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 manufacturers 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.
And yet, they publish this independent report today.

Dogbert cuts right to the chase.
Unless they use dilute H2O2.
And the scientists don’t test for that. Gosh, as pedestrian as I am, I would have tested for it.

I’ve noticed that the dumber the idea the quicker the jackasses of fr who believe in it are to dive in with the first insult. Like I said put your money where your big keyboard brave mouth is and have the last laugh or not as is most likely the case. Cold fusion is like he pill you added to the water that you filled your gas tank wih in the ‘50s. “for the true believer no proof is necessary and no disproof possible” Stuart Chase
Nice try, but you’re still in the juvenile range, not rising to the level of series. Try again. Shirley you can rise above punk level. Give it a hugh try, little one.

dilute H2O2 cannot account for the energy densities reported in this independent report
zzzz
True. But measurement of temperature is the key that allows the calculation of heat production. This is a very simple convection-cooled system. I suspect there are dozens of math models that will let you plug in a size and shape being cooled, and its known temperature, and have it cough out a pretty good measure of heat production.
You keep repeating that. Unfortunately, it isn't true. To yield the needed energy, the H2O2 would need to be very concentrated and would very likely signal its presence by offgassing oxygen (hydrogen peroxide decomposition is catalyzed by MANY metals).
Isn’t it possible to work backwards from the data presented to generate heat production from measurement of temperature over time at 1Hz?
I think that’s a significant statement.
I predict crickets in your future.
you’re boring
Bwahahahaha ... you don’t even know the main players in the decde or more long controversy, yet you pretend to be so expert that you can ridicule those who’ve kept up. LOL I sure am an old boring freeper. BTW, try not to insult FR when you try to be adult.

***H2O2... sounds chemical. From the article:
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.
