Boron (¹¹B) + protons with the help of CPA lasers.
Probably something similar to what Heinrich Hora is doing and announced for some time.

I had a look at the original website of Heinrich Hora's own HB11 company website. It seems they just launched a new site.

The “avalanche hypothesis” proposed by Heinrich Hora and Georges Miley is very interesting because it could explain many characteristics of LENRs:

« Exceptionally high reaction gains of hydrogen protons measured with the boron isotope 11 are compared with other fusion reactions. This is leading to the conclusion that SECONDARY AVALANCHE REACTIONS are happening »

« Using the initial energy of the α-particle from the HB11 reaction of 2.9 MeV, the first elastic hit transfers 530 keV energy from the α-particle to the boron. After this collision, the α-particle can produce a second hit to boron which is then gaining 492 keV, etc. As known from Nevins et al. (2000), there is an exceptional high fusion cross-section, widely spread, with protons at 550 keV energy, about ten times higher than known from other fusion reactions. The primary produced α-particles are then causing a secondary reaction resulting in three new alphas, etc., »

Fusion energy using avalanche increased boron reactions for block-ignition by ultrahigh power picosecond laser pulses, Laser and Particle Beams (2015), 33, 607–619.

My old hypothesis of "diafluidity" proposing a "chain reaction" mechanism of LENRs caused by "ballistic deuterons" could also be corroborated by some assertions read in communications to ICCF 23.

https://www.researchgate.net/p…_with_English_translation

A few sentences from presentations at ICCF 23:

“The reaction involving deuterium emits part of the nuclear energy as energetic ions having the characteristics of a HYDROGEN ISOTOPE, not helium.”

Edmund Storms, ICCF 23, The Nature of the D+D Fusion Reaction in Palladium and Nickel,

« Initial thin-film electrolytic LENR studies lead to the investigation of ultra-high density regions of deuterium found in voids or dislocation loops in the films Hydrogen “clusters” in these regions were estimated to have roughly 100–1000 atoms with SUPERCONDUCTING PROPERTIES below70 °K as shown by SQUID measurements”

George H Miley and the LENR Lab Team, ICCF 23, Ultra-high Density Cluster Enabled LENR

“The first step in excess heat production in the model is the transfer of the large 24 MeV quantum from the D2/4He transition to produce a reasonably stable highly excited state in a nucleus in the host lattice.”

“Indirect evidence for this comes from low-level energetic particle emission in experiments not producing excess heat. “

Peter L. Hagelstein, Recent progress on phonon-nuclear theoretical models, ICCF 23

“EXCITATION TRANSFER of the 5.5 MeV quantum from the HD/3He transition is considered in the case of light water experiments.”

Peter L. Hagelstein, Recent progress on phonon-nuclear theoretical model, ICCF 23

But the system of double shot with a femtosecond laser igniting the reaction and another laser producing a huge magnetic field by MHD effect is very complicated. It is very interesting as an experimental device, but it is questionable as an industrial energy production system. I suggest using a small, hollow steel sphere filled with borane and setting it into resonant vibration by piezoelectric devices glued to it.

Borane is a liquid which is made of boron and hydrogen, it's a happy for our work.

If this works, we should be able to shut off the power to the piezos, and the sphere should continue to vibrate, and we should recover an electrical voltage at the output. I don't know if you can recover a lot of energy with piezoelectric transducers and there will be worrying problems of cooling.

Therefore, for industrial use, I suggest using a nozzle cavitation system like this type of device that I had tested. (I had published the results at a congress in Russia) (The magnetic field was to be used to increase the cavitation efficiency by MHD effect, that's why there is an electromagnet around the nozzle.)

If my lab hadn't been destroyed, I would have experimented with borane a long time ago.

The energy produced must vaporize some of the borane: for the production of electricity, energy could be recovered by a turbine and an alternator downstream of the cavitator, with a heat exchanger behind.

And the ideal thing, as I had published, would be to use an ionic liquid containing a boron compound in solution, with an heat exchanger downstream. (This way, the focusing of the cavitation energy is not hampered by the vapor in the bubbles.) (No rebound of the shockwave when vapour become supercritical)

Re Marvel...

