single atom, created like a rascal wave on the surface of the sea, which would pass through the Coulomb barrier.

Surface plasmon (not SPPs), occur as light induced packets of electrical charges that collectively oscillate at the surfaces of metals at optical frequencies. Under specific conditions, the light that radiates the object (incident light) couples with the surface plasmons to create self-sustaining, propagating electromagnetic waves known as surface plasmon polaritons (SPPs). Once launched, the SPPs ripple along the metal-dielectric interface and do not stray from this narrow path. Compared with the incident light that triggered the transformation, the SPPs can be much shorter in wavelength.

In other words, when SPs couple with a photon, the resulting hybridized excitation is called a surface plasmon polariton (SPP). This SPP can propagate along the surface of a metal until energy is lost either via absorption in the metal or radiation into free-space.
Nanoplasmonics
Nanofabricated systems that exploit SPPs demonstrate potential for designing and controlling the propagation of light in matter. In particular, SPPs can be used to channel light efficiently into nanometer scale volumes, leading to direct modification of resonate frequency dispersion properties (substantially shrinking the wavelength of light and the speed of light pulses for example), as well as field enhancements suitable for enabling strong interactions with nonlinear materials. The resulting enhanced sensitivity of light to external parameters (for example, an electric field or the dielectric applied constant of an adsorbed molecular layer) shows great promise for applications in sensing and switching.

Current research is focused on the design, fabrication, and experimental characterization of novel components for measurement and communications based on nanoscale plasmonic effects. These devices include ultra-compact plasmonic interferometers for applications such as biosensing, optical positioning and optical switching, as well as the individual building blocks (plasmon source, waveguide and detector) needed to integrate a high-bandwidth, infrared-frequency plasmonic communications link on a silicon chip.

In addition to building functional devices based on SPPs, it appears feasible to exploit the dispersion characteristics of SPPs traveling in confined metallo-dielectric spaces to create photonic materials with artificially tailored bulk optical characteristics, otherwise known as metamaterials. [4]
