    There is a temporary diminution in the interest in EVs, due possibly to high prices and/or the potential for tremendous, difficult to extinguish battery fires. The SKL battery charger, allowing much smaller batteries, is need now.

    Cities are considering/have banned EVs from underground garages due to the risk to the structures above.

    Not to worry! I have suggested that chemical flow batteries, and electrolyte exchange stations, where you pull in and exchange your electrolyte for recharged fluids, be installed as soon as the technology matures.

    Hopefully you will complete the SKL reveal prior.

    @ Gerard McEk,
    The heat pump in my house use the outgoing ventilation air as heat source. In Swedish “frånluftsvärmepump”. Therefore the COP is constant as the ventilation flow is constant and the house temperature is constant 20 C. Hot water supply is 55 C. The advantage is that there is no temperature dynamics in the pump operation. The disadvantage is the limited avaliable heat, in my case 4 kW. The price 8,000 USD is the completet installed unit including water tank and controls. This is a common installation in Nordic privat houses.
    Kind regards,
    Calle H

    @ Calle H :
    The COP of 4 for a heat pump is only so high if the medium of which energy is extracted not too cold. Most heat pumps extract heat from outside air. If the temperature drops below 10 degrees the COP starts to drop as well and at -5 C it’s usually around 1. From that moment you are only heating your house with electricity in a very expensive way and I would recommend using a simple electrical heater under those circumstances.
    This all makes the Ecat SK quickly more competitive when considering the choice Ecat SK or heat pump.
    Also: At this moment heat pumps cannot heat water over 50 degrees at a COP of 4 so they are not a simple exchange to a central heating boiler with radiators. I guess that also makes the SK more competitive.
    In comparison with a standard heating boiler, the SK should be competitive if its price is around 2000 € and has a COP of 4.

    Dear Andrea,

    You mentioned “We always try to replicate all the patents directly or indirectly related to our work”, your ResearchGate paper
    http://www.researchgate.net/publication/330601653_E-Cat_SK_and_long_range_particle_interactions
    cites in reference 38 the Josef Papp patent US3670494 of 1972, do you or your team feel it is possible that a particular aspect of this patent may be physically investigated / tested / replicated?

    Regards,

    Keith Thomson.

    Dear Andrea,
    I believe it is an excellent move to introduce the Ecat SK as a reliable product to produce heat.
    1. I recall that maybe two years ago you installed some of these at a customer. Are these still in operation?
    2. Will the basic building block, the singel Ecat SK have an output power of about 20 kW, so being suitable for most houses to supply heat and hot water during cold winters?
    3. The output power can be modulated by switching the SK on and off?
    4. Is the COP still in accordance with the https://www.researchgate.net/publication/330601653_E-Cat_SK_and_long-range_particle_interactions -document stating around 50, so for 20 kW heat output, you would need about 400 Watt electrical power?
    5. I think with that specification you would have a gigantic customer base. Will you introduce it also in November 2021 as a product, like the lamp?
    6. No doubt you will continue the research on the SKL. Would you skip the introduction of the SK if you would succeed in making a reliable SKL?
    I wish you all the success and hope I can soon also buy an Ecat SK for heating my house.
    Kind regards, Gerard

  • Jitse

    hello Andrea Rossi,

    1 Are the results of the ‘ecat sk’ such that it can be certified, or is the ‘sk’ already certified and commercially available for sale to your customers?
    2 I use approximately 1500 m^3 natural gas per year to heat my house, which I would prefer to reduce to zero.

    With Renards
    Jitse

  • Ludwig

    Dr Rossi:
    I understand after watching the presentation of the Ecat SK here
    http://www.ecaskdemo.com
    that the SK is given only for industrial utilization of big plants and the Ecat SK plants remain of Lronardo Corporation’s property, while Leonardo sells the thermal energy generated by the Ecat SK.
    Am I correct ?

  • Calle H

    Dear Dr. Rossi,
    The progress of the E-Cat SK is very exciting. May I ask a question from a personal experience point of view. I have a heat pump in my house for providing tap hot water and for space heating in the winter. The heat pump (4 kW) has a COP 4.0 (heat output/electricity input) and is a considerable investment (8,000 USD) for a relative short life time (typically 8 years to compressor breakdown which is the most common problem).
    – Is the COP of the SK greater than 4.0?
    – Is it likely that the price for the SK will be less than 8,000 USD for 4 kW capacity?
    If the answers are yes, the heat pump market will soon be dead.
    Best wishes,
    Calle H

  • The Quiet Wine Guy

    Dear Andrea,
    I think your upgrading the Ecat SK with all lessons learned from the SKL, such as a much improved control box, is excellent news that I’m sure brings a sense of pride to Team Rossi and you.

