Here’s a Q&A on the subject from the Journal of Nuclear Physics today:

Dr Rossi:
1- do you already have a gas turbine operating?
2- if yes, which dimensions vs power?
Regards,
Chuck Davis

Chuck Davis:
1- yes
2- the power density is the highest I ever reached. Premature to give numbers.
Warm Regards,
A.R.
Rossi has said previously that the ratio in size of the 1 kW QX to the 100 kW SK is 1:10 which, if true, would make the power density of the SK 10 times that of the QX. There will of course be losses when combining the SK with a gas turbine, but even if the turbine was only 20 per cent efficient, it would be twice the power density of the QX.
Steven Karels asked Rossi about how they are dealing with the very high temperatures the E-Cat SK is reportedly producing:

Dear Andrea Rossi,
It is difficult for me to envision of 100kW eCat SK reactor that can sustain the temperatures you report without damaging or melting the containment structure. Is the containment structure transparent?

Steven N.Karels:
The gas turbine configuration resolves the problem. We are working on this issue for other configurations.
Warm Regards,
A.R.
Still, Rossi has said that the SK is not ready for production, and apparently they will have to make a decision at some point whether it will be launched as an initial product. When I asked him whether the SK and QX both need to be ready before they can do a product launch he replied, “No. If the SK will not be ready, we will start with the QX anyway.”OK, Rossi is dealing with his SK reactor's "excessive energy" density issues, same as Mills did. Rossi's "short Coke bottle" sized SK reactor is tending to spot overcome every cooling use load scenario he has come up with, save two.
The very first "big enough good enough" variable adjustable cooling load is heating up a VERY LARGE flow of water as in a free flowing large commercial hot water building heating system.
The second use is in a liquid CO
2 based turbine mated to a generator electricity producing set up that has the ability to constantly dump the excess electricity generated off into the electrical power grid. Rossi uses a flow of cooling water to condense his pressurized CO
2 back into liquid form, so he still gets his large volume flow of output hot water for building heating as a free secondary by product.
Rossi apparently likes this one because he can get a tremendous amount of very effective spot cooling off the boiling liquid CO
2 getting large amounts of evaporation point cooling at -78o C instantly [u]when he needs it ASAP as a variable control element for heat spikes[/u] and he gets even more extra electricity being generated from a heat spike now instead of just having to just pay a lot more money for more power to run liquid water cooling pumps that much faster as is currently used in his simple "building heating" hot water uses.
Because he has a bunch of good "variable" liquid CO2 cooling available, Rossi is now trying for higher energy densities that are beyond anything that he has attempted before. We know that the output of his system has to be in balance against the cooling load and the cooling reserve amount needs to be "large" so having good cooling instantly available means he can crank his SK up some more, safely.
These are the two items that will likely be able to be shown at the 2018 New Year's demos as the COP figures are
very good and the equipment seems stable enough when run at steady states.
Making electrical power and heating hot water, both are very good safe initial uses for Rossi SK tech .....The COP calculations for an electrical generation system will be interesting, since he has the power output from the electric generator which easily exceeds his energy use rate for his control boxes AND he has the water heating capability from the liquid CO
2 condenser to make up his building heating hot water (or other forms of water based heating uses).
Could he justify saying his COP is very very very high once the whole system is cranked up and working ???? Likely he could.
Easy to get AC cooling off the same system, just evaporate some of the liquid CO
2 in a cooling coil or jet a flow of high pressure CO
2 gas through a venturi to provide building type AC water spot chilling. I suspect this use would require a condenser or water chiller type system outside the building to dump the remaining excess system heat outside the building, but that sort of action is well understood by HVAC companies already.
Fancy RV AC/Heat systems already do these sorts of things in relatively small units, using propane gas tanks to provide the primary heat source. Propane heat can run RV refrigerators too, so a small Rossi heat system should work in that application as well.
Remember how the QX went from 20 watts to 60 watts to 80 watts to 100 watts in output per reactor once his new team had tuned on it some.
I bet we will see eventually something close to the same 5x level of output progression in the SK unit as well given sufficient rapidly adjustable cooling and the ability to have a large cooling reserve to handle heat spikes ......
Potentially Mebbe Half a Megawatt of heat output per small coke sized reactor which right now as we speak can reach plasma temperatures of up to 20,000o C ????? In return, I am waiting for the smaller QX reactor to gain some more "you got good cooling now, turn it up some more" spec ability from the work Rossi and crew are doing on the SK upper end --- they are now learning how to deal effectively with the higher output levels, balancing larger outputs against good cooling and ample cooling reserves.
===================================================
IT ALWAYS SEEMS TO GET BETTER AND BETTER ....... Rossi now admits that the real world rating on the small and large reactors depends on the LOAD TYPE (or cooling ability) of that particular set up. Given something that can cool a great amount re-actively (adjustably) then the overall "kilowatts output" of that particular rig can go up accordingly.
Next, Rossi is in "automated assembly" (low volume type production) on QX samples that are getting sent out to selected customers on a "trial fit, run, then return ASAP" basis. The customer just pays for the heat as they have no ownership of the sample units whatsoever.
Customers really need a trial unit so they can really see if their idea is worth sinking lots of their capital dollars into developing.Next, Rossi will have his first 4 internal "permanent installations" functional by November.
He will be in low level automated reactor production for customer units at that time.
December is set up time for public display review (the big coming out party) in January-February.
First hints have now been dropped on a still MUCH LARGER reactor that is now under development. This unit would be a public utility sized single reactor and would require MASSIVE amounts of very reactive cooling to be practicable at all as it is similar in output to a Mills unit.
Exposure of biologically tainted water to extreme amount of Ultra High Frequency ultra violet light (EUV) can clean up and destroy all living biological contaminants and can break down most all forms of organic poisons that those toxic life forms produce. Plus the water gets up over 140 degrees in the process, which is medically recognized as "sterilized by boiling" type temperatures. Treat it with some clorine and other water purification chemicals and you get potable drinking water off a jeep towable (readily portable) purification plant.
Rossi's reactor outputs LOTS AND LOTS AND LOTS of EUV light so very very strongly it can break down water molecules into free hydrogen and somewhat temporary HO ions which will recombine later (unless they are separated immediately and the mono atomic hydrogen gas utilized in some fashion). Fuel cells can run off this mono atomic hydrogen gas just dandy.
So, a very powerful Rossi reactor can act as a self-powered container sized water purification plant, in other words, getting its pump electrical power from a fuel cell electrical generator.
