Here are some recent comments from Andrea Rossi on the performance of the new version of the Hot Cat that he is currently testing. Most recent information at the top:

UPDATE #5 (July 28, 2015)

Andrea Rossi has just posted that the first model of the new Hot Cat has broken down. He wrote:

Tom Conover:
As I explained in another comment on this blog few hours ago, the new Hot Cat has been destroyed, but we are making another with a correction that should resolve the problem.

It makes me wonder if the Hot Cat went into some kind of thermal runaway mode. Rossi says that over the years hundreds of reactors have been destroyed by one means or another, sometimes intentionally. His experience should be helpful in making the needed adjustments.

These are exciting times and Rossi (and his sponsors) and the research team of Levi, Foschi, Höistad, Pettersson and Tegnér, as well as Hanno Essén, are to be commended for their tenacious pursuit of what at times must have seemed a thankless job. The world looks forward to more. – Michael C.H. McKubre

A team of scientists from Italy and Sweden have released a second, more substantive test analysis of the Andrea Rossi E-Cat. The report, “Observation of Abundant Heat Production from a Reactor Device and of Isotopic Changes in the Fuel” , was released on October 8 based on a 32-day test done in March 2014. The same team (Giuseppe Levi, Evelyn Foschi, Bo Höistad, Roland Pettersson, Lars Tegnér, Hanno Essén) tested an earlier version of the E-Cat in spring 2013 and released a similar, though not as conclusive, report. The new report concludes with a clearly written and positive statement:


In summary, the performance of the E-Cat reactor is remarkable. We have a device giving heat energy compatible with nuclear transformations, but it operates at low energy and gives neither nuclear radioactive waste nor emits radiation. From basic general knowledge in nuclear physics this should not be possible. Nevertheless we have to relate to the fact that the experimental results from our test show heat production beyond chemical burning, and that the E-Cat fuel undergoes nuclear transformations. It is certainly most unsatisfying that these results so far have no convincing theoretical explanation, but the experimental results cannot be dismissed or ignored just because of lack of theoretical understanding.

All well and good. Is this confidence justified by the words in the report? Is there evidence of excess heat? My impression is “Yes” (but see below). Is this evidence unambiguous? Not as presented. Is there evidence of nuclear transformation? Yes, very clearly, but questions remain to be answered (or, in some cases, asked). Do the heat and nuclear production correlate quantitatively? Yes, possibly. Is the report perfect? No, no report is perfect, but this one is imperfect in little ways and large. There is curious inattention to detail—surprising for a document as delayed, anticipated and important as this. When asked to provide a review (sight unseen) I agreed; this is important. But I also realized that unless the report was perfect in every detail, whatever I wrote would annoy somebody. Here goes.

For the proponents of condensed matter nuclear science (CMNS) this report provides valuable impetus and strong support for the case that nuclear effects occur (implicitly by novel pathways) in the solid state. More importantly, the report provides concrete and testable information about fuel and products, potentially of two separate branches of CMNS, of the sort to make theorists on both sides of the “reality question” very happy indeed. Have we risen to the standard of Dick Garwin’s “undoubtedly”? No, although he should be happy that multiple cups of tea might soon be available—perhaps on demand.

Although highly interesting, this report has problems at several levels that render direct interpretation difficult or impossible without further information and clarification. This is a shame and undoubtedly a source of great frustration to the CMNS community. There are substantive missing or broken issues dealing with the essential issues of calorimetry and sampling. There are also “minor” or ancillary points that I will attempt to outline to improve technique and reporting. The latter do not change the conclusions but do affect credibility. You will note that this review contains more questions than answers. Not all of these questions required answers before the experiment was run or the report written but, in my view, many of them should have been addressed.

Let’s start with the calorimetry, the balance (or reported imbalance) between power input and power output. We begin with the input energy. I have only minor issues with the technique employed for input power measurements and the interpretation of values. Measurement of three-phase power is a standard matter that is critical in numerous industries. The community of scientists and engineers knows how to do this precisely and accurately on scales extending from well below to well above the power levels in this experiment. There is every indication that the authors of this report are well aware of possible pitfalls and have taken care to address them. They address the issue of unmeasured current flowing in unseen “ground loops” by employing similar meters upstream and downstream of the load. These meters have harmonic monitoring capability in case unmeasured high frequency components contribute significantly to the input energy. As has been demonstrated many times (and again in this report) neither issue is “really real.” But questions have been asked about other similar experiments; this report anticipates them and answers them, before being asked.

