no excess heat in June 14 Rossi demo, as no invisible dry steam at end of hose, just feeble mist, perhaps liquid water -- many unbiased critical comments on Vortex-L: Rich Murray 2011.06.25 http://rmforall.blogspot.com/2011_06_01_archive.htm Saturday, June 25, 2011 [at end of each long page, click on Older Posts] http://groups.yahoo.com/group/astrodeep/message/86 [you may have to Copy and Paste URLs into your browser] ______________________________________________
I've suggested Rossi, searching blindly the last 2-3 years for a way to prevent thermal runaway, has stumbled into using an input electric power that vaporizes some of the water flow, without initiating any nuclear reactions, while managing to believe that the output mist is "visible steam", as he clearly stated at the end of the 13:24 minute video demo by Steven Krivit June 14, 2011... After 11:00 minutes, Rossi lifts up the last 1 m of the 3 m black water outlet hose, then drains water from the end of the hose into the blue bucket, then shows the end of the hose against a black sweater -- clearly the white mist slowly coming directly from the end of the hose is not steam, which is invisible, but water mist. This proves that very little steam must be coming out of the reactor at the start of the 3 m hose. Both water and water mist are flowing at 7 liters per hour, 1.94 cubic centimeter per second [ 7/3600 = .001.94 liters per second ]. If all the water was turned into steam, that would be 1.94X1700 = 3300 cc per second of steam, 3.3 liters per second from a hose with an inside diameter of about 2 cm. http://www.youtube.com/watch?v=m-8QdVwY98E 13:24 minutes June 14, 2011 2011 - Andrea Rossi Explains His Energy Catalyzer Uploaded by StevenKrivit on Jun 20, 2011 Link to New Energy Times reports: http://tinyurl.com/4362kl9 "Steam": 11:30 [ mist emerging feebly directly from 3 m black hose after 11:00 minutes... ] https://mail.google.com/mail/u/0/?shva=1#inbox/130c0c7a4f3af693 10:45 minutes June 14, 2011 2011 - Andrea Rossi Crunches the Numbers for His Energy Catalyzer Uploaded by StevenKrivit on Jun 23, 2011 Link to New Energy Times reports: http://tinyurl.com/4362kl9 https://mail.google.com/mail/u/0/?hl=en&shva=1#sent/130af02b8ad0f43e from Rich Murray [email protected] to [email protected] date Mon, Jun 20, 2011 at 7:01 PM subject Re: [Vo]:[Video] Andrea Rossi Explains His Energy Catalyzer (NET - June 14, 2011) Jun 20 (5 days ago) I agree the gas flow out the end of the black hose seems to be visible right at the end -- whereas steam would be invisible for a short distance. Trained as a dishwasher since age 10, 80 miles E of Houston, Texas, I am sure that hot water gives off mist in low altitude, warm, humid climates. Rossi seems to be saying that "cool" steam is slightly visible as a mist, while "hot" steam is invisible! All steam is invisible, by definition. Rossi seems to me to be natural, relaxed, matter of fact, genuine. Isn't it possible for the pump to fill the reactor up totally with water, which would then overflow and exit as water just below boiling, or water exactly at boiling, mixed with variable amounts of steam? Would any bubbling at the outlet of the reactor be audible? How noisy is the background? Since about 1 m of the hose lies on the floor, before rising about1.5 m to pass through a hole in the wall, wouldn't that part of the hose on the floor fill up completely with water, with a flow of 7 kg/hour? How much pressure results from the 1.5 m rise in the hole? Also the hose on the floor, if full to 1.5 m, would be equally full on both arms of its "U" bend... If so, then would that ensure that all steam is condensed while passing through a full "U" bend? How much output heat is there if very little of the water is boiled within the reactor? My guess is that the Rossi team actually don't have a clue about what is happening between the device outlet and the far end of the hose. https://mail.google.com/mail/u/0/?hl=en&shva=1#sent/130b2661426493fb from Rich Murray [email protected] to [email protected] date Wed, Jun 22, 2011 at 9:52 PM subject Re: [Vo]:E-Cat proven to be a hoax? Jun 22 (3 days ago) Well, maybe Rossi has spent 2 or 3 years with a setup that really generates gross excess heat energy from LENR, but is explosively unstable -- as the temperature is raised to the level that initiates LENR, the resulting gross nuclear energy release, naturally, immediately rises so steeply as to overwhelm such control parameters as H2 pressure, H2O flow, heat input from electric heater -- finally, he finds a setup that generates 6 to 12 times more energy than input heat, BUT -- 1. he started assuming complete boiling of the water flow into dry steam, whereas actually only a small fraction of the water is ever boiled in his stable runs, so that, 2. the claimed output heat is exaggerated by 6 to 12 times input electric heater power, 3. and, highly motivated to finally have a complete success as an inventor who contributes hugely to humanity and gains praise and wealth and opportunity to continue inventing on a grand scale, he very humanly falls into unconscious habitual resistance about actually double checking the reality of completely dry steam output flow, 4. so that close associates fall into this unconscious blindness, evolving a resiliant group think dynamic that presents a series of confusing demos that finally draw enough scrutiny for the possibility of the error to be discussed by many, 5. whereupon Rossi, a good, honest and forthright man, will quickly do a simple check, verify the error, and share the discovery immediately and openly, 6. and, since he lacks the expertise and resources to engineer how to stabilize the reaction (even if he understands it correctly...), he also immediately discloses every detail of the setup, so that the world as a whole can properly explore this crucial breakthrough for the benefit of all. from Joshua Cude [email protected] reply-to [email protected] to [email protected] date Fri, Jun 24, 2011 at 10:27 AM subject Re: [Vo]:Rossi calorimetry, volume vs mass, etc. Jun 24 (1 day ago) On Fri, Jun 24, 2011 at 10:33 AM, Daniel Rocha <[email protected]> wrote: *Just to be sure of my position. I am completely convinced that the data that has been provided is coherent with a power generation of 2.5KW. But the presented data is also consistent with power equal to the input electrical power of 800W. That's Rossi's con. If he restricts the data to temperatures, and input flow rate, and brings the flowing water to a boil, the same data can represent output power over a 7-fold range. He of course claims the high end of that. And until Krivit, he was not directly challenged. Even Krivit's challenge (so far) is pretty mild.

