Re: [Vo]:Re: Regarding Rossi and NASA (+ some Piantelli news)
If you look at my text you will see I wrote "catastrophic failure" not just failure. This means an E-cat blows up spreading steam throughout the container, injuring anyone present, and preventing access to the container, causing the test to fail. I think I was clear on this point. I did not refer to anything bout an E-cat performance dropping. The other side of the coin to increased probability of some E-cat working when multiple devices run together is the increased probability of catastrophic failure.

It was the same reason Rossi has not gotten professional assistance. Experts offered to help, but the Wrights refused. As Harry Combs said, it was a "tragic" waste of their time. I know experts who have offered to help Rossi at no cost, with no strings attached. He has turned them down. Combs described the situation in 1907. It sounds familiar: "The potential contracts were battered and bruised but obstinacy on both sides -- the Wrights, and the men and groups with whom they were dealing. The brothers seemed unable to come to an agreement with anyone, and even as they stumbled from one collapsing deal to another in Europe, back in the United States, through the continuing interest and efforts of Samuel Cabot and his brother Godfrey, the capabilities of the rights flying machine were brought directly to the attention of President Theodore Roosevelt . . ." (Roosevelt's intervention is what finally turned the situation around.) Robert Goddard did the same thing, by the way. He spent years of his time and lots of Guggenheim's money trying to solve engineering problems that the people at the University of California could have easily solved. They told him they could. He ignored them. Actually, I think he blew them off, which is what Rossi has done. There is an important lesson in this. People here who think that Rossi is some sort of loser or fake because he acts strange or because he has a bad temper should read history. Read about Goddard, the Wrights, Edison, Harrison, Davy (and the way he treated Faraday), Oppenheimer's behavior in his rental house in the Virgin Islands, or Einstein's sex life. You will see that these people acted abominably. They were as flaky as Rossi is, or worse. You may suspect that Rossi is a thief and a double-dealer, but you can be sure that Edison was. You may suspect Rossi puts on a fake demos and hides the weaknesses of his device. Maybe he does, and maybe he does not. There is no question that Edison did that, often, with panache. You need to stop trying to judge this discovery based on the personality or morality of the discover. That never works. I could give dozens more examples. The converse is also true. Upstanding, honest, reliable, well-educated, highly recommended, top-notch mainstream scientists -- the kind of people who are appointed to important boards and high positions in academia -- often make stupid mistakes. In some cases during their entire career they do not come up with a single important breakthrough. Any number of such people have made idiotic assertions about cold fusion. In 1907 dozens of them made similar idiotic assertions that airplanes cannot exist. In 1879 many of them went on record in major journals and top newspapers asserting that Edison could not possibly have a subdivided incandescent light -- such a thing is inherently impossible. (No expert disputed that incandescent lights are possible. They had been demonstrated for 20 years.) These were considered the top experts. They thought they were experts. Actually, they had no idea what they were talking about, but the journals and newspapers thought they did, just as nowadays reporters think that Robert Park knows something about cold fusion. - Jed

On the other hand, we don't know much about this form of fusion (or Mills' effect, or zero-point energy, or whatever it is), and no one has ever produced it on such a large scale, so that also should be a concern.

I know several experts in heaters who say that the reactor is poorly designed. They say that even if the individual reactors were fake with electric heaters in them it would be dangerous. Heavy equipment of any type is inherently dangerous, even when it is designed and operated by experts. Even when it has been run for decades. Marine engines sometimes catch on fire and kill people -- that happened a few weeks ago. Nuclear reactors at Three Mile Island, Fukushima and elsewhere have gone out of control and self-destructed. Billions of automobile engines have been manufactured and they are among the most reliable machines ever made, but when one of them leaks fuel or goes out of control it can easily kill you. - Jed

There is NO evidence that Rossi's newer generation E-Cats have ever or will ever explode. Rossi has maintained that in the event that they melt down that they simply stop producing heat. If you happen to be on Rossi's invitation to see his 1MW plant, by all means take whatever precautions you like to keep safe. But to suggest Rossi is an idiot who might kill the "top scientists" witnessing his invention is just plain silly. Pressure gauges are a few dollars, and I'm guessing Rossi knows how to use one. He might even employ a burst disk or pressure relief valve! Some of you believe there is no reaction, others believe that the reaction is wildly unstable. Rossi says there is a reaction and he can extract at least 6x COE. Seems like we need a good parimutuel betting website where we can put our money next to our opinions. Peace. - Brad

Some experts have told me they feel this reactor as configured is very dangerous. I see no point whatever to running it. Ed Storms suggested to me that Rossi may be having some difficulty coordinating individual reactors to make them work together as a group, and that his purpose is to show that he can do this. If Storms is right, and coordinating them is challenging, I think Rossi should leave this job to someone else. I am certain that experts at corporations such as Mitsubishi or General Electric can solve this problem. No matter how difficult it may be, it is trivial compared to the original problem of inventing the reactor. It is absurd for Rossi to spend his time solving a problem like this, because this is "merely a matter of engineering" -- meaning many other experts in the world can solve this.

