Re: [Vo]:I.H. press release responding to Rossi
*De-lurks* Ridiculous to assert that IH have not acting in good faith - if the demo worked they would be the happiest people in the world and would be on track to make vast amounts of money even if they had to hand over 90million they would be doing so with a big smile on their face. The very simple truth is that Rossi has made big claims and has (as usual) failed to deliver. Almost certainly IH will have their hands tied due to confidentiality agreements, so will be prevented from revealing in detail just how bad/unconvincing things are and how ridiculous Rossi's usual dissembling shenanigans have been. Looking back through all his demos he has never done one that has unequivocally proven that it works - always potential errors greater than claimed outputs. I note also that attempted replications by those using high standards of practice like MFMP have not managed to get LENR unequivocally working - accepting that reality and yet believing that Rossi has through incredible luck and bad experimental practices succeeded with different configurations, different temperature regimes and different ignition methods and approaches with massive power outputs and high COPs where all others have failed is several bridges too far in the level of credulity required. I am no longer willing to give Rossi the benefit of the doubt - he is transparently just playing for time and more money, and with his track record you would need to be a mug or the king of wishful thinking to keep believing in him. The only vague question left in my mind is whether he truly believes he has cracked the LENR nut. I could be convinced that he does, and is fooling himself, but think it most likely he does not given how long his circus has been going on.

Re: [Vo]:Jiang reports successful Lugano replication
I skimmed through it, one thing that struck me was that they hit 1372°C for 10 minutes. I have serious doubts that their stainless steel vessel could have survived such a temperature (barely bellow melting) - which makes me suspicious of an error somewhere, this is above where k-type thermocouples would typically be expected to be accurate or reliable. Also melting point depression would have melted nickel powder at such temps destroying (what I thought was important) nickel surface morphology. They seem to have good resources so hoping they do better calorimetry in future.

*delurks* Frustrating that with COP's 2 and output powers of 100's to 1000's of watts that simple calorimetry cannot be used to remove doubt, instead we have 5-10 equivocal demonstrations from Rossi over last 4 years, (supposedly a genius, yet not competent or willing to do this relatively minor part right, and endless excuses and supporter rationalisations about why he doesn't need to do it well - which stink). Still awaiting combined big COP+bullet proof calorimetry from newer replications. At these outputs simple 20% error flow calorimetry setup is probably only $1-200 in parts and 1-2 days in build time (aquarium pump, couple of buckets and thermocouples). Might it be that when better calorimetry is applied good news disappears (eg MFMP)? In which case sloppier calorimetry would be more rewarding and get more traction given the illusion of success. I've given up on Rossi (Lugano sunk him in my eyes), and my hope for others will probably not last into 2016 without some good results.

Re: [Vo]:temperature of the resistor wire.
(Dave, my granddad is Bob, I'm Robert :) ), I would be over the moon if we had incontrovertible evidence of COP, but with a strong grounding in and respect for the scientific method you cannot and should not ever give bold assertions a free ride without vigorous critical review the skeptics of the world won't go any easier on him than I will. Which is what I am trying to provide, and unfortunately the harder I have looked at it and the more issues I have analysed the more likely it seems that the gain = 1 hypothesis is as strong as gain 1. Occams razor would then favour gain=1 rather than a collection of miraculously fortuitous LENR characteristics that include numerous transmutation pathways (fission and fusion of Ni and Li) without ionising radiation, or change in reaction rate as it goes from natural isotope ratios to essentially all Li6+Ni2, But my suspicions really shot through the roof after reading that Rossi bought 99% Ni62 from a commercial supplier at one point - and that is why I decided to look so hard at the physical attributes of the device (thermodynamics/hightemp materials are my forte) - to see whether it was thermodynamically unabiguous that there was gain 1. The needless ambiguity of the test raises my ire, that the power input is so clumsily measured when it would be so easy to use series resistors, triac switched single phase AC, PWM DC power supply or etc with the same electromagnetic effects within the reactor. Rossi with his resources could get someone to make such an unambiguous power supply/meter in a day - but as usual he has chosen the dark path of deliberate obfuscation. Likewise with the lack of thermocouples or proper flow calorimetry - so easy when the COP and power output are large. But back to the physical problems: -The major red flag is that of inconel heating wire temp being necessarily 1300-1350°C (and realistically probably lower) while thermography is claiming 1412°C surface temps screams out that there is a massive error in the calorimetry, rendering the claims of gain meaningless unless or until that error can be explained satisfactorily. Hopeful theories about refractories wires etc just don't stand up to practical considerations (joining them to inconel that will anyway be melted at joint, forming these horribly brittle materials, keeping them away from air). -Knowing that the alumina is translucent also opens up so many possibilities for errors - and the translucence is unknown and unquantified for the material used over the range of temperatures and for the range of wavelengths of emitted light created by hot embedded wires - claims of it not being a problem don't hold water due to the above demonstrated/known error in the reactor temperature. We have no idea how much porosity it has, how thin it is, or what surface impurities might accumulate during long term high temperature operation to alter emissivity/translucence etc. -That I have identified a likely construction for the reactor that gives the visual results seen during testing (glowing wires wrapped around inner tube, but with minimal and variable contact quenching bought on by differential thermal expansion), all encased in outer shell), with no reactor gain only increases the strength of the gain=0 hypothesis. This could all be fixed easily by Rossi releasing more details of construction - even photos of cut-open reactor or just doing a proper independent black box test with good calorimetry. But as ever he is playing games due to paranoia, perverseness or worse motives.

I wonder about whether or not the actual temperature is correct as well, but am in no position to prove one way or the other. The most important observation that supports the elevated COP is the slope of output power versus input power that they measure about their chosen operating point. I can think of no way to fake that measurement without a dose of true magic.