But this assumes that any liquid hot water needed to cool water vapor in a heat exchanger is included in the calculation (otherwise the ratio would be worse, less than 1.86 to 1). I did this calculation, shown below, weeks ago. Basically in this fraudulent set up, the Ecat would do the following: 1. Create 1 kg of 99.9 C water from 10 C water which requires (99.9 - 10) x 4.18 kJ/kg/C = 376 kJ 2. Using same water from step 1, make 1 kg of water *vapor* requiring 2257 kJ. Total input to Ecat required at this point is 376 + 2257 = 2633 kJ 3. Condense water vapor into micro droplets (i.e. fog) deep *inside* the Ecat using a heat exchanger and use this heat to heat 6.00 kg of cold liquid water from 10 C to 99.9 C. This is because 2257 kJ /376 kJ/kg = 6.00 kg (note that the units are correct). Also, note that at this point the total input energy is still 2633 kJ. The actual/real end result is 6.00 kg of 99.9 C water and 1 kg of micro liquid water *droplets* (fog or steam with 0% quality). A gullible observer would think that the Ecat just produced 6 kg of hot water and 1 kg of water *vapor* when it really made 6 kg of hot water and 1 kg of hot *liquid* water droplets. The gullible observer would think that the energy normally needed to create this is 4890 kJ because: (6 kg + 1 kg) x (99.9 - 10) x 4.18 kJ/kg + (1 kg) x 2257 kJ/kg = 4890 kJ While in *reality* it took the following amount of electrical energy: (6 kg + 1 kg) x (99.9 -10) x 4.18 kJ/kg = 2633 kJ So, the gullible observer would see 2633 kJ of electrical energy go into the Ecat and 4890 kJ of thermal energy leave the Ecat. This is a ratio of 4890/2633 = 1.86 I can't think of any way of increasing this ratio using any other similar method.

Different thing. And it's easy. The power can range within a >factor of 7. In this case, anywhere between 600W and about 5 kW. BTW (the latent heat of steam) / (the heat energy required to bring water to the boil) is a factor of about 6.7 (depending on starting temperature of water), and curiously close to the COP Rossi claims to be aiming for. In short, if virtually none of the water were converted to steam, and he was assuming that it all was, then it would neatly explain the conversion factor he is claiming.

If he can do that, he has truly mastered cold fusion! Jed, man, think about that -- don't just jerk your knee at me in an automatic defense of Rossi, really think about it. Rossi has a factor of SEVEN in output level in the range he has to hit in order to produce SOME steam and SOME hot water, and you have just said it would be hard for him to control the anomalous heat well enough to do that. But Rossi's claiming to have produced exactly enough heat to EXACTLY vaporize all the input water, and NOT HEAT THE STEAM beyond boiling --- that target is orders of magnitude smaller than the target he'd need to hit to produce some steam and some hot water! If he overshoots his "dry steam" power level by even a little, the steam temperature will go up by a lot; the specific heat of steam is very small compared to the heat of vaporization of water. But the temperature never rises more than about a degree over boiling! Jed, the point you just made is the point that's been bugging me all along -- it would take a miracle of fine control to generate EXACTLY enough anomalous heat to EXACTLY vaporize all the input water, without superheating the steam, and without leaving wet steam or having the device spit water! There's no evidence of that degree of control, no evidence of a feedback loop which could be providing it, no reason except wishful thinking to believe such control exists ... so the conclusion is that he's actually got the power level set somewhere within the "factor of 7" window, and he's producing very wet steam or a mix of steam and liquid water; he does *NOT* have it "right on the edge", producing dry steam just over the boiling point. It's absurd to think he could exercise the level of precise control needed to produce "exactly dry steam". (And that about uses up my Friday night send-some-useless-email time...)
