    I Well remember the first days of E-Cat, back in the 2000’s when The earlier experiments were done, I was full of enthusiasm, I feel now the same,”m preparing to spread E-cat revolution, but in the earlier 2000’s I was still smocking, now i am in the edge to start again in this hours due to the stress…

    Dear Andrea Rossi,

    Consider the following System.

    One EG4 12kPV Hybrid Inverter – cost $3,500 USD. – No Battery system – see their online spec sheet.
    Four 2kW NGU Power Generators – each configured to output 240VDC @ 8.33 Amps.

    The EG4 12kPV has 2 MPPTS and each MPPT can accept 2 inputs.

    The System would continuously generate approximately 8 kW which could be directly tied to the Grid to sell power back to the Grid.

    Costs:
    1 EG4 12kPV costs $3,500 USD
    4 2kW NGU Power Generators will cost $20,000 USD.

    Assume a Grid payback of $0.09 per kw-hr.
    8kW will earn $0.72 per hour.

    Payback time = $23,500 / $0.72 = 32, 639 hours or 3.72 years if only Grid sell back is used.

    Assume residential full rate of $.20USD per kW-hr if the entire 8 kW is consumed in lieu of Grid power. then:

    Payback time = $23,500 / $1.60 = 14, 688 hours or 1.68 years.

    Thoughts?

    Followers of the E Cat saga must be awaiting with great excitement the report of May 7th by Dr. Rossi. We do not know what this report will be but personally I hope and expect it may be connected to a final undeniable and unstoppable entry of clean limitless energy into the world markets through E Cat technology and any subsequent developments. The scientific stooges of the oil industry may have derailed the original 1989 cold fusion breakthrough, and labelled the field as ‘pathological science’, but maybe that just makes many of us believers into pathological personalities. The E-Cat technology is not cold fusion but no matter, the cold fusion breakthrough was the seed, from which the mighty E Cat tree, and worldwide forest, will soon, god willing, grow. Human greed and wickedness may have prevented many clean energy technologiues from reaching fruition in the past and the reward if those malign actors is a planet on the precipice of natural destruction. To go one further, perhaps Dr Rossi, and those of his ilk, are in a sense angels sent by the Lord, to save humanity from itself.

    Mailing with my Boss, Mr. Thacker, Ara Partners:

    Dear Mr. Thacker,
    Your company Ara Partners is the owner of my employer, Vacuumschmelze GmbH in Hanau (Germany).
    The goal of Ara Partners is to drive industrial decarbonization in order to make the economy less carbon-intensive. To this end, Ara Partners invests in companies and infrastructure.
    You may be familiar with the efforts to decarbonize energy production with the cold nuclear reaction (LENR).
    Here is a NASA report:
    https://coldreaction.net/get_file.php?id=34820005&vnr=482807
    Will the market launch succeed in 2025?
    https://lenr.wiki/index.php?title=Zur_geplanten_Markteinf%C3%BChrung_des_E-Cat_im_Jahr_2025
    If the market launch succeeds, it would be a huge step towards decarbonization.

    I would be delighted to hear your views on the subject.

    Answer from Mr. Thacker:
    Exciting technologies, but they are still a long way out. Too long to fit within our typical investment style, so I don’t track them closely.

    What would be the appropriate response?

  • Calle H

    Dear Dr. Rossi,

    Some time ago you advised us not to spend time and money on design and engineering work for our E-Cat applications. I understood this was because the Data Sheets and other information will be subject to changes. Will you announce a date when it’s time to start our work?

    I would also like to ask for your thoughts about showing the E-Cat in action in a practical application. The E-Cat in a practical application has been lacking so far. I think it would give a kick to designers, engineers and buyers for placing volume orders. I believe volume orders are what Leonardo would like very much. Volume orders are needed to distance to competitors who are desperate to catch up. Thank you if you can answer.

    Kind regards,
    Calle H

    Ron Stringer:
    Thank you for your kind support.
    When we will retrieve the old piece to deliver the new one, all of the old piece will be recycled.
    Warm regards,
    A.R.