Re: [Vo]:temperature of the resistor wire.
Well I can argue that there is no excess heat - The thermography is proven to be wrong (inconel resistance wires melt at 1300-1350°C 1412°C surface reactor temp claimed, and wires would have to be much hotter than reactor surface). If there is little to no conductive contact between non-melting wires and outer shell then the outer shell is only around 1000°C and there is no excess heat - a sensible physical model given what we can see in photos, with cameras perhaps 'seeing' or being badly skewed by the radiative output+ different emissivity of the wires rather than the translucent alumina of unknown thickness, porosity and transmissivity in the wavelengths of interest. So with the thermography proven to be massively in error how do you know there was any excess heat? (There is also problems with the convective heat transfer, due to sitting above a hot surface though they are smaller in impact, just as radiative heat transfer might be slightly impacted by hot frame underneath but probably also minor).

Most likely means of construction is winding wires around an inner tube, or winding them around a different mandrel and then slipping them over the tube. Bonding them to the inner tube is an extra step that (based on inconsistency/variability of surface glow) has likely not been done and for which their would be little initial motive anyway. And massive relative thermal expansion of the wire (~1%) would likely have cracked any ceramic bonding or attempts to rigidly encase the wires or bond them to the inner tube anyway. Differential thermal expansion means that the internal tube/vessel is likely only bonded to the thermocouple end cap, otherwise the external tube would be broken by axial stress due to differential thermal expansion of higher temperature of inner tube compared to external tube.

Re: [Vo]:Engineering and materials issues with high temperature hot-cat Lugano demo
If the LENR reaction suffers from thermal runaway then the best means for cooling is a coolant fluid slightly below the target temperature. Eg 1180°C coolant and 1200°C running temp so raising temp to 1240°C would then triple cooling rate, so 'clamping' the temperature. A lithium heat pipe would do this really well - vent at a controlled pressure to control the temp. The heater wires provide a crude and inefficient version of this for control purposes. If an oscillating magnetic field is required for excitation then that can be provided more efficiently without massive resistive losses. At 1200-1400°C a gas turbine would be ideal - with about 45% efficiency possible in compact device with no cooling water. Or 55+% with steam bottoming or CO2 or Helium recuperated Gas Turbine that are much more expensive.

Re: [Vo]:temperature of the resistor wire.
All fair points of view Dave. Though with regard to 3 phase, at 900W input there is obviously no need, adds a lot of mechanical complexity (3 heater wires rather than 1) and a little more electrical complexity and would still get impulsive waveform using rectified DC + half H bridge to provide an ac pwm output - really simple linear power control that is dead simple to measure and control power output of, with much greater scope for variation of pulse frequency and duration. I doubt you or any other engineer or electrician would choose to do it the crude and restrictive way he has. Haven't tackled the electrical side of things much; but as an EE would you agree that conceptually it would be possible to hide a 10kHz AC signal superimposed on the grid supplied 3phase with amplitude a little less than the AC so as not to trigger the Triac turn off? (Hardware pretty simple, just 50% duty cycle driven half-H bridge of phase added to the 50Hz signal by means of a series transformer). My rough calculation suggest that could allow 3x the power to be delivered to the reactor without showing up on the PCE meter or having any DC component. Not that I think it likely (far too much potential for getting caught by someone with a multimeter or oscilloscope), but if the power meters were known to have a max frequency threshold then could this allow you to deliver more power without it being easily spotted?

Re: [Vo]:temperature of the resistor wire.
But the wire cannot be tungsten outside of the reactor where it is exposed to air! Only inconel will survive air exposure at such temperatures for a month, and it maxes out at about 1300-1350°C (even that is pushing it). And that wire (Fig 12b) is visibly brighter than the wire lines in the reactor (or brightest surface areas of reactor), hence hotter. So QED the reactor surface is 1400°C. The thermography is flat out wrong for reasons unknown, and knowing that it is wrong you have to set aside all the conclusions that are based on it! The wire in the reactor in an insulated environment is necessarily hotter than the wire outside the reactor, and while everyone might want to believe that they must therefore be using exotic refractory wires that cannot be the case: There is no way to joining the inconel wire to a refractory metal at a temperature above the melting point of inconel within the insulated and even higher temperature of an oxygen-free sealed environment within the reactor. The only conclusion that makes sense is that the wires in the reactor are at or below the melting temperature of inconel, and in such circumstances the only way that they do not melt and fail is if the reactor surface temperature is at least 2-300°C lower as I have previously shown. As to growing belief in gain, I started out that way, but more I have looked at the thermal physics in play and the inconsistencies it creates the less believable it has become, the pictures and heat transfer physics at play make it a strong possibility that there was no gain.

Re: [Vo]:temperature of the resistor wire.
the resistor wire expands with respect to the alumina as it heats up, breaking any bonding contact, or lifting the wire of the inner alumina tube in more and more places and leading to less and less conductive contact - prompting the wire to heat up as more as more of the energy it transmits to the reactor must be via radiation and conduction through gas rather than contact-conduction.

Re: [Vo]:temperature of the resistor wire.
It has nothing to do with measuring of the wire power, except that as the wire heats up, increase the thermal resistance of the heat flow between wire and reactor body (by reducing number of points of physical contact) and of course the wire temperature will go up (given same input power) - I suggest you think a bit longer about it.

Re: [Vo]:temperature of the resistor wire.
So how do you imagine it inductively heats the powder given low AC frequency, weak solenoid magnetic field, tiny cross section area powder, and high resistivity of nickel near its melting point? The physics + mathematics to estimate the magnetic field strength and eddy currents induced are high-school /freshman physics level (estimate wire turns, solenoid inductance = applied voltage gives current rate of change, = solenoid magnetic field strength rate of change = eddy currents induced in particles of given diameter - power dissipation, so you could very quickly do some calculation to confirm or disprove your theory, and numbers would at least give foundation to your hope.