Hi, Oeps, the commas must be periods so this should of course be red as: Me thinks you are wrong. Your statistical probability calculation is based upon the fact that the chance of a single Ecat exploding is influenced by it's behaviour earlier, which of course is not true. Statistically each Ecat has it's own independent chance of explosion at any given moment which does not change over time. With your probability of 0.1% chance per hour this would result for the whole of 52 Ecats then in a chance of explosion at any given moment of 1 - (0.999^52) = .05 or 5%. Looking even a bit more closer again this would mean that if the chance of explosion is 0.1% per hour then the chance of explosion is 2.77e-7 per second at any given moment for a single Ecat, which would result for 52 Ecats into 1-((2.77e-7)^52) = 0.134 or 0.00144% at any time. Kind regards, MoB

WE WILL MEASURE THE ENERGY TAKING THE DELTA T OF THE WATER, THE WATER, THE WATER, NOT OF THE STEAM NOT OF THE STEAM, NOT OF THE STEAM, THEREFORE THE ISSUE OF THE QUALITY OF THE STEAM HAS ABSOLUTELY NOT IMPORTANCE, BECAURE WE DO NOT MEASURE THE ENERGY FROM THE STEAM !!! WE COULD PUT IN THE PRIMARY CIRCUIT STEAM, DIATHERMIC OIL, GLYCOLE, COCA COLA: IT IS ABSOLUTELY IRRILEVANT WHICH IS THE FLUID IN THE PRIMARY CIRCUIT AS FOR CONCERNS THE MEASUREMENT OF THE ENERGY BECAUSE WE MEASURE THE ENERGY ONLY MULTIPLYING THE CUBIC METERS OF WATER FLOWING THROUGH THE SECONDARY CIRCUIT BY THE DELTA t OBTAINED SUBTRACTING FROM THE TEMPERATURE OF THE WATER (LIQUID) OF THE SECONDARY CIRCUIT AT THE EXIT FROM THE HEAT EXCHANGER THE TEMPERATURE OF THE SAME LIQUID WATER AT THE INPUT OF THE SAME HEAT EXCHANGER.

The fact it is more difficult to manually monitor 53 E-cats than a single E-cat also means the probability a single E-cat of the 53 blows up in a given hour would be higher than it would be for that E- cat operated singly. It is not even clear facilities to monitor individual critical E-cat conditions, like internal pressure or flow, are present in the 1 MW E-cat. If no individual monitoring is feasible then the probability of individual failure in a given hour should be much larger than when independently operated. Then there is the feasibility of the 1 MW unit producing over a MW just from the huge thermal mass it has, even if all nuclear reactions are shut down. A significant back pressure due to the seam vent pipe being too small could reduce input water flow resulting in suddenly increased boil off of the water in the E-cats resulting in a catastrophic feedback loop and multiple E-cat explosion. The individual probabilities of failure can be made larger in a combined configuration due to additional shared parts. Best regards, Horace Heffner http://www.mtaonline.net/~hheffner/

Robert, Rossi made 58 of “difficult to keep stable” modules and put together. If reaction is so instable, nobody will made a central. I think that the end of the hoax is approaching. From: Robert Leguillon Sent: Wednesday, September 28, 2011 9:11 PM To: vortex-l@eskimo.com Subject: RE: [Vo]:Regarding Rossi and NASA (+ some Piantelli news) My two cents: As was previously theorized, Rossi may have really been onto something. Unfortunately, when the reaction occurs, it is difficult to keep stable; it runs away and needs to be quenched. If you recall, the Defkalion rumors centered around a nonpayment from Defkalion until Rossi achieved stability. In an effort to "tame the cat", and "make it safe" he had tried to find a lower-power stable setup. But, he only really achieved stability when it WASN'T WORKING. By failing to do proper calorimetry and use proper controls, he'd fooled himself into thinking it's running smoothly when it isn't running at all. If Krivit's sources are correct (it is worth reading the entire NET article), NASA really sounds quite excited about LENR, and appears to have made great strides in successful replication. I just wish that they would publish their results openly. They successfully saw anomalous heat in 1989, but were afraid to admit it, until now: ""Tests conducted at NASA Glenn Research Center in 1989 and elsewhere consistently showed evidence of anomalous heat during loading and unloading deuterium into bulk palladium. At one time called “cold fusion,” now called “low-energy nuclear reactions” (LENR), such effects are now published in peer-reviewed journals and are gaining attention and mainstream respectability. The instrumentation expertise of NASA GRC is applied to improve the diagnostics for investigating the anomalous heat in LENR."" http://www.grc.nasa.gov/WWW/sensors/PhySen/research.htm But, Krivit may be onto something. The NASA site I've linked above has the following soon-to-be-link at the bottom. + Download presentation given at a LENR Workshop at NASA GRC in 2011 [available soon]. LENR looks to really be gaining attention. Andrea Rossi may be lost to history, if only by his own behavior.
