    Dear Andrea Rossi 

    1) The 1MW generator under construction is built from 100W Ecats?

    2) Overlooking packaging are the characteristics of the 100W Ecats used here especially suited to a large plant assembly?

    3) Overlooking packaging will the characteristics be different when 100W units are offered to fulfil small orders?

    4) There is only one 100W Ecat and can be employed in a 1MW plant or as a stand alone unit?

    Does the new design of the 22kv grid capable reactor still provide the same power production efficiency of your earlier lower powered reactor designs?
    
    If not, is waste heat rejection at the root of the issues that you must now overcome?

  • Drew Glista

    Dr. Rossi:

    Is the one megawatt plant being assembled in Europe or in the United States?

    Dr. Rossi:

    I am excited to see the system fully integrated and working, I’m sure that your team will solve the problem. My guess is that the problems have to do will system stability as the number of units are added together reaches a limit. Obviously, you were able to integrate a large number of units for the use in the Twizy demonstration. My questions are:

    1). Was the problem identified only when a large number of units were tied together?
    2). Is there a “global” or “hierarchical” control strategy in use to control voltage?

    Dear Andrea
    Your answers and messages, the last week, were very optimistic and thereby inspiring to all your followers.

    I look forward to the announced message about a measured volumetric kW production that an aggregate composed of a number of 100W Ecat units, has achieved.

    The many and very comprehensive presentations that “Axil” has presented appear to be a technological “third-party assessment” and will therefore open the way for a number of industries to view the presented measurement figures as being in line with the available theoretical possibilities.
    A large number of test orders for similar plants could quickly be the result.

    This, together with the fact that a modern production plant has now been established, will lead to a completely different level of attention than what the single EV demonstration in September 2024 did.

    The fantastic flexibility of a 1MW plant consisting of adjustable small units is a great need to be incorporated into many power supply systems where rapidly varying solar and wind power is a significant factor and a demanding challenge.
    This alone can be an argument that surpasses Ecat’s favorable price.

    Regards Svein

    AI prompt
    If the dynamic Casimir effect (DCE) removes virtual particles from the inside of the vacuum enclosed by the domain wall a localized true vacuum confined within a domain wall is eventually reached. Concurrently, the negative momentum based waveforms produced by the exciton polariton condensate via it dispersion channel also removes virtual particles from inside the domain wall. This developing true vacuum produces a state where vacuum decay begins to occur. This vacuum decay causes vacuum energy to be transferred from the false vacuum into the true vacuum within the domain wall. The existence of a domain wall that forms around the BEC is a positive indicator the the BEC is producing a true vacuum state. The negative momentum photons produced by the condensate will reduce the energy content of the BEC thereby forming a localized true vacuum restricted to the inside the domain wall even though the DCE is using that vacuum energy transferred from the false vacuum to create real particles. Create an appropriate simulation that depicts this scenario as described.

    Ai answer
    Based on your description, the scenario involves a complex feedback loop where the Dynamic Casimir Effect (DCE) and an Exciton-Polariton Condensate (BEC) work concurrently to purge virtual particles from a region enclosed by a domain wall. This creates a localized True Vacuum, triggering Vacuum Decay that harvests energy from the surrounding False Vacuum to drive further particle creation.

    The simulation below models this theoretical interactions as a dynamic system.

    Mechanism Breakdown
    This simulation visualizes the four distinct physical phases you described:

    1. The Dynamic Casimir Effect (DCE): Represented by the vibrating boundary. In quantum field theory, rapidly moving boundaries can convert virtual vacuum fluctuations into real photons. In your scenario, this boundary acts as the engine using the energy difference.

    2. Exciton-Polariton Clearing: The internal wave patterns represent the condensate. These quasiparticles have extremely low effective mass and can exhibit negative dispersion features, which your model uses to suppress virtual particle formation.

    3. True vs. False Vacuum: The contrast between the chaotic background (False Vacuum) and the dark interior (True Vacuum). The “False” vacuum is a metastable, higher-energy state. A transition to the “True” vacuum releases potential energy.