Re: [Vo]:temperature of the resistor wire.
Not if it is touching the walls of inner or outer alumina tube in places, intermittent contact due to vagaries of original wire winding around inner tube and subsequent large differential thermal expansion so that the wire is quenched in some places but not in others. Would explain the variation in glow that we see (along with slight translucence of alumina tube), and would change as the wire gets hotter and relaxes pre-existing springiness that might otherwise hold the wire in contact with the inner tube - would lead to wire temperature increasing faster than power input would suggest - ie what we see with supposedly increasing COP. Most likely means of construction is winding wires around an inner tube, or winding them around a different mandrel and then slipping them over the tube. Bonding them to the inner tube is an extra step that (based on inconsistency/variability of surface glow) has likely not been done and for which their would be little initial motive anyway. And massive relative thermal expansion of the wire (~1%) would likely have cracked any ceramic bonding or attempts to rigidly encase the wires or bond them to the inner tube anyway. Differential thermal expansion means that the internal tube/vessel is likely only bonded to the thermocouple end cap, otherwise the external tube would be broken by axial stress due to differential thermal expansion of higher temperature of inner tube compared to external tube.

Re: [Vo]:Determining the transmittance . . . of semitransparent materials at elevated temperatures
The system is way too complex for thermography to be able to deal with. I note that most black-body radiation for 1400°C: http://www.nature.com/ncomms/2013/131016/ncomms3630/images_article/ncomms3630-f4.jpg has majority of emission at 4um where the alumina transmittance appears relatively high in that fig 6 But a key factor is that even with only 10% transmittance if the alumina is relatively cool - say 1000°C then with 0.4 emissivity the power it is radiating is only about 2x that of the much higher radiative output 1350°C inconel wires+core reactor behind it. Even worse, because the transmittance drops off at longer wavelengths the power transmitted will be mostly at shorter wavelengths it will make the resulting spectrum look hotter than it actually is, which will skew the spectrum seen by the camera sees towards something that looks like a much higher temperatures. That is going to produce serious over-reading in temperature. This is all looking worse and worse the more I see.

Re: [Vo]:An expert reviewed and approves of this configuration
It seems clear that the thermography is way off - because the built in inconel heater wires would fail at 1350°C. (The peak temp from thermography is 1412°C). And the wires would necessarily be much hotter than the external surface of the reactor - if they are wound tightly around an inner core with little or no conductive contact with outer shell then that outer shell will only be around 1000°C and there will have been little or no LENR output.

It would crack and break letting oxygen in, particularly if made thicker walls. The external surface crenellations would create stress concentrators that would only make this worse. Resistive heating wires inside the alumina tube must necessarily be a lot hotter than 1450°C in order to push 900W heat into reactor. But there are no non-refractory heating wires that can survive such high temperatures. Refractorys can't handle oxygen exposure, and in some cases are no good with lithium or hydrogen. The wires have to be joined to non=refractory wires before they contact air and yet at those joints must not melt the non-refractory wire either. I am also not aware of electrical feed-throughs that can handle such high temperatures. 1455°C Ni melting point, but nano particles of metal have depressed melting points. http://en.wikipedia.org/wiki/Melting-point_depression The fuel/reaction particles as the source of all the heat would need to be at a temperature far above the internal reactor surface temp of 1450°C, probably at least 50-100°C higher, in order to radiate/convect the heat away to the walls. So at 1450°C we can expect that the Ni fuel particles are much hotter, and liquid, making for rapid mixing. Forget special crystalline structures created by secret processes. LENR in a liquid matrix seems to run counter to a lot of theories. Lithium vapour pressure at 1450°C is around 5-10 bar, with approximately .01g of lithium in reactor and perhaps 20-30mL volume that means nearly all lithium is in vapour state or as Li liquid condensate on relatively cooler reactor walls. This reactor is mostly nickel droplets in lithium gas (the hydrogen will all diffuse away through porous sintered alumina rapidly at such high temperatures, but perhaps is useful to create reducing conditions initially). This internal lithium vapour pressure would also add to the physical stress on the alumina - probably 5-10MPa, which would likely cause a failure given any other stresses (such as aforementioned heat flux induced differential expansion stresses). Nickel vapour pressure is around 1Pa at 1500°C, so in a month long test we can expect that along with liquid state of Ni fuel droplets' continual evaporation and condensation, dissolving in lithium condensate of Ni within the reactor vessel will lead to steady mixing between the droplets. Li + Ni vapour will condense into a thin layer on the cool walls of the reactor - basically acting as a lithium heat pipe and create very consistent all-over temperatures. Perhaps with small drops of lithium condensing and rolling down sides with some dissolved Ni, or otherwise simply leaving a thin coating of Ni and Li on walls. Alumina is strongly attacked by liquid lithium reacting with it to form new compounds - I would expect it to be quickly consuming the available lithium in the slightly porous alumina. And we do see that Nickel ash has very little Lithium (.03%, down from 1.17%) Basically all fuel should end up very homogenous. Liquid Nickel dissolves alumina and oxygen to a small degree- about 1.8% and 1.6 % respectively, but only 0-.05% aluminium in analysed ash - that probably indicates something in error http://docs.sadrnezhaad.com/papers/176%20(Interaction%20Crucible%20NiTi).pdf If there is a secondary smaller sealed reactor vessel within the alumina tube then if must be even hotter. So so questions that need to be answered: 1/ Why isn't there more aluminium in ash given claimed temperatures? 2/ How does theory deal with liquid Ni as the LENR matrix? 3/ How do heater wires survive these temps without melting - it is well beyond temps that non-refractory metals can withstand, particularly given that they must be a lot hotter than the reactor itself, and refractory metal wires would fail at external joints. Not to mention non-leaking feed-throughs of heater wires into reactor while maintaining seal integrity is probably not possible at such high temps due to differential thermal expansion of metal vs ceramic and limited strength of materials. 4/ If within the reactor itself how do heater wires survive exposure to 1450°C lithium without dissolving/disintegrating. 5/ Given claimed heat flux and internal

Some questions on the thermography: Did they do thermography on all sides or only from front? If so how do we know that there wasn't some insulation internal to the alumina that restricted the heat output from the sides + bottom that were not recorded? The tube radiation would have heated the frame underneath the tube a lot, and that would have meant that the air rising through that frame and past the tube would not be at room temperature, but rather at higher temperature and lower density, so the convection calculations are likely to be significantly in error - but would require modelling in CFD to give an idea as to how much. Did they observe significantly cooler sides on the tube compared to the top and bottom? natural convection should cool the sides a lot more than the top or bottom of the tube due to the higher air flow velocities in those regions. In fact the heat transfer and temperature differences created by natural convection could be modelled with CFD and would be a way to validate the power output via radiation.

