Gauge all you like, I'm not claiming any credentials. But I don't have to be an engineer to look up tables proving you are wrong. That pipe must be at least 3" or 80mm?
You can read the pipe size from the photo, the end cap says 2 1/2 inches.
2.5 in = 63.5 millimeters
Dear sir,
you are free to think what ever you want but there are plenty of proofs that the ECAT works. There is also a good theory candidate already published from years. (Widom, Larsen, Shrivastava)
If somebody thinks that is a hoax, that's not my problem.
Best Regards,
G.L.

Although it has been a while since I graduated with physics, Im very skeptical about this until other scientists replicate and duplicate this in the laboratory under controlled conditions with peer reviewed articles.

I am not going to get my underwear in a bunch until this happens. Peer review is important in science, because it weeds out the snake oil salesmen from the true new breakthroughs in science.
If it is duplicated by other scientists, and found to be as advertised, well I'll be the first to shake the man's hand and say well done. Until then, no.

Thanks for posting.
I do not wish to get into any thermodynamics / fluid mechanics tutorial here.
Besides that is not a bloomin 80 mm pipe. The ID I estimate is not more than 30 mm.
Now screw the whole set up. Is there any known figure of how much condensed water
was collected from the steam oulet of the HE and at what temp.

I don't know if you are trolling (I suspect you are trolling since you have quickly dropped your supposed proof of functional impossibility), or genuinely don't know the difference between a 30mm pipe and a 3 inch pipe. But I will demonstrate:
2600mm divided by 31 = 83mm
So, yes, that is almost certainly the kind of pipe you'd want use to transfer 675 kg of 115c steam an hour at 1 bar . It is a ~80mm pipe.
To hammer the point home, here are the heatsinks at the end of the steam pipe:

Andrea Rossi ,....
You are right, we are organizing this. BY THE WAY: WE COLLECT FROM NOW THE NAMES OF ALL THE PERSONS OR ENITITES INTERESTED TO BUY AN E-CAT OF 10 KW. IF WE WILL REACH 10,000 NAMES IN THE LIST, THE PERSONS IN THE WAITING LIST WILL HAVE THE RIGHT TO CONFIRM OR NOT THEIR ORDER AT 400 EURO/THERMAL KW. DO NOT SEND MONEY, WE WILL ACCEPT THE ORDERS ONLY IF WE WILL REACH 10,000 NAMES IN THE WAITING LIST, COMBINING OUR LIST WITH THE WAITING LIST ORGANIZED BY OUR BROTHERS OF HYDROFUSION .

The OD of the thread on the cap of the oversize stop valve is 21/2 in.
So , so much for your 83 mm pipe, the less said the better.
"What doesnt add up is also the size of the insulated steam pipes and the size of atmospheric condensers. I dont see rhem carrying steam worth 20 kw let alone 479 kw."
Now once again how much condensed water was collected, from the steam outlet of
the condenser?
If this figure is not known, then sorry it doenst convince me of anything except that if he
has got a COP greater than unity, in the stand alone mode, he has still acheived something.

Okie, it is a ~60 mm pipe then. Twice your expert estimate. You could fit twice as many 30 mm pipes on that container.
You've made that point a couple of times, but now you're just dropping it? It would be a good proof of impossibility if you could back it up with numbers. If you could show us a calculation and estimates to prove it is not possible, that would be helpful. Remember there are two of those condensers.
Surely you already know how much water was supposedly evaporated and how much was collected as unevaporated water if you have read the report?
675 litres vapourised an hour, then recondensed, and then pumped back into the large tanks. 5 litres collected as unevaporated water. It was a closed system with some minor topping-up of the large tanks to account for loss.
This might picture the unevaporated water container, connected to the steam pipe?:
The average temp for the steam is given as 104.5c, not 115c as I have stated before. The max was 112c.
Could you properly elaborate where and why you think these measurements are flawed, or not good indicators of energy production? It seems to me that making 675 kg of 105c steam travel several meters away from the boilers is a pretty robust energy measurement.