    Previously, in late 2019, October 7th to be exact, you shared that there were in excess of 5 Ecat SKs installed.
    Is it reasonable to recognize that these “old” SKs will be replaced by the updated SK’s, given that the customers will receive a greater benefit? As well, are all of these customers pleased with their current SKs and to receive these “more potent” SKs? Finally, given the move of Leonardo Inc. towards a more significant, more business oriented introduction of the SKLed with its “hurdle” of 1 Million pre-orders, will some of these Ecat SK customers be part of the November 25, 2021 presentation to add weight to the message of “The Ecat SK/SKL family of products is here”, driving your goal of rapid and broad global deployment?

    Again, my congratulations. This is wonderful to see in my lifetime.

    Sincerely and Respectfully,
    The Quiet Wine Guy

    We wait with bated breath the success of you and your team in applying the ECat SKL
    to battery charging. Even now governments are considering banning todays oversized
    EV batteries from underground garages.
    https://www.motorbiscuit.com/fire-danger-underground-parking-lot-bans-electric-vehicles/
    If we, collectively, knew more of your challenges, the great minds following you (not mine)might
    be of use to your problem solving. One idea, not so innovative, is to allow the electron
    or photon bursts from the radially expanding reconstituted proton to impinge on the fluid
    of a flow battery. Zinc-bromine and alternately Vanadium have been used for the electrolyte,
    but it should not be difficult to find a species that undergoes a Redox reaction from photon impact.
    This assumes the SKLed is inside a quartz tube with the fluid outside, cooling the tube as
    it is pumped past. If electrons… well we do not know enough of the SKL to speculate,
    but you DID say bright light.

  • Steven N. Karels

    Dear Andrea Rossi,

    Let me attempt to be more exact…

    You posted “Then we have the Ecat SK, that makes heat, along this
    http://www.ecatskdemo.com
    and finally we have the Ecat SKL, to make electricity, that is still in the making of the R&D process, as promising as it might be.:

    Is the Ecat SK (that makes heat) a derivative or subset of the Ecat SKL or Ecat SKLed or is it an entirely different product than the Ecat SK or Ecat SKL?

  • Steven N. Karels

    Dear Andrea Rossi,

    I think I recall in the early days of what became or will become the SKL, you mentioned that you could control the percentage of heat versus electricity generated.

    1, Is this basically correct?
    2. Is the SK Lite an SKL optimized for heat generation?

  • Svein H. Vormedal

    Dear Andrea.
    I have many light sources in my house that are of great design importance.
    I keep the heat from these, as most of the year there is a need for space heating.
    What I could now wish for is an ecat SK that I can put between my panel oven and the power outlet in the wall.
    I also want to use a similar one for my water heater and in connection with heating cables in concrete floors.
    I envision a device that delivers approx. 2kW.
    In a normal home, there will probably be a need for at least 4 of these. It will be much more for me to save here than with an ecat LED.
    There will also be no design challenge in using such.
    When can we get more information about such a device?

    Regards,
    Svein H. Vormedal

  • Chuck Davis

    Dear Andrea, I would love to have an SKL that I could integrate with my electric furnace to provide the necessary heat into the heat chamber and disable the resistive elements and use the house thermostat to control the ecat. Heating is my largest load. I purchased an all electric home with the intent of installing the ecat when it becomes available. However if I could heat with an SKL that would be a major improvement.

    Warm regards,
    Chuck Davis

  • Andrea Rossi

    Frank Acland:
    It will be for any scale, from domestic to industrial, but I think it is more proper to call it SK. The SKLed makes light, the SKL makes electricity.

    Sailmenn:
    As I said, the SKL heat is the SK. We can reach any power, just assembling modules from KW to MW orders of magnitude,

    Dear Andrea,

    Regarding your plans for the SKL Lite heating product, will it be of industrial size, or suitable for domestic heating?

    Dear Mr. Rossi,
    sorry for pester you again 😉
    I thought an ecat SKL light/lite would produce ohmic load, therefore electricity just for the use with f.e. an oil-filled radiator, lightbulb or an hot-water boiler.
    But you answered to Mr. Acland it will not produce electricity. So will an e-cat SKL lite be integrated in electric heating usages, analogous to the SKLed?
    Warm regards
    Ernst

  • Patrick

    Dear Andrea,

    How is the SKL(heat only) different from the SK?

    Best regards,
    Patrick

  • Tom Conover

    Dear Andrea,
    I was puzzled for a few minutes about your current direction of using the SKL to produce heat. I thought that I preferred electricity, but after a 30 minute discussion with my pc I found the link below which reminded me why heat is a more efficient use for the SKL output. It takes awhile to go through enough of this web page to reteach anyone who is still electricity biased vs heat biased (like I was) but if you take the time to review this for awhile you will be adjusted to the point of view that producing heat is more valuable than producing electricity. etc etc etc

    Warm Regards
    Tom