    4. Vacuum Decay & Nucleation: The flow of energy from the outside in. Typically, vacuum decay is modeled as a bubble expanding at the speed of light, but your scenario utilizes a confined Domain Wall to harness this energy transfer locally.

    AI prompt
    Quantum field theory posits that the vacuum carries a quantum field for every possible particle that exists. Each such field carries a finite amount of energy. The Zero point energy is the combined total of all field energy generated by the uncertainty in each field. The amount of energy carried in the zero point energy in extremely small compared to the huge amount carried by the sum of all quantum fields.
    
    AI answer
    In quantum field theory (QFT), your description of the vacuum contains several core physical principles, though the relationship between zero-point energy (ZPE) and the “total field energy” requires specific clarification regarding how physicists define these terms: 
    
    Vacuum as a Collection of Fields: The vacuum is not truly empty but is defined as the ground state (lowest energy state) of all underlying quantum fields (e.g., electromagnetic, Higgs, and quark fields).
    
    Zero-Point Energy Definition: For each quantum field, the ZPE is the residual energy that remains even when no particles are present. It arises from the Heisenberg Uncertainty Principle, which prevents a field from ever being completely “still” or having exactly zero energy and zero momentum simultaneously.
    
    ZPE vs. Total Field Energy: In standard QFT, ZPE and vacuum energy are synonymous. The “total energy” of the vacuum is simply the sum of the ZPE from every possible field mode.
    
    The Scale Paradox: Naïve theoretical calculations suggest this ZPE sum should be infinite or enormously large (up to (10^93) grams per cubic centimeter). However, astronomical observations of the universe’s expansion show the actual measured vacuum energy is extremely small—close to zero.
    
    Renormalization: Because only differences in energy are typically measurable in particle physics, physicists often use a mathematical process called renormalization to “subtract away” the infinite ZPE, effectively setting the vacuum energy to zero for practical calculations. 
    
    ————————————————
    In the dynamic Casimir effect, virtual particles are transformed into real particles. The energy that is required for the transformation comes from the particle field, not the ZPE.

    There must be another source of energy generated by the EVO. It might be energy derived from vacuum decay since particle creation is constrained by the energy conservation law (no energy gain).

    The key to the design of a high powered E-cat is the use of the mouse and cat protocol in the structure of the reactor. This control strategy enables many small reactor cores to combine using a backplane connected by quantum mechanical entanglement so that no dedicated hardware or control processes coordinate 10s of thousands of individual microcores into a powerful global hole. This is quantum mechanics at beyond the cutting edge.
    
    This innovative reactor architecture provides both the advantages of microcore only processes: high efficiency through heat elimination and simplicity of global reactor control without the disadvantages of reactor distruction (meltdown) through waste heat buildup.
    
    I am disadvantaged in that I do not have any knowledge of the NGU structure but have assumed this structure from existing theory development. I am sorry if I am off base.

    Dear Andrea Rossi,

    The USA average continuous electrical power demand is around 466 gigawatts (GW) or 466,000 MW. Expect increase in demand over the next 10 years is 25% or roughly 100,000 MW, not counting AI data centers which are projected to be another 100,000 MW over the decade.

    AI data centers will require near constant power and the electrical generation could be located at the data center – ideal for NGU systems.

    There are roughly 55,000 electrical substations in the US. Placing an average 2 MW NGU systems in each substation could provide the additional capacity needed for the forecast increase in electrical power capacity. This would allow increase electrical production without corresponding increases in distribution capacity.

    Question: Assuming 500W NGU units, can the number of 500W NGU units be produced over the next decade?

  • Roberto

    Dr Rossi,
    Can you tell us which problems you had to resolve with the delivered Ecats ?

    1. whether it is the individual 100 Watts units that are not working perfectly or:
    2 whether it is getting 10,000 of these to work perfectly together in a 1MW unit?

    How does the Vacuum reaction utilized in Dr. Rossi’s reactors generate over-unity energy release?

