    Hello Dr. Rossi,
    You can reach far more potential customers by using YouTube influencers. Especially those whose reviews you can trust; for Germany, I’d recommend https://www.youtube.com/@Akkudoktor/featured. Others can probably name similar ones from their own countries. This way, you can reach not just 100, but sometimes over a million people in the first round of the campaign.
    Best regards
    Simon

    JJ:
    Yes.
    Leonardo Corporation has registered the trade mark ” Ecat the New Fire ” and the model of the cat looking at the sun; the registration is in the Class of Goods encompassing all the products that are used in fields similar to that of the Ecat; the registered trade mark covers the name “Ecat” or similar, like E-Cat, even if separated from the words “the New Fire”, but refers to the same Class of Goods.

    Dear Andrea

    Axil has been philosophizing about how to present and explain Ecat to the public in connection with the global presentation.
    Here is my suggestion. Herein is also my recommendation for thorough 3rd party verification:

    ECAT GENERATORS HAVE NOW ENTERED NORMAL PRODUCTION.
    (If someone claims that they can convert ZPE (Zero Point Energy) into continuously usable electrical energy without corresponding conventional energy input, this is an energy technical discovery of historical importance.

    Therefore, any such claim must be proven with extensive checks, measurements and verifications carried out by independent competent institutions, like any other extraordinary claim with scientific scope.

    Since zero point energy is found everywhere and is free, its use could revolutionize the world’s energy production and energy use to the great benefit of humanity.)

    Leonardo Corporation now claims that, based on several patents by Andrea Rossi, they have constructed an electrotechnical generator that truly converts zero point energy into regular electricity.

    A whole range of sizes of this invention have now been produced.
    These have now been consistently measured and tested by several independent verification institutions.
    Their reports are attached.

    The reports show/confirm that the generators, that have been given the name Ecat, do not produce any forms of emissions of gases, substances or radiation.
    These can then, if desired, be stored in the same rooms as people use.
    Smaller units with low weight are easily moved but must be turned off during movement.

    The smallest “basic unit” produces 100 Watts and weighs approx. 250 g.

    A collection of 10 basic units that produce 1 kW has a volume of approx. 3.75 liters and a weight of approx. 2.5 kg. It will, in full operation for a whole year, be able to produce: 8,760 kWh.
    Units up to 10 kW are safety approved and certified for use as and possibly together with regular mains power in homes and industry.
    All connections to networks must be carried out by certified electrical contractors.

    The largest Ecats that have now been produced consist of xxxx basic units and produce yyyyy watt.
    More detailed descriptions and conditions are given in the technical annexes.

    What exactly is ZPE?

    If you ask this question to AI, you will probably get an answer that is more or less updated after our global demonstration in January 2027 has been thoroughly reviewed and commented on by several scientific institutions and universities. We therefore encourage interested parties to follow along there.

    What significance can Ecat have for individuals and society?

    (A relatively comprehensive list must be provided here)

  • Andrea Rossi

    PROF AND TO ALL THE READERS:
    I think so, but the real independent third parties will be the Customers: we will give priority for the delivery of the Ecat, to the list of Clients that have sent a pre-order, to the ones that will guarantee to send to at least 100 acquaintances of them recommending them to buy the Ecat and to send the same recommendation to other 100 acquaintances of them, and so on, do start an exponential diffusion based on the “vox populi”. Therefore, this is a message to all the persons that sent a pre-order: if you are able to recommend the Ecat, if satisfied after receiving it, to at least 100 persons, recommending them to do the same and so on with the same recommendation starting an exponential chain, please send copy of your pre-order here:

    Will be the global presentation corroborated by an independent and prestiggious third party ?

  • Calle H

    Dear Dr. Rossi,
    I am curious about the part load capability of the Ecat product to be introduced in the market in 2027. If I buy a 1kW E-Cat must the load be exactly 1kW? Or can I reduce the load to 600 W (without having to connect an external 400W resistor)?
    Kind regards,

    Dear Andrea

    All forms of approvals/certifications are just as important as the safety certifications already obtained.