Wrong again. For your kind info pipe sizes are quoted by the internal bore.
so my estimate stands. The stop valve is oversize. The bore of the valve by my estimate is 40 mm.
So its a 40 mm valve.
Temp is not an indicator if not accompanied by mass flow and the mass flow is vastly exaggerated.
Anyway you seem to be connected in some way with rossis commercial aspirations and i wish you luck

I am in no way connected to Rossi. I had never heard of him until a few weeks ago. It would be nice to be able to invest in something like the E-cat, but unfortunately I can barely afford the electricity bills I have to pay right now.
Rossi is not the reason why I believe in the viability of this device, I believe it is possible because I have actually bothered to read about the electromagnetic properties of nanoparticles.
Sorry to labour the point here - I am not claiming I know anything about pipes, since the most I've ever done is replace a water pump on my central heating. But you are now suggesting that the blue pipe internal diameter is 40mm (up from the previous 30mm), and it has a casing 10+mm thick?
As I said, I have never done pipe calculations before, but I would imagine you have already realised this should be factored - what would the pressure be in a 60mm pipe if it is fed with 52 steam inputs from the reactors, if they are outputting approx 13kg/h of steam? How does that affect the potential flow rate?
The amount of water that went through the external tanks was measured. I assume the flow rate would be the critical measurement for any buyer. The amount of water going in and coming out was supposedly 675kg/h. A water flow rate sensor would tell you this, it is a trivial measurement.

Moreover the glaring flaw is factoring in the heat recovery from steam in the condenser.
The whole show is most likely a scam.

Here it is again, this killer punch which you will not spend five minutes explaining. I think we can handle it?
Perhaps you are too absorbed in the quantum physics of tomatoes and Billy Graham?
It is funny you are calling this man a fraud the day after he visited government officials at State House in Boston to talk about his device. A meeting also attended by representatives of Massachusetts Institute of Technology and the University of Massachusetts and Northeastern University.
He seems to be much better at fraud than those claiming to have found 'zero point energy' and having overthrown general relativity in the process. I'd say, a different class of fraud altogether.
Mr. Rossi’s reactor, if successfully proven and developed, has the potential to change the way the world deals with energy, and I’m pleased that he’s willing to discuss basing its production in Massachusetts."
Andrea Rossi says Defkalion will not have a working model until it can "procure" one of Rossi's to reverse engineer or use hidden inside one of their mock-ups to simulate a working device. Makes me wonder, what will the Defkalion people reveal in two weeks?
Andrea Rossi Quote,
Look to what is going on around the Balcans: there are clowns saying they have a technology copied from us, actually they have just a moke up, waiting for the piece of info they need to make a real copy. They believed we would have been selling in October the small E-Cats, so announced they would have made a demo in october ( buying a model, disguising it as a copy made by them). But it was just a trap we made. Conclusion: from now on we will be more sealed than ever, and we will be open exclusively with our Customers.

Can you stop filling every page of this informative and progressing thread with dozens of meaningless repetitions of 'I THINK THIS IS A FAKE!'. We understand that you think it's a fake. You are adding nothing.
This topic will remain interesting until it is properly debunked, and it will never be debunked by people behaving as you are.
A point about the reality of this customer or not: according to Rossi - the initial purchase of this reactor/s is paying for two years of proper, to-be-published research into the e-cat at the University of Bologna. Wouldn't the whole thing unravel very quickly if he is not able to fund the university? Do you not think the invested academics might publicly raise this issue asap to protect their reputation?

I'd imagine he means all those academics that turned up to one display or another from Swedish Universities or the Italian academics involved.
I'm sure there are other prestigious academic people who have been present at one demo or another, and none of them (to my knowledge) are screaming about fraud...which isn't proof of anything i know, but at least it is evidence they have not detected a fraud.
In fact, these guys were present:
Hanno Essen, a theoretical physicist at the Swedish Royal Institute of Technology and chairman of the Swedish Skeptics Society, and Sven Kullander of Uppsala University, chairman of the Royal Swedish Academy of Sciences Energy Committee.
Essen and Kullander gave the E-Cat a solid thumbs-up. It produced too much excess heat to have been originating from a chemical process, they wrote in their report, adding that, "The only alternative explanation is that there is some kind of a nuclear process that gives rise to the measured energy production."
And another from MIT:
"Basically, there's a new physical effect that I think was found in the lab more than 20 years ago by Fleischmann and Pons [University of Utah electrochemists who were later derided for their work on cold fusion]," said Peter Hagelstein, an MIT professor of electrical engineering and computer science and one of the most mainstream proponents of cold fusion research.
"It was not accepted by the scientific community. It's been laughed at and criticized. However, over the years the effect has continued to be seen."

And this guy too (from NASA no less, or CIA)
Dennis M. Bushnell, Chief Scientist at NASA Langley Research Center, described LENR as a "promising" technology and praised the work of Rossi and Focardi.

These are just a few. Admittedly they were not allowed to inspect the device closely, so is still up in the air of course, but even so, they are not crying foul about it.