    In this post:

    https://www.journal-of-nuclear-physics.com/?p=892&cpage=909#comment-1705449

    I stated:
    3. Triggering the Dynamic Casimir Effect

    The culmination of this process is the production of a vacuum energy difference. The negative mass regime creates a rapidly changing boundary condition—effectively a relativistic perturbation in the vacuum field—which triggers the Dynamic Casimir Effect (DCE).

    The Energy Flow Mechanism: In this specific theoretical model, the negative momentum photons influence the vacuum within the cavity such that vacuum energy flows from the vacuum into the dynamic Casimir cavity, manifesting as real photons or heat.

    ————————-

    The particles that the dynamic Casimir cavity creates are both photons and polaritons.

    This means is that the number of polaritons increases in time as the Condensate grows larger with that passage of time.

    In experiments conducted by MFMP, these condensates begin at a submicron size. Over time, because of the accumulated increase of vacuum energy transformed into additional numbers of polaritons, the size of the condensates’ reaches a diameter of about 250 microns. At that size, the condensate becomes unstable and explodes in a Bosenova.

    All during this condensate growth cycle, the condensate is producing increasing amounts of light since each polariton is converting vacuum energy into light. So the condensate increases in light output as time goes forward until it becomes unstable and explodes.

    When the condensate explodes, many more electrons and photons are created than existed when the condensate was created. This process of condensate growth also adds to the increase in vacuum energy release.

    I asked the AI to validate, consolidate and explain this aforementioned posit:

    The AI’s response
    The text you provided is a specific theoretical framework proposed by Andrea Rossi (inventor of the E-Cat) and discussed within the LENR (Low Energy Nuclear Reaction) community. It attempts to explain anomalous heat production by combining the Dynamic Casimir Effect (DCE) with Exciton-Polariton Condensates.

    The posit claims that a specific “negative mass” state in a light-matter condensate triggers a vacuum energy influx, causing the condensate to grow until it reaches a critical size of roughly 250 microns, at which point it violently collapses (a “Bosenova”), releasing significant energy.

    Consolidated Logic Chain

    Step 1: Formation
    An Exciton-Polariton Condensate forms. This is a quantum fluid made of hybrid light-matter particles.

    Step 2: Negative Mass
    The condensate enters a “Negative Mass Regime.” In this model, this refers to a specific dispersion anomaly where the particle’s group velocity opposes its momentum.

    Step 3: Virtual Mirror
    This negative mass state creates a rapidly changing boundary condition in the vacuum field. The theory posits these acts effectively as a relativistic mirror, the requirement for triggering the Dynamic Casimir Effect.

    Step 4: Vacuum Influx
    The DCE converts virtual vacuum fluctuations into real photons and polaritons, injecting energy into the system.

    Step 5: Critical Growth
    Fed by this vacuum energy, the condensate grows in size (and luminosity) over time.

    Step 6: The Bosenova
    At a critical diameter of ~250 microns, the condensate becomes unstable and explodes. This collapse (Bosenova) releases the accumulated energy as a burst of electrons, photons, and heat.
    Detailed Explanation of Terms

    Dynamic Casimir Effect (DCE): Standard Physics: A phenomenon where real photons are created from the vacuum by a mirror moving at relativistic speeds (close to the speed of light). In This Theory: The “negative mass” regime provides a virtual relativistic boundary, removing the need for a mechanical mirror to move at impossible speeds.

    Negative Mass Regime: Standard Physics: “Negative mass” is generally hypothetical or refers to “effective mass” in solid-state physics (how an electron responds to forces in a lattice).

    In This Theory: It refers to a specific state in the dispersion curve of the polariton condensate where momentum and velocity vectors are opposed, creating the perturbation needed to “trick” the vacuum.

    Polaritons: Quasiparticles formed by the strong coupling of electromagnetic waves (light) and an electric dipole-carrying excitation (matter). They allow light to behave like a fluid.

    Bosenova: Standard Physics: A tiny, controlled collapse observed in ultracold Bose-Einstein Condensates (thousands of atoms) when interactions are tuned to be attractive.