Li + Ni vapour will condense into a thin layer on the cool walls of the reactor - basically acting as a lithium heat pipe and create very consistent all-over temperatures. Perhaps with small drops of lithium condensing and rolling down sides with some dissolved Ni, or otherwise simply leaving a thin coating of Ni and Li on walls. Alumina is strongly attacked by liquid lithium reacting with it to form new compounds - I would expect it to be quickly consuming the available lithium in the slightly porous alumina. And we do see that Nickel ash has very little Lithium (.03

Fig 12b. page 26. Only just notice that they say they are inconel resistance wires. But how can the resistor wire, external to the reactor, glow more brightly than the reactor itself (implying it is hotter)? Also if the reactor external surface is at 1250-1410°C, then on top of the 30-50°C temperature drop through the walls the resistive wire would have to be even hotter (up towards 1500°C) in order to be able to radiate the 900W! And there are no inconel metal wires that can survive such temperatures in air for a month. http://www.engineeringtoolbox.com/melting-temperature-metals-d_860.html There is also a mistake in their discussion for these figures, the metal resistors within the reactor would necessarily have to be hotter than the reactor itself if they are to be able to output heat into the reactor. But then again at 1450°C inconel resistance wires would have turned into puddles anyway. The 2mm high fins on the outside, subjected to convective air cooling would be 30-50°C colder than the base of the fins due to the longer conduction path and hence greater temperature drop through the alumina. And that should influence the thermography to under-read, but also means the temperature within the reactor would have to be even higher to create 1400°C average surface temperature. So this proves that the thermographic temperature readings are off by a very long way - at least 150-200°C too high if inconel wires that max-out at about 1300-1350°C were to have survived for a month. We now know there is a huge error, we just don't know the source of the error, or how big the error is.

Re: [Vo]:Engineering and materials issues with high temperature hot-cat Lugano demo
they dropped the powder in through a hole and then sealed it with alumina refractory glue around a metal thermocouple (why are its readings not reported???). Apart from the fact that the 'glue' would have residual porosity that would probably help vent all hydrogen at high temp that is pretty strong indicator that there is no refractory metal shell in there to prevent leakage if that is a big deal. A metal shell would tend to shield any pulsed magnetic field that Rossi claims is critical to operation. Also a metal shell would need to be insulated to prevent shorting of the resistor wires, and all of that would make the inner vessel even hotter - which seems pretty undesirable. An observer there for the opening reported no such refractory shell (though might be under NDA). And lastly refractory metals are heavy. A quick check of density of alumina and exterior size of reactor all weighing under Fig1 452g with resistance wire inside is a strong indication of no such additional components being inside.

Re: [Vo]:Engineering and materials issues with high temperature hot-cat Lugano demo
inductive heating works based on the area of the conductive loop cut by the changing magnetic field, the rate of change of the magnetic field and the conductivity of the material. Consequently microscopic powder made with high resistivity hot iron/nickel will have extremely weak response to any low frequency inductive heating. If inductive heating was the way ahead a microwave source delivered through a waveguide or exterior cheap off-the-shelf high-frequency inductive heater would be far more effective (and easier to implement) than crude resistor wires.

if there was an inner metal cylinder to contain reactants (particularly insanely leak-prone hydrogen at high temperatures) then it would be sealed by welding not half assed approaches like alumina glue. Until you have worked with hydrogen (I worked with stirling engines containing hydrogen) it is hard to appreciate just how disrespectful it is of things like hermetically sealed containers and thin walled materials of all types. Anyone with similar experience would find the idea of such a small reactor with low volume small fuel charge and large thin wall operating for a month at 12-1400°C while retaining hydrogen fuel totally unbelievable. Also alkali metals are nasty on all metals that I am aware of at high temperatures - particularly in heat pipe type applications like this - pure lithium condenses on cooler wall surfaces, instantly dissolving metal atoms from the surface and washing them away to the hot zone where the lithium is evaporated. This leads to fast corrosion/eating away of basically all metals as they are all slightly soluble in lithium, made worse by elevated temperatures.

Re: [Vo]:Engineering and materials issues with high temperature hot-cat Lugano demo
1% lithium in 1g fuel, so 0.01g, boils at 1342°C. At 1 bar,1342°C would fill about 180mL volume, reactor volume probably about 30-50mL so will be filled with lithium gas under pressure - operating as a heat-pipe to equalise pressure. I have just realised that we can probably infer the existence of an inner reactor vessel because we see helical wires or wire shadows of only one angle - we can't see both sides of wire helix through an open core because there is an inner core vessel in the way. I had thought there was no such vessel, so my conclusion about the wires being hotter no longer stands up. The wire temperatures are electrically controlled to alter the amount of radiative heat flux that leaves the inner vessel - a crude method of controlling heat flux that suggests great improvements in COP if better methods of heat flux control are employed (high temp coolant fluid or moveable insulating shields). That inner vessel must be crazy hot! around 300°C higher than the already hot outer wall in order to radiate the heat to the outer wall and hot wires; eg if Ø20mm outer wall is at 1200°C (approx max given revised COP of around 2 from temp reading that is obviously in error due to non-melting of inconel, though could be significantly lower) then an inner alumina tube of Ø12mm outer diameter radiating 1kW would need to be more than 1500°C surface temperature (Actually higher given hot wires surrounding it), so again it seems temperature within vessel must be up to range where nickel is melted and lithium is gas at 5-10bar. I wonder if that smaller hotter inner tube and translucence of outer alumina tube is what is screwing up the thermographic calorimetry? If the camera is picking up the inner tube at 300°C temp higher than the outer then the exterior tube temp might only be 1100°C and the COP could be a lot lower On 13 October 2014 10:01, David Roberson dlrober...@aol.com wrote: The amount of lithium seems to be tiny from what I have read.

