Dear Andrea Rossi,

You posted that the equivalent temperature of 1 eV is 12,500 K. Please check and see if my Physics is correct?

1 eV = 1.602… x 10**-19 J — (one electron charge moving through a potential of 1 Volt)

Boltzmann’s constant is 1.38065… x 10**-23 J / K

So the equivalent temperature of 1 eV is:

1.602 … x 1-**-19 J / 1.38065… x 10+++-23 J/K = 11,604.5… K.

So should not the equivalent temperature of 1eV be 11,604.5K?

Note: this is the equivalent temperature, not the actual operating temperature.

Dear Dr Andrea Rossi,
I understand that you produce very high energy in very small space: did you find the right heat exchanger in the market, or had you to design a new one?

• Andrea Rossi

Raffaele Bongo:
Thank you for your kind attention to our work.
About how the heat is exchanged, it is confidential.
Warm Regards,

Hello A. Rossi

You had to overcome enormous difficulties to move from an operating temperature of 2700 K to 12700 K. I suppose that these very difficult changes are aimed at improving the performance of the reactor. I have a hard time imagining that one can reach such temperature without confinement.
Can you tell us a few words about these new performances of the reactor?

All my support for your entire team
Best regards

Raffaele

Theoretically the plasma is a perfect black body, but since a perfect black body is not supposed to exist, we calculate epsilon= 0.9

Fighter:
Correct.

Steven N. Karels:
1- In my comment I made a typo with a consequent error, obviously K= C + 273, not the other way. Corrected.
2- 1 eV= 12 500 C degrees, then 1 eV = 12 500 + 273 = 12 773 K
Warm Regards,
A.R.

• Fighter

So, if I have correctly understood, the hot fusion is more “impossible” than the LENR. At least from your point of view. Correct?

• Daniel

Dear Andrea,
Watching the video of the full demo you made in Stockholm on November 24th with the Ecat QX, I saw that when you calculate the temperature of the plasma by the Wien equation and eventually you calculate the energy by the Boltzmann equation you consider the plasma to be a black body and consequently you apply the value 1 to the epsilon (emissivity).
Is that correct?

• Ernest

Dr Rossi:
Still on schedule to introduce in the market the Ecat QX within the end of the year?

• Andrea Rossi

Maja Berken:
Yes, I do.
Warm Regards,

Dear Andrea,
Thank you for your answer to the magnificent comment of Beata Chowen.
Don’t you think Prof Marica Branchesi should be more shown and interviewed by the media, to make her inspiring figure be more widespread?
Cheers,
Maja

• Andrea Rossi

Beata Chowen:
I am glad to apprehend this, not only for the importance of the scientific achievement, but also for the inspiring model that Prof Marica Branchesi offers to the future women.

• Prof

Dear Dr Andrea Rossi:
What impresses of the video of the Stockholm demo of the Ecat QX is the number of so high level Professors that have observed the set up closely during all the test, approaching the Ecat and observing all the particulars of the Ecat and of the measurements.

• Andrea Rossi

About the comment of Jean, the link to article of Per Kristian Bjorkeng on the Aftenposten can be found on http://www.ecat.com selecting “NEWS”.

1 eV can be converted, obviously, either in Celsius degrees or in Kelvin. 1 eV= 12 500 Celsius degrees and 1 eV= 12 773 K, albeit when you measure a T in eV the difference between the two scales is not as relevant as it normally is.
Warm Regards,
A.R.

• Jean

@Abe Vincent:
I totally agree with you. Being a nuclear engineer, I too was a sceptic, but the video of the demonstration of the Ecat QX made at the IVA of Stockholm has been very convincing.
Impossible to ignore the precision of the measurement of the flowrate, the diagram of the oscolloscope with the measurement of voltage and the unipolarity of the current across the resistance of 1 Ohm, the measurements of the dummies and of the calorimetry made by neutral engineers. The team of Rossi has made a masterpiece, giving evidence of the enormous potential of this new source of energy, as written by Per Kristian Bjorkeng on the Aftenposten, the major newspaper of Norway.

Dear Andrea:
When the temperarture is measured in eV the conversion is in Celsius degrees or in Kelvin?

