On May 16, Hanno Essén, a theoretical physicist and lecturer at the Swedish Royal Institute of Technology, submitted a paper to arXiv, the physics pre-print server, and claimed that he and several co-authors performed an independent test of an E-Cat device that was built by Andrea Rossi. Essén submitted a revised version of the paper on May 20.
The authors of the paper did not perform an independent test; instead, they were participants in another Rossi demonstration and performed measurements on one of Rossi’s devices in his facility.
The authors of the paper lack full knowledge of the type and preparation of the materials used in the reactor and the modulation of input power, which, according to the paper, were industrial trade secrets.
The authors didn’t perform any calorimetry and used a method to measure temperature to extrapolate output power that neither they nor anyone in the field of low-energy nuclear reaction research has ever used to analyze for heat power or energy.
Krivit's agenda is obviously to report the good and the bad of LENR/cold fusion, whereas yours is to promote the con-artistry of Rossi.
and his ridiculous article is being ripped to shreds across the internet, such as on Vortex-L.
And here is Vortex-L's own description of what they are:
The Vortex-L list was originally created for discussions of professional research into fluid vortex/cavitation devices which exhibit anomalous energy effects (ie: the inventions of Schaeffer, Huffman, Griggs, and Potapov among others.) Currently it has evolved into a discussion on "taboo" physics reports and research. SKEPTICS BEWARE, the topics wander from Cold Fusion, to reports of excess energy in Free Energy devices, gravity generation and detection, reports of theoretically impossible phenomena, and all sorts of supposedly crackpot claims.Sounds like a good place for you to hang out, rather than posting this trash on FR.
If he goes to jail, you'll claim he was framed just as you claim this latest magic trick is independently and scientifically tested.
The authors of the paper lack full knowledge of the type and preparation of the materials used in the reactor and the modulation of input power, which, according to the paper, were industrial trade secrets.
***It’s a black box test.
They lacked knowledge of the modulation of input power. That’s a huge red flag. Unless you’re color blind.
So you think someone can send in enough input power through the wires, not be detected by a modern multimeter, reach a temperature that melts ceramic but keep those thin wires together. Fascinating hypothesis. That would make Rossi a masterful magician, and he could have a career in his own right just for that trick alone.
Your skeptopath positions are getting whittled down incessantly, to the point that you’ll soon realize you’ve painted yourself into a corner.
Those are pertinent criticisms, but they are not dispositive of Rossi’s claims, let alone of the entire field.
Not a chance I’ll give up my skepticism as long as Rossi is in the room. He’s a con man and he’s still running his con.
Krivit really is getting shredded on the internet. Hits for the last 24 hours on google for Krivit “cold fusion” yielded only one positive comment about him.
best of luck with that
Eventually, you’ll buy a LENR water heater and say to yourself, “why didn’t I understand the technical arguments at the time?”
An independent test is an independent test, until skeptopaths get involved.
Here’s a simple question for you, that you will not answer.
What happens to a thin wire (as shown in the videos & pictures) when you heat it up to the point that ceramic glows?

Before we get too excited. I think two questions need to be answered.
1. When was the calibration done and under what conditions. The amount of heat being radiated depends on the value of the effective total emissivity of the surface. This value will change with time and temperature. Therefore, the value needs to be determined as a function of temperature both before and after the hot-cat was heated. Details about how the temperature of the surface was determined also need to be provided. A detailed description of the test is required before these claims can be accepted.
2. How long does the hot-cat function at such high temperatures. This time will determine whether the device is a practical source of energy. The extra energy may be real, but if it only lasts a short time before the NAE is destroyed, the value of the design is limited.”
I would also ask what equipment was supplied by Rossi and what was provided entirely by the experimenters. I have not finished reading the paper but I am skeptical about the accuracy of both input power and out. As in the past, it is possible, even likely, that Rossi (or his surrogates who may have present during the experiments) found a way to fool the scientists.
It would be much more convincing if, instead of going to this very demanding and difficult to understand test, Rossi had simply had earlier tests repeated with PROPER CONTROLS AND CALIBRATIONS. He has **always** refused to do this. A perfect example of a test that would need to be properly redone was Levi’s original using liquid flow calorimetry but no proper calibration.
Also convincing would be if Rossi could produce an independent and credible customer who had bought a “megawatt plant” and had, in fact, extracted substantial power from it over a long period of time– for example heating a building or a chemical process plant.
Without more evidence, it is very hard to believe that this is not just another case of Rossi cleverly fooling people who very much want to believe him.
Rossi has presented a very strange method of proving his technology just as he did in the past. Much easier and more straightforward ways are available with the old ecat and lower temperatures which do not require measurement of radiative heat transfer.
Sounds great! Will it happen before 2050?
Why is “heavywatergate” included in your search? Doesn’t that bias the results?
