QX Concepts - A less critical Rossi thread.

  • Maximum capacity for a 4 bedroom house with hot 180F water heating at 6 gallons per minute at outside ambulant temp of 0 F.

    Hot water heaters are 34,000 btu/hour. A large home furnace in the U.S. is 100,000 btu/hour. 134,000 btu/h = 39 kW, not 100 kW.

  • Thanks Jed, that is my mistake, I should have said 100,000 BTUs.

    Jed, I had just posted that my house used ~15 kW. Why on earth would I suggest 1 kW would be adequate?

    100,000 BYU/hr is 29 kW.

    Anyway, the QX is on hold and it is the SK production line that is being built.

    An SK 20kW is overkill for a water heater so there may be a market for the QX.

  • Although the QX doesn't operate in a vacuum, I wonder if this effect is at play with the platinum coating of the nickel manganese electrode.


    The behaviour of vacuum arc discharges at hydrogen impregnated electrodes

    Abstract:This paper is concerned with experimental studies of the behaviour of vacuum arcs at hydrogen impregnated electrodes. The arc discharges were analysed by high-speed photography, registration of arc voltage and current and measurements of the erosion upon dependence of the level of impregnation for a wide range of arc currents. The results show that impregnation of electrodes with hydrogen reduces the erosion rate, causes smaller crater dimensions, changes the macroparticle size and decreases the current per spot. For a given current, the arc voltage depends on the degree of impregnation with hydrogen. The voltage of low current arcs decreases with increasing impregnation. Furthermore, the arc discharge burns more stably on impregnated electrodes. The total erosion rate decreases significantly due to the reduction of the droplet fraction. The spot movement is mainly faster than on nonimpregnated electrodes.

  • 20kW would be ok for a water heater. Many electric showers here in the UK are 8-12kW but the flow rate isnt great. 20kW would be pretty decent. Enough for body jets etc.

    A typical water heater in the US has ~5 kW and a 80 gallon tank. I changed to gas as it is cheaper.

    So 20 kW would be overkill & more expensive due to the heat exchanger required.

    An Sk might work for a tankless on-demand system. I haven't done the sums.

    Jf to days fuel was not a "market price" stock market driven lets get rich modesty would you still be interested in the percentage gain?

  • PforD.

    You have NO hint, let alone proof that a factory is not being built.

    Please follow the thread guidelines and refrain from posting your unsupported negative opinions. Rossi ws offered financial help to build a factory in PA earlier this year and turned it down saying he was already committed.

    Dear Dr Andrea Rossi,

    Will you make other validation tests on the Ecats?

    All the best,

    No, because now we are at the industrialization phase. The “validation” is made by the Customers. This said, our R&D activity obviously will continue, as it happens for any industrial product, as well as we will continue our strong effort in the theoretical field related to our technology.

    Warm Regards,


  • I think most sufficiently thin light materials will be "transparent enough" to X-rays, unless we're dealing with very low energy X-rays, conceivably on the order of 1-2 keV or so, which would need truly special materials to be technically useful as an optically transparent container (unlikely) or as a window component.

  • Rossi said today:

    "The aim of the January 31st presentation is not to get a validation. We are presenting a service that is based on an industrial production, not on a prototype that needs to be validated. The goal of the presentation is commercial, not scientific and has to be object of clear distinction from a work of R&D,

    The assembly will start at the beginning of the year 2019."

    Tehre will be inevitably be some debugging required and I hope he will test some early units for a reasonable time before putting them to work.

  • Adrian, forgive my ignorance (because I have missed much of the latest eCat banter) but what does SK stand for? I recall Rossi evaluating his Quark X based on what he called a Sigma rating, and if I recall after some time it reached a sigma 5 (although I was not sure what that meant, but presumably some kind of measure of reliability). Anyways it seems the SK came very soon after, and in a moment of musement I imagined it stood for Sigma Killer. That is, it was inherently stable or reliable. But this is just my imagination at work.

    Off on a tangent now; back in the day when I was following theses things, when Rossi was working at Dorval overseeing the plant operations, that's when he came up with the Quark X. It was announced right around the time when his relationship with IH was going sour, or south. I always wondered if Rossi started working on his new project (the Quark X) because 1) he got wind that Industrial Heat did not have his interests at heart with his then existing IP, so he decided to launch into something new with the Quark X, or 2) Rossi started work on his Quark X and was not sharing that IP with Industrial Heat, which then ticked off IH, or 3) the same timeframe for the invention of the Quark X and the souring of relationship between Rossi and IH was just a coincidence. Thanks for any insight you might share.

  • Do you have any thoughts on QX replication?

    I don't think enough is known to attempt to replicate it. In any case, the SK series seem to be the reactors going into production, and they would be the ones to replicate if the information is made available. As Rossi says he will not release it this is unlikely to happen,

    The main point of replication is to prove if something works. We will know that soon enough by whether Rossi keeps his old customers and continues to have new customers.

  • I want to get this thread back on topic.

    First, if you are going to participate on this thread, please try to assume that we have at least enough basic information to get us started on a replication.

    Secondly, I'm curious if anyone has any suggestions about where to get components, how to coat the nickel electrodes with platinum, how to produce a vacuum in the reactor, how to produce the field emitter tip, how to build a power supply, etc. We need to start at least putting together ideas on how someone could move forward on a replication.

  • That would depend on the team. We don't know if anyone on the team that builds a QX will be skilled in electroplating or not. Also, we should probably look at the platinum layer produced by electroplating and see if it would hold up to a plasma well. There may be other methods of depositing a platinum layer that are better.

    I really think it is up to the LENR community to make sure the QX sees the light of day. I don't expect Rossi will ever attract the investment he requires while maintaining such strict secrecy and refusing to share know how with partners.

    As I've said before, I think the good news is that we have a basic understanding of the QX and the principles that make it work. Primarily, interested parties need to go back to the work of Paulo and Alexandra Correa and Chernetsky and learn about the abnormal glow discharge regime (the region between a standard glow discharge and an arc discharge).

  • Here is a question for everyone.

    What is a reactor tube material that is transparent to optical light and x-rays?

    I did check with a boron nitride supplier (in Germany), if the term "transparent boron nitride" rings a bell. He has never heard about such a boron nitride type. Any proposal?