  • Ron Stringer

    Dear Dr. Rossi,
    Looking forward to your report on May 7! In the meantime, I have been thinking about your policy on recycling the E-Cat. The policy to make a replacement available for half-price is brilliant, and should bring lots of used units back to the factory.
    You have mentioned that the E-Cat will be completely recyclable – can you explain that a little bit more? As I see it, there are the casings, which will be plastic, I presume, then the connectors and wires, electronic components, PCBs, and the reactor itself. Complete recycling is a tough goal – how much will be reused? Can the reactor be put back into use?
    Complete recycling should put the E-Cat ahead of many competitors and win support from regulators and governments – recycling old solar panels and wind turbines has proven to be very problematic.
    And also it is the right thing to do!

    Dear Dr. Rossi

    after the “disruptive” demonstration of the Ecat-EV in Latina (by the way, thanks again for giving me the opportunity to “give my contribution”), I can’t imagine what kind of technical evolution you will be able to achieve on your E-cat.

    I am very curious to know the Details, kindly keep us updated.

    Inertia in power systems refers to the energy stored in large rotating generators

    As the grid evolves with increasing penetrations of inverter-based resources—e.g., wind, solar photovoltaics, [SKLep] and battery storage—that do not inherently provide inertia, questions have emerged about the need for inertia and its role in the future grid

    this report provides an overview of inertia’s role in maintaining a reliable power system, why inertia may decrease with increasing deployment of wind, [SKLep] and solar generation

    Using power electronics, inverter-based resources including wind, solar, [SKLep] and storage
    can quickly detect frequency deviations and respond to system imbalances.

    Using power electronics, inverter-based resources including wind, solar, [SKLep] and storage
    can quickly detect frequency deviations and respond to system imbalances.

    7.3.3 Dispatch of Inverter-Based Resources
    For solar and [SKLep], the inverter can be commanded to reduce and then rapidly increase output via the use of power electronics. This operation reduces the amount of energy generated, so results in an economic tradeoff between providing energy and providing the ability to respond to imbalances.

    These microgrid systems may employ one of the inverters to provide the master voltage and frequency waveform (grid-forming), with others acting in grid-following mode (Figure 20b).

    https://ieeexplore.ieee.org/document/9513281
    Microgrids, which can operate in the grid-connected mode as well as in the islanded mode, emerged as a platform for integrating IBRs [2]. In the grid-connected mode, voltage and frequency are regulated by the grid, and thus, IBRs simply operate as grid following inverters. In the islanded mode, one of the inverters, or a couple of them, should function as voltage and/or frequency regulator(s) to form a local power grid.

    Do you think that SKLeps could perform well in a microgrid with the necessary inverter(s) in both grid-connected and islanded modes?

  • Dear Andrea,

    Dr. Rossi,

    Elon Musk says on X: “My prediction is that in the long term, 90% or more of all energy on Earth will be supplied by solar panels with batteries.”

    Maybe is he wrong?

    Dear Dr. Rossi,

    The E-Cat NGU with its isolated software could save us in the near future from intrusive, external AI systems.

    (Sorry if this prediction puts additional pressure on your march toward production success).

    According to current observation of AI progress, AI development is not slowing down and is not required to have built-in safety protocols.

    AI might be progressing too quickly?

    https://youtu.be/uMwjKyAPR34?si=f2fvL8461lKjf7Ys

    Here is a thoughtful video on AI progress from one year ago.

    https://youtu.be/brQLpTnDwyg?si=Z7TuVCC_wuI_BNN6

    Please tell me that you will consider producing the E-Car NGU as a private, isolated box with no Internet nor Wi-Fi broadcasting connections?

    Best Regards,

    Daniel G. Zavels

  • Steven Nicholes Karels

    Dear Andrea Rossi,
    Yet another application of NGU technology – Deep Underground Mines

    “A deep underground mine consumes a significant amount of electricity, typically ranging from 9 MW for a small gold mine to 180 MW for a large copper mine. This power is used for various operations like ventilation, lighting, and powering machinery. Deep underground mines also face challenges related to ventilation, lighting, and the management of dangerous gases, which further contribute to the high electricity consumption.”