First class, perhaps overkill, but one issue I have with the input power measurement is that the claimed uncertainty of ±10% seems far too large. My colleagues and I have considerable experience with almost identical measurements over a range of power scales from the small to the large. After ICCF17 in 2012, Fran Tanzella and I traveled to China to conduct power measurements and perform “calorimetry” on the 100-200 KW scale which we were able to accomplish effectively at the ±1% level of accuracy in an industrial setting using WattNode power-to-pulse converters. These meters are cheap and reliable, and can be used with good accuracy provided that current sensors are well matched to the voltage and current. For any sort of electrical engineer the measurement of power delivered is a “no brainer.” This is not an issue for this report but I would like to see the authors re-think and re-justify their asserted levels of accuracy in input power and energy measurement.

The report states: “The reaction is primarily initiated by heat from resistor coils around the reactor tube.” Do we know that this is the configuration (were the authors permitted post-test examination)? What does “primarily” mean? The report states: “In addition, the resistor coils are fed with some specific electromagnetic pulses.” What kind of electromagnetic stimulation? How much? How was this measured? When? Why? I do not expect an answer to the last but the rest need to be addressed quantitatively.

As a final point on input power I was surprised to see that this was measured not at the “calorimetric boundary” but at the power supply. This necessitates a correction to the power delivered to the test since the lead wires have resistance. The correction is small and appears to have been done correctly. It is, however, always better to avoid mathematical corrections by placing the voltage sense contacts at the points that define the boundaries of the interrogated heat.

The mode of calorimetry employed to measure the output power and by integration energy, is one with which I have little direct hands-on experience. When I first read the report I was inclined to accept the output power measurement at levels of say ~±10% accuracy (subject to quantitative verification using a finite element heat model). [Note that the report assigns ±1% to the accuracy of the output and ±10% to the input.] My intuition/experience would reverse these numbers. Heat lost from hot objects by convection and radiation is, like electrical power measurement, a very standard and well-documented engineering procedure with history extended back over 100 years. We know how to do this. Having said that, the complexity (and uncertainty) of the E-Cat structure render the interpretations “difficult,” or worse, “ambiguous.” Are these difficulties and ambiguities sufficient to negate the value of the report? I don’t think so, but verification is required. Let’s look at some of the issues.

Of primary concern is the complete absence of relevant pre- or post-test calibration. The mathematical description of heat losses from a structure with multiple parts and awkward geometry is not difficult but contains many terms and several assumptions. Perhaps with more direct experience I could trust the equations and assumptions to do their job, but I do not have that experience. Neither do the authors, nor does most of the “audience.” The only way to handle such uncertainty is via relevant calibration, ideally under identical conditions at and surrounding the operating point. The calibration that was performed was at a single point well below the points of ultimate operation. This is bad and bad. We need to determine the shape of the performance manifold empirically, ideally bracketing all points of operation. This was not done.

The “active” experiment operated at two base levels of heat output: ~1250W and ~1400W. The report says that dummy power was limited to 500 W. Even if the system had simple geometry and the calibration function was linear this would be an extraordinary departure from accepted and acceptable protocols. The explanation given for this divergence is not plausible. The authors claim that “some Inconel cables have a crystalline structure that is modified by temperature, and are capable of withstanding high currents only if they are operated at the appropriate temperature. If these conditions are not met, microscopic melt spots are liable to occur in the cables.” Even if true the options are several:

1) If you really cannot (or are not permitted to) operate above 500 W, use three calibration steps (say 300, 400 and 500W) to determine the shape of the calibration manifold. Extrapolation is bad but better than nothing.
2) Slowly increase the power while monitoring the resistance to anticipate and avoid “microscopic melt spots” by observing (and avoiding) points at which resistance rises rapidly in an unexpected profile.
3) Employ Joule calibration after the test when the operating regime has been determined. The internal sense control thermocouple (whose data are missing from the report) could easily be re-inserted after the products have been removed and then re-bonded into place for calibration.

The inability or unwillingness to do one or all of these things is a glaring deficiency in the thermal output record. That is not to say that this record is incorrect, but we cannot be certain that it is correct and the measurement uncertainty is undefined.

