    Dear Andrea,

    I’m thinking of building a system with these characteristics:
    – 1 Ecat MiniSKLep (AC In – AC Out) connected to the grid
    – 3 ECat SKLep (AC In – AC Out) powered by Ecat MiniSKLep
    Might it work ?

    Best

    Roberto:
    Thank you for your kind attention to our work. Actually, no money has changed hands and no money will change hands until we deliver. We have been clear on this fact as well as we have been clear that the pre-orders can be cancelled anytime from our Clients in case they change idea, whatever the reason.
    This said, I prefer to answer to all the comments, for respect toward our Readers, unless the comments are sent by trolls: our system automatically spams comments arriving from trolls’ sources
    Warm Regards,
    A.R.

    Martyn Aubrey:
    All we need is a connection with the grid, 110 or 220 V as it might be.
    Special situations will be assessed at the delivery.

    Dear Dr Rossi,

    Congratulations on releasing the 10W MicroEcatSKLep.

    Which of the input power connection configurations will work with this device please?

    1. 3 pins: 220/240v mains live, neutral and earth.

    2. 2 pins: 220/240v mains live and neutral only.

    3. 3 pins: Mains derived 12vDC +ve, -ve, and a grid connected earth connected to the AC/DC adaptor.

    4. 2 pins: Mains derived 12vDC +ve, -ve, but with no earth connection, using a 2 conductor mains cable from the AC/DC adaptor to the grid.

    5. 3 pins: Battery derived 12vDC +ve and -ve, but with the earth connected to a mains grid supplied earthing point.

    6. 3 pins: Battery derived 12vDC +ve and -ve, with the earth connected to an independent earth spike hammered into the ground.

    7. 2 pins: Battery derived 12vDC +ve and -ve, with no earth connection.

    8. 3 pins: Mains derived 12vDC +ve and -ve, but with an earth connected to an independent earth spike hammered into the ground rather than connected to the grid mains earth.

    Thank you if you can answer.

    Good luck for achieving your aim of 1 million certified orders this year.

    Kind Regards,
    Martyn Aubrey

    Dear Dr Andrea Rossi,
    I am very disappointed to read in this blog comments saying they are disappointed because the Ecat SKLep and the newborn Mimisklep need a grid connection; these guys probably do not know what they are talking about, or worse: I don’t understand if they are naive or smartasses. You are introducing a device that generates Watthours and consumes zero Watthours, but they say they are disappointed, because you need a grid connection…why do you lose your time to answer these guys ?
    If they are disappointed they can just cancel their preorders, as you already responded some of them.
    Don’t waste time to answer, just conserve it for your tremendously difficult task.

    Dear Andrea,
    I just received the confirmation email for the 4 Mini SKLEPs I ordered. Of course, if they could disconnect from the electricity grid it would be more advantageous but, probably, it would make the owners of the grid nervous.
    Regards, Giuseppe

    Dr Rossi,
    I want to congratulate for the very interesting Mini-SKLep.
    I wish you and your team the success that your monumental work, now 12 years long, merits.
    Ad majora,

  • Gavino Mamia

    ora che hai detto che SKLep funzionerà solo connesso alla rete temo che avrai molte cancellazioni. non si spera più di raggiungere il milione
    forse non mi servono nemmeno più così

    now that you have said that SKLep will only work connected to the network I am afraid you will have many cancellations. it is no longer hoped to reach one million
    maybe not even serve me like that anymore

  • Martin

    Dear Dr. Rossi.

    My application is a mobile (Camping-)Application.

    This would require an Ecat, which can be fed (Input 12VDC via 12V-car-plug or 230VAC via inverter and plug) from the car’s battery.

    Questions:

    1.) Is this possible with Ecat SKLep 100W, you offer now?

    2.) Is this possible with Ecat MiniSKLep 10W, you offer now?

    Thanks for your answers.

    Best regards, Martin

  • Gerard McEk

    Dear Andrea,
    On ECW there is a lot of discussion about the fact that the SKLep (100 or 10W) cannot operate properly on a battery.

