There has always been a troubled game between Dewey, IH and Rossi.

We will never know who were the doubles of Clint Eastwood, Lee van Cleef and Eli Wallach but whatever.

That people like Hagelstein, Higgins or Letts get lost more often on LF, it's pretty good for the website.

Colleagues,

A question about COP has been raised and I can answer because these numbers were presented at ICCF21 in Colorado.

I typically apply 300W to keep the reactor around 200C. I then apply a DC discharge to the reactor of 200 mA, 350V or ~ 70 watts.

Labview reduces background heating power to around 230 watts, keeping total input power constant at 300W.

Calibrated XP was reported at 7-10 watts from sub-gram amounts of palladium that had been plated on the inside of the cylindrical reactor. A plot from our paper from ICCF21 is shown below.

When I changed from light hydrogen to heavy hydrogen, thermal power output slowly increased above input power. The maximum separation was about 10W. I consider this of scientific interest but not big enough to be commercial.

If one counts only discharge power, the COP was ~ 1.10.

If one counts total power, then the COP is ~ 1.02 to 1.03.

Both results are outside of the error bars of the calorimeter, which was demonstrated in the data presented at ICCF21.

I'm presently looking for 20-30 watts of excess power.

This information is publicly known but perhaps members of the forum have not taken time to look at the details. I'll be pleased to provide any background information.

Dennis

Bob#2 and Colleagues,

I've conducted LENR experiments since July 10, 1992 and can testify personally that it is a long, slow battle. A "lucha" , as might be said in Spanish (my second language). My latest experiment is #825, starting with #1 in 1992.

Who is in the battle with me? Dennis Cravens has been my research collaborator since 1992. We acknowledged our IH sponsorship at ICCF21 with appreciation. I think Bob also recognized his affiliation with IH at the same conference, as we all three collaborated on our papers. That information is public.

IH sponsors additional researchers in various places; some I know and some I don't. Since that information is not publicly known, I'll not respond further. I will say, that the researchers who work steadily and quietly on LENR under IH sponsorship do so with the same appreciation I have for the financial and spiritual support.

Dennis

Shane and Colleagues,

Arrow? Guess I missed it. I answer direct questions, whether friendly or "snarky".

My lab normally runs 24 x 7, so I don't have much spare time. I'm shut down for a few days, waiting for a vacuum pump repair in Orlando, FL. So, I have spare time to interact with this interesting group.

People I know who made or are making a difference in our field of LENR:

Storms

Celani

Hagelstein

Cravens

Higgins

Biberian

Snoswell

Miley and his group

Hubler

Swartz

Nagel

McKubre

Tanzella

There are others but this is my "off-the-cuff" response. Knowing how this works, I likely left off several

excellent colleagues but I promise they will be on my next response...Dennis

Thank you for direct answer.

So we have an "Industrial Heat Low Energy NUCLEAR Reactor Prototype of scientific interest but not big enough to be commercial".

Do you know if the "environmentally philanthropic leaders" are happy?

Ahlfors and Colleagues,

That is correct. To be commercial, I've read, we need a COP of 3, not 1.10. I'm a long way off from that target but willing to continue the effort for a while longer. I am hopeful that one of us will make a large step-up in power, or at least we will provide enough data to enable a future researcher to make the leap.

Happy? Yes and no.

Yes, I believe IH management is happy with the effort but not satisfied (happy) with the result.

This is also my opinion about my own effort: A in effort, D in results so far.

Dennis

Ohh you have to know Dewey promised me 15000 euros in the past but filled finally your friend Biberian who tell to him that my work was only bullshit.

If sadly you should fail for sure KW will come soon from Biberian side

All of these entities won EU money by my help but the french gravity center managed to get out me from the way.

Gregory,

I helped Dennis Cravens that summer at NI week 2013 because it was held in Austin, Texas, where I live.

The year before (2012), I helped NI coordinate the Celani demo, so I was already familiar with the conference layout.