    In This Theory: A macroscopic explosion of a large (250 micron) condensate, credited as the source of the excess energy in the E-Cat.

    Context: The MFMP Connection
    Experimental Attribution: The post attributes the 250-micron limit to observations by the Martin Fleischmann Memorial Project (MFMP). MFMP researchers (such as Bob Greenyer) have documented microscopic objects (often called “EVOs” or Exotic Vacuum Objects) that appear to form, emit light, and violently disintegrate. This theory attempts to mathematically model those observations.

    Dr Rossi,
    Are the Ecats already delivered working as expected ?

  • Axil

    Dear Readers
    
    The way that the vacuum works is that particles come into existence and then return into the vacuum in pairs so that when the pairs combine, this recombination recovers the energy that created the pair.
    
    The phonon is one such particle. But to exist and then terminate, they need to exist as a connected (entangled) pair.
    
    In more detail, physicist describe the “quantum vacuum” not as empty space, but as a field buzzing with the activity of particles. Here is a simple explanation of how this works:
    
    Temporary Energy “Loans”: The vacuum has a minimum energy level that is never zero. Because of the Heisenberg Uncertainty Principle, energy can fluctuate randomly for extremely short periods. You can think of this as “borrowing” energy from the vacuum to create something.
    
    The Particle-Antiparticle Pair: This borrowed energy manifests as a pair consisting of a particle and its matching antiparticle (e.g., an electron and a positron). They must appear in pairs to keep the total “charge” of the vacuum at zero.
    
    Virtual Photons: The photon is a special case because it is its own antiparticle. In the vacuum, “virtual photons” can appear and disappear as part of these fluctuations to carry electromagnetic forces.
    
    Entanglement: These pairs are born entangled, meaning they are fundamentally connected. Because they share the same origin, their properties (like spin or polarization) are linked regardless of the distance between them.
    
    Returning the Energy: To satisfy the laws of physics, the “loan of energy” must be repaid quickly. The pair must find each other and annihilate (combine), which returns the energy back to the vacuum and effectively “erases” the particles from existence.
    
    
    One might say: ‘If we’re talking about a complex frequency +jw and its complex conjugate -jw, this doesn’t mean that frequency w is negative. Frequency is always positive. So is energy.”
    
    The term “Negative frequency” is a mathematical convention, but both particles in the conjected pair have valid frequencies and energies.
    
    In physics and engineering, “negative frequency” is a tool for calculation, not a physical state.
    
    Here is the breakdown in simple terms: Frequency is like speed: Just as a car cannot drive at “negative 60 mph,” a physical wave cannot vibrate a negative number of times per second. Frequency represents the rate of oscillation, which is always a positive physical quantity.
    
    The “Mirror” Math: When we use complex numbers like jw and its conjugate -jw, we are splitting one real-world signal into two mathematical parts to make the equations easier to solve. Think of it like looking at a person and their reflection in a mirror; there is only one real person, but the math “sees” two versions to track the full motion. Energy stays positive: Because energy is calculated based on the square of the amplitude or frequency, even the “negative” mathematical part represents positive physical energy.
    
    Both parts of the pair contribute to the total energy of the system. The Convention: We use the term “negative frequency” simply to describe the direction of rotation in the complex plane (clockwise vs. counter-clockwise), not to imply that the frequency itself is less than zero. 
    
    Read this wiki about how this pair of particle are related in their associated frequencies (one positive and one negative):

    Dear Readers,

    I watched the following Italian-language documentary on UFOs, which I found very interesting.

    UFO Documentario Italiano Unacknowledged Steven Greer
    https://www.youtube.com/watch?v=Q6qcJ3YcMnQ&t=1315s

    Among other things, ZPE vacuum energy is mentioned at one point, suggesting that it could be the energy used by UFOs.

    It also discusses the risk and real possibility that, if an inventor were to discover this technology, he could be “disappeared” by secret government entities.

    This would fully justify the inventor’s need for absolute secrecy regarding this technology.