In the absence of calibration suitable and sufficient for accurate quantification, what can we learn qualitatively using the experimental data from the active run as its own “self-calibration”? On page 7 of the report the authors state: “Subsequent calculation proved that increasing the input by roughly 100 watts had caused an increase of about 700 watts in power emitted.” This is interesting. The shape of the output vs. input power curve is observed (or implied) to strongly curve upwards in a manner completely inconsistent with the Stefan-Boltzmann law for radiative heat loss. It is also inconsistent with simple convective heat transfer but several issues need to be addressed before we can claim this as a qualitative or even “semi-quantitative” measure of excess heat production:

1) The issue of alumina emissivity is adequately handled in the report (it is needed to calibrate the temperature measurements) but not the issue of transparency. Without getting too technical, the rate of radiant heat release is determined optically. At issue is the extent to which the camera measures directly the temperature of the heating wires and the putative source of the “fuel” directly transmitted through the alumina container, rather than the surface as assumed in the heat calculations. This is not an area of my expertise. The arguments are subtle and may result in under, over, or accurate measurement of radiant heat loss rate.
2) No independent temperature measurement is provided of the contents internal to the E-Cat where the heat sources are located. Such a sensor was apparently present but the data were not provided or (apparently) analyzed. This is of concern as these data could provide strong supporting evidence for the radiant heat calculation and Point 1. Furthermore, nickel melts at 1455°C and the different Inconel alloys melt in the range 1390 – 1425°C, with the surface temperature stated in the report to reach 1412°C, and the heat sources known to be inside. Thus the “fuel or catalyst” (Ni), the heater wires and the inserted thermocouple sheath are all at significant risk of melting if the optically determined alumina surface temperature is correctly measured. Was this measurement correct or was the reactor on the cusp of failure when it was shut down?
3) Radiant heat loss rates increase with temperature so (ignoring the issues of Point 1) an increase of ~700 W output caused by ~100 W increase in input is definitely not expected. The other major term is convective loss, which increases roughly linearly with temperature so that such a steep upturn would be unexpected. However, convective losses are strongly affected by air movement both natural convective eddies and bulk air movement. No attempt was made to control air movement using closures or shields so the convective state of the air surrounding the E-Cat source is unknown and cannot be determined. The “good news” is that when the maximum output was achieved at 906 W input, and 2886 W total output, the convective loss term was only ~15% (431 W) so we really only need concern ourselves with convection (at the, say, 10% accuracy level).

I could go on. There are many tiny details of calorimetry that need better exposition and it is to be hoped that this will occur through open discussion.

I now turn attention to the “fuel” and products, and sampling. The fueling process is described in the report thusly:

After 23 hours’ operation, the dummy reactor was switched off and disconnected from the power cables, to allow for one of the caps to be opened and the powder to be inserted. The powder had been previously placed in a small envelope, weighed (about 1 g), and then transferred to a test tube so that Bianchini could perform radioactivity measurements on it, after placing it in a low background lead well. Lastly, the contents of the test tube were poured inside the reactor, in the presence of a member of the experimental team.

From the perspective of a chemist I have several issues with this stated procedure. A small envelope? What kind of envelope? About 1 g? How much mass exactly? How was the starting sample taken? By whom, with what tools, using what procedure? The report states, “It should also be noted that our total sample was about 10 mg, i.e. only a small part of the total fuel weight of 1 g used in the reactor. The sample was taken by us at random from the fuel and ash, observing utmost care to avoid any contamination…An arbitrary sample of different granules is chosen for the analysis.” How big is a granule? How many were selected? One percent (10 mg of ~1000 mg) is a pretty small sampling unless we can trust the randomness of the sample. How was sampling randomized? By whom was this done using what criteria?

The report states: “The reactor…is charged with a small amount of hydrogen-loaded nickel powder plus some additives, mainly lithium” but also “it is plausible that the fuel is mixed with the standard lithium aluminum hydride, LiAlH4. Further evidence of that is obtained from the ICP-AES analysis which shows that the mass ratio between Li and Al is compatible with a LiAlH4 molecule.” I do not want to quibble but LiAlH4 is not mainly Li. And the fate of the Al is not mentioned in the analysis of the products. This might be a nice marker of metal loss and isotopic shifts, especially since natural Al is mono-isotopic.