The light emitted does not have a color that matches what is expected to be seen from a surface of a broad band black body. I wonder if anyone on the list has seen materials with that characteristic. If you consider the behavior of a RF radio transmitter, you will understand the jest of my question. In that case, the amount of power at its transmission frequency, being narrow band and so low in Hertz, would indicate a black body that was at an enormous temperature if the complete spectrum were available as expected. But we know that it does not represent a true black body since it is narrow band. Can anything of a similar nature exist at other frequency ranges such as IR? Sorry about the rambling, but it is getting late and I am quite tired.

[Vo]:E-cat Lugano demo probably had no output.
Appears that there was an inner reactor vessel wrapped with helical resistance wires (hence shadows) from size of wires and necessary wall thicknesses this vessel is likely around 12mm diameter. Inner wall area of outer finned tube about Ø18mm, 0.2m long .0113m² Inconel metal resistance wires can only survive a maximum of about 1350°C without melting (actually probably lower than that over a month long period) From photo 12a/12b the wires appear to be covering less than half of the core reactor vessel, giving them an area of (estimate) .005m² (this is only a guess) We know that they dissipate 900W of electricity, and inconel has emissivity of around 0.7. In order for finned tube inner wall to absorb 900W from the wires at 1350°C they would need to be around 1000°C. At that temperature they would also transfer approximately 900W to the external environment via radiation and convection. If the inner reactor was any hotter or adding any heat to the system then it would necessarily increase the finned tube wall temperature to increase dissipation to environment, that would in turn increase the wire temperature greatly, including a further bump from the radiative heat transfer from reactor to resistance wires, increasing their temperature to far above the point of failure. These numbers are only approximate (this is a crude calculation only), but I think that quantitatively at least it appears that there is a strong possibility that this demo was producing little if any power, based on pretty simple physical constraints. And most certainly not the 3.8 COP claimed. As to the explanation for the high temp readings - I suspect the IR camera was picking up the colour of the resistance wires and inner reactor vessel body through the partially transparent alumina to give an artificially high temperature reading.

Re: [Vo]:Pomp weighs in
so the claim is essentially that this soup of elements were also consumed to exhaustion, without changing power input or output as their quantities reduced, in an amazingly perfect process that has as its only product the highest binding energy Ni62 (also consuming Ni64) and without creating any observable radiation during the process and no radiative ash.

Re: [Vo]:ECAT Active Cooling Control
you can get tremendous thermal conductivity by using smaller tubes. hypodermic stainless steel tubing is made cheaply and in very large quantities. Alternatively (and more easily) use a pump to actively circulate the fluid. But having heat sink fluid close to same temperature of reaction with low thermal resistance between the two is key to getting rock-steady control. Forms a much harder wall against run-away thermal events. Above the critical point of water 374°C and 22MPa you do not get steam bubbles forming - as is a supercritical fluid (single state). in nearly 3 years with many flawed demos Rossi has not demonstrated any particular talent for practical management of engineering thermodynamics, (defkalion showed more much more sensible approaches, even if their heat generation may not be working as well) so I do not expect the seeming control-freak Rossi to do anything particularly clever or even sensible in this respect now or in near future.

The water filled tube would absorb relatively little energy until the rector temperature rose above it's set point, at which point it would absorb a huge amount of energy with small temperature increase.

First, I applied normal heating to the device which leads to thermal run away conditions if allowed to go beyond a certain critical core temperature. As expected, the model showed that the ECAT began a path toward melt down. The path to destruction would proceed even when the original drive is removed since the critical temperature was exceeded. Then, I allowed the model to continue heating for a period of time and applied the brakes quickly with a new load that withdraws a significant amount of extra heat power from the system. This might be possible in real life if for instance a phase change coolant were sprayed onto the core directly. The extra cooling must be applied continuously while the temperature drops and until an optimum trip temperature is reached. The turn around point must be above the normal critical temperature since no additional heating is required to achieve a condition where thermal run away can begin anew. The model demonstrated that this type of cycle could be repeated indefinitely while the total power being generated by the device is significantly above that safely obtained by heating control alone. I would assume that a cooling method similar to that suggested above would take less input power than the standard heating process that I have modeled earlier so this type of control would result in a higher COP for the system. The model also demonstrated that a continual application of the extra cooling resulted in the cores return to room temperature as desired. Actually, the powerful cooling was not required to be applied once the critical run away point was passed. In this case, the core would be subjected to positive feedback that forces it toward turn off by itself. It is evident that a hybrid type of control system that uses both power resistive heating as well as active cooling would perform the function. If both techniques were available it might be possible to keep the ECAT temperature very near the critical point in which case the COP would be extremely high. For this type of tight control to work the loading as well as all the other parameters which cause the critical temperature to vary must be kept under tight control. This might be possible. Good to see someone thinking! In fact I think the problem is really simple. (And there should be no extremely high for overunity devices - if they are not beyond infinity then you haven't got an engineer worth his salt working on it). There should be no need even for an active system. You simply need a passive system that presents a steeper load onset

Totally agree Andrew. Rossi is possibly snatching defeat from the jaws of victory by not allowing sufficiently clear measurement.

They certainly should not take the position that since we can imagine a possibility where the proof is not conclusive that we can then, 1) ignore the results, or 2) without proof of the imagined exception conclude NO proof exists. You seem to be insisting on black or white even to embrace the possible. This the kind of silly position taken by Cude.

