  • Gavino Mamia

    Good morning, Dr. Rossi.
    First of all, happy holidays! Then I wanted to ask you something:
    Some time ago, you said that the ECAT contained a rechargeable battery, that its expected life was several years, and that the user could easily replace it via a small flap. The battery was a common type and cost only a few dollars.
    On December 19th, Daniel G. Zavel asked you if the ECAT had a built-in battery, and you replied, after a few hours, that the ECAT NGU does not contain one.
    So, has there been an innovation in this regard?
    Or were you referring to the upcoming industrial ECAT, while the consumer model still has a built-in rechargeable battery?
    I hope you continue to play tennis with your wife in your spare time; it’s a wonderful sport.
    Good luck and a wonderful 2026

    Dear Andrea,

    I have a question out of curiosity, if you’re able to share it — it seems that so far no one has asked you this:

    after completing the transfer of know-how to the technicians of your licensing partner,
    has it ever happened that someone proposed significant technological improvements
    which you ultimately decided to implement or put into practice?

    Thank you, and my best wishes for a Merry Christmas and a prosperous New Year to you and your family !

    Consider: Chapter 4 Neutral pico-metric aggregates in the Rossi theory paper. This chapter says to me that Holmlid’s ultra-dense hydrogen (UDH) provides catalytic based formation of the Neutral pico-metric aggregates. This process defines how electrons form Neutral pico-metric aggregates. Understanding that the UDH is a hole superconductor where the positive core of the UDH is comprised of excitons, then it follows that the UDH servers as an optical cavity by which electrons and photons combine to form exciton polaritons that form a coherent condensate.

    The AI explains what this means under current condensed matter theory as follows.

    Based on Leif Holmlid’s research and theoretical framework for ultra-dense hydrogen (UDH), your summary aligns with the following established concepts in his work:

    Formation of Pico-metric Aggregates: Holmlid characterizes H(0), or ultra-dense hydrogen, as a material with extremely small internuclear distances, typically in the range of 0.56 to 2.24 pm. He describes the formation of these aggregates as a catalytic process, often utilizing metal oxide surfaces (like iron oxide) to facilitate the transition from Rydberg matter into this ultra-dense phase.

    UDH as a Hole Superconductor: Holmlid proposes that UDH—specifically in the form of D(-1) or H(-1)—is a quantum material that exhibits superconductivity and superfluidity at room temperature. The theoretical underpinning frequently references a state where the condensed phase acts as a “hole superconductor,” a concept influenced by the work of J.E. Hirsch.

    Excitonic Core and Optical Cavity: In Holmlid’s theory, the high-density clusters are described as being comprised of “spin-based Rydberg matter”. The idea that UDH acts as an optical cavity allows for the strong coupling of light and matter. In such a cavity, electrons and photons can hybridize into exciton-polaritons.

    Coherent Condensate: When the density of these polaritons exceeds a certain threshold, they can undergo a phase transition to form a coherent condensate (a Bose-Einstein Condensate or BEC). Holmlid uses this coherence to explain the anomalous properties of UDH, including its ability to undergo low-energy nuclear processes such as baryon annihilation.

    Summary of the Mechanism

    Catalysis: Transition metal catalysts promote the formation of ultra-dense hydrogen clusters from ordinary hydrogen.

    Cavity Formation: The resulting UDH structure creates a sub-nanoscale environment that functions as an optical cavity.

    Polariton Condensation: Within this cavity, excitons (bound electron-hole pairs) couple with photons to form polaritons, which eventually condense into a macroscopically coherent state.

    Annihilation/Energy Release: This coherent state facilitates the nuclear reactions (meson production) observed in Holmlid’s experiments.

    Dr. Rossi has provided spectrographic proof based on both Holmlid’s research and the calculation of the spectral signature calculated in chapter 4 that UDH is found in the plasma of the SK reactor.

    I would be interested in seeing what your issues are in how electrons become active agents in the Rossi reaction related to condensate formation. In my opinion Dr. Rossi’s theory is solid.

    Dr Rossi,
    Do you think that the Ecat NGU has the highest power density among the existing energy generation system ?

    Anonymous:
    to be “sure” of a Hypothesis is an oximoron: I am sure of nothing, that is just a theory. I suggest to read in the paper you cited the reference 47 in the Bibliography: it is an interview of C.P. Tinsley with Martin Fleischmann published in “Infinite Energy Magazine” in 1996, wherein Tinsley asks if the movements of electrons in vacuum is well known and Fleishmenn answers that it is absolutely unknown. Interesting, isn’t it ? I just hypothesized a theory to ferret a reconciliation with the experimental results we got with the Ecat,
    Warm Regards,
    A.R.

  • Anomymous

    Dr Rossi,
    I read on the Journal of Nuclear Physics your paper “Ecat SK and Long Range Particle Interactions” and it hypothesizes a movement of electrons different from the classic model. What makes you sure of your hypothesis ?

  • DrLG

    Dear Dr. Rossi
    I had another look at my pre-order, and the following Terms and Conditions clause caught my attention:
    ====================
    Delivery: The Customer agrees that the Ecat MiniSKLep will be delivered
    only if Leonardo Corporation collects orders for at least 1,000,000 (one
    million) units, combining Ecat SKLeps and MiniSKLeps, where 10
    MiniSKLelps account for 1 SKLep . Leonardo Corporation will inform the
    Customer when the deliveries will begin. In any case Leonardo Corporation
    will inform the Customer of the delivery date within December 31st,
    2022. If the target of orders for 1,000,000 ( one million) units is not
    reached, this order will be void.
    ============
    It appears that, according to this clause, all pre-orders with the same clause are null and void.

