Rossi: We can Throttle the E-Cat Plant

Thanks to Allan Kiik for posting this comment:

“Have you noticed this gem:

Hard to ignite and harder to control LENR+ just got a way more useful source, Rossi says he has invented The Throttle for ECatX!”

Here’s the Q&A he is referring to on the Journal of Nuclear Physics:

Q: I am curious, how reactive to a load change are the Ecats: e.g. if the load in the factory fell can the Ecat ramp down the heat quickly and vice versa?

Manuel Cilia:
Yes, we found how to do it.
Warm Regards,

It has seemed to be the case that quickly adjusting the temperature of the E-Cat has not been possible, but Rossi is saying here that that is no longer the case. I would just add to Allan’s comment above, that in this case Rossi is referring to the E-Cat plant which is not the E-Cat X, but it’s very possible they can apply the same principle to the E-Cat X.

    Rossi stated that the catalyst used in his reactor is a group 10 element. This means that the new high temperature unit might use platinum of palladium as the catalyst. Both these metals have a melting temperature in the 1700C range. Therefore the Rossi patent might well cover his newest R&D reactor development.

    Also the EcatX seems now enabled to control at different temperatures:

    I am answering to your comment lost in the spam, eventually arrived by email.
    1- will be the COP of the E-Cat X higher than the Lugano Hot Cat? Yes (F9)
    2- which power will have the serial E-Cat X? That has to be decided, probably we will produce different models (F9)w
    3- will it be possible to regulate it to get different temperatures depending on the necessities? Yes
    Warm Regards,

    If the “Mouse” produces negatively charged muons that excite a group of “Cats” that surround this group, it may be possible to use a negatively charged electric field to redirect the muons away from the group of Cats. This negative repulsive electric field would deaden the muon chain reaction in direct proportion based on the strength of the negative field applied to the mouse.

    • Mats002

      And the “Mouse” should in itself have a COP little over 1, does it fit into this proposal?

      • Axil Axil

        Yes, the job of the mouse is to produce muons and not heat. A rapid response reactor control mechanism must be electromagnetic in nature. The mouse could be surrounded by a wire grid that could be charged negatively in varying degrees controlled by a feedback loop to suppress heat production is the Cats.

      Axil: How high a voltage do you suggest?
      I have an old ionizer that might kick out about 10kV negative.
      Would a negative charge around the glow stick be able to drive the muons back into the reactor?

    Recently Rossi says that the EcatX is a replacement for the hotEcat. But he has also said that the hotEcat is inappropriate for home use and only for industrial use. But they both must be able to achieve 1300 deg C if one replaces the other so the high temp is not the reason the hotEcat is inappropriate for home use. Apparently they both can throttle so that is not an issue. We know the hotEcat takes about an hour to get going which is OK for many industrial uses but this would definitely be an issue for home use unless it is always on. But being always on can be expensive depending on usage.

    So maybe there is a clue there as to what makes the EcatX different. Just conjecture but makes sense.

    Does anyone here have an idea of the method of heat control Rossi may be using ?

    • Axil Axil

      See my post above.

        Many thanks.

    It is obvious that the eCat can be throttled or else it would go out of control. Rossi’s posting provided no additional information as to rate of change, range (low level to high level), etc. But from Rossi’s comments the only thing we can deduce is that an improvement has occurred. The current application, as best we understand, is a long-term thermal energy production at essentially a constant output level. One takes “baby steps” before learning to run.

    • BroKeeper

      Agreed but in my opinion he is taking huge ‘Baby Huey’ steps for this infant

  • Christina

    Great. It’s progress.


  • If Rossi can throttle the X-Cat, with its high heat capabilities it could conceivably be used in a fan-jet engine.