All this is minor detail that should nevertheless have been addressed. What is not minor is the fact that Rossi himself made the fuel addition (using an undescribed procedure) albeit “in the presence of a member of the experimental team.” The fact that the reactant was inserted and extracted by Rossi with his own hands does not invalidate the technical data. After all, this is how most experiments are performed without chaperone. It does raise a question however and all questions unanticipated and unanswered in a report (particularly one of this potential consequence) tend to diminish credibility and thus significance.

Finally we get to products. When reading the report for the first time the thing that struck me with greatest pleasure was the apparent isotopic transformation from fuel to product. So many of us for so many years have been stating: “Show us evidence of nuclear products with non-natural isotope distributions and we will believe that the element was created or transformed.” This report presents clear evidence thusly: “The lithium content in the fuel is found to have the natural composition, i.e. 6Li 7% and 7Li 93%. However at the end of the run a depletion of 7Li in the ash was revealed by both the SIMS and the ICP-MS methods. In the SIMS analysis the 7Li content was only 7.9% and in the ICP-MS analysis it was 42.5%.” This finding is taken to a logical conclusion with an argument relating mass transformation to energy. The report speculates: “the depletion of 7Li might be due to the reaction p + 7Li arrow 8Be arrow 4He + 4He” and goes on to calculate: “If each 7Li nucleus releases about 17 MeV we find then that the total energy available becomes 0.72 MWh. This is less than the 1.5 MWh actually produced in our 32 days run, so more energy has to come from other reactions.”

Other reactions apparently occur: “Evidently, there is also an isotope shift in nickel. There is a depletion of the 58Ni and 60Ni isotopes and a buildup of the 62Ni isotopes in the burning process.” There is, however, no attempt at a mechanism or an energy calculation to rationalize the missing ~50% energy beyond a repeated wistful appeal to the “Coulomb Barrier” that has relevance only to the pairwise interaction of charged nuclei (that clearly did not happen).

In addition to an evident lack of even an overall mechanism to explain half of the produced energy several other problems occur:

1) If one were to reshuffle the neutrons of the five stable Ni isotopes in the directions of the revealed changes we would have a great deal of energy—possibly far too much, in fact, depending on the sources of the “new” neutrons.

2) If the “fueling” of the Ni half of the putative excess heat involves the Ni light isotopes, all of these are essentially depleted and yet the reactor was continuing to increase its rate of energy production (excess power). Rates of reaction are not expected to increase (one might state more strongly “are known not to increase”) with near complete loss of fuel. If the reactor had been run for a day or two more would we have seen the rate of heat evolution decline to zero?

3) One might perhaps argue that the Ni was “burned” first before the reaction started to consume 7Li but this brings up another issue. Whatever mechanism we postulate for the “Ni burn” this is hardly likely to be in any way similar to that tentatively proposed for Li. This means that we are required to explain not one but two new processes that occur under near-identical conditions.

4) The authors commenting on their analyses state that some elements present in the fuel samples are not present in the product samples. Just as for Al these elements are markers. We have three possibilities: (i) these contaminants (or deliberate additives) are participating in the reaction; (ii) they volatilized and exited an imperfectly sealed reaction chamber; (iii) the starting and ending “samples” are not the same. Whichever, I would like to know the answer and see some discussion of it. Possibly this is poor wording but it needs to be made clear.

5) I took issue with the insufficiently well specified process of sampling the fuel mix prior to introduction into the E-Cat. The product sampling is even less well specified and described. How was this done? Who was present? Who did what with what apparatus? Was this recorded on video? What was the chain of custody of possibly the single most important sample ever generated in CMNS studies? The authors and workers had no reason except their calorimetric results to believe that the sample was as important as it apparently was. But just to make sure we need to develop an agreed upon sampling technique and establish a documented chain of custody for any future samples. A mandatory requirement for an independent test is an effective decoupling of interested parties from significant activities.

And there must be future samples. This was not a replication of a previous demonstration. Rossi clearly had experience with this device operating in this mode but for the authors of the report this was a new and one-off experiment. One experimental result equates to zero experimental results. Nothing in science can be known without repetition.