    Remote location far from the Grid. 24-hour continuous demand. Sounds ideal for NGU!

    In condensed matter science, a quasiparticle is an emergent phenomenon arising from interactions within a many-body system. It effectively describes the collective behavior of many interacting particles, simplifying the complex many-body problem in quantum mechanics.

    For instance, an electron in a solid interacts strongly with its environment, including other electrons and ions in the lattice or a plasma. This interaction “dresses” the electron, effectively modifying its properties such as its mass and charge, creating an electron quasiparticle.

    The modified properties of these ‘dressed’ electrons (quasiparticles) allow them to behave differently than free electrons, leading to phenomena like coherence, clustering and collective behavior. For example, an electron quasiparticle in a solid might have an effective mass and/or charge that differs significantly from that of a free electron.

    A quasiparticle mechanism can renormalize the mass and charge of the electron. Composite fermions, formed in two-dimensional electron systems under strong magnetic fields, are another example. Recent research shows that in materials like twisted bilayer graphene, electrons can behave as quasiparticles carrying fractional amounts of the electron charge, allowing them to form unusual aggregates or clusters.

    Key examples of electron-based quasiparticles include polarons: an electron surrounded by a cloud of polarized ions; holes: the absence of an electron behaving as a positively charged quasiparticle; and excitons: a bound state of an electron and a hole.”

    In essence: The concept of quasiparticles helps physicists understand and model the behavior of complex many-body systems by effectively simplifying the interactions and treating emergent excitations (like dressed electrons) as quasi-independent entities with modified properties.

    In the next revision of Dr. Rossi’s theory paper, I hope he pays more attention to the role that quasiparticles play in his invention and takes time to include the description and role of quasiparticles in his presentation.

    Dear Andrea Rossi,

    Yet another NGU application – powering Steel production plants.

    “A steel plant’s annual steel production can vary greatly, from as little as 50,000 tons to as much as 3,000,000 tons per year, depending on the plant’s size and type. Typical minimills produce between 200,000 and 400,000 tons annually.

    Electric arc furnaces (EAFs) in steel plants have high electricity demands because they use electricity to generate the high-temperature arc necessary for melting steel scrap. This process requires a substantial amount of energy, typically around 400-500 kWh per ton of steel produced. The power requirements can be very high, with some EAFs consuming up to 200-300 MVA (megavolt-amperes).”

    400 kW-hrs per ton * 200,000 tons per year = 80,000,000 kW-hrs per year. Or 9 MW of continuous power.

    Thoughts?

    In data center management, the concept of “lights-out” operation refers to a highly automated environment where non-technical personnel are alerted electronically to hardware failures. Upon receiving a notification, personnel retrieve the necessary replacement part from inventory and proceed to the specified location, guided by visual indicators such as a blinking red light on the failed device. The expectation is that replacement can be performed with minimal tools and without the need for specialized technical knowledge.

    I propose a similar operational model for the maintenance of E-Cat arrays. Specifically, I am evaluating the resilience and maintainability of E-Cats for mission-critical applications where system uptime and rapid serviceability are paramount. Key considerations include the operational environment—whether E-Cat units should be co-located within the data center alongside IT infrastructure under controlled (air-conditioned) conditions, or isolated externally in modular enclosures such as shipping containers to simplify thermal management and reduce potential risks.

    Releasing detailed specifications on thermal output, noise generation, serviceability protocols, MTBF, and failure modes will be critical to fully assess ECat’s suitability for integration into mission-critical environments.

  • Gianvico

    Good morning Andrea
    assuming that:
    the E-Cat seems a fairly complicated mechanism;
    you will have to produce hundreds of thousands of E-Cats monthly;
    it takes a couple of years to build a factory, all the more so if it is automated
    all of the above means that years you have started building the factories, otherwise next year’s deadline is humanly impossible to meet.
    Gianvico
    PS: very happy to be wrong

    Good work.