    This concerns all the relevant use situations.
    Here, compliance with the regulations/requirements that Axil and Paul Dogshun have previously presented is of crucial importance.

    I asked my energy supplier/energy producer how much power I could deliver back with the spot market price as payment.
    The answer was 100 kW. This is a high figure for private consumers and could also have a major impact on a number of ordinary businesses.

    The problem may be that, as is already happening today under bright sunshine, the market price becomes negative.
    Then it would be beneficial to be able to automatically stop the export.

    An Ecat that is to be able to interact with the grid and possibly export electricity must have the necessary properties and certificates.

    Certified contractors will not be able to carry out connections without the necessary product certificates. Contractors will not undertake attempts at certification of fully manufactured units. This is up to the manufacturers. The contractor should only carry out “plug and play” at the plants, in a prescribed manner.

    Based on the existing safety certifications, the other necessary certificates will hardly be a problem that requires anything other than time to get in place.
    Such time aspects can be presented at the global presentation for conditions where approvals are not yet available.
    This will be easy to understand for any interested parties.

    However, it is a very important both energy technical and social issue that must be given great importance during the presentation.

    I have tried to point this out earlier:
    The fact that today’s very dispersed electricity users are now able to cover their own needs and can also supply the network with a surplus when their own needs are low will change the entire load on the cable networks.
    The existing infrastructure, which currently has a major capacity shortage, will therefore be more than sufficient to meet future needs.
    This will eliminate the current capacity crises that now apply to both low-voltage networks and high-voltage lines from central power generation.

    The fact that a short distance between consumption and production is achieved is something that all industries see as a great advantage.

    With Ecat, an EV can produce the energy it needs when it is in use in traffic. It can otherwise be connected to the local network and supply energy to both its owner’s home, the nearest neighbors and industries. This is the opposite of what is happening today.

    The voltage drop in the network is minimal when the distance between production and consumption is short.

    This removes many “bottlenecks” in an extensive energy network and removes the need for major expansions.

    New power-intensive industries such as AI and others can easily establish their own environmentally friendly Ecat plants without being dependent on available energy and network capacity.

    Ecat will remove the biggest obstacle that currently exists for power-intensive industries.

    Presenting these conditions should also be a task that the selected third-party verification institutions must be able to investigate and present in a qualified manner.

    Regards Svein

    It is important to instruct the worldwide demo marketing subcontractor to state emphatically that the NGU is not a LENR system. No fission or fusion reactions are involved in the NGU power reaction. This position serves to separate the NGU from decades of disparaging propaganda leveled at all LENR activities.
    
    This strong, strategic statement serves to protect the NGU product from LENR’s historical industry stigma. To ensure your worldwide marketing subcontractors execute this perfectly, the pre-demo instructions to them need strong and repeated operational emphasis.
    
    Subcontractors need to know what the technology is, not just what it is not. If they only say “it is not LENR,” the audience will immediately ask, “Then what is it?” What should they then say?
    
    Mandatory Marketing Positioning Directive for NGU Systems
    
    Core Positioning Rule
    The worldwide marketing subcontractor is strictly instructed to state emphatically and unambiguously that the NGU is not a Low-Energy Nuclear Reaction (LENR) system
    
    Scientific Boundary Lines
    To prevent confusion, all marketing assets, presentations, and live demo scripts must explicitly clarify that the NGU power reaction involves:

    No nuclear fission reactions.
    No nuclear fusion reactions.
    No isotopic shifts or nuclear transmutations.

    Strategic Rationale
    This definitive boundary is required to separate the NGU from decades of disparaging propaganda, skepticism, and regulatory hurdles leveled at the LENR field. We must position NGU as a distinct, novel category of energy technology, entirely separate from historical controversies.
    