So far, the company has raised 65 million euros in capital, most recently 35 million euros in February from venture capitalist Earlybird. Marvel Fusion has not yet received state funding, but has won over the well-known industrial partners Thales, Trumpf and Siemens Energy. According to Siemens Energy, renewable energies such as wind power and photovoltaics alone are not enough for a climate-friendly and secure energy supply. That's why the Munich-based company is working with Marvel Fusion, even though the parent company Siemens has long since said goodbye to nuclear technology.

Siemens Energy sees two advantages in laser-based fusion technology: it produces very little radioactive waste and can be ready for the market faster than other approaches. In the partnership, Siemens Energy will primarily be responsible for converting fusion energy into electricity. According to its own information, the Swabian laser specialist Trumpf also firmly believes that laser-driven nuclear fusion “will be an essential component of future energy supply”, as a company spokesman says. Trumpf is to develop special lasers for nuclear fusion. However, the engineers do not expect devices suitable for use in power plants until 2040. Trumpf also does not want to commit itself to Marvel Fusion as the only potential partner.

Nice building. Cool lasers. Best of luck to them.

A different MARVEL... This is micro reactor (fission) out of Idaho National Laboratory.

If CMNS energy technologies enter the market by 2024 this MARVEL will be ended before the project gets past the initial prototype stage.

Idaho National Laboratory is one of the national laboratories of the United States Department of Energy and is managed by the Battelle Energy Alliance. While the laboratory does other research, historically it has been involved with nuclear research.

Microreactor Applications Research Validation and Evaluation Project (MARVEL) Integrating Microreactors with End-User Applications

The U.S. Department of Energy (DOE) Microreactor Program supports research and development (R&D) of technologies related to the development, demonstration, and deployment of very small, factory-fabricated, transportable

reactors to provide power and heat for decentralized generation in civilian, industrial, and defense energy sectors.

Led by Idaho National Laboratory (INL), the program conducts both fundamental and applied R&D to reduce the risks associated with new technology performance and manufacturing readiness of microreactors. The intent is to ensure that microreactor concepts can

be licensed and deployed by commercial entities to meet specific use case requirements.

What is the Microreactor Applications

Research Validation and Evaluation

(MARVEL) Project?

Under the auspices of the DOE Microreactor Program, INL is developing a nuclear microreactor applications test bed to perform research and development on various operational features of microreactors and enable improved integration of microreactors with end-user applications.

Development of the MARVEL test bed provides an opportunity to establish and exercise key capabilities to support future microreactor demonstrations.

Remember this ANS Quote

"The Google team, which included researchers from Massachusetts Institute of Technology, the University of British Columbia, and Lawrence Berkeley National Laboratory, found no evidence of classic Pons-Fleischmann–style cold fusion. It did, however, find evidence of the larger umbrella category of LENRs—suggesting that nuclear reactions may be possible in locally hot sites in otherwise room-temperature metals."

(U.S. Navy Researchers Dive into Cold Fusion Debate Mar 24, 2021, ANS Nuclear Cafe)

The Google team...sure...I am not impressed. In what world do you assemble a research team to pioneer in a difficult subject by ensuring everyone has absolutely no experience whatsoever in the field? So, if you want to build a steam locomotive first you have to reinvent the wheel? Who could have known such a research team would produce underwhelming results? We could have done real research with the money they spent.

Maybe in a world where all those before have not been able to move the technology, and decided instead to try a new approach?

IMO, no one should be critical of those who at least tried, no matter their means. We are all on the same team and should support each other. Google did not have to do what they did BTW. I, and everyone who believes in LENR, should give them credit for stepping up to the plate and trying.

And while there is an argument their results were underwhelming, it is becoming more clear they actually made some progress.

Not sure what you mean also by "done real research with the money they spent"? What real research would you have done differently?

Shane, your points are well taken. Bold of Google to do anything in the field! Perhaps exposing all those bright young minds to LENR will bear fruit in the long run after all. If I sound critical it is because disappointment might have been avoided if the team had been peppered with a few of the reliable old guard of LENR. That being said, my apologies are in order. The research was real, even if it was not as successful as hoped. I had good reason to expect something wonderful.

They were. Lots of disinformation out there.

i touched a little bit this Lenr Google project,

and i share Shane's thoughts about that.

Even i'm disagree for example for an EU project as HERMES, indeed they done as for Googles project too what they want with their own money.

About Google's team they were presumptious however so many for last 30 years were also presumptious since a while.

The desire to do well, the deep idea that we hold the real truth, we all fell into that one day at least.
