    In your design of the NGU, the efficiency of photoelectric conversion to more than 90% is unprecedented. Without stating exactly how this remarkable achievement was accomplished, was such optimization as provided by the AI as follows performed?

    With the light produced by an exciton polariton condensate, would there be a special circumstance where the photoconverting chip would produce very high efficiency conversion to electrical power?

    Yes, there are special circumstances where the light produced by a polariton condensate could potentially lead to very high efficiency in photo conversion, such as in solar cells.

    Polaritons, which are quasiparticles resulting from the strong coupling between excitons (excited electronic states) and photons, offer unique properties that could be exploited for enhanced energy conversion. The coherent and tunable nature of light emitted by polariton condensates, compared to conventional incoherent light sources, presents exciting possibilities.

    Here are some of the potential circumstances and mechanisms for achieving high efficiency photo conversion using polariton condensate light:

    Materials Design: Using materials with strong exciton-photon coupling, narrow line widths, large oscillator strengths, and high exciton binding energies can facilitate efficient polariton condensation and subsequent coherent light emission.

    Low Threshold Condensation: Achieving condensation at low excitation densities (e.g., via National Institutes of Health (NIH) | (.gov) suggests the use of bound states in the continuum https://pmc.ncbi.nlm.nih.gov/articles/PMC11026397/ } or BIC states) can result in more energy-efficient light generation.

    Enhanced Exciton Transport: The coherent nature of polariton condensation can facilitate efficient energy transfer and exciton transport in the active material of a photovoltaic device. This can lead to increased charge separation and collection, reducing energy losses and improving overall efficiency.

    Controlling the Condensate: Manipulating the potential landscape and gain profile, as demonstrated by optically controlling localization in fixed photonic chips, allows for the selective excitation of desired polariton condensate modes, potentially leading to optimized light for specific photoconverting chips.

    Low Losses and Decoherence: Minimizing losses in the microcavity and mitigating decoherence effects from interactions between the condensate and the exciton reservoir are crucial for achieving and maintaining the coherent light from the condensate and for enhancing overall efficiency.

    Utilizing Coherent Properties: The coherent nature of the light emitted by exciton-polariton condensates, particularly if it can be specifically tailored to match the absorption spectrum of the photoconverting chip, could improve the efficiency of energy transfer and conversion to electrical power.

    Wavelength Tuning and Sub-Bandgap Absorption: The energy levels of polaritons can be tuned by engineering the properties of the microcavity and the excitonic material. This tunability allows for better matching of the light spectrum with the absorption properties of the photovoltaic material, potentially enabling the absorption of light at energies below the material’s bandgap, which is typically lost in conventional solar cells.

    Reduced Energy Losses: By maintaining strong coupling between excitons and photons, polariton condensates can effectively reduce energy losses associated with non-radiative decay processes and scattering, resulting in a more efficient conversion of light energy into electrical energy.

    Manipulation of Polariton Condensates: The ability to manipulate the propagation and flow of polariton condensates, as demonstrated in experiments, opens up new avenues for controlling the interaction of light with the active material in a photo conversion device. This control can potentially lead to optimized light absorption and charge separation pathways, further boosting efficiency.

    Exploiting Quantum Coherence: Recent research suggests that enhancing quantum coherence in long-lifetime exciton-polariton condensates could lead to higher efficiencies, potentially by spatially separating the condensate from the reservoir of carriers.

    In essence, optimizing the material platform and cavity design to promote low-threshold, room-temperature condensation with high coherence and minimal losses, combined with careful control and tailored light output to match the properties of the photoconverting chip, are key circumstances for achieving very high efficiency photo conversion using exciton-polariton condensates.

    Dear Dr Andrea Rossi,
    Is it necessary the use of a vacuum pump to make an Ecat ?
    Matthew

  • Andrea Rossi

    Svein:
    Thank you for your support,
    Warm regards,
    A.R.

  • Svein

    Dear Andrea
    I agree with your decisions.
    However, there are several underlying bodies where R & D is a task.
    I can, carefully, inform these so that desired decisions are not avoided.
    I can prepare this without major conflicts.

    However, I look forward to the largest quantum leap in energy since Cyanobacteria managed to create and store energy through photosynthesis over 3.5 billion years ago.

  • Ambrogio

    Dr Rossi,
    Again about the paper
    http://www.researchgate.net/publication/330601653_E-Cat_SK_and_long_range_particle_interactions
    is it fundamental the vacuum as explained in paragraph 4 ?
    Ambrogio

  • Andrea Rossi

    Svein:
    As soon as we will start the deliveries we will contact them, maybe with your help. To do it before is a loss of time. They are not R&D, they need working solutions.
    Thank you anyway for your help,
    Warm Regards,

    Dear Andrea
    The following agreements have been published now on July 10:

    Norway pledges NOK 2.8 billion for energy security in Ukraine
    The government is entering into three new agreements to support the upgrading of the energy system and green transition in Ukraine.

