    Hi @Larry G.

    Great initiative as I really like the inspiration, curiosity and hope that that paper has brought into my life.

    My choice if not already taken is 25 May 2022.

    What ever the actual date that will be quite some milestone.

    Dear Dr. Rossi,

    Jean Pierre’s proposal (april 23) to use the SKLep for a fridge is what I also have in mind.

    But most fridges always switch on and off in cycli. And when they are ‘off’ they always need a minimum of electricity for the light bulb and for the thermostat, which makes that each SKLep is still continuously running at 100W (while dissipating the excess electrons from what I understood which is important for life expectancy). Everytime that such a fridge switches on there is a peak which seem to be even 4-5 times higher than when it is running after a matter of seconds. So, the label on the fridge does not reveal the real peak power (e.g. 200W peak is rather 1000W peak)! This means that we’ll need a lot of SKLeps to run a fridge. Everytime the compressor starts running you can also wonder if this can cause difficulties with the SKLeps because they need several seconds to switch on.

    I think that certain fridges with a digital invertermotor have a huge advantage here because they are always on. This makes that the peak power needed is – from what I read on the internet – about 3-5 times less. But considering that the real peak power of an common fridge is also 4-5 times higher when it kicks in, then it means as a consequence you’ll need probably 12-25 times less SKLep-power to cool your fridge! While there are still other advantages, they make less noise, last longer, have more stable temperatures and consume 25% less power anyway.

    My questions to you are:
    1) can SKLeps run a fridge, knowing that the motor needs inductive load? I’ve found conflicting statements about conductive charge/load in SKLeps.
    2) if an inductive charge is an issue, can many skleps (10 or 100?) stabilise (average) the spikes?

    With kind regards,

    Dear Dr. Rossi,
    as a daily reader of this blog, please let me have some questions:
    1 Have I understood right, that if I make several orders, all ordered units will be delivered on one time, the time belonging to the first order? If not, how is it planned?
    2 What will be the time for distribution for 1 million units?
    2 In this blog you mentioned, that the production for europe will matter on this continent. Is this right?
    3 If yes, can you say, in which country it happens?
    4 You made the offer, that the customer can test the units and take them with him from the factory. If somebody will do this, it is a big effort for you. What will be the circumstances for the test?).
    5 Do you have still the opinion, that the distribution will happen this year?

    Thank you and all the best wishes are to you and your team – Andreas

    Dear Andrea

    As a follow up to some recent questions about the SKLEP output power with different loads. I apologize if some of these questions are repeated I just try to make sure I understood right.

    1. I understand that it is both the output power that does not change with different loads is this correct?

    2. In the case of too large a load the SKLEP switches down.

    3. In the case of too smaller load than a matched one the excess power is not used and so the SKLEP is less sufficient.

    4. A battery could be used to optimally match the overall load and usefully absorbe the excess power.

    Thus sounds similar to me to the power handling me as with other systems such as Solar and I guess many other power sources.

    In the case 3 above but no battery is used I have a few other questions.

    5. Does the extra power go back to the SKLEP?

    6. Does that excess power result in heating of the SKLEP?

    7. Or does the heating of the SKLEP remain irrelevant in this case?

    8. Is this also the case in the case of a short circuit?

    9. Or does the SKLEP also switch Off in the short circuit case?

    Sorry for the long list of questions.

    Thanks and Best Regards

    Hi, Andrea.
    Have you tried to run a simple, small, cheap fridge with sufficient SKLeps with either mains or batteries? This would be useful as a demonstration in my opinion.

    A fridge or freezer is a device that runs for years and all through the year unlike other home appliances. Admittedly, washing machines operate through the year but not quite in the more continuous way that fridges operate. There are longer gaps of non usage with these. Computers are very low power devices by comparison.

    All the best. Jean Pierre

    Dear Fellow Enthusiasts:

    Dr. Rossi is at more than 98K reads for the paper E-Cat SK and long-range particle interactions (researchgate.net) and surely will hit a remarkable 100K readings in the coming weeks/months.

    He has authorized a lottery prize for the person that first guesses the date on which the paper will reach 100K reads, namely a single DC-DC version of the SKLep, only given out if the 1KK pre-order target is reached and units start to ship. I volunteered to moderate the lottery.

    1. Any blogger can post their 100K read guess date.
    2. The first one to choose each date will be assigned that date.
    3. You can only be assigned to one guess date.
    4. If you choose a date and someone beats you to it (can easily happen since this forum is not real time), you can choose a different date. And so on until your date is accepted as the first person for that date.
    5. The blog date and time for the posts will be used as time stamp for the entries.
    6. For tracking purposes, the entries must be a blog posting saying “My 100K #lottery read date guess is MM/DD/YYY”. Notice the # hash mark…I will need that to find the lottery entry posts using key word “#lottery” search.
    7. I will not be eligible for the prize of course 🙁

    Some data:
    You can look at the statistics information on Research Gate for the paper. Also I collected Prof’s tracking of the reads, plus a few of my own, listed here. I give no guarantee as to the accuracy of this data:

    Dear Dr Rossi,
    I have designed and built a 400W desktop space heater where the heater elements consist resistive heaters bought from Amazon. Details are found here at a post today at 14.15
    The heater currently gets power from a 12V DC lab power supply. My object is to replace the lab power supply with four SKLep units each powering one 100W heater element through direct connection of the two element wires to the two SKLep output terminals. May I ask:
    a: Yes, replacing the lab power supply with four SKLep will make the heater work.
    b. If yes, the calculated COP would be: heat output/power in = 100/1 = COP 100
    c. No, it wont work because the wiring is wrong (what is wrong?)
    d. No, it wont work as additional components are needed (what components?)
    e. If it does not work can I return the SKLep I have received and get a refund?
    Thank you very much if you can answer.
    I wish you and your team the best success.