I thought Cravens' demo was really interesting and consistent with his mental set - rock solid science but fun.

Dr T (Jim Truchard, co-founder of NI) spent a long time at Dennis's booth and asked him if he could make a LENR charger for his Tesla. Dennis said maybe next year!

I also met Dewey at NI week, which led me to collaboration with IH. So, the week was well spent.

Keep enjoying life and science,

Dennis Letts

Cydonia and Colleagues,

I too have been passed over for funding in the LENR field but I didn't take it personally. Politics are found in all human enterprises and LENR is no exception.

I'm not wise enough to know whose work is BS and whose work is worthy; I am wise enough to know what we all should do: keep working!

If you and your work are truly worthy, the continued effort will prove its worth and yours.

This is not idle advice because it worked in my case - I worked mainly on my own for 23 years and eventually IH saw potential in my published experiments. Every day I try to prove that they were right. So, keep thinking, working, and contributing with a positive spirit. This effort may not always work but I know that it has worked at least once. Dennis

Fully agree with you even if sharing these facts made me feel good now yes it will be over..

You know i have had so great sincere exchanges with Bob Higgins at my beginning also now with some LF staff members, to be able to say my future if Lenr future could not be in France for sure !

About you, you can read my comments here, i already considered your work with your partner Cravens very very relevant ( laser experiments for example) , Peter Hagelstein, Bob Higgins for sure too.

Vladimir Dubinko who worked in the same way as you should be well considered too.

Josef Garai gone in the same way as you.

And all Japan teams for sure are relevant too.

So i wish you good luck for your next steps.

Quote from Shane D.

Cravens spheres

Dennis

Respect for your LENR research /effort ..not for the faint of heart

Anyone who talks about their results on LF is braven and not craven..

judging by the arrows directed Mizuno' and others' way

Btw, as is well known Cravens spheres used Samarium/cobalt..

Samarium dates back to Chukanov..

Wyttenbach reported interesting low Kev gamma emissions form Samarium during LENR reactions

The new players from Bangalore... indicated improved xs heat performance with samarium added to their Pd/Ni reactor..as of December 2020

As a class the the lanthanides sit as row beneath the unstable.. fission prone actinides

and have quite a few metastable isotope forms e.g. https://en.wikipedia.org/wiki/Isotopes_of_ytterbium

Are any of the rare earths being investigated further by you or Cravens?

Quote from David Nygren

Thank you and a warm welcome! I'm really glad to see you here, i also appreciate you telling us your version of IH.

I started this site in 2011 with an important purpose, to increase communication in the field to accelerate the development. That's why I'm so grateful to see you post.

David,

I should be thanking you for creating this useful forum. I'm pleased to be here, even if I don't participate often. Thanks for your contributions to LENR. Dennis

Robert,

Cravens has done quite a bit of work with the rare earths. I have done some work with lanthanum, alone and with nickel. I've not seen or heard about any large, surprising XP results. Dennis

Quote from Curbina

Also ask if you have any plans about any scholarly article about the basic science as you understand it.

Curbina and Colleagues,

I don't have any papers planned at the moment. Most of my time is spent worrying about mundane items such as vacuum integrity and solid electrical connections. There are many moving parts and my moving parts are slowing down at age 74.

In 2012 I developed a mathematical model for the dual laser results. Using only experimental data without any data fitting or massage, the model output matched experimental results very closely. In fact too closely, as many colleagues thought I massaged the data to get a close fit. I did not.

The model/equation

The fit

Each data point is a separate experimental result from dual laser stimulation. The active sites were guessed to be vacancies, following the ideas of Hagelstein. The number of vacancies in a metal of known number of lattices can be computed, as was done in the XP equation. The vacancy formation energy (VFE) of 1 eV was guessed at first. Later I was able to compute the VFE because we produced one experiment that had two XP data points at two different temperatures. That procedure can be shown in another post if required. Dennis
