Abstract: An experimental investigation of possible anomalous heat production in a special type of reactor tube named E-Cat HT is carried out. The reactor tube is charged with a small amount of hydrogen loaded nickel powder plus some additives. The reaction is primarily initiated by heat from resistor coils inside the reactor tube. Measurement of the produced heat was performed with high-resolution thermal imaging cameras, recording data every second from the hot reactor tube. The measurements of electrical power input were performed with a large bandwidth three-phase power analyzer. Data were collected in two experimental runs lasting 96 and 116 hours, respectively. An anomalous heat production was indicated in both experiments. The 116-hour experiment also included a calibration of the experimental set-up without the active charge present in the E-Cat HT. In this case, no extra heat was generated beyond the expected heat from the electric input. Computed volumetric and gravimetric energy densities were found to be far above those of any known chemical source. Even by the most conservative assumptions as to the errors in the measurements, the result is still one order of magnitude greater than conventional energy sources.

Conclusions
The two test measurements described in this text were conducted with the same methodology on two different devices: a first prototype, termed E-Cat HT, and a second one, resulting from technological improvements on the first, termed E-Cat HT2. Both have indicated heat production from an unknown reaction primed by heat from resistor coils. The results obtained indicate that energy was produced in decidedly higher quantities than what may be gained from any conventional source. In the March test, about 62 net kWh were produced, with a consumption of about 33 kWh, a power density of about 5.3 • 10^5, and a density of thermal energy of about 6.1 • 10^7Wh/kg. In the December test, about 160 net kWh were produced, with a consumption of 35 kWh, a power density of about 7 • 10^3W/kg and a thermal energy density of about 6.8 • 10^5Wh/kg. The difference in results between the two tests may be seen in the overestimation of the weight of the charge in the first test (which was comprehensive of the weight of the two metal caps sealing the cylinder), and in the manufacturer’s choice of keeping temperatures under control in the second experiment to enhance the stability of the operating cycle. In any event, the results obtained place both devices several orders of magnitude outside the
Even from the standpoint of a “blind” evaluation of volumetric energy density, if we consider the whole volume of the reactor core and the most conservative figures on energy production, we still get a value of (7.93 ± 0.8) 102 MJ/Liter that is one order of magnitude higher than any conventional source.
Lastly, it must be remarked that both tests were terminated by a deliberate shutdown of the reactor, not by fuel exhaustion; thus, the energy densities that were measured should be considered as lower limits of real values.
The March test is to be considered an improvement over the one performed in December, in that various problems encountered in the first experiment were addressed and solved in the second one. In the next test experiment which is expected to start in the summer of 2013, and will last about six months, a long term performance of the E-Cat HT2 will be tested. This test will be crucial for further attempts to unveil the origin of the heat phenomenon observed so far.

You will obey!
Obviously not, but like 0bama voters you're too ignorant to realize how ignorant you are. OR you're a shill. In either case you're wasting my time - go hump someone else's leg.

