COP eCat between 125 and 143….(?)

Here’s a question sent by John Schut:

“Did I understood correctly that Anrea Rossi has indirectly stated that the COP of the eCat is between 125 and 143? This because he stated that the eCat uses 7 à 8 KWatt/hour while producing 1 MWatt/hour.”

John’s question is based on a statement made by Andrea Rossi yesterday on the Journal of Nuclear Physics when asked by a reader what the input power was when the 1 MW plant was in self-sustain mode, including consumption of the air conditioner and ‘entertaining gadgets.’

Rossi replied:

Rethinking, what you ask for can be answered: the comsume of current when the 1MW E-Cat is in ssm, producing 1 MWh/h is betwen 7 and 8 kWh/h. The air conditioner is not included, because powered from a source independent from the E-Cat, as well as the light. Entertaining gadgets are Physics books, they do not consume current. The current is consumed by the control panels, triacs, transformers, safety systems.
Warm Regards,

Someone responded by asking Rossi if this meant that the COP would be between 125 and 142 (as John asked)

Rossi responded:

“You must make a distinction between the ssm and the non ssm cycles. We will give the data related to the performance of the 1 MW E-Cat after the end of the tests on course.
For example now, at 7.54 a.m. of Sunday August 2, She is not in ssm; all stable, all good, no problems by now, and the control system has put Her in not ssm mode.”

So at this point it really is not possible to know the average COP of the plant, because we don’t know the duration of the SSM periods in comparison to the non-SSM periods. We don’t have any data to go by, except the spot-checking we get when Rossi is asked on the JONP what the plant is doing at a particular moment. I have tried to compile those responses on this thread:

From the responses compiled, Rossi says that out of 14 entries, 10 times he mentions that the plant is in SSM, 4 times the plant is “stable”. A reading once in a while is random, however, and I’m not sure we can determine a statistically significant pattern from these data points.

    Actually, would not 80% ssm at a COP cop of say 8 give you

    Think of 10 units of energy.

    Input: 1 1 0 0 0 0 0 0 0 0 = 2 units of energy supplied
    1 2 3 4 5 6 7 8 9 10
    Output:8 8 8 8 8 8 8 8 8 8 = 80 units out

    So your COP will be 40.

    At 90% ssm (9 units), then you get 80/1 = 80

    If the static COP is only 3, then

    Input: 1 1 0 0 0 0 0 0 0 0 = 2 units in
    1 2 3 4 5 6 7 8 9 10
    Output:3 3 3 3 3 3 3 3 3 3 = 30 units out

    30/2 then cop = 15

    Of course the above assumes a “constant” output when in
    SSM, and I suspect it more of a “downward” curve that the controller “kicks” on
    the power before the curve drops below the tempature in which the LENR effect stops.

    So perhaps another analogy is those guys that spin plates – you run around and give each plate a spin like this (think of EACH plate as a LENR reactor core!). Just needs a “spin” once in awhile to keep going!

      I don’t really understand your remark.
      I get the impression that you mixup COP and Output(?).
      You speak of 90% ssm (9 units), but the input is still 8×0 (which must be 9×0).
      Furthermore you set the output differently, while it should be always the same (1 mW/h because that’s the output of the E-Cat).The COP is nothing more or less then the outputed 1 mW/h divided by the totally inputted power.

      • Albert D. Kallal

        thanks – that is a type-o – yes I mean 9 units for the 2nd example of same cop, but THEN I go back to original 8 units with a different COP – I edited the post to make this more clear.

  • Albert D. Kallal

    But due to so many small reactors, they not all going to be powered at the same time – so in a merry go round approach, you have the units staggered.

    In other words you don’t put power to all 100 units – you put power to a few
    and once they SSM, you use that power for other units. Once you get them all staggered, then you only powering 20% of the units at a given time (assuming 80% SAM). So you would never “sync” them all at the same time to require power.

    In fact this issue MUCH shows how using many smaller
    devices is better than one big unit that would require huge amounts of power
    when “on”. And this also applies to startup – you only need power to start a few, and once they SSM, you use that power to startup other units.

    Rossi has stated the max input is about 250,000 watts,
    but he also stated above that the power consummation was only about 8000 watts
    to get that 1 million watts output. This is only possible by staggering a bunch
    of small units like a conductor managing a musical symphony.

    Dear Andrea,

    Is it possible for the 1 MW plant to be in ‘partial’ SSM — meaning that some reactors are in SSM, while other are in non-SSM?

    Or is it the case that in SSM, the whole plant is self-sustaining?

    Many thanks,

    Frank Acland

    Frank Aclkand:
    Both modes are possible.
    Warm Regards,

  • John Schut

    I think the COP calculation from Seppo/artefact is the correct one. In the graph below the input (in kW/h), the ‘excess heat’ (in kW/h) and the COP are given. In my earlier graph it looked like only very high COP’s made a difference, but this graph makes better clear that the advantage of more excess heat is linearly profitable.

