It would be interesting to see and understand your reasoning for this assumption. Do you really believe that Rossi found a a nice and smart way to handle in a power station or whatever kind of battery thousands of his tiny magic 20W sticks (30mm long and 1mm in diameter, IIRC), each of them running at temperature of 2600°C (!) and creating excess power (light, electricity, heat, probably, thrust and Axil only knows whatever kind of other unknown alien particles) lighting up the room with an amazingly blue aura?
I would not risk to run into trouble with such incredible new stuff, but would make millions and billions with my good old ECat. There are so many satisfied customers already.... BTW - will all of them apply for an upgrade to Quack technology? Guess, yes, since Rossi himself dropped his old one for the new toy...and will probably no longer support his old cats...
So , next epiphany of ECW's LENR messiah will happen by end of October 2017 - a "demo" to whom? Maybe E48? Looking forward to read what'll happen...
I don't know what the features of QuarkX are, but I think the demo will show us an extraordinary and very different object from the reactors that other members of the IH portfolio claim to have. But if you had a revolutionary object in your hands, would you really dedicate time and resources to something else? Rossi tried to make improvements to his old type of reactors and succeeded in his intent, inventing something he said was much superior. I do not see why he should be fond of what probably is for him a technology already outdated.