• Andrea Rossi

Abe Vincent:
Thank you: I appreciate your attention to our work.

Chuck Davis:
Thank you for the link. It is another thermoelectric device, working with the Seebeck Effect. Due to the experimental status it is too soon to know if it has enough efficiency. I have a big experience in the field, because I worked very much in it also for the DOE in the nineties and made a patent in the USA with Leonardo Technology Incorporated. But what I experienced is that when you make by your hands a prototype ( very expensive ) you get a good efficiency, but you have to spend hours and hours with the directional fusion, necessary to achieve a geometry that puts in line the atoms; when you, for necessary economical reasons, pass to a bulk production and you have to speed up the directional fusion of all the components of the alloy, whatever it is, the efficiency drops dramatically.
We’ll see: if they have resolved this problem, that I have not been able to resolve, this is a good fiance’ for the Ecat, for obvious reasons.
Warm Regards,
A.R.

Dr Andrea Rossi,
I bought by Amazon the book of Vessela Nikolova ‘Ecat the new fire’.
Do you confirm that what is written in that book is true?
All the best,
Sandro

• Abe Vincent

​Dear Mr Rossi, Thank you for the convincing demonstration in Stockholm. I wasn’t convinced before the demo, but after seeing the 6min video I was definitely convinced. The measurements of the output power of the reactor was particularly convincing.

WaltC:
1- no
2- the Carnot cycle components are well known and on the traditional market
3- no, we will make steam, then our Customers will use the steam to do what they want, as, for example, electricity my means of the Carnot cycle
4- you are not wrong
Warm Regards,
A.R.

• WaltC

Dear Andrea,
Thanks for the clarification– so in the case of “Carnot cycle is made by steam that makes a turbine turn a magnet inside a copper coil”, let me rephrase my question:

1) Do you plan to build that device yourself?
2) Or, have you found a supplier for such a device, either for Research purposes or for Commercial operation?
3) Or if not, are you currently looking for such a device?

And– I apologize for what must be an odd sounding question:

4) Am I wrong to think of this device as an external heat source (steam) that powers an Engine (turbine) that then drives a generator?

thanks again,
WaltC

Dummy Physicist:
Hot fusion temperature in a plant like the one ENEA has invested in is above 12 keV ( more than 150 000 000 – say onehundredfiftymillions- of Celsius degrees ).
To maintain stable magnetic fields at this temperature is more difficult than allow an elephant pass through a needle eye. Non maintaining a stable magnetic field in a plant like that means not just melt, but vaporize any kind of material or alloy exposed to such a radiation in matter of fractions of second, making happy a lot of people around. But the good news for the “financers”, funded by the taxpayer, are that all this stuff justifies any kind of expense without bids and without control, because nobody understands what they are buying and why… not that it counts too much, though.

I googled “Ecat QX video of the November 24th demo in Stockholm”
Fantastic, well done, it seems to be there during the whole convincing presentation of the Ecat QX
Thank you for this magnificence

@Aninumous of the comment 2018/04/19 at 7.52 PM: you are an imbecile. Even if Andrea Rossi will delay, it will be anyway a masterpiece, made by his own money. Compare to the “work” of the hot fusion, that is stealing money of the taxpayer by the billions since more than 50 years and the sole thing they produced is the request of more money, without any serious accounting control, like what happened few days ago with ENEA, that is wasting 50 millions to make the usual nothing they make.
You know why these smartasses can continue this clownerie? Because of imbeciles like you, that look at the straws not seeing the pillars.
Rita

• Dummy Physicist

Dr Andrea Rossi,
How can the Ecat QX sustain a temperature of 1 eV? Is it not the same T of a hot fusion ?
Thank you if you can answer,
Dummy Physicist

• WaltC

Dear Andrea,
You mention using the Carnot cycle to produce electricity– presumably based on an engine that can operate from an external heat source– have you found a supplier for such a device, either for Research purposes or for Commercial operation?
If not, are you currently looking?

thanks,
WaltC

I can’t wait the day you will find some excuse to communicate you are not going to sell anything , because your Ecat is a ghost…
