Thank you Horace, I think you really have driven the final nails into
the Rossi coffin, with your exemplary analysis of the percolator
effect, along with cogent remarks about the endless wan discussions.
Meaningful data can be obtained through the performance of well
calibrated, and preferably dual method, calorimetry on the device, as
a black box, that establishes a complete energy balance for each run.
Use of control runs is also a standard method, and useful for
calibrating the calorimetry. A thermal pulse method is also a useful
check on calorimetry functions during run times. Anything less this
kind of professional calorimetry can not be relied upon. Anyone who
has actually done calorimetry are keenly aware of the difficulty of
getting it right. Sparging steam into a bucket, though far better
that other steam methods applied to date on Rossi's devices, and
publicly disclosed, has numerous serious drawbacks, which have alreadybeen discussed.
I’m very happy to be able to have another guest post today — this one written by Dr. Johannes Hagel, of Neuss, Germany.
Being a physicist I consider the announced test of Andrea Rossis E-Cat at Uppsala as one of the most important of all the series of tests we have been seen so far. This for the following reason:
In the announced test for the first time there will be made use of a heat exchanger which transfers the energy of the steam output into a secondary circuit for heating water without boiling it. At least that is how I understood it from Rossi’s description. This means that a certain amount of water per time unit will pass through the heat exchanger with a given entrance temperature T1 and a larger exit temperature T2.
It is then very simple to compute the amount of energy which has been necessary to obtain this temperature difference at a given water flow through the exchanger (in fact a simple multiplication of three numbers). In addition, this energy measured will give an “approximation from below” to the true energy output of the E-Cat. This is because a heat exchanger, due to the laws of thermodynamics (as well as to non-perfect insulation) will never reach 100% efficiency.
However, with this method we will be sure that at least the measured energy in the secondary circuit has indeed be released by the E-Cat. This was not so easy to state using the old method of temperature measurement of the direct steam output as it has been done so far. This is due to a difficulty of distinguishing between wet and dry steam, wet steam still containing some water in it. This remaining water has not been vaporized, i.e. the vaporization energy necessary to transfer water to steam (phase change!) has never been applied to it. Hence the thus computed energy output can easily be overestimated. If however, one transfers all the energy of the steam (dry or wet) via the heat exchanger, and uses it for heating water without boiling it things become very clear.
Of course the upcoming test has to be run for a sufficient amount of time to exclude a chemical process inside the E-Cat which could account for the observed energy output. As far as I understood the present E-Cat is considerably larger than the previous one. For the original one Prof. Levi (University of Bologna) excluded a combustion process after a test run of 18 hours. From the images shown I would guess that the inside volume now is at least three times the one before and thus the test should be extended for at least 60 hours or even more to exclude common energy sources inside.
However if all this is observed and any type of “hidden energy transfer” from the outside into the E-Cat (e.g. based on micro waves etc.) can be excluded then I would consider this type of test as a very rigorous and would be extremely pleased seeing a positive result.

Dear Pietro F:
Yes we have very big financial problems, because I have spent on this all the money I had, and sold all I had, also because the Customer we counted on could not maintain his financial engagements and this has left the ship in the middle of the ocean without oil for the engine. But we are going through, the 1 MW plant will be ready for the end of October for the test anyway, we are close.
Yes, we will organize e new very important test in Uppsala, and this time we will make the calorimetric measurements in a new way, suggested by the Professors: the steam circuit will be a closed circuit with a condenser and will exchange heat with a flow of liquid water: basically, we will have a primary circuit of the E-Cat and a secondary circuit through a radiator, and the energy will be calculated not from the delta T of the input/output of the reactor, but from the delta T of the secondary, which will exchange the heat by means of a heat exchanger. Of course the calculation of the energy produced will be in our disadvantage, because the heat exchange system has not a 100% efficiency, but I can accept it, because our energy gain is very high. The operation will be made also with self sustaining mode. We are already making this test in our factory, and the results of the energy gain are very close to the measurements we made in past. I am very satisfied.
Warm Regards,
A.R.

Je parie que le conteneur va se perdre, ou bien que Rossi dira que ca a été endommagé pendant le transport et qu' il ne peut pas faire la démo.
ou dans l'espace sans propulsion au choix et sans back up il a vendu sa maison pour financer le reste, mais que le test aura de toute façon lieu car la machine est prête. Il a soit disant laché toutes ses économies dans l'histoire, soit c'est du pipo, soit il y croit vraiment si tu es capable de bricoler des machines frigorifiques haute pression ( certif iso, soudeurs agréés et tout et tout ) tu es capable de fabriquer des réacteurs de Focardi-Rossi. Mais tant qu'il n'y a pas de preuve indiscutable, inutile que je m'amène chez mes copains. )Revenir vers « Innovations, inventions, brevets et idées pour le développement durable »