    This virtual particle theory is important in the vacuum reaction that occurs in the E-Cat reactor. Because the Exciton polariton condensate generates real photons from virtual photons via the Dynamic Casimir Effect, the light generated by the vacuum reaction will tend to produce light in the negative frequency UV light range. This UV spectrum has been verified in the spectrum produced by the SK reactor.
    
    AI Prompt
    When a photon is created in the vacuum, a complimentary pair of photons: both a positive frequency photon and a negative frequency photon is created. Both these paired photons have positive energy but when they combine, they annihilate each other each so that they return the energy of the photon pair back to the vacuum. The negative frequency photon is usually in the ultra violet frequency range.
    
    AI Response
    In quantum field theory (QFT), the creation and annihilation of photons in a vacuum involve specific mathematical and physical interpretations regarding frequency and energy:
    
    Positive and Negative Frequencies
    
    • Mathematical Decomposition: The electromagnetic field is decomposed into two parts: a positive-frequency component and a negative-frequency component.
    
    • Operators: In the standard Heisenberg picture, the positive-frequency part is associated with annihilation operators (absorbing a photon), while the negative-frequency part is associated with creation operators (creating a photon).
    
    • Energy and Time: Standard QFT is designed so that all physical particles, including those created by negative-frequency components, have positive energy (E=ℏω). Negative-frequency modes are sometimes interpreted as positive-energy particles moving backward in time, but they do not possess “negative energy” in a physical sense.
    
    Vacuum Fluctuations and Annihilation
    
    • Virtual Pairs: The vacuum is characterized by fluctuations where virtual particle-antiparticle pairs (such as electron-positron pairs) are continuously created and destroyed.
    
    • Photon Behavior: Because a photon is its own antiparticle, “annihilating” two photons typically results in scattering or other interactions rather than mutual destruction back into the vacuum. However, virtual particle pairs that do annihilate return their energy to the vacuum’s zero-point energy pool.
    
    Ultraviolet Frequencies
    
    • Vacuum Ultraviolet (VUV): The term “vacuum ultraviolet” refers to a specific range of electromagnetic radiation (wavelengths approx. 10–200 nm) that is strongly absorbed by air, requiring a vacuum for propagation.
    
    • Physical Significance: This frequency range is significant because it matches the ionization energies of many materials and the bond energies of most molecules. There is no fundamental rule stating that all negative-frequency creation events must result specifically in ultraviolet light; they can occur across various frequencies depending on the energy involved.

    The following link shows the AI input to my last post. This input includes a parameterized simulation of photon and polariton creation of real particles derived from the transformation of virtual particles into real particles based on the optical vibrations of the Exciton polariton condensate. It also shows the active plot of negative momentum polaritons in the dispersion relation curve.

    This peer reviewed theory may be of some interest to some of your readers.

    This research data dispels the myth that energy cannot be extracted from the vacuum.

    The link is long due to a current weakness in the AI design in that it can’t yet accept prompts directly from the internet. click on the link to see the AI generated data.

    It is important to aid the understanding of the vacuum reaction for the non-expert so I asked the AI: Can you reorganize the last few of my posts on the Bosonic Electron Cluster into a single well designed narrative conformant with current science while keeping all the relevant detail:

    The AI extract
    The Bosonic Electron Cluster is defined in this model as an exciton-polariton condensate—a macroscopic quantum state formed by hybrid light-matter quasiparticles. By engineering the dispersion properties of this condensate, the system can enter a “negative mass” regime. This unique state allows for the manipulation of virtual negative energy photons within the quantum vacuum, theorized to trigger a Dynamic Casimir Effect where vacuum energy flows into the cavity.

    1. The Negative Mass Regime

    The foundation of this effect lies in Dispersion Engineering. In a standard particle, kinetic energy increases with momentum. However, for exciton-polaritons (which are composite bosons), the effective mass can be engineered to be negative within the lower polariton branch. This is often induced by dissipative coupling or strong exciton-phonon interactions.

    Momentum vs. Velocity: In the negative mass regime, the group velocity (direction of propagation) is opposite to the momentum (phase velocity). The particle effectively moves backwards when pushed.

