The intensity and density of the triggering energy supplied to activate the nuclear fusion reaction are key factors to produce a smooth and reproducible initiation of the reaction. We previously proposed and numerically analyzed a scheme to provide high-density optical or electromagnetic energy to fusion-fuel materials by lasers and plasmonic field-enhancement effects, to significantly increase the reaction probability [1–6].

Large degrees of field enhancements, or energy focusing, were observed around metal nanoparticles and nanoshells [1], planar metal surfaces [2,3], metal/oxide interfaces [5], sharp metal tips [4], and metal nanogaps [6]. Strikingly, the field enhancement factors for hydrogen-absorbing transition metals, Pd, Ti, and Ni, can surpass those for noble metals in the microwave region [3,4].

This electromagnetic boosting effect may have unconsciously benefited the experiments reported so far, particularly for the electrolysis-type ones, and its active utilization with proper choices of materials, structures, and operating conditions can improve condensed-matter fusion systems further. Gas-phase experimental research in quest of condensed-matter fusion is underway by using multilayered deuterium-containing Pd plates. In our experiment, we in particular directly apply a bias voltage across the Pd sample to provide a current injection through Pd, to stimulate the nuclear reaction by Joule heating, also anticipating strong electrodiffusion or electromigration, in addition to the conventional deuterium diffusion induced by pressure/mass-concentration and thermal gradients.

We installed multiple kinds of lasers in the gas-phase D–Pd reaction system to irradiate the Pd samples coated with noble metal nanoparticles, as energetic stimulation support, potentially with a boosting plasmonic local field-enhancement effect.

We simultaneously observed a sudden temperature increase with an overshoot and a neutron signal. Significantly, we observed a clear signal of substantial-amount 4He generation from the Pd samples as a shoulder peak on the D2 peak, and a possible 3He signal, via in-situ mass spectroscopy [7].

We also observed a sudden burst of these gas species out of the Pd sample. Our results might indicate a certain anomalous nuclear related reaction in the D–Pd system.

Oh goody, it sounds like fusion energy is only 30 years away.

The Plasmonics, with their edgy sound, trace their inspiration back to The Plasmatics.

I saw them on a triple bill with The Dead Kennedys and Black Flag.

My ears rang for days.

Updated No Internal Trolling Rules for FR per Jim Robinson

https://freerepublic.com/focus/f-news/3928396/posts

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

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 science is the goal.

Seems to me that fusion could be achieved on an atom-by-atom basis if you used a super intense magnetic field, 500k gauss, to squeeze two hydrogen atoms together so that they fuse..........................

AFAIK, no macro apparatus exists that allows this to be done. Lattice confinement appears to be the closest tech we have.

Looks to be impossible.........................

[Wonder Warthog]

More or less what I expected, given what I knew of the state of the art.

Nice new research tool, though.

The trick is to treat the math on a one-to-one basis, such as in a Luttinger Liquid and set up a linear Bose-Einstein Condensate.

Hence my Vibrating 1Dimensional Luttinger Liquid Bose-Einstein Condensate [V1DLLBEC] theory.