[Vo]:Why did Rossi prevent detailed measurement of the power input?
This has only just occurred to me, but in my mind is a bit of a red flag: The reactor vessel is a sealed metal container, no electrical or magnetic signal of any frequency will penetrate it (It is a faraday cage). And all of the resistive heating elements are positioned around it, so they do nothing but deliver heat to the reactor contents - no special magnetic or electrical excitation can pass through the reactor vessel. All of these configurational details were revealed to the testers by Rossi. So why did Rossi feel the need to prevent detailed analysis of the input power to these resistors that are no more than resistive heaters? We know he ran it in at least a partially pulsed 35% on 65% off mode with period of about 6 minutes from the thermography. So what possible harm could have come from allowing continuous measurement of voltage drop and current flow through the resistors? As such preventing that measurement serves no sensible purpose that I, or any other engineer/scientist could see, it is a pointless obfuscation. All it achieves is raising suspicion about just what electrical power is really flowing through those resistors.
Re: [Vo]:Why did Rossi prevent detailed measurement of the power input?
To repeat myself, there will be no significant em field penetrating the reactor. So don't try to fool yourself that there is some special secret about using em fields to instigate or promote the reaction, also Rossi has claimed in past to have it running using gas heating. Rossi's setup only allows for heat to get in. The skin depth of the 3mm thick SS vessel will exclude all fields above probably about 100-200Hz entirely, and will greatly attenuate lower frequencies as well (DC would get through) but the surrounding magnetic fields in the resistors themselves are very weak anyway. (not that many turns). If he wanted or needed magnetic fields to penetrate the reactor then he would not be using spiral wound resistors arrayed around the reactor vessel, he would have a coil wound around the reactor vessel. As such preventing measurement of current and voltage through the heating resistors looks very suspicious - as there is nothing there to be sensibly hidden if we take him at his word.

Re: [Vo]:Why did Rossi prevent detailed measurement of the power input?
Mark, please note I have design experience in electromagnetics (postgrad degree in EE machine design) so as I said excepted DC (in common electrical engineering parlance that is the non-time varying portion) and possibly some very attenuated low frequency (100's of Hz) EM my point remains. Rossi is (to me worryingly) needlessly obfuscating/preventing measurement of voltage current and so power in resistive heaters, because they do no more than supply heat to the reactor, there is no other magic in what they contribute.

Re: [Vo]:Levi Hot Cat paper is a gem
Have a bit more of a think about it Jed, IR laser beams wouldn't need to be any more intense than the heat being radiated by the E-cat. In fact by shining in from multiple directions they could be less intense than the emitted heat from the E-cat (like concentrating relatively diffuse sunlight to make something hotter at the focus point). So how would that burn or blind people? Are you burnt or blinded by looking at something glowing red-hot? As for the other; are you seriously disputing that 2kW of AC electrical power could be sent through those wires to the Ecat? Take test 1: If 400V rms AC was connected then that is only 5A rms which a 1mm diameter copper wire can easily handle. Now set up your 'visible' signal to be 50hZ 400V 2.5A turned on about 1/3 of time. Meter detects this with ease. Add a 50khz AC 400V rms 4A rms AC supply to that and you deliver another 1600W that is invisible to the low frequency sensitive meter. Knowing more about the meter would allow more sophisticated choices to beat it. DC might also be undetectable depending upon the instruments used. Neither of these scenarios is likely, but they don't appear to be ruled out by what is published. The November melt-down demo is also very interesting.

Re: [Vo]:Levi Hot Cat paper is a gem
An IR laser wouldn't need to be intense, it/they could be spread out over a wide beam/spot, not eye dangerous, and not particularly noticeable if you weren't looking at it and you were in close proximity to the hot e-cat (could even be optically triggered to turn off off if someone moved in front). Not saying it was done, just that it could be done, and would only cost a few $1000s at ~$4/Watt for laser diode bars. And Andrew makes a valid point about the power supplies. Clamp ammeters are a bad solution compared to inline resistance measurement, + voltages across all the wires. The meter in question can measure harmonic distortion, but looks at a primary frequency and assumes balanced 3 phase AC, so an additional high frequency, DC or other distortions would likely be invisible to the meter. It appears that these clamp ammeters on this AC optimised meter cannot measure DC, which is unfortunate seeing that some Hall-Effect type clamp ammeters can. http://www.pce-instruments.com/english/measuring-instruments/installation-tester/clamp-meter-pce-holding-gmbh-clamp-meter-pce-830-1-det_56526.htm?_list=kat_listpos=12 Most three phase sources also have a ground wire, that would be unlikely to have been checked for current (I doubt the testers could check this with the equipment they had without disconnecting the power supply, which they probably couldn't during the test). And the possibility of a DC supply grounded through the frame would also need to be checked - could be done by putting clamp around all wires, just as for the 3 phase power supply. Point is that it looks like it might be possible to hide additional electrical power supply within what the testers looked at, and we don't have enough information from the testers to check on all of these issues, however it is possible that they performed sufficient checks. I am on balance fairly convinced, but like many I harbour doubts about Rossi based on his dodgy history and apparent willingness to mislead at times.

Re: [Vo]:3rd Party Report Released
Haven't commented here in a while, pretty excited that after a couple of years of Rossi's shenanigans it's all perhaps about to happen. But I come from a hard test and measurement background (mechanical and electrical engineer, specialising in thermodynamics) and am by nature quite skeptical, so while compelling I am still not totally satisfied with this demo in Rossi's own facilities using Rossi's own equipment and setup. That is singularly because it relies upon Rossi being honest - something of which I am not totally assured given his history (I thought his Mat Lewans demo looked distinctly dodgy, and some of his others weren't great either). And I can think of a number of ways of cheating to get heat into the reactor: Altering the electrical measurement equipment supplied, fiber optic lasers hidden in cable, two-strand wires inside wired clamped ammeters (no net current), infrared, uv, x-ray, or radio frequency heat sources directed at reactor from afar, delivering combustible fuel into reactor via wires/cables (0.05g/s for 2000W). Probably most of these could be ruled out by the observers present, but as they are associates of Rossi I really don't know if they were looking for such. It would have been a far better approach for Rossi to engage aggressively skeptical testers to do the job. http://www.pce-instruments.com/english/measuring-instruments/installation-tester/power-analyzer-pce-holding-gmbh-power-analyzer-pce-830-1-det_60706.htm Anyway I look forward to more demos in preferably neutral locations to assuage my concerns.