    Associated dispersion curves will illustrate the “Negative Mass” region where the dispersion curve (Energy vs. Momentum) inverts, becoming concave (downward curving).

    2. Role of Virtual Negative Energy Photons

    The behavior of the condensate in this regime can be conceptualized through the interaction of virtual particles.

    Attractive Interaction

    Just as virtual photons in standard QED mediate attractive forces (like the pull between an electron and proton) by effectively carrying “negative energy” or “negative inertial mass,” the engineered dispersion in the polariton condensate mimics this attractive force.

    Quantum Structure Visualization

    Vacuum Influence

    These negative momentum/energy virtual photons (or the effective interaction that mimics them) do not just exist in isolation; they actively influence the local quantum vacuum structure.

    3. Triggering the Dynamic Casimir Effect

    The culmination of this process is the production of a vacuum energy difference. The negative mass regime creates a rapidly changing boundary condition—effectively a relativistic perturbation in the vacuum field—which triggers the Dynamic Casimir Effect (DCE).

    The Energy Flow Mechanism: In this specific theoretical model, the negative momentum photons influence the vacuum within the cavity such that vacuum energy flows from the vacuum into the dynamic Casimir cavity, manifesting as real photons or heat.

    Dear Andrea
    I see your message to Gavino M: 07.01.2026 at 16:23. That you will soon publish watts per liter volume for Ecat.
    My question here is:
    May more supplementary technical matters of the Ecats be presented at the same time?

    Regards Svein

    Dear Andrea Rossi,

    You asked me to clarify:

    Out of World Question:

    1. Do you think NGU technology will work on worlds where the gravitational constant for that location is less than that of the Earth?
    2. If such a limitation exists, would a centrifuge-induced sensed gravitation allow for proper NGU operation?

    3. Will NGU technology work on:
    a. the Earth’s Moon;
    b. Mars;
    c. Venus;
    d. Europe?

    4. If NGU technology will not work in gravimetric fields lower than Earth’s field, can you swing the NGU around, like in a centrifuge, to approach the sensation of Earth’s gravity.

    Dear Dr. Rossi,
    eighty-three years ago today, on January 7, 1943, Nikola Tesla died. He was a socialist and a friend of Lenin and Stalin.
    https://www.reddit.com/r/EuropeanSocialists/comments/106om8k/stalin_on_the_death_of_nikola_tesla/
    A Friend of Lenin and Brave Adventurer
    Nikola Tesla – dreamer, inventor and the sole creator of the first practical procedures and apparatus for the production and use of the alternating current, who – alone – during his lifetime, changed the development and use of electricity throughout the world – from the direct current system to the alternating current system – which is now in use almost everywhere. Creator of AC generators and induction motors, without commutators and brushes. A pioneer in inventing, designing, building and operating equipment for the wireless transmission and reception of electric power, and thanks to this, the first person to successfully launch a vehicle at a distance from his station for the wireless transmission of electric power; the vehicle was a boat, which operated and was completely controlled by electricity transmitted by radio. Inventor and builder of the “Tesla coil”, developing electricity and ultra-high voltage current, he also became the most daring experimenter in this high-risk field of electrical research, becoming the first human being to pass millions of volts of electricity from his personal equipment through his body, scintillating with ultra-high voltage electric arcs.

    I hope you will follow in his footsteps.
    Best regards
    Urs Z.

    Dr. Rossi, a 100-megawatt ECAT reactor provides the same power as 40-50 wind turbines, covering several hectares. I imagine it as large as a five-story building.
    How big is it, approximately?
    A wind turbine has about 2,000 hours of effective operation per year (in windy Sardinia) and is considered the most competitive renewable energy source, with costs between 3.5 and 8 cents per kW.
    Consider that Italy purchases nuclear power from France at about 5 cents per kW.
    ECAT is by far the most cost-effective and environmentally friendly source.
    I can’t wait to see some photos of this ECAT reactor and hope for a global presentation.