    I have suggested the following on ECW, maybe it will help you:
    “I would suggest that perhaps a grid level voltage that causes a slight ‘leak’ current that might run though the capacitance of the Power Supply Unit (PSU) is needed to drive the process in the reactor (if any). That current may then run from the grid via this capacitance and the reactor to earth.
    Usually it will only be the ‘higher than grid frequency’ harmonics currents that will run there.
    To check that, AR should use a highly insulated PSU, where the primary and secondary windings are properly screened by an earthed screening wire and preferably these windings should also be physically separated (not on top of each other as is usually done). When using such a PSU, the reactor wouldn’t work anymore. Once that is known, an electronic generator device can be build that will make the reactor work under all circumstances, including on a battery.”
    One additional question:
    You once said that the SKLep will operate on a battery, but not in SSM. If that is true, will the COP of the SKLep then still considerably larger than 1?
    Thanks if you can answer.
    Kind regards, Gerard

  • Dear Andrea,
    >will decrease gradually until the power of the grid resumes
    What about having two devices producing AC in antiphase and simulating the grid for each other?
    (An intuitive thought for further development, not supposing that it would work directly with the current setup…)
    regards, /pekka

  • Vanessa

    Dear Mr. Rossi,

    I would like to ask one more question:

    If ECAT SKLep is powered by battery, then:

    1) ECAT SKLep does not work at all

    2) Electrical output of the ECAT SKLep is less than or equal to the electrical input

    3) Electrical output of the ECAT SKLep is higher by 30% or more than the electrical input

    Have A Nice Day

    Dear Andrea,

    While waiting for an engineerd 1kwh unit, could you not simply propose a 1kwh unit that is assembled from 10 x 100Wh units ? I think of a larger rugged box with two handles that still can be moved around so as to be connected for instance to my car in the garage during late night time (allowing recharging of 10Kwh in 10 h which would give 50 km autonomy).
    And which would allow to support energy consumption my appartement during daytime ? An integrated 230V inverter & power exit cord would be ideal so as to have a low barrier to entry. All a buyer would need is the installation of a charging point in his electric grid. For that too there should be an visual explanation in your commercial website so that he can show it to an electrician.
    I think that kind of unit would speak to many potential customers. It would be much more practical then to have a cable salad dangling from your ten 100 Wh units laying on the floor.

    The charge of 50km a day assuming 20Kwh consumption would allow for 18.250 km driving a year. The 10kwh/day x 365 days =3650 Kwh/year is at a marketprice of 35 cent to 70 cents (maybe soon in europe) anywhere between 1277 Eur and 2550 Eur. So payback for car charging alone is 1 to two years. When you ad daytime use (24h – 10h car charging) of 14h that gives you another 5110 Kwh which should easily cover your household electric consumption (if not heating electrically) best with a buffer battery.

    1) Could you short term envisage building this kind of 1Kwh charge box sold for example for 2999 Eur inverter included ? Maybe with a seperate 2-3 Kw battery as option ?

    2) make a demo film of a 24h cycle described above to convince customers ?

    Crossing fingers to reach quickly the 1 million threshold (or 100.000 x 1Kwh box threshold).

    Best,
    Michael S.

  • Mark

    1) When I placed the order for sklep we can use a battery for input, now need connected to the grid?
    2)In the website in possible application there was something about 80sklep can provide energy to a vehicle. Now disappear?
    3) Something change before beginning?
    4) the grid requirements is for respect law?
    5) to respect the law you have to put a safe method to unplug system, like assisted electric bicycle (different from total electrical)

    if all yes I think I understand why “changed”

    Dear Dr. Rossi,

    I noticed you updated the Minisklep specifications to include the requirement that it be grid connected.
    I not sure what this means, so I will ask some questions.

    Question 1
    Is a single ground wire sufficient to meet your requirements for a grid connection?

    Question 2
    Assuming your answer to question 1 is no
    Are 2 wires carrying 120VAC sufficient to meet your requirements for a grid connection?

    Question 3
    Assuming the answer to question 2 is yes
    If I substitute a battery and an inverter that outputs 120VAC for the grid connection would the Minisklep continue to function?
    A) no
    B) yes
    C) I haven’t tried it yet

    Warm Regards,
    Dan Galburt

  • Mirco Romanato

    Dear Dr. Rossi, I’m thinking about the requirements to run the SKLep and miniSKLep at home;
    what should we expect in the case of a blackout of the grid, if we are using the SKLep(s):
    1) will they graciously fail and just stop working until the power of the grid resume?
    2) will they continue to produce energy even with the grid down?