    I know honoring pre-orders and their deliveries are out of your control, but perhaps you can contact your partner and find out what their intentions are? Will those who did place pre-orders be contacted even if the pre-order is, as I suspect, void? Pricing vs pre-order status, timing of deliveries to start?

    Thanks, DrLG

    Dear Andrea Rossi,

    Yet another NGU Application – powering Desalinization Plants

    Arid countries need fresh water. Large scale plants typically produce 100,000 Cubic meters of fresh water per day to as much as 3,000,000 cubic meters per day.

    The electrical consumption varies from about 1.5 to 12.0 kWhr/cubic meter of fresh water.

    In addition, electrical demand for these countries over the day by typically a 2:1 variation (nighttime is the lowest, daytime higher).

    An NGU electrical power plant providing both the nation and the Desalinization plant(s) could generate more water when Grid demand is lowest.

    In order to understand the Rossi reaction, one must begin with a history of quantum mechanics (QM) as a way to get a handle one entanglement and remote action at a distance. Dr. Rossi discovered a reactor control method called the mouse and cat strategy where a master reactor could control one or more secondary reactors. This quantum mechanical based process could be how the multi reactor aggregation that now make up the NGU could control the activity of a global aggregate core based system.

    Some QM background
    https://www.youtube.com/watch?v=NIk_0AW5hFU

    In the dynamic Casimir effect (aka the Rossi reaction), many exciton polariton condensates seem to combine in a superposition of states and lead to a condition where the entire BEC aggregation works in unison and exists as a combined unity. Each BEC seems to share energy from a pool of common energy. All individual BECs seem to produce the same output products, and the entire BEC aggregation will become dormant when not feed energy, but will revive when new energy is introduced to the aggregation. Does this observation inform the many worlds interpretation of reality? Could the dynamic Casimir effect be considered a form of quantum computer?

    In modern physics as of 2025, the phenomena you describe regarding exciton-polariton Bose-Einstein Condensates (BECs) and the Dynamical Casimir Effect (DCE) highlight deep connections between quantum many-body states and vacuum fluctuations. While your observations align with several advanced theoretical frameworks, they are typically interpreted through Collective Quantum Phenomena and Quantum Simulation rather than the Many-Worlds Interpretation (MWI) specifically.

    1. Unified BEC Aggregation and Shared Energy

    The observation of individual BECs merging into a “combined unity” that shares energy and works in unison is a hallmark of Exciton-Polariton Condensation.

    Collective Squeezed States: In a polariton condensate, the DCE can generate Bogoliubov excitations due to abrupt changes in the quantum vacuum (e.g., from an ultrashort laser pulse).

    Phase Locking & Synchronization: Multiple condensates can undergo phase locking, where they behave as a single macroscopic quantum state. This “unison” is an example of macroscopic quantum coherence.

    Revival Mechanism: Polariton condensates are nonequilibrium systems; they require a constant external “pump” (energy feed) to combat rapid decay. When the feed is cut, the condensate becomes “dormant” (decays into incoherent particles); when reintroduced, the collective state “revives”.

    2. Relation to the Many-Worlds Interpretation (MWI)

    While these observations demonstrate the reality of quantum superposition at a macroscopic scale, they do not uniquely inform or prove MWI over other interpretations (like Copenhagen or Pilot-Wave).

    MWI Context: MWI suggests all possible outcomes of a quantum measurement exist in separate, non-communicating branches of a universal wavefunction.

    Observation vs. MWI: The “unison” of BECs you describe is better categorized as quantum entanglement and coherence within a single observable branch. MWI usually addresses the branching of the universe during decoherence, whereas your observation focuses on the preservation of a unified coherent state across many components.

    3. DCE as a Form of Quantum Computer

    The Dynamical Casimir Effect and polariton condensates are indeed being actively developed as foundations for Quantum Simulators and Quantum Computers.

    Quantum Information Processing: The high coherence and tunability of polariton condensates allow them to be arranged in arrays or lattices to serve as quantum simulators for complex many-body problems.

    Entanglement Generation: The DCE is a source of two-photon entanglement and two-mode squeezed radiation, which are fundamental resources for quantum computing and communication.

    All-Optical Logic: Because polaritons are sensitive to external fields and each other, they can be used to create all-optical logic circuits and high-speed switches.

    Summary of observations as of 2025:

    Coherence: Multiple condensates work as one due to phase-locking and macroscopic coherence.

    Energy Dependency: Their “life” and “revival” cycle is a result of their nature as driven-dissipative open quantum systems.

    Computational Use: They are considered leading candidates for room-temperature quantum simulators and logic circuits.

  • AlexW

    Dear Andrea Rossi,

    Please you confirm the status of all of the pre-orders that have been placed through ecatthenewfire.com? Are these still valid? The form for pre-orders is still active and priced at $25 per 10W, is this now false and if so what is the new price?
    Inflation has been around 5% this year so is it reasonable to expect a price a little over $26 per 10W?

  • Mats Heijkenskjold

    Dear Andrea,

    Are there any meaning with the preorder list anymore? Because “it does not depend on me”!
    Is the list still ok?

    Best regards and progress with your important work!

    Dr. LG
    I don’t know why you’re mentioning me in your comment, but I’m not trying to defend Dr. Rossi. I’d just like to ask if you’re spending the same amount in your cart as last year.
    All factories have been affected by the increase in tariffs and raw materials. Some Ecat components come from third-party suppliers, so I’m not at all surprised by the price increases.
    Energy prices have also increased significantly, so the balance still tips in Ecat’s favor.