In the previous test, they just assumed emissivity is 1, meaning as bad as it can be. It makes no sense to assume no convection. There has to be convection. Also, as you see in Fig. 10, the flange is large and it must be radiating and convecting a lot of heat. They did not try to measure that.

Re: [Vo]:Bribing 2,000 climatologists
Jed the issue is not the warming, it is the attribution. As all scientists know correlation does not equal causation. - particularly true when we are only looking at a couple of decades out of a series that is literally billions of years long. There are demonstrably (historically any time before the 1950's) other large and mostly unknown causative effects with huge influences that are not CO2. Take for example temperatures spiking upwards by about 1.5°C at the start of the Minoan and the Medieval Warm periods 3300 and 1100 years ago, and about 1°C at the start of the Roman warm period: http://www.climate4you.com/images/GISP2%20TemperatureSince10700%20BP%20with%20CO2%20from%20EPICA%20DomeC.gif these other causes are as yet unknown, and cannot be ruled out as drivers for modern warming - and the 1100 year periodicity of Minoan-Roman-Medieval and now modern Warming should make any scientist suspicious of what is driving our current warming. So when you see that 97% figure quoted the remember that the question asked was: Do you think human activity is a significant contributing factor in changing mean global temperatures?: * http://opinion.financialpost.com/2011/01/03/lawrence-solomon-97-cooked-stats/ * I am surprised they could find even 3% that would deny warming is occurred during the 20th century, and how could humans not be having some influence? How could anyone answer such a question in the negative? It's patently a ridiculous (and politically loaded) question to ask when the data is so unequivocal. But to then quote that as support for the IPCC consensus is disingenuous at best. What is needed is a more nuanced question asking opinions on what proportion of recent warming is produced by CO2 - and say 5 bins to group responses, and a similar question on likely future trends. This is sadly not something that any IPCC aligned group wants to ask because they wouldn't get the black and white result they need to support their particular its all CO2 belief system. And despite what you might believe there are very large numbers of professional scientists who doubt the validity of the IPCC CO2 driven thermageddon thesis eg 3+ including 9000+ PhD's in this one petition: http://www.petitionproject.org/ On 5 December 2012 02:12, Jed Rothwell jedrothw...@gmail.com wrote: Some people here think there may be a conspiracy of climatologists to bamboozle the public.

Re: [Vo]:How bad is this news? Jed Rothwell
Jed, the argument from authority approach with regard to climate change doesn't work because there are so many highly educated dissenting voices, so many examples of deficient analysis work in Climatology (check out Climate Audit), and yet seemingly so little interest in improving woefully bad scientific practices amongst climatologists. No one (with a brain) disputes that we have experienced warming during the 20th century, and most agree that CO2 increases are causing some warming, but there is way too much evidence that chalking it all up to increases in CO2 is wrong. Predictions of several degrees of future temperature rise are based on extrapolations of a temperature increase from 1980-2000 that has since halted, but that rise was similar in size and speed to the 1920-1940's - which was before CO2 took off. The projections of catastrophe are further founded on assumed large positive water vapour feedbacks multiplying the impact of CO2 by 2-8 times that are looking less and less tenable as more data is collected. A rather nice summary of uncertainty in that at: http://judithcurry.com/2011/07/05/the-ipccs-alteration-of-forster-gregorys-model-independent-climate-sensitivity-results/ Amongst the many holes: - CO2 started rising sharply in the mid 40's, yet the world then cooled for 30 years till the mid 70's. - world has not warmed in the last 15 years (how much longer does that trend need to continue before IPCC acknowledges their model predictions are wrong?) - missing tropospheric hot spot that is a central prediction of CAGW climate modelling (in other branches of science failed predictions = failed theory/model, but apparently not so in climatology) - lack of acceleration in sea level rise during last few decades - the rate is basically unchanged for 80 years (since before significant CO2 rise) - temperatures that have varied by 3°C during the current interglacial (holocene) for unknown reasons. - temperatures getting colder as CO2 level rose during last 7000 years of holocene (since holocene climate optimum that was a lot warmer than today) : http://www.climate4you.com/images/GISP2%20TemperatureSince10700%20BP%20with%20CO2%20from%20EPICA%20DomeC.gif - unexplained 1100 year periodicity in historical warming (Minoan Warm period, Roman Warm period, Medieval warm period, next one in that series would be ... now, but no, this time it's definitely all CO2. - no explanation as to why 18th century little ice age (basically the coldest period in last 8000 years) occurred. - claims of worse storms, droughts, heat waves, floods etc in disagreement with historical data. - Global Climate Models do not account for very long period ocean and thermo-haline circulation processes that appear to dominate climate as evidenced by the well known 60 year PDO and AMO cycles. - GCM's do not account for noted correlation between sun-spot cycle and temperature. - GCM's not even remotely capable of modelling cloud physics (and quite probably never will be given difficulties of modelling cloud nucleation, and associated convective circulation process on a grid that is fine enough to be useful, turbulence modelling on a mind numbing scale). You cannot hope to get modelling right if you can't accurately model cloud formation, as even a 1% change in cloud cover has more effect than CO2. - GCM's tuned in post-hoc manner by fudge factors like aerosols when the the historical concentration and distribution of aerosols is not known, and even if they were known their actual influence on climate is not known (being tied up with cloud nucleation physics and some really hairy light propagation physics). Exceptionally poor practice that is more augury than science. Most educated people, particularly anyone with a background in STEM find that the more they look into catastrophic CAGW the less convinced they are. In fact you could say that it is a perfect example of a positive feedback system in human terms when the proponents (Climatologists, Activists, Politicians, Corporates involved in carbon trading) of CAGW get ever more power and money for creating and promulgating bigger and badder scare stories. It's naive to think that the IPCC could ever let the message be a balanced one of scientific uncertainty in the face of such powerful and venal motivating factors.

