Yes and no. I get that it is a blessing now, but if people are funded for projects that will fail, that will ultimately cause harm. I cannot be sure these projects will fail, but I fear they will.

We have to wait and see, but so far I see no downside. As an example, the CleanHME and HERMES projects are steadily churning out positive results that perhaps aren’t the “now” solution everyone wants but do confirm undeniably that CF/LENR is real, so warrants funding will keep flowing.

The ARPA-E funding I think will have the same effect, plenty of us disagree with the theoretical path they are choosing, but I am sure they will find results worth keeping the research funding flowing.

Quote from Paradigmnoia

Considering the reaction to Google’s first pass, it seems that much of the negative public relations war on modern, well-funded LENR research is mostly enacted by the LENR enthusiasts themselves.

The PR war I was referring to is the one from mainstream against Cold Fusion. The reaction of the CF community to the Nature article was mixed and completely understandable. I think the assymetry is huge.

Heat Energy Storage Company Azelio goes bust.

Their molten aluminium & Stirling engine technology has not been a success.

I hope the ones to buy it are able to take it to market, 90% efficiency should have been interesting enough, but its a tough market space.

Thanks...

looks like one more attempt to waste money...

I know you have a critic view of this new mainstream approach to LENR, and I, probably many more, understand and agree with your criticism, but from a Public Relations War point of view, as I maintain one has been ongoing since 1989, mainstream acceptance of the field is a blessing.

Primarily he suggests that electromagnetism is a fundamental "super-force" that gives rise to gravitational force.

Wyttenbach also found that gravity is derived from EM.

He does mention Cold Fusion a few times in his publications.

However his overlap with the LENR field as we know it (meaning participation in the ICCFs, Russian Cold Fusion and Micro Ball Lightning conferences, publication as main or co author with other known LENR authors or researchers) is, AFAICT, zero.

Ouch!

I am visiting ENG8's lab - and another test site- at the end of this month, and will report in due course. 'The game's afoot' (Sherlock Holmes)

I hope they don’t NDA you too much.

By reading the patent, written in the necessary opaque way that most patents are written, I can see the electricity is applied to the water with electrodes that probably create arcing and thus “plasma bubbles” or more colloquially sparks, as widely known. This is why I say it’s a plasma arc reactor. As the water is consumed, it can only be that it is transformed into gas. Not much is said about it, one has to infer about. The patent doesn’t make any claims of efficiency at all, and proposes several ways to position the electrodes, which are more or less the obvious thing to do to cover all the bases and doesn’t tell much about which is the best. Is not hard to see how this could have been patented, knowing how patent process works, as this device must certainly get hot, so a heater it is, but also it doesn’t support at all the claims that are put forward about the COP.

Santilli and Richardson patented broadly similar things but they focused in the energy that could be gained by burning the gas obtained as the source of the high COP.

Here is the patent. It’s a plasma arc system, Santilli would be amused.

ETA:

I thought I had been able to download it but my phone refuses to save the file. Let’s see if the link works for you.

Link seems to work fine.

Well, as always such claims are as interesting as the way that they are supported on the public eye is meaningless. I wish they would give more details as how the process happens, from what one can read it seems to be based on some sort of cavitation produced by electricity. Will try to read the granted patent, but it often happens to be of little help when so few technical details are presented.

There’s a number of so called steady state models that imply no expansion and no big bang.

Before the glitch that forced to get back to an earlier version of the database, I had seen Frogfall answering my “while there’s not technical or economic reason for this,” with the reports where the issues of the inadequacies of Hastelloy for long term operation due to the Helium embrittlement and transmutations.

I am well aware of these issues that were in the very reports of the pilot plant at Oak Ridge, what I refer to is that the challenge to find better metallurgy was simply never addressed, it could have been well solved by now if it had.

Hello, thanks for posting this, we are well aware of this publication but we did not have a devoted thread for it, albeit it has been discussed at large in this thread where specific topics of calorimetry are debated The perpetual “is LENR even real” argument thread. starting somewhere around page 60-68.

Perhaps is a good thing you opened this thread.

What are your thoughts on this upcoming Thorium Molten Salt SMR from Copenhagen Atomics??

YouTube Link.

You had me at Thorium.

Jokes apart, knowing that the molten salt thorium reactors were tested extensively at the MW scale and even powered the only atomic powered aircraft ever built, all of this back in the 1960s, and we still don’t see them built massively while there’s not technical or economic reason for this, makes you wonder a lot of things.

Cardone et al did not turn much of their Mercury into gold, tho. But they got a lot of Titanium and Bromine. I wonder if that is economically interesting.

Never understood this obsession with gold.

Anyway, out of having some intellectual fun I have thought of ways to use LENR to get certain elements from treating batches of concentrated solutions of cheaper salts as has been attempted to be patented by Dr. Ryushin Omasa. It requires a liquid based system as one has to circle the solution through one or more selective ion exchange resins that gets the desired product out of the mixture as soon as it is formed, to avoid it getting transmuted further. There are several ion exchange resins that have higher affinity for a reduced type of ions so this could be a way to “mine” stuff from a transmutation broth.

New Paper about succesful replication of Constantan-Deuterium excess heat with COP>3,5 published as a PrePrint by Dimiter Alexandrov.

He also reports higher temperature runs that resulted in explosive bursts of heat release with sudden release of estimated 3K+ Watts. These bursts caused the copper on the constantan to directly evaporate (not melt, so the estimate of the energy released is conservative) and leaving a fine copper residue over the insulators and dielectrics.

Ah, one can feel back in the good old days of succesful reports of Nickel Hydrogen like the ones of Piantelli and Focardi with results like these.

But in this case, Helium is also detected and correlated with the excess energy release. The author does a reasonable effort to rule out chemical / electrical origin. Thermometry is done by optical means, but with reasonable calibration and Nitrogen as Control.

Entering the Hot Case of Cold Nuclear Fusion

Abstract

It is shown in the paper that significant energy release for short time can be achieved in replicable experiments involving interaction of deuterium gas with constantan specimen. The experiments were carried out in a gas chamber where the injected deuterium gas having room temperature interacted with constantan wire heated by externally applied voltage: i) Many replicable experiments were performed at initial temperatures of the constantan wires in range 666C – 681C. The temperatures of the constantan wires began increase at ~8 seconds after the beginning of injection of the deuterium gas and additional increases with 358C – 382C for different experiments were reached at ~30 seconds. The released excess power was in range 183W – 209W and the density of the released excess power was in range ~114W/g – 130W/g. Helium release was observed. ii) Replicable experiments were performed at initial temperature 950C of the constantan wires. In all experiments, explosive evaporations of the wires occurred. The released excess power was greater than 3400W and the density of this power was at least 2280 W/g. The following conclusion can be done - the observed released power was of nuclear origin and it was not of either electrical or chemical origin.

No, the atmosphere has nothing to do with it! The atmosphere protects us from fireballs that measure a few tens of meters in diameter.

I did not mean it as protection, but as eraser and blurrer of the evidence through time.