As a final non-technical point, let me extol the virtues of technical and copy editing. I realize this report has not been submitted for publication and is therefore “in process” but little things distract from the bigger points that are being argued. In the conclusion the report states: “the ash composition from SIMS is: 58Ni (0.8.%), 60Ni (0.5%), 61Ni (0%), 62Ni (98.7%), 64Ni (0%).” These percentages add to 100.4% because the 58Ni analysis is mis-quoted from Appendix 4 which states 0.3% for this isotope. The natural abundance of Ni isotopes quoted throughout the report add to 100.6% because the abundance of 61Ni is listed as 1.8% in the report rather than 1.14%, according to Wikipedia. This does not make any difference to the conclusions but the reader is forced to ask “if these small details are wrong what else might be?”

On the whole I am encouraged. Considerably more work is obviously needed to validate the adopted mode of calorimetry and support better sampling and testing. But we are given something we can sink our teeth into both experimentally and theoretically: testable fuel(s) to products(s) nuclear burn at temperatures that have practical, economic and social potential. These are exciting times and Rossi (and his sponsors) and the research team of Levi, Foschi, Höistad, Pettersson and Tegnér, as well as Hanno Essén, are to be commended for their tenacious pursuit of what at times must have seemed a thankless job. The world looks forward to more.

Rossi Should Not Reveal The Catalyst, Until Intellectual Property Rights Are Protected

Property of Andrea Rossi

Property of Andrea Rossi


I have an interest in science, but as I am not a scientist, I care much less about understanding the physics of why the E-Cat device works than whether it produces heat or not.  Instinctively, I have had a positive opinion of the E-Cat since first hearing about the device in January, 2011.  After the March 2013 independent tests by accredited scientists obtained positive results, I have no doubt that it works, and that there has never been anything hidden under a deceptive sleeve.  Eventually, the world will understand the science behind the anomalous heat energy production of the E-Cat  device, but it seems that the only evidence that will allay skeptical criticism  is revelation of the secret catalyzing agent.  This undoubtedly has to be considered the intellectual property of Andrea Rossi and must be legally protected before divulgence.

I dislike the current Catch-22, and am openly impatient for the progression of what could be an immensely beneficial, clean energy technology for the good of the entire planet.

TEDxBologna – Sergio Focardi – L’E-cat e la fusione nucleare con il Nichel e l’Idrogeno

Uploaded by on Nov 7, 2011

Professore emerito del dipartimento di Fisica dell’Università di Bologna, ha contribuito alla costruzione della macchina E-Cat, macchina che produce energia elettrica con un processo fisico-chimico ancora sconosciuto.

Preside fino al 1990 della facoltà di scienze matematiche, fisiche e naturali dell’Alma Mater, ha poi diretto la sezione di Bologna dell’Istituto nazionale di fisica nucleare.
Ha concentrato i suoi studi scientifici sulla fusione fredda con reattori Nichel-Idrogeno ed ha collaborato con Andrea Rossi per la realizzazione dell’ E-Cat, un meccanismo per la fusione nucleare a freddo


The skeptical slant of the article does nothing but place doubt in the mind of the reader.  The E-cat has been repeatedly tested and verified by many physicists; including representatives of the Swedish Skeptics Society, Professor Emeritus Sergio Focardi of the university of Bologna and others.  While skepticism is necessary regarding such a profound discovery, there comes a point where the proof wins out over the armchair.  The E-cat is definitely NOT a hoax.  In fact, it is now commercially available.  Skeptics can buy one and test it all they want.  Clean energy has arrived!


Italian scientist claims he has achieved ‘cold fusion’ – the only problem is that most physicists think it is impossible (Daily Mail Online)

  • Andrea Rossi says he can fuse nickel and hydrogen at room temperature creating almost unlimited energy
  • Many scientists simply claim it defies the very laws of physics and cannot be true

True or false? Andrea Rossi says he has built a machine achieving 'cold fusion' but scientists question if it is possible

An Italian physicist claims he has managed to achieve ‘cold fusion’ – a procedure that could solve the world’s energy crisis by creating huge amounts of safe nuclear energy without dangerous radiation.

Andrea Rossi says his new machine fuses nickel and hydrogen at room temperature creating almost unlimited energy.

But there is one problem – many scientists claim it defies the very laws of physics. Several high-profile demonstrations of ‘cold fusion’ have been proven to be hoaxes in the past – and no one can adequately explain how or why it might work.

The United States Department of Energy the U.S. Patent Office say the process is impossible because physics rules out the possibility of room-temperature nuclear fusion.

But Rossi’s E-Cat machine can allegedly do it, and he says he proved it worked during tests at the University of Bologna last month.