    – After more than three years of full-scale war and repeated Russian attacks, Ukraine’s energy infrastructure is being hit hard and in a targeted manner, says Foreign Minister Espen Barth Eide in a press release.

    He says the agreements for the reconstruction and transition of the energy system provide increased energy security and more green energy in Ukraine. The agreements will be signed with Minister of Trade and Industry Cecilie Myrseth and Ukraine’s Minister of Energy Herman Halushenko in Rome on July 10.

    Myrseth says the agreement contributes to ensuring the population’s access to electricity and heat in winter.

    The three agreements have a total framework of NOK 2.8 billion over three years. In 2025, NOK 1.65 billion will be paid out for measures to repair critical infrastructure, strengthen energy security and promote renewable energy.

    It is obvious that E-Cat is the best solution here.
    How can I now be of service to Leonardo C. so that we can quickly start the necessary activities in this regard?

    Dear Andrea Rossi,

    There are many reasons why a prototype design never reaches the marketplace.

    1. The manufacturing organization lacks the skill set to change the prototype design into a production unit.
    2. The mass production yield is so low that it adversely affects profitability.
    3. An external competitor releases an equivalent unit at lower cost or otherwise captures the market.
    4. The manufacturing organization loses interest in the prototype technology.
    5. The manufacturing organization is bought by an organization threatened by this new technology and “shelfs” the effort.
    6. Probably many more which I have not considered.

    A. Do you have legal protection in the event the manufacturing organization fails to produce?

    B. If that should happen, do you retain your control on the design and marketability?

    Dear Andrea
    The presented message: https://x.com/LeonardoCorpor3/status/194201129800010992 from Leonardo Corporation about the transfer of expertise to the new Global Licensee was very important and encouraging.
    The assumption of deliveries of the E-Cat by 2025 as well.

    As the chief scientist of the new Global Licensee, I hope that it is still possible for your followers to direct technical questions to you in this blog until further notice.
    Regards Svein

  • Steven Nicholes Karels

    Dear Andrea Rossi,

    The July 7 status report was disappointing. Perhaps you could enlighten us with how many prototypes were tested, what types (Wattage) of prototypes were tested, and what types of testing were performed. Were these prototypes existing units or ones built by your partner(s)?

  • Calle H

  • Juan Carlos

    Hello Everyone,

    I had understood that some kind of major status report
    was going to be made yesterday, July 7th.

    I had assumed, (perhaps naively?) that such a report would
    be made here in this blog.
    But now I don’t find it, and no one else seems to be complaining.
    So I am wondering?
    Was it made somewhere else and I just missed the announcement of “where”?

    And if that is indeed the case,
    could someone please publish the link thereto here?

    I have really been “itching” to get a new update.

    Thanks in advance,
    JC

    Gianluca:
    As I said, the reason of the noise is confidential.
    1 kW module at a distance of 1 m produces about 30 dB(A): for the non experts, it is the noise of a standard refrigerator everybody has in an apartment,
    Warm Regards,
    A.R.

  • Gianluca

    Dearest A.R.
    if they were vibrations (of the plates) depending on the frequency they could be easily attenuated with appropriate measures (insulating materials). Is it possible to know what noise the 1Kw module produces at a distance of one meter?
    Thanks a lot

  • Italo R.

    Dr. Rossi,
    I understand that at the moment we cannot know where the Ecats will be produced.
    However, this will affect the cost of purchase.
    I ordered from Italy years ago, and if the production took place for example in the USA, I would also have to pay the duty that will be applied at the time of delivery.
    If the production was in Europe, I would not have to pay this duty.

    Kind Regards,
    Italo R.

  • Stephen

    Hi Andrea Rossi

    Thanks for your answers to my questions.

    With question 6 I was asking if you could indicate where the noise came from maybe which component for example . But I was concerned not to ask too much if the sound source is protected knowledge for example.

    Thanks again and best regards

    Stephen

  • Andrea Rossi

    Stephen:
    1. humm
    2. to any assembly with logarythmic sum of the noise of each module of the assembly
    3. if necessary
    4. yes, logarythmically
    5. no
    6. I don’t understand what you mean: can you rephrase ?
    Warm Regards,
    A.R.

  • Stephen

    Dear Andrea Rossi

    May I ask some clarification question about the low noise 50dbA output?

    First of all I note it’s clear it’s within normal limits for electronic devices and can easily be managed but I’m curious about it for applications and scalability reasons for example if it is used with a sound system or many devices are used together.

    In these cases I think it’s easy to manage the sound in a suitable enclosure fir example.

    1 . Can you describe the nature of the noise. Is it:
    a) a white or grey noise like.
    b) a whistle
    c) a hummm
    d) a resonant chord more choir.
    d) clicks or pops
    .e) or could you describe its nature if some thing else

    2. Is it applicable only to the larger devices or all devices and how does it scale with size.
    3. Could it be added to the data sheet?
    4. Will it scale with multiple devices,?
    5.Is it due to fan noise ?
    6. Or without giving away too much some other components in the device?

    Looking forward to the announcement tomorrow. Good luck with it !

    Thanks and best regards
    Stephen