    Mandatory Alternative Messaging
    When audiences ask how the NGU functions, subcontractors must pivot away from nuclear terminology and utilize the following approved messaging framework:
    
    Do not say: “It is an unproven or alternative nuclear method.
    ”Do say: “[Insert your approved scientific description here, e.g., ‘It is an advanced electronic/quantum field interaction system’] that operates completely within standard safety and non-ionizing guidelines.”

    Richard:
    We will give the same guarantees in use in the same cathegory of products. The Ecats returned will be refunded only if:
    1- the seals of the internal black box will be returned intact
    2- the Ecat returns without evidence that the instructions written in the Manual for Use and Maintenance has not been respected
    Warm Regards,
    A.R.

  • Andrea Rossi

    Axil:
    Thank you for your suggestions.
    Please allow me a correction: what you call “zero reading” is actually defined “background”: the reading is never zero, because everywhere in this planet there is at least 0.1 uSv/h, also in every house. The measurements in our case are always made comparing the background reading when the Ecat is turned off vs when the Ecat is turned on.
    Warm Regards,

    To effectively engage a demo worldwide audience, you must counter skepticism immediately by replacing words with clear, visual indisputable evidence. 99% of the worldwide YouTube audience won’t understand and/or recognize the tester who made the safety certification or even knows what that certification means. The worldwide demo is not the time to cuts corners and make assumptions.

    Live Demonstrations
    Real-time Geiger counter test: Place an active, digital Geiger counter next to the Ecat during operation to show background-level readings.

    Audience participation:
    Invite an audience member to hold the radiation meter to prove the results are not manipulated.

    Side-by-side comparison:
    Measure a known low-level radioactive object (like a banana or an old watch) next to the Ecat to contextualize the zero-reading.

    Visual Presentation Upgrades

    Dynamic overlay:
    Stream the live Geiger counter screen onto the main presentation projector so the entire room sees the data in real time.

    Certificate showcase:
    Display the official safety certification document on a slide right next to the radiation data.

    Animate the routine:
    Show a 30-second time-lapse video of your daily testing process to quickly prove your operational consistency.

    Reframed Scripting

    Ditch defensive language:
    Avoid saying “There are no radiations”; instead say, “The Ecat operates completely within safe, natural background environmental levels.

    Emphasize the certificate:
    State, “Our daily safety protocols are officially validated by our completed safety certification.”

  • Richard

    Dr Rossi,

    When Leonardo Corp and its licensee begin shipping finished ecat products to those of us who have placed pre-orders, perhaps as soon as January, will there be any kind of warranty or money-back guarantee that the product will perform according to its specifications? What options will be available for any ecat products requiring repairs or adjustments so as to meet those specifications? Thank you for your answers to these questions and best wishes for your success!

  • Andrea Rossi

    DrLG:
    This is what we do every day during our test: there are no differences between the emissions of the background and the emissions during the operation of the Ecat at any distance from it. By the way, the safety certification has already been made. There are not ionizing radiations from the Ecat.
    Warm Regards,

    Axil/ Dr Rossi, re ionizing radiation demonstration
    August 8, 2026 at 1:50 PM
    @2026-08-08 08:17 Svein

    Nuance: bring the test source in and out of range of the meter so you can see the meter continuously go from near zero to full test source reading, real time, continuously, to reduce credibility of claims that the meter was tampered with between readings of different sources.

    DrLG

  • Axil

    @2026-08-08 08:17 Svein

    One aspect of a presentation that is usually done for the E-Cat is to show that there is no ionizing radiation that is produced. Also, the demonstration that no increase is ambient radiation is produced. I beleive that this type of safety assurance should be done at the forthcoming NGU demo. There will be much speculation about how the NGU produces energy without using any fuel. It is best to head off all adverse speculation right at the beginning.

    The ionization demo should show that the equipment used is functioning properly by first show that a test ionizing radiation source will register on the testing equipment. Then show that the testing equipment does not show any readings coming from the NGU that is producing electric power.

