LENRIA Corporation
ARPA-E Workshop on Low-Energy Nuclear Reactions
21-22 October 2021
Goals & Outline of this Presentation:
Provide background on LENR Experiments
Give a few examples of promising approaches to repeatable LENR experiments that could be understandable and acceptable to the broader scientific community
Provide a brief summary of the entire LENR field.
Fundamental Considerations for any LENR Experiments:
What was done? Equipment, Materials and Protocols
What was found in the original & subsequent experiments ?
Experimental Approaches to LENR: The Reactants, How to Join Them and What to Measure
Materials Methods Measurements
Pd & Alloys Ni & Alloys Other Materials Sources of H or D Excess Nuclear Prompt Low Energy D (or P) P (or D) P or D Means of Loading: Heat Products Radiations Emissions
The two most common combinations of reactants are Pd with D and Ni with H. The two most common ways to get the Protons or Deuterons are electrolysis of water and dissociation of hot H2 or D2 gases.
Materials change during LENR experiments due to loading. 3 LENR experiments require bringing together hydrogen isotopes and materials.
Adequate concentrations are needed for sufficient reactions for measurements. Reaction mechanisms require interactions of reactants, which require motions.
Challenges to Highlighting Particular Experiments: What factors are most important in identifying “repeatable LENR experiments that could be understandable and acceptable to the broader scientific community”
Multiple factors are important, including:
The complexity of experiments is a factor.
The types of measurements play a major role.
The magnitude of produced LENR thermal power is important both scientifically and practically.
The types of nuclear products that are measured provide important information on reactions.
Particular Experiments Worth Detailed Attention: Arata and Zhang: “Double Structure Cathode” Electrochemical Experiments Measured both LENR heat and nuclear products
Swartz: Electrochemical Loading of Palladium Coil PHUSORTM Dry Loaded Two-Terminal NANORTM Careful Calibration and LENR heat measurements Storms: Electrochemical Loading of Compacted Powders. Temperature-dependent LENR heat measurements.
Transmutation Experiments. Helium, which is correlated with heat generation. Production of Other Elements There are MANY other worthwhile experiments to consider !
Methods for Calorimetry during LENR Experiments: Thermal Barrier: [Temperature] Heat Flow Calorimeters
No Thermal Barrier: Seebeck [Voltage] Water [Ordinary Temperatures]
Mass Flow Calorimeters Oil [Elevated Temperatures]
Calorimeters are NOT Sensitive: 1 mW is limit of good LENR calorimeters. 1 mW =3 x 108 24 MeV reactions/second
Noise limits the performance of LENR calorimeters
“Double Structure Cathode” from Arata and Zhang 30 kJ/hr = 8.4 W 100 days
High purity Deuterium gas at high pressures

Methods for Measuring Reaction Products in LENR Experiments: new elements during and after an experiment
Need to measure elements present before the experiment
Many Analytical Methods are Available: https://en.wikipedia.org/wiki/List_of_chemical_analysis_methods https://en.wikipedia.org/wiki/List_of_materials_analysis_methods
These web sites list over one hundred methods, many relevant to measurement of LENR products. Only about two dozen methods have been use for the study of LENR reaction products.
The detection limits of various analytical methods vary widely. They depend on the features of the method and the instruments. Composition (and Structure) of materials varies in space and time.
Noise limits the performance of Analytical Methods.
Helium Production in LENR Experiments In ordinary (hot) D-D fusion, one in ten million events produces a He-4 and a 23.8 MeV gamma ray. Helium is Produced in LENR Experiments AND Correlated with the Production of Energy in the Same Experiments:

Summary on Experimental Status of LENR
Diverse global experiments for one-third of a century have shown LENR occur and they do, indeed, involve nuclear reactions.
The experiments pose a challenging scientific problem, and indicate significant practical promise at the time when new clean energy sources are needed.
Past experiments have suffered from being uncoordinated, and from lack of funding for needed parametric studies and for the employment of available modern tools.
The results have suffered from ignore-ance by the broader scientific community due to the bad reputation of the field and lack of funding.
The single most important claim from one-third of a century of experimental research on LENR is:
Nuclear reactions can be caused by use of chemical energies.
Thermal energy is measured that cannot be explained by known chemical reactions:
2000 eV/atom and 50 kW/cm3
Products that cannot come from chemical reactions: Tritium, Helium and Many Other Nuclei.
Exciting New Science
Experimental Results Suggest Practical Promise:
Getting MeV by using eV enables high energy gains, and high energy gains portend low-cost power.
Experiments have shown that LENR have other promising features:
High power densities. Lack of dangerous radiation. Little radioactive waste. No greenhouse gas emission.
Potential Clean Energy
Potential LENR Advantages and Impacts
High Energy Gains User Friendly (like HVAC Systems)
Sustained (“Burning”) Reactions Adequately Low Capital Cost
Production of Heat and Low Operational Cost
Generation of Electricity Easy Operation and Refueling
Opportunities for Optimization Long Times Between Refueling
Potentially Safe Operation Long Operational Lifetime
Fail Safe Operation seems Possible Abundant Hydrogen Fuel
Likely Radiation Safety Abundant Nickel or Other Fuels
No Input Radioactive Materials Low Cost Power: 5 cents.…$100+
Adequately Safe Input Chemicals Distributed LENR Generators
Possibly Beneficial Waste Relief for the Power Grid
Negligible Radioactive Waste Fewer Large Power Stations
No Chemically Dangerous Waste Easy Disposal of LENR Generators
No Greenhouse Gas Emission Rapid Adoption Once on the Market
Less Environmental Degradation Many Potential Applications
Possible Silent Operation Proliferation of Electricity
High Energy Density Lifestyle Improvements
Lightweight Systems Better Connectivity and Education
Portable Energy Systems Production of Clean Water
Scalability (Diverse Power Levels) Historical Health Improvements
Information on LENR
The International Conferences on Condensed Matter Nuclear Science have been a primary global forum for the field over the decades since Fleischmann and Pons announced their ability to produce excess heat energy. The meetings were initially known as the International Conference on Cold Fusion, with the abbreviation of ICCF, which has been retained. The primary topic of the field came to be called Low Energy Nuclear Reactions (LENR), although there are about twenty other names for the subject

Oh , you mean this One here below?
Thank you for this set of links , great stuff. I see that they actually pulled off a fusion instant with the Joint European Torus (JET) near Oxford, UK recently.

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. Such FReepers who persist in polluting these threads have been asked to leave, and we are asking that they open their own threads if they have comments.

"Converting from a PDF/Powerpoint file to something that can be posted on FR is quite challenging. The format gets messed up in the wildest ways. If anyone has suggestions better than using https://convertio.co/ I'm all ears..."
and hand input (type it in) in HTML.
***No thanks. Been there, done that.
You used to be able to just “view source” and then post the HTML source but I think those days are gone. Especially going from PDF or Powerpoint to HTML.
(NOT PDF) In HTML, while on the website, right click, and you should be able to choose th view source. Some website have a block on that, somehow.. but if you hit F12, an editor will pop up with HTML and CSS. It is tricky, and takes getting used to.
Not sure if that would help you..
I went to the original file
https://arpa-e.energy.gov/sites/default/files/2021LENR_workshop_Nagel.pdf
converted it to HTML
and tried to “view source” but it is a very complicated panel that comes up. I can’t even view source. But I can view the file...
Now I’m glad I saved your page and two of the articles. Perhaps a copyright issue?
My husband used to try to follow posting guidelines to the letter, and there were times when his posts were pulled in what appeared to be an arbitrary manner and without explanation. Mystifying.