‘With low energy, it’s possible to give a heater a certain amount of energy and to get from the same heater a superior amount of energy,’ he said.

‘The heat is initiated by electrical resistance. The reactors then produce another 479kWh of energy for another three to four hours without needing that initial electrical input — the low-level nuclear reaction continues on its own.

‘The test we made by the customer was to see if the process was working properly, and to control whether the energy was in an amount superior to the amount supplied to the system.

‘We have nothing to say, just to make plans that work properly and let those facts win against the scepticism.’

The idea of cold fusion was put forward by in the 1920s by Austrian scientists Friedrich Paneth and Kurt Peters.

But despite several people saying they have done it, it has been dismissed by most physicists.

An atom is a nucleus of protons and neutrons, with electrons orbiting around

Scientists say that Rossi’s claims must be taken from his lab and analysed before he can claim he has done it.

Energy consultant Jonathan Koomey said ‘[The E-Cat experiment] should be treated as a hoax until independent scientists are able to replicate these results,’

But Sterling Allan, CEO of the alternative energy news agency Pure Energy Systems, told he attended Rossi’s demonstration and the E-Cat is self sustaining.

‘What Rossi demonstrated was 470 kilowatts of continuous output in self-sustain mode — meaning the output was enough to keep the thing running on its own,’ he said.

UPDATED. Half a megawatt thermal power in self sustained mode, for over five hours. That’s what Andrea Rossi obtained with his E-cat plant on Friday, according to his customer. The question now is who the customer was.

(Swedish version here).

At about quarter past ten on Friday October 28, the test of Andrea Rossi’s heat plant, potentially producing one megawatt, was initiated in an industrial hangar in Bologna.

The plant consisted of more than 100 ‘energy catalyzers’ – Rossi’s invention that possibly produces heat from a hitherto unknown nuclear reaction – connected in parallel.

Already in January 2011 when the E-cat was demonstrated publicly for the first time before a group of invited scientists and journalists in Bologna, Rossi promised the launch of a one megawatt plant in October.

The test was supposed to be performed together with the Greek company Defkalion, and later, after a breach of contract in August, in the US.  Finally, as the US agreement was never put in place, the test was performed in Bologna under the control of a yet unknown customer to Rossi.

According to the customer’s controller, Domenico Fioravanti, the plant released 2,635 kWh during five and a half hours of self sustained mode, which is equivalent to an average power of 479 kilowatts – just under half the promised power of one megawatt.

Rossi explained this with the customer’s priority to achieve self sustained mode, which supposedly makes the process more difficult to control than when electrical power is supplied to support the reaction.

“We had to decrease the power during self sustained mode as the temperature rose too much”, Rossi said after the test.

Neither Ny Teknik nor any other of the guests had any possibility to check the measurements made. The invitees could only observe the plant in operation for a few brief moments.

Assuming that the report is correct (the report can be downloaded here, the temperature data here), a substantial amount of energy was released, which is difficult to explain by anything other than heat being developed inside the E-cat, even if you subtract the power input during pre-heating.

UPDATE: There are two minor errors in the report. See below.

According to the report the test was approved and the plant would now be transported to the customer where it supposedly will be part of an agreement on further tests in order to develop the technology.

It remains unclear who the customer is. Rossi has only indicated that it belongs to a particular category of organizations. One possibility is that it’s a military organization given that the title of the controller Fioravanti in the report is “colonel”, however, scored out with a pen.

Rossi stated that an agreed contract research at the University of Bologna can now be initiated and that discussions on collaboration with Uppsala University can get started.

There’s still no clear indication of when a test performed by independent experts can be done, although this is still what both readers of Ny Teknik and most experts Ny Teknik has spoken to demand.

UPDATE: David Roberson who made one of three analyses that Ny Teknik published last week on the October 6 test , has made an updated analysis here, which he claims contains proof that the E-cat generated a large amount of excess energy.
Also Horace Heffner’s analysis has been updated.

UPDATE 2: There are two minor errors in the customer’s report:
1. The weight of the hydrogen bottle should be in grams, not kg as indicated.
2. The indicated flow rate of the pumps at the end of the report should be 350 kg/hour, not 750 kg/hour, giving a total of 700 kg/h, not 1,500 kg/h, for the two pumps.
(The measured average flow rate of 675.6 l/h in the first part of the report should be correct).