    This strategy is highly effective for managing public perception. Presenting a fuelless technology that operates outside conventional paradigms will inevitably trigger immediate safety skepticism. Proactively addressing these concerns at the outset of the demonstration provides a strong foundation for building consumer trust.The proposed methodology follows precise scientific protocols for validation and public transparency:

    Establishing Instrument Functionality (The Baseline Control)
    A critical flaw in many public demonstrations is the assumption that a zero-reading on a meter means a hazard is absent, when it could simply mean the meter is broken or powered off.

    The Protocol:
    The demonstration must begin by introducing a known, mild, and safe ionizing calibration source (such as a piece of low-level thorium-doped glass, an old radium watch face, or a standard smoke detector americium-241 component).

    The Visual Proof:
    The audience must physically see and hear the Geiger-Müller counter or scintillation detector instantly spike when exposed to the control sample. This eliminates the “broken equipment” argument entirely.

    Measuring Ambient Background Baseline
    Before the NGU is activated, the testing equipment must be used to map the natural ambient radiation of the demonstration room. This establishes the structural baseline (typically 0.1 to 0.3 microsieverts per hour, depending on local geography and building materials) so that the audience understands what “normal” looks like in that specific environment.

    The Active Operational Test (Zero-Emission Verification)
    Once the NGU is brought online, throttled up to full operational capacity, and actively supplying power to a heavy electrical load, the sensor must be swept around the perimeter of the device.

    Sensor Placement:
    The probe should be placed directly against the NGU chassis, over the high-voltage inverter output traces, and near the generation core.

    The Target Outcome:
    The display must remain completely flat, matching the pre-established ambient background level exactly, proving zero statistical deviation.

    The Public Relations Advantage
    By executing this specific Control -> Baseline -> Active Test sequence, the NGU team creates an unassailable data loop. It transforms a passive technical claim into an active, verifiable safety assurance, successfully protecting the technology from adverse speculation that will undoubtable be produced by the demo.

    There will be at least one question from the audience about were the NGU energy production is coming from. I would recommend that this question be addressed proactively by including a oscilloscope trace of the raw power produced by the NGU that shows the high voltage spikes of the electrical power generated by the NGU accompanied by a brief mention that these power spikes are produced by the extraction of power from spacetime.

    Thank you for your opinion,

  • Svein

    Dear Andrea

    I do not see a divergent goal between what I claimed and what you recently presented.
    The basis for information to the world about your product and its effectiveness must be 100% based on real facts.

    That the product performs what is presented and is legal to use, a consumer probably takes for granted, since that is how civilized societies are organized.

    That I presented scientific acceptance as the main goal, was only because your commercial goal could then be met much more easily.
    (When you are going to walk or run, there are no regulations about which foot you start with, the other foot undoubtedly have to follow.)

    Regards Svein

  • Andrea Rossi

    Svein:
    Thank you for your suggestions, but the main goal of the global presentation is not to get scientific acceptance, the main goal is to inform the world of the product and its efficiency; scientific acceptance will be a logic consequence of a matter of fact [like the flight of the bubblebee (he,he,he)],
    Warm Regards,
    A.R.

  • Svein

    To all followers of JoNP.

    The global presentation in January 2027 has an obvious main goal in gaining scientific acceptance that Ecat is able to extract and convert energy from ZPE into a form of energy that we can easily use.

    This has a great deal of similarity to the fact that solar cells were developed with the ability to convert sunlight into electricity.

    A main problem for Ecat is that ZPE is not a form of energy that humanity is already familiar with.
    This significantly increases skepticism among both laypeople and technologists.

    By showing that there is an energy flow coming out of Ecat, it is probably the easiest way to gain acceptance that there must also be a real energy flow coming into it from some form of energy source.

    There have been quite a few suggestions about finding the most eye-catching way to present this.
    The demonstration in Latina in 2024 was met with little attention from technologists and science.