    Dear Dr. Rossi,
    From the latest information written here, it seems that the number of pre-orders is still stable around 800,000, more or less.
    If there are no big news, I’m afraid reaching 1 million pre-orders by the end of the year may be almost impossible.
    If so, what do you plan to do?
    My opinion (and that of many other readers) is that it would be essential to give the market a “shake” by doing another online demonstration.
    We know (because you have repeated it so many times) that you are against repeating a demontration, considering it a waste of time. But to quickly unlock the situation, a new video would be essential.
    I share your concern about reverse engineering, so I believe that a new demonstration could be done in your presence and led by Frank Acland, a person you completely trust.
    The configuration should simply include a 100 watt lamp as load and two DC instruments for measuring voltage, current and power located upstream and downstream of the Ecat respectively.
    The instruments could be of this type (cost around 23 euros / each) and are of class 1
    Very simple, effective and impactful configuration for the whole world. And it would hit 1 million pre-orders and beyond in days.
    My best regards,
    Italo R.

    Dear AR and Wolfgang Vogl
    I am unclear on the use of the word ‘wasted’. It could mean dissipated elsewhere (which could be a problem)m or simply ‘not generated’.

    Dear Dr. Rossi

    You are at more than 98K reads for your paper (9) (PDF) E-Cat SK and long-range particle interactions (researchgate.net) and surely will hit a remarkable 100K readings in the coming days/weeks/months.

    I suggest that we add a bit of levity to this blog and propose a lottery for who is the first to guess the date on which the 100K read happens. The prize would be a single SKLep DC/DC autographed by yourself, delivered once the 1000000 pre-order target is reached and shipments have started.

    I volunteer to keep track of the guesses. Any blogger can post their date guess, the first one to choose each date will be assigned that date. Each blogger can only choose one date. The guesses will be accepted for 7 days. I would give regular updates as to dates chosen and by whom.

    The entries would be a blog posting saying “My 100K lottery read date choice is XXXX”.

    You have the email address for each blogger so you can communicate with the winner.

    I will not be eligible for the prize of course 🙁

    If this sounds good, please confirm you would be willing to provide the single autographed SKLep as a prize, and add/change any “rules” for the lottery that I have suggested. I would then open an official start of the lottery…..fellow bloggers please don’t post any selections until I post that the lottery is “open for business”.

    Dear Dr. Rossi,

    So far you have only specified that the ECat SKLep produces 100 watts of output power at nominal voltage of 12VDC. Assuming the ECat SKLep is connected to a resistive load then a current of 100/12 = 8.33 amperes should flow through the load resistor and the value of the load resistor would be 12/8.33 = 1.44 ohms. Since the load resistance is determined by the customer it is reasonable that the customer would want to know how the output voltage of the ECat SKLep varies with load resistance.

    Question 1
    Have you ever connected the output of one of your preproduction ECat SKLep systems to an adjustable load resistor and measured the voltage across the load resistor over a range of resistance values?

    Question 2
    Are you willing to provide the results of such a test for one unit and 1.2, 1.4, and 1.6-ohm load resistor values?

    Warm Regards,

    Dan Galburt

    Dear Ladies and Gentlemen,

    please can you answer some more questions. Maybe you can put them on your webpage also.

    Lets assume, we combine 10 units to a 1000W “power plant” supplying 240V AC. Therefore we will need an input of about 7W..

    Q1) When the Ecat is producing electrical power, can a part of this power be used as input power?

    Q2) When we use 700W of the output only, what happens to the remaining 300W? Do this cause any trouble or are they only “wasted”?

    Q3) We use 700W. Then we plug in another unit with 500W (why ever). So we exceed the 1000W. What will happen to Ecat now?

    Q4) After a while we decide to buy another 10 pcs. Can those be added to the existing one very easy? Or do you have to change something in the “control electric”?

    Thank you so much in advance for your reply.

    Congratulations to your invention and thank you for going public.

    Best Regards and hello from Austria

    Dear Andrea,
    250 million dollars for 1 million units selled of your e.cat.
    Is not better to sell a quarter of your industrial IP for the same amount of dollars to a partner who is financially stronger than Leonardo corporation? It seems to me a simpler and faster way.
    250 millions dollars are only a small fiche on the table for big financials groups. They can bet easily.
    (think to Elon Musk offering 43 billions (miliardi!) of dollars for Twitter platform control.)
    Maybe your strategy is better, but it needs a longer time to be realized…

    I do not think that new energies will reduce wars, the reasons of the wars on course are more complex and this is not the place to talk about this issue.
    As for the pre-orders status, as I said we are receiving many pre-orders, but we also are cancelling orders after the financial vetting activity upon the big buyers.

    Dear Mr. Rossi,

    my pre-orders for the Ecat SKLep have been placed for what feels like forever.
    According to my last information, the number of pre-orders was over 800 000 units.

    What is the n u m b e r of units that have reached the pre-order to date today?

    Europe is at war again, and people are anxious and waiting for peace.
    Wars are led from interests, the control of the energy is an interest of the powerful ones of this world.
    If it succeeded to give to each humans the rule over its own fire (own energy production), this would be a reason less for warlike arguments.
    Can this succeed against the interests of the powerful?
    The hope carries and drives us humans always further.
    I pray to God that I and my children may still experience this.
    I look forward to an answer and wish them all the best.

    Best regards
    Dieter Zöller

    Mr. Rossi,
    Does the SKLep require ambient air (outside the SKLep housing) for its operation ?

  • Pavel

    Mr. Rossi,
    If an existing customer makes another new SKLep order, but with the condition that they pay for and collect it after the previous order has been delivered and successfully operated, will you accept this new order (will You add the number of SKLeps of this new order to the number of existing pre-orders) ?