Rossi Manipulates Academics to Create Illusion of Independent Test
May 21, 2013 – By Steven B. Krivit –
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.
New Energy Times stopped counting the Rossi demonstrations after the 13th one on Feb. 12, 2012. (See Andrea Rossi Energy Catalyzer Master Timeline.)
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.
In response to a question from New Energy Times about whether he had full knowledge of how to perform and operate the experiment, Essén effectively confirmed that he had not replicated the experiment.
“No, but I am sure that I could repeat it with some effort,” Essén wrote.
Essén is the former chairman of the Swedish Skeptics Association, and his co-authors are Giuseppe Levi (University of Bologna), Evelyn Foschi (Italian National Institute of Nuclear Physics-Bologna), and Torbjörn Hartman, Bo Höistad, Roland Pettersson and Lars Tegnér (Uppsala University).
Andrea Rossi is a convicted white-collar criminal with a string of failed energy ventures. (Report #5: Rossi’s Profitable Career in Science) His most notorious endeavor was his effort between 1970 and 1990 to turn industrial waste into fuel. Rossi’s company produced only toxic waste and environmental damage to the land and groundwater in the Milan, Italy, area. (Rossi’s Italian Financial and Environmental Criminal History)
New Energy Times questioned Essén about the March 18-23, 2013, experiment that was, according to the paper, carried out by Essén and his co-authors.
SBK: In whose building/premises was the experiment performed?
HE: In Rossi’s facilities in Ferrara.
SBK: Who set up the experiment?
HE: Giuseppe Levi and Evelyn Foschi – within the constraints set by Rossi.
SBK: Who purchased or acquired the materials used in the reactor?
HE: Rossi.
SBK: Do you have full knowledge of the type and preparation of the materials used in the reactor?
HE: No.
SBK: Do you have full knowledge of how to perform and operate the experiment?
HE: No, but I am sure that I could repeat it with some effort.
SBK: Who acquired or supplied the instrumentation?
HE: Giuseppe Levi mainly, with some input from the Uppsala group.
SBK: Who tested and/or calibrated the instrumentation?
HE: Levi and Foschi did the main work, but several cross-checks were done by the rest of the participants. The temperature measurement cameras were checked on boiling water. The electric measurements were checked with standard resistors.
SBK: At any time during the 116 hours of the experiment was Rossi at any of the controls?
HE: Not that I recall. He showed us his ongoing projects in general but did not participate in the measurements.
SBK: Do you know of any other experiment performed in this field in which infrared measurements were made not just to acquire temperature readings but also to analyze for total heat enthalpy?
HE: No.
SBK: Do you know of any other experiment performed outside this field in which infrared measurements were made not just to obtain temperature readings but also to analyze for total heat enthalpy?
HE: No.
SBK: Is there any reason you did not use either mass-flow calorimetry or envelope calorimetry to analyze for total heat enthalpy?
HE: Yes, practical reasons. The current setup made it difficult. (Practical reasons determined by the reactor, its placement, and the available equipment.)
SBK: Who paid for the travel expenses of the Swedish participants in the test?
HE: All travel and living expenses were paid by Swedish and Bologna university sources.
Sure sounds like another demo. I thought the area looked shabby and what do you know, it’s Rossi’s ‘lab’.
I'm a chemist and well acquainted with the energy density of H2O2. Post your source.
Referencing yourself isn’t providing a source. Which test? Date?
Post to yourself if you want to quote something I posted. I don't want anything from you showing up in my "ping-box".
You will remember the statement from the gentleman who owns this forum....."...only trolls and disruptors will continue to post after being asked to stop". So, once again, I ask you to stop.
You ought to know better than to put credence in anything Krivit says. He is a technological know-nothing.
Measuring heat output by the means used is completely straightforward and a well-established means of doing so. The difference here is that the magnitude of the temperature changes and the rate of heat generation aresufficiently large to allow "air-cooling" calorimetry to be done. Previous researchers in LENR have not successfully generated heat and temperatures of this magnitude, and could thus not use this method.
The system is cooled by a combination of radiative emission of heat, and convective removal of heat by thermally initiated air movement. All you need to calculate the convective heat loss is room temperature, the temperature of the hot object, and the size and shape being cooled.
As to the fact that the device was "in Rossi's facility" means precisely nothing. He was never in the room, and the testing parties had full and free access to all aspects of the system except for the internals of the control circuitry, which is, of course, proprietary.
Introducing H2O2 into that experiment was physically impossible.
It "might" have been possible to substitute H2O2 into one of the experiments that ran from a tank under pump pressure, but my opinion is that even there, the H2O2 would have made itself known by offgassing oxygen bubbles due to traces of metals contamination of the tank or tubing walls.
And the effluent from decomposing H2O2 is VERY different in appearance from condensing steam....you basically end up with foam.
Really?

I wonder if that explains why he dumps the heated water down the drain, instead of letting anyone examine it?
Introducing H2O2 into that experiment was physically impossible.
Why would you change the subject? You said, "To yield the needed energy, the H2O2 would need to be very concentrated"
Clearly, that's not true.
He gives the impression that he knows a lot more than you do and is a lot more professional expressing it.
Who are you to judge Krivit?
Perhaps that's because he's using more hot plates. How can anyone accept the word of a con artist like Rossi and his cohorts as facts?
I don't think a decomposing pure solution of H2O2 will foam. You would need the addition of something like blood or soap for that to happen. A chemist should know that.