    It has been announced that third parties that are well-regarded control and verification institutions for such energy-technical matters will present and document exact numerical energy emissions from Ecat devices.
    This will probably be crucial to gaining general scientific attention.

    Energy from ZPE will pose a devastating threat to today’s energy sources.
    This will likely result in significant “attacks” from their owners to prevent the use of Ecat generators.

    Producing electricity from renewable and energy-efficient sources is a central part of most countries’ governments’ strategies to tackle climate change.
    The introduction of a proper commercial and regulatory framework is the most important factor in how grid operators can support the authorities’ goals of renewable and energy-efficient production.
    This will be the largest and safest basis for the introduction and use of Ecat.

    In those nations that are dependent on imported hydrocarbons to maintain their electricity supply, politicians will most quickly ensure that resistance to Ecat is eliminated and that Ecat is used to improve the country’s business and economy through cheaper and environmentally safe energy access.

    It therefore seems important to ensure that all formal requirements for the use of Ecat are met precisely in these nations.

    Suggestions on how this can best be met is a challenge that I would like to ask all followers of JoNP to contribute to.

    Regards Svein

    Dear Andrea Rossi,

    How about adding an ordering option for the positive and negative leads of DC output of the NGU units supplied with MC4 connectors? These are the same connectors used on solar panels. This would facilitate tying units in serial and the unit or units being used just like a solar panel.

    Another Ecat+inverter installation hurdle to jump in the UK.

    The problem is whether to buy an Ecat+inverter before or after the Ecat+inverter is added to the ENA Type Test Register[1:]. If the Ecat+inverter is not added to the register by the manufacturer and then approved, then it cannot lawfully be installed and operated with a grid connection in the UK. The best solution I can see is to forget the ON-grid connection and install an OFF-grid inverter+battery with a break before make changeover isolator.
    This avoids synchronizing and bureaucratic/legal problems but might increase the possible Ecat peak loads.

    The UK legal limits are laid down in the G98, G99 and G100 codes[2:] and inverter users will be required to prove they are compliant before connection to the grid.

    [1:] https://connect-direct.energynetworks.org/device-databases/search-gen
    The ENA Type Test Register
    An application must be submitted every time an installer or customer wishes to install a [Ecat], Solar PV system, Battery, Electric Vehicle Charge Point or Heat Pump on an existing property.
    All Connect Direct applications must be made pre-installation.
    Connect Direct uses a data-driven decision engine to assess applications.
    It checks things like:
    The safety of the cut-out and supply equipment
    Whether the supply capacity is sufficient
    Whether the property is on a looped supply
    Whether a network upgrade is required
    The Maximum Demand of the property is within DNO thresholds
    Equipment compliance
    Whether the equipment within DNO-defined approval thresholds
    If all checks pass, the application is auto approved in real time. If not, it is escalated to the DNO for review. Any updates will be communicated to you via Connect Direct.

    Dear Dr Andrea Rossi,
    If either Leonardo Corporation will start the deliveries of the Ecat SSM, or of the Ecat not SSM, if laymen will receive a generator of electricity or of heat with COP infinite ( in case of SSM) or COP 5, if non SSM, it will be a miracle: if it will happen within January 2027, as you said you hope, it will be the most important event of the last 100 years.
    I am a pre-order guy, and I think that the hundreds of thousands of guys that sent a pre-order share my opinion.
    We all will be the witnesses that, after receiving your masterpiece, will diffuse exponentially the wonderful news of thousands of Ecats that make a miracle for real in our houses, offices, workshops and industries.
    I sent minutes ago to info@leonardocorp1996.com copy of my pre-order, to give you proof of my word.

    I’m very happy to hear that an ac/dc switch will be added to the 100w ecat. Will there be a gage to indicate how many watts are being drawn from the ecat. For example if a 100w ecat has 3 10 watt led lights drawing from the ecat and then I charge a cell phone, will there be an indicator letting me know how many watts are being used? I think this will be important whether for a 100w unit or a 1k assembly.
