more on LENR

http://animpossibleinvention.com/2015/10/15/swedish-scientists-claim-lenr-explanation-break-through/

very interesting, as much as I can follow it. An old friend who I know to be a very skilled practical physicist pointed me this way. I have very little doubt that something real is going on here, and we will hear a lot more about it.

So these Swedish guys reverse engineered Rossi's cold fusion box and then patented out from under him. Amazing.

not at all. can you actually read?

Why should he have to read it, having you correct his on-line misconceptions is so much faster.  And more fun.

"can you even read"

Oh fuck you asshole.

I read it. These guys cloned Rossi's experiment and then patented the results. That's what the article says.

What it actually says is that they figured out fairly convincingly *how* and *why* LENR was working, with reference to known and accepted physical theories. They joined the dots. And also figured out how Rossi's method, in terms of electrical resonance, could be made more reliable and (reading between the lines) safer, by using targeted rather than more hit-and-miss resonance.

And in fact, it explicitly says that they *didn't* repeat Rossi's experiment (they started *an* experiment which likely was not a clone, and stopped because of worries over safety.)

But I guess that is all just bit too difficult for the intellectually retarded twat known as "Regular Poster" to comprehend.

Fuck you too asshole. Anyone can make a simple mistake of comprehension, but to repeat it and just start insulting people when your mistake is pointed out takes a tenacious mix of stupidity and arrogance that you seem to have honed to a fine art. Go dig a hole and bury yourself.

so what's the current state of play? various parties trying to confirm/disprove the actual mechanism by experiment?

unfortunately my basic physics is not that great to be able to follow the various arguments through.

I don't understand how a 4-step reaction can be dominant in this reactor: 58Ni -> 62Ni involves the capture of four consecutive neutrons.

How can the end product contain mostly 58Ni and 62Ni, and not the intermediary products with 59, 60 and 61 weight nuclei?

actually, the *really* interesting question about this topic is how long it will take for the energy source it promises to become generally available, how it will be commercialised, and the effect that it will have.

No doubt there is a powerful element that really *doesn't* want a cheap, clean source of energy to become widespread, ubless thay have a big financial part of it - but then others will be willing to put it out there to make money if they *can*. Methinks it is gonna take a bit more than our outdated IP laws to control this one.

Rossi's "revolution" is years past its due date.

Criticism of the Swedish paper: http://link.springer.com/article/10.1140%2Fepjp%2Fi2013-13015-3

"The present article is a critical comment on Widom and Larsens speculations concerning low-energy nuclear reactions (LENR) based on spontaneous collective motion of protons in a room temperature metallic hydride lattice producing oscillating electric fields that renormalize the electron self-energy, adding significantly to the effective electron mass and enabling production of low-energy neutrons. The frequency and mean proton displacement estimated on the basis of neutron scattering from protons in palladium and applied to the Widom and Larsens model of the proton oscillations yield an electron mass enhancement less than one percent, far below the threshold for the proposed neutron production and even farther below the mass enhancement obtained by Widom and Larsen assuming a high charge density. Neutrons are not stopped by the Coulomb barrier, but the energy required for the neutron production is not low."

It failed to convince me yet.

I can more or less follow their story about the interaction between radiation and a plasma state, resulting in a force in non-intuitive directions, but I can't find any explanation on how this will release neutrons from Lithium isotopes.

Secondly I don't understand how those neutrons would be confined to a small reactor volume, while neutrons can travel rather easily through ordinary matter. Why are there no neutrons measured in the Lugano experiment, and why is there no gamma radiation resulting from various reactions of neutrons with other nuclei?

And when they report a sizeable increase in 62Ni, why don't they see at least similar amounts of intermediate transmutation products?

When lithium (or deuterium) plasma is subjected to at- or just-below- resonant-frequency radiation, the Gradient force attracts the neutron out of the nucleus.

Ordinary nuclear reactors have to deal with neutron containment so I imagine that problem has been mostly solved.

How? It still requires several MeV to separate the neutron.
The gradient force operates in the same direction for both negative and positive charges - neutrons do have a charge distribution. How does it separate a neutron from the rest of the nuclei?

I don't expect a super sharp resonance at rather high temperatures, but the resonance has to increase the interaction strength by roughly a million fold to produce enough energy for the separation. I don't see that happening without a better explanation.

The Lugano reactor was just a few centimetres in diameter, and made of aluminium oxide. That wouldn't contain free neutrons.
