Rossi on Increasing Power Using Hot Cat Clusters

Andrea Rossi has mentioned a little more about the latest Hot Cat configuration, which seems to have been built following the pattern in the 1 MW plant in which ‘synergy’ has been reached between reactors, thus increasing the overall COP of the plant.

He wrote in one comment:

The Hot Cat modules will too be assembled in clusters to increase the power.

Just to make sure I understood what he meant with this comment, I asked him:

When you say you arrange the Hot Cats in clusters to increase power, are you able to use one Hot Cat reactor to drive another, thus reducing overall energy consumption from the grid?

Rossi responded, “Yes”.

It’s still not clear how these clusters work, and I doubt Rossi will give too much detail at this point, but it seems that Rossi has figured out a way to get reactors to work together somehow — in what he calls a ‘synergistic’ way.

To me, the ability to combine reactors in a cluster seems to be quite a breakthrough for the E-Cat. We don’t know how many reactors comprise a cluster, but the idea of having a chain of reactors feeding one another has been discussed for a long time as a way to reach a very high COP.

If you can use one reactor that is already running at a modest COP, perhaps even running in self sustain mode, to stimulate a reaction in a separate E-Cat reactor — and perhaps there would be more than one reactor involved — the cumulative power needed to get multiple reactors going could be quite small.

Hot Cats run at temperatures high enough to create the high temperature steam needed for efficient electricity, so this apparent clustering breakthrough could be very important for Rossi’s goal of creating electricity competitively.

    Science has discovered Nature demonstrates the most efficient designs. As in the fission nuclear reactor
    control rod configuration of choice is the honeycomb. The staggered control rods evenly disperse
    radiation to it surrounding static core.

    The same configuration may be worth considering for an E-Cat plant design with similar staggered controlling mice evenly dispersing heat radiation to its surrounding six cats. If placed correctly each cat would be bordering three mice and each mouse surrounded by six cats with fluid/gas ports at the nodes for heat exchange. With this honeycomb configuration modules could be stacked contiguously. I believe this may be what Rossi is conveying when speaking of E-Cats synergy in cluster/modular form.

    Eventually there may be clusters of tiny fuel globules mounted on moveable mounts. The proximity of the globules would be variable. To speed the reaction, the globules could be brought together–to slow the reaction spacing could be greater.

      There is evidence from the Lagano demo that the fuel is mobile. Any plan to fix the position of the fuel will not work because of the mobility of the fuel. Even in the MFMP tests, lithium coats the sides of the rector wall.

      • William D. Fleming

        OK, since the fuel is mobile there maybe could be a cluster of small reactors attached to a device which would vary the reactor spacing automatically depending on temperature. Just an idea.

      Statistically all you need to do is have multiple units to average the temperature among them. There is no need to be elaborate moving them. The more nodes the more are in the mean assuming they maintain stability over 50%.

      Ten nodes at 60 % stability means six are in the optimal production zone at any time and four not, on average. The six maintain the temperature of the four and you have a total free ride. There is still the potential for infrequent statistical variation. In an extreme event only one could be optimal and nine could have below optimal output and they would all sustain until the moment passes and some come back into statistical balance. In the furthest extreme they could all be in a moment of simultaneous suboptimal output and the heaters kick in to ride out the moment of the statistical aberration.

      • William D. Fleming

        I see what you are saying, that statistically the cluster could be self-sustaining without motion because the cells would start to fade at random times, so with the right spacing and the right number of cells, there’d be enough active cells to keep the reaction going.

        But if the entire cluster started to get too hot, being able to separate the cells might be a way to prevent a meltdown.

        It’s so entertaining to espouse ideas and it doesn’t cost a dime. 🙂

      Pietro, do I understand correctly that this document identifies the name and location of the customer for the 1MW plant?

      • Wishful Thinking Energy

        Actually, it sounds like the plant is in Miami. The address identified in Boca Raton is to an office building, and JM Products Inc. doesn’t seem to have any internet presence.

      this is a great find. Someone li Nevanlinna on Cobraf could dig out much more info about it.

    How the cat and mouse could work:
    It could be that the cat part of the cat and mouse is a setup where the cat runs at a higher temperature than the mouse and provide heat to many mice (the mice providing the main source of energy output) in a controlled fashion via some working fluid (could be water / steam). That way all the mice can be given heat if they need it or be cooled if needed by mixing hot fluid from the cat with colder fluid. This way each mouse can be provided the temperature tailored to their particular needs.

    Additionally, the plant as a whole can have variable output power, the mice can be cooled down to reduce power or warmed up to increase power and in the meantime the cats can remain hot, ready to get the mice going to meet the to meet the varying manufacturing requirements. Hot fluid from the cats (water / steam) can be stored in a small vessel (boiler) ready for instant use.

    A similar setup could be made with Hot-Cats using air as the working fluid.

    There seems to be increasing convergence between mouse/cat LT reactors and ‘Hot Cat’ types, which may indicate that the two ‘types’ are just variations on a theme, differing perhaps in size and construction materials, but essentially similar in other respects apart from operating temperature.

    However, if Rossi is sitting in a control cabin all day nursing his LT pilot reactor – then who is doing this development work on HT eCats, and where is this taking place? About a month ago he said on JONP, “R&D on the Hot Cat is going on here where I am working with the 1 MW E-Cat”. His latest comment seems to be further evidence that hot cat development is taking place on the ‘customer’s’ premises, alongside the testing of the pilot plant.

    It seems unlikely if this is the case that the ‘customer’ is an independent entity, but rather some facility owned by either IH or a sponsor we haven’t heard about yet. More surprises yet to come I think.

  • The “clustering” or the”mouse to cat” perhaps is what the “Rossi effect” is, more than a secret sauce for the kitty.

    I would assume that he is using one or two modules as a pre-heater so that less electrical energy is used to get the other reactors up to heat and to be sustained.
