    This issue does not depend on me,

    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.

    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

    1. I am not able to answer
    2. I am not able to answer
    3. In Europe as well as in the whole Earth planet this issue does not exist; about other planets, I am not able to answer
    4. I am not able to answer
    Warm Regards,

    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.

    1. I do not understand what you mean: cen you rephrase ?
    2. Same as in 1

    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.