  • Jouni Tuomela

    Just thinking of future innovations;
    If the control systems puts the whole plant in SSM, seems to me disturbing, when from the amount of individually controllable pumps one can imagine that each reactor has it’s own pump to regulate the cooling.
    Then each reactor should have it’s own contoller also, and then it is unlikely to me that all reactors together would go to SSM.
    Hmm. From somewhere I waguely remember that inside a “group” the menstrual cycle of female seems to syncronace over time, also some pendulum systems do it!

  • Buck

    Seppo . . . I stand corrected. Thank you. You are right.

    I’ll be back later today to use the COP figures from the Lugano report . . . a tested conducted under full power at all times . . . no SSM.

  • Christopher Calder

    Well, Rossi certainly seems to be the leader today. As it appears the Solar Hydrogen Trends device is just a battery, not an energy source at all, their COP has to be less than 1. Defkalion claimed a COP far above 20, but where is their product now? They have been silent so long it appears they hit a roadblock or were bought up by a secretive larger corporation. Brillouin has interesting ideas, but has never proven a high COP. The simplified hot fusion companies are years away from having a usable product, but long term they could be competition.

  • John Schut

    The difference between the method of calculating the COP between Buck (blue line) and Seppo/artefact (red line) is quite enormous. I am not sure what the right approach is. Can someone maybe shine a light on these two options and explain the correct approach?

  • artefact

    if the COP is between 20 and 80 there should be a very high ssm ratio. ( )

    between 87/13 (COP 19,88) and 99/1 (COP 88,86)

  • ecatworld

    Yes, for this test it is. I think the plan is that you won’t need to have that round-the-clock monitoring in working plants.

    • Gerald

      In the future 24 hour monitoring won’t probably be necessarily. My guess is that the first customers are big heat users (or cooling like a datacenter) and they mostly have already 24×7 thechnical support on side. So the technical employes only need to be educated how the plant works and affects their normal process. Probably remote support will be used in case of unexpected events.

      I’m thinking jobs now. Educated people, support, repair etc etc. It will take a lot of (old) new people who know how energy(heat) transfer works. By my experience the people now working that area are very old fashion using nature laws as we know it now. So in first they will be very septic but once they know and trust there’s a box container size who gives controllable heat at a profitable cost they will go mental upgrading there old systems. No doubt.

    It is good of Mr. Rossi to continue to give out these bits of information, that all put together tell us a good deal about the situation.
    It is defiantly worthwhile to keep watching as any day more disclosures could be coming, plus the many replication attempts may at anytime show something new or spectacular.
    Never in the field of science was so much owed by so many to so few

  • Buck

    For fun, I assumed that in Sustain Mode the COP is 3 and in SSM mode the COP is 125, the more conservative value presented above. The first two columns below represent the proportion of time divided between the two modes. The reason I started at 20%-80% is that this was the proportion used by Rossi on the recently redesigned Hot-Cat.

    The last column hopefully is plain to understand.

    To me, the table below easily puts the projected COP into the rumored COP of 20-80 some months back.

    3 125 Projected COP

    20% 80% 100.60
    25% 75% 94.50
    30% 70% 88.40
    35% 65% 82.30
    40% 60% 76.20
    45% 55% 70.10
    50% 50% 64.00

      as reference Rossis post:

      Gerry Carillon:
      We reached 1380°C and resisted for about 10 hours at that temperature, of which 8 hours in ssm.
      Warm Regards,

      • Gerrit

        Based on current infos we can conclude that a COP of 20 seems very conservative. The range is more likely COP 60-100.

        • artefact

          I thing Seppo below has it correct.

    • georgehants

      Buck, at a cop of your lowest, say 64 what would this mean for the % of present industrial power that could be replaced by e-cats at a worthwhile cost advantage?

      • Buck


        a COP of 64 would displace about 98.44% of the electricity historically purchased from the grid.

        Put differently, with a COP of 64, you would only need to buy $1.56 of grid power to get $100 worth of heat.

        Please note, this provides a HUGE margin to Rossi’s/IH’s business even if they set their E-Cat pricing to save the customer 50% off the customer’s traditional monthly industrial power bill. It would seem to be like printing money.

        Now, what plant manager wouldn’t want a 50% reduction in energy costs in COGS? And there is essentially no carbon footprint or pollution.

        • georgehants

          Buck that sounds stunning, we have just asked Mr. Rossi the below question if it gets through moderation and he answers.
          I wonder if others on page agree with your helpful estimates?
          Dear Mr. Rossi if you are allowed to answer, could you say, allowing for
          your fuel mixture to very complicated, when mass produced will it’s
          manufacturing cost be expensive compared to say just plain Nickle?
          Best Wishes

            What I can say is that the price of the charge is irrelevant, due to the tiny amount of it respect the energy produced.