    I plan to connect the SKLeps (connected to the grid, of course) to an hybrid inverter (something with a configuration similar to this https://amz.run/5uQQ ); basically swapping the solar panel with the SKLeps.
    3) Did you or someone else tested this idea?
    4) Did it work?

    I hope you will get to your target as soon as possible
    Best regards.

  • Karl-Henrik Malmqvist

    Dear Andrea,
    The Ecat SKLEP specifications says the input is 12 V DC. From your blog we have learned that the input must come from a grid-to-DC adapter. When asked why, the answer is confidential.
    a) Have you made many tests with different types of AC-to-DC converters? The older ones have just a transformer with a rectifying bridge while the newer ones are high frequency switching devices.
    b) Will all types of AC-to -12 V DC adapters work?
    c) All adapters have an internal capacitor to smothen the output voltage. Is it OK to add an external big capacitor in parallel before feeding the 12 V to the Ecat SKLEP ?
    Best Regards,
    Karl-Henrik Malmqvist

  • Italo R.

    Dear Dr. Rossi,
    According to what has been said, the new 10 watt Ecat-SKLep requires connection to the AC mains and an earth connection to work and consumes absolutely nothing.
    An alternating current generator of any other type cannot be used, such as portable inverter type ones powered by a battery or an alternator.
    The reason for this strange behavior is (for the moment) absolutely incomprehensible, even if I understand that the explanation cannot be given as the technology is absolutely confidential and requires absolute protection until commercialization.
    I still believe the cost of $ 25 / each. is acceptable and that such a device may have an immense market.
    Kind Regards,
    Italo R.

  • david

    Dear Dr. Rossi, please excuse if you have already answered these points. If the E Cat SKLep needs a permanent grid connection to operate, this will automatically preclude its use in electric vehicles. Is this incorrect?.

  • LilyLover

    Dear Dr. Rossi,
    *Congratulations on the MiniSKLEP.*
    1. Am I correct to think that this miniaturization is more difficult/costly to reverse engineer and therefore you feel comfortable in lowering the bar for “entry” for purchase and experimentation?
    2. With this 10W size Ecat, are the investors more happy?
    3. Is it theoretically possible to get 10 MiniSKLEPs connected to grid to get 100W output DC power and then to convert that DC power using an 85% efficient inverter into 85W AC power to power anything resistor or a motor of 60W or less?
    Thank you.

    Dear Andrea Rossi,
    Here are some features of the Mini SKLep:
    “The Minisklep needs to be plugged into a grid connection to operate. The SKLep can produce either AC or DC. Customers will need to specify whether they want DC or AC input, and also DC or AC output.”

    if I order a Mini SKLep input DC / AC output, an inverter is included in the price (for the output)

    1) For the input do I have to buy an AC (220V) / DC (12V) convert or will it be included in the package?

    Regards Maico

  • Red

    Dear Andrea ,
    I also think that 1000’s of potential buyers don’t order because they don’t know what applications the SKLep 100 W. can be used for and whether those applications will work or not.

    Example : 2 SKLep 100W. – Input 220V-AC – Output 220V-AC connected in series is 200W.-220V-AC
    If you connect that source to a boiler with a resistance of 2000W (instead of on the net), what happens then ??
    1: SKLep Provides 200W. ? (warming up is 10x slower)
    2: SKLep does nothing ? and probably yet defect ?
    3: SKLep breaks down ?

    Kind regards
    Red

  • Gerard McEk

    Dear Andrea,
    Congratulations with your new product.
    I have just some questions that bother me. The 10W SKLep has only 2 wires shown on the picture.
    You also told different people that connection to the grid is needed.
    1. Are there 1 or 2 different wires hidden for the grid connection?
    2. Or does the SKLep simply connect in parallel with the load to the ‘grid’ terminals?
    3. Can it be operated from a battery e.g. with proper earthing?
    4. Would you be willing to show a life stream of the 10W driving a 10W lightbulb during a considerabel time that exceeds any available battery capacity, (because I believe that doing this would dramatically increase your pre-order portfolio)?
    Thanks for answering our questions.
    Kind regards Gerard
