Cold Fusion, here we go again...

[Michel Van]

1989 happen short life hype about cheap Fusion
about reaction of Heavy water with Palladium

Now NASA strikes again with "Lattice Confinement Fusion"
instead of Heavy water with Palladium, they use a metal lattice, loaded with deuterium fuel
This lattice is expose with hard x-ray (or Gamma Ray)
Idea behind this is that in metal lattice the deuterium atoms are million times closer as in fusion plasma
and under Hard radiation can happen Fusion at room temperature

Nuclear fusion reactions in deuterated metals

Nuclear fusion reactions of D-D are examined in an environment comprised of high density cold fuel embedded in metal lattices in which a small fuel portion is activated by hot neutrons. Such an environment provides for enhanced screening of the Coulomb barrier due to conduction and shell...

Novel nuclear reactions observed in bremsstrahlung-irradiated deuterated metals

$d$-D nuclear fusion events were observed in an electron-screened, deuterated metal lattice by reacting cold deuterons with hot deuterons $({d}^{*})$ produced by elastically scattered neutrons originating from bremsstrahlung photodissociation (where ``d'' and ``D'' denote $^{2}\mathrm{H}$)...

Hm, if I understood correctly it's more like "compressed fusion", than "cold fusion". Also quite dubious, but at least here is a plausible theory how it MIGHT work first.

This looks nice. previous "iterations" on cold fusion i read so far didnt elaborate how one can actually start the reactor in the first place.

I read some about this lattice confinement, and it actually seems promising. Of course, I'm not a physicist, but I was unable to find any particularly glaring mistake, that would draw attention. And the whole idea - to use metal crystal lattice to compress deuterium atoms close to each other - actually looks pretty... graceful.

"Cold Fusion" is "Low Energy Nuclear Reactions" and the reason it's "cold" is because it's happening at 4500 degrees, so it's a lot more useful, easy to work with and miniaturize.
