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.

Burden of of independence? Where else does this exist in scientific endeavor?

It exists because you made the claim of independence. The only way you can back it up is to use a specious definition. When pressed for specifics you become evasive.

Be careful. The mods might consider that to be engaging in a flamewar. /s

hmmm, even more crickets

[Moonman62]

Why do I need to list this person’s credentials? You got a problem, you chase it down.

You're the one with a problem because you are claiming that this is a big deal for Rossi, but you don't even know the credentials of some of the people listed as authors.

Until then, like in basically every other scientific endeavor, the person’s credentials are assumed to be worthwhile.

Getting a "report" listed on arXiv isn't necessarily scientific, so all you've got is an assumption.

You should expect criticism when you promote a con artist on FR. If you don’t like it then keep it on Vortex where kooks are welcome.

[Kevmo]

it isn’t peer reviewed.
***Peer review takes several months, or did you not know that? I doubt you knew it, but at any rate...

dilute H2O2 cannot account for the energy densities reported in this independent report

That's a relief, because the first test you had me look at would have worked with weaker than drug store H2O2.

And the scientists don’t test for that.

When Rossi was testing his own and wouldn't let the witnesses touch anything, and was pouring the "coolant" down the drain, you're right, the scientists didn't test for that.

[Moonman62]

So you’re admitting that the “report” isn’t peer reviewed. Thanks.
