It links to this PDF that is the report of the folks who reviewed the Rossi E-Cat:

So a pretty good selection of folks looking at it.
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.
Looks like it’s real.
It’s hard to fake an order of magnitude of excess heat over 116 hours…
The tests held in December 2012 and March 2013 are in fact subsequent to a previous attempt in November 2012 to make accurate measurements on a similar model of the E-Cat HT on the same premises. In that experiment the device was destroyed in the course of the experimental run, when the steel cylinder containing the active charge overheated and melted.
So “control issues” with thermal production to the point of melting steel… Um, I think that’s pretty strong evidence just on its own…
You just gotta love the understated way things are put in academic papers…
The partial data gathered before the failure, however, yielded interesting results which warranted further in-depth investigation in future tests. Although the run was not successful as far as obtaining complete data is concerned, it was fruitful in that it demonstrated a huge production of excess heat, which however could not be quantified. The device used had similar, but not identical, features to those of the E-Cat HT used in the December and March runs.
Besides some minor geometrical differences, in the E-Cat HT used for the November test the charge in the inner cylinder was not evenly distributed, but concentrated in two distinct locations along the central axis. In addition, the primer resistor coils were run at about 1 kW, which might be the cause of the ensuing device failure. For these reasons, a more prudent reactor design was chosen for the test held in December and March, by distributing the charge evenly along its container cylinder, and limiting the power input to the reactor to 360 W.
It’s damned hard to melt a steel cylinder of any size with just 1 kW. Make it hot, sure. Melt it? Not usually… Make a nice room heater, but not melting. Something else was going on, for sure.
A rather spectacular picture follows, glowing red / orange / yellow, with this caption:
Figs. 1-2. Two images from the test performed on Nov. 20th 2012. Here, the activation of the charge (distributed laterally in the reactor) is especially obvious. The darker lines in the photograph are actually the shadows of the resistor coils, which yield only a minimal part of the total thermal power. The performance of this device was such that the reactor was destroyed, melting the internal steel cylinder and the surrounding ceramic layers. The longterm trials analyzed in the present report were purposely performed at a lower temperatures for safety reasons.
The electrically powered heater shows up as a thermal shadow… and melting ceramic layers? Oh dear…
We also get the fluctuating magnetic field that we saw in earlier devices:
Device and experimental set-up
The E-Cat HT-type device in this experiment was a cylinder having a silicon nitride ceramic outer shell, 33 cm in length, and 10 cm in diameter. A second cylinder made of a different ceramic material (corundum) was located within the shell, and housed three delta-connected spiral-wire resistor coils. Resistors were laid out horizontally, parallel to and equidistant from the cylinder axis, and were as long as the cylinder itself. They were fed by a TRIAC power regulator device which interrupted each phase periodically, in order to modulate power input with an industrial trade secret waveform.
I’d wager high frequency possibly square wave.
And it can’t be some kind of chemical energy storage / indirect fuel burn:
Figure 9 shows the “Ragone plot of energy storage”, a typical diagram in which specific energy is represented as a function on a logarithmic scale of the specific power of the various energy storage technologies [Ref. 7]. Power density and thermal energy density found for the E-Cat HT place this device outside of the area occupied by any known conventional energy source in the Ragone chart.
We also get to know why the tests took so long. One melted. Another was not set up as they wanted. So things got done over.
This test enabled us to pinpoint several procedural issues, first of all the fact that the device was already in operation when the trial began. This prevented us from correctly weighing the device beforehand, and conducting a thermal analysis of the same without the powder charge, prior to evaluating its yield with the charge in position. The choice of placing the thermal camera under the E-Cat HT should also be considered unsatisfactory, as was the impossibility of evaluating the real emissivity of the cylinder’s paint coating. All these issues were taken notice of in the light of the subsequent test held in March. This was performed with a device of new design, as a result of technological improvements effected by Leonardo Corporation in the intervening months.
So they finally got it done the way they wanted. This later test uses a design made for continuous use and is somewhat different:
The E-Cat HT2’s power supply departs from that of the device used in December in that it is no longer three-phase, but single-phase: the TRIAC power supply has been replaced by a control circuit having three-phase power input and single-phase output, mounted within a box, the contents of which were not available for inspection, inasmuch as they are part of the industrial trade secret. But the main difference between the E-Cat HT2 and the previous model lies in the control system, which allows the device to work in self-sustaining mode, i.e. to remain operative and active, while powered off, for much longer periods of time with respect to those during which power is switched on. During the test experiment we observed that, after an initial phase lasting about two hours, in which power fed to the resistor coils was gradually increased up to operating regime, an ON/OFF phase was reached. In the ON/OFF phase, the resistor coils were powered up and powered down by the control system at regular intervals of about two minutes for the ON state and four minutes for the OFF state. This operating mode was kept more or less unchanged for all the remaining hours of the test.
It looks to me like the world just changed…
For power density we have:
(816-283.5)/0.001 = 532500 [W/kg] ~ 5 · 105 [W/kg] (28)
Thermal energy density is obtained by multiplying (28) by the number of test hours:
532500 ·116 = (6.2 ± 0.6) · 107 [Wh/kg] ~ 6 · 107 [Wh/kg] (29)
It is easy to infer from the Ragone chart, another example of which may be seen below in fig. 15 below, that these values place the E-Cat HT2 at about three orders of magnitude beyond any other conventional chemical energy source.
I think we’re hearing the Fat Lady singing…
