I just read this paper for the third time. This is a gem. These people
think and write like engineers rather than scientists. That is a complement
coming from me. They dot every i and cross every t. I can’t think of a
single thing I wish they had checked but did not.
In ever instance, their assumptions are conservative. Where there is any
chance of mismeasuring something, they assume the lowest possible value for
output, and the highest value for input. They assume emissivity is 1 even
though it is obviously lower (and therefore output is higher). The add in
every possible source of input, whereas any factor that might increase
output but which cannot be measured exactly is ignored. For example, they
know that emissivity from the sides of the cylinder close to 90 degrees
away from the camera is undermeasured (because it is at an angle), but
rather than try to take that into account, they do the calculation as if
all surfaces are at 0 degrees, flat in front of the camera. In the first
set of tests they know that the support frame blocks the IR camera partly,
casting a shadow and reducing output, but they do not try to take than into
account.
Furthermore, this is a pure black box test, exactly what the skeptics and
others have been crying out for. They make no assumptions about the nature
of the reaction or the content of the cylinder. They make no adjustments
for it; the heat is measured the same way you would measure an electrically
heated cylinder or a cylinder with a gas flame inside it. It is hands-off
in the literal sense, with only the thermocouples touching the cell, and
the rest at a distance, including the clamp on ammeter which placed below
the power supply. You do not have to know anything about the reaction to be
sure these measurements are right. There is nothing Rossi could possibly do
to fool these instruments, which the authors brought with them. They left a
video camera on the instruments at all times to ensure there was no
hanky-panky. They wrote:
“The clamp ammeters were connected upstream from the control box to ensure
the trustworthiness of the measurements performed, and to produce a
nonfalsifiable document (the video recording) of the measurements
themselves.”
They estimate the extent to which the heat exceeds the limits of chemistry
by both the mass of the cell and the volume of the cell. In the first test,
they use the entire weight of the inside cell as the starting point, rather
than just the powder, as if stainless steel might be the reactant. In the
second test they determine that the powder weighs ~0.3 g but they round
that up to 1 g.
They use Martin Fleischmann’s favorite method of looking at the heat decay
curves when the power cycles off. Plot 5 clearly shows that the heat does
not decay according to Newton’s law of cooling. There must be a heat
producing reaction in addition to the electric heater.
So is it just proton absorption?
I know neutron absorption is something that easily happens due to neutron having a neutra charge, a bit harder to do with a proton, but not impossible...
Professor Stremmenos weighs in. Translated from Italian.
18/5/13 - The direct testimony of Professor. Stremmenos
For the first time in a long time, Christos Stremmenos, a physicist who worked on the development of the ‘E-Cat and retired professor at the Department of Physical Chemistry, University of Bologna, he returned to public speaking LENR, and made at a conference on Energy Savings held in Bologna on 18 May, organized by the local Lions Club, with a popular talk entitled ‘cold fusion or LENR: cheap energy and no environmental impact. “
The intervention of prof. Stremmenos, estimated physical and former Ambassador of Greece to Italy in 1982-87.

Professor Stremmenos briefly touched many engineers to present his personal experience with Eng. Rossi and with the ‘E-Cat, which is the first test to subsequent developments, emphasizing the complete reproducibility of the phenomenon LENR below, the high stability of the reaction, the COP always greater than 6, the total absence of neutrons or radioactive waste, the intrinsic safety of the machine, as well as the very low cost of the thermal energy produced by it: less than 0.01 € / kWh.
Perhaps the most interesting of the intervention was to his testimony, unusual for the general public, on a test of an entirely different nature from the previous Eng. Rossi has made himself available to perform. In a reactor built by Stremmenos with a geometry and a technique different from those reactors Rossi, have been used “dust” normally used by ‘E-Cat. The results have been very positive, and this was a further confirmation of the validity of the process.

26/3/13 - successfully concluded third-party testing
We are happy to announce that, as announced in preview Eng. Andrea Rossi, in the week just ended saw the conclusion of the tests for ‘H ot Cat performed by independent third parties, whose specific aim was to ascertain, beyond a reasonable doubt, to be in the presence of a non-traditional source of energy COP and the actual equipment. Therefore, in the long validation phase, been going on for months with repeated tests on the three reactors made available by Leonardo Corp, accurate measurements were carried out by 11 between physics professors and experts from four universities in different countries.

Independent validators have had the opportunity to perform, in recent months, any kind of measurement wanted to reactors at their disposal: the only limitation was that it would open the reactors themselves, that contains trade secrets, and these were tested to the normal regime of power provided to the customers, ie not pushed to the maximum. They worked in complete autonomy, neither Rossi nor any person outside the group of validators participated in their briefing and planning of their measurements, and they wanted to pay for itself all the various travel expenses, room and board.
The test results will be published and made known in the next few months, but it is Rossi himself to leak the first rumors on his blog: “The validators have told me that the last test lasted 120 hours uninterrupted went well and that the ‘ effect is real beyond a reasonable doubt. “ He added Aldo Proia, commercial director of Prometeon: “The validation of an independent third party has a scientific purpose, but if you confirm what has been previously measured by Rossi is not difficult to imagine that it could soon have a major impact on both the energy world that on its financial markets. “