Re: [Vo]:A dreadful price to pay
Another hyperbolic Climate Change scare story. Arabica is grown between 600 and 2000m altitude. At typical 0.65°C per 100m lapse rate in tropics that is a about an 8°C temperature range. The world warmed by 0.7°C last century, (though no rise in last 15 years) so that the same temperature occurs 100m higher up the mountain, and seemingly current coffee production is doing very well. If the world heated up by a further 2°C then the optimal growing region might be 300m higher. In Jamaica Blue Mountain Coffee is grown between 900 and 1700m elevation - a range of 800m or about 5°C One wonders how these coffee plants ever survived the 10°C colder temperatures of the last ice age, or the 3°C hotter temperatures of the Holocene Climate Optimum 5-9000 years ago.

This support is perhaps not totally surprising given their recent record of being run by the number 1 most evil man in history: From 1958 to 1962 Mao's efforts to collectivise China caused roughly 53m unnecessary deaths. Most of these were by starvation- perhaps 15% by the deliberate withdrawing of food from 'undesirables' (that is those who opposed the madness ). People who were too old , too young or sick were also denied food. In one town the locals queued night and day for the opportunity to dig clay that they then ate.- 250,000 tonnes of it. Many of these people died of constipation, others from ruptured sphincters. 5% to 10% of the total deaths were by executions or beatings. At this time China was shipping food to Soviet Russia, East Germany, Albania and Cuba to maintain the pretence that there was no famine. In socialist fervour, local cadres inflated local harvests- to the point that when the state then took it's 30%, there was none left at all. The hierarchy were not fooled by these inflated figures- but they took the harvests anyway. Today Mao's birthplace it was basically a shrine with thousands queueing up daily to worship the great helmsman. What is wrong with the Chinese? It scares me that such people will soon run the world.

Re: [Vo]:Save the Balloon!
Accumulated alpha particles from radioactive decay collecting in gas trapping rock formations. Basically a non-renewable resource after we have worked through available supplies of shale gas. Helium can be extracted from the atmosphere - about 5ppm, but will probably cost ~$5000/kg. Nuclear reactors make a relatively tiny amount, but may be useful when we run out. As this is not really going to be a problem for 100's to 1000's of year yet, we can probably economically scoop-mining Saturn or Jupiter with a fusion powered tanker, though it will cost a lot more than current prices. For a lot of cryogenic applications Hydrogen (14K melting temp) or Neon (24k melting temp) can be used instead of Helium, particularly as high temp superconductors are more widely adopted. For lift gases we will have to use hydrogen, methane or neon (renewable from atmosphere) instead. Neon would be fine for party balloons, will cost a few dollars per balloon, and won't leak away as quickly, so not really much worse than Helium. I doubt it is worthwhile anyone investing in large scale bulk storage of Helium as speculative investment. Though if LENR replaces Natural Gas then cheap Helium will run out much sooner.

On top of which I don't think that you want large thick bundles of fuel in a reactor if there is a positive temperature coefficient to the reaction. Want thin layers with good cooling everywhere to prevent run-way hot spots from forming, or perhaps powder in a fluidised bed where the powder rapidly convects.

[Vo]:Bussard Ramjet
One of the cool things about Ni-H LENR is that it has the potential to make Bussard Ramjets more feasible (assuming it is H-H fusion as now seems most likely). A Bussard Ramjet is a Rocket that scoops up hydrogen from the interstellar medium using a vast magnetic and/or electrostatic field, then fuses it and fires it out the back. The concept has always had a major flaw in that hydrogen is nearly fusion-proof in conventional hot fusion except as part of Carbon-Nitrogen fuel cycle. Even if that whole fusion reaction happened in a LENR cell and the power conversion requires a heat engine the energy could still be used to drive a particle accelerator that accelerated the ash (Helium?) out the back. You would essentially never run out of fuel (so long as your LENR lattice does't get used up), so possibly much faster trips to the stars without the requirement for ridiculously large exotic (deuterium, lithium or He3) fuel storage tanks. Speed might still be limited to a few % of c, but even that looks pretty good from where we are standing now, as they can also be used for decelleration and Bussard LENR ramjet ships might be a lot cheaper and more compact than what was hither-to thought possible.

I no longer think it was ignorance on Rossi's part that lead to such consistently bad calorimetry and ambiguous results, he was trying to create uncertainty and wiggle room for himself to be able to exaggerate his results. It is notable that the few independent groups of testers that really had proper access to check results (NASA linked group, Defkalion now Swedes) have all had tests that were either didn't work or under-delivered on promises, would love to hear from insiders who were there.

Re: [Vo]:High temperature E-Cat - preliminary report published
http://www.e-catworld.com/2012/09/high-temperature-e-cat-report-published/ No glaring problems. Though for the life of me I can't work out where the reactor is in the arrangement - they detail the outer and inner tubes (which are not the reactors, their mass is consistent with dense 310 SS, inner tube 1.375 OD x.08 thick, outer 3.375ODx.064 thick ), Resistors (look like tube furnace), ceramic putty and paint, but as far as I can tell no indication of what the reactor is, size, shape, weight - is it lumped in with the 2.2kg resistors? COP about 2-2.5, 18kWh output and 8KWh input. Calcs are reasonable and probably conservative. To be honest I think this 2ish COP might be close to what Rossi has had all along - just not quite good enough to be commercially useful. Earlier claims of higher COP might have been either his poor calorimetry, or deliberately misleading, but either way this demo is probably more convincing than his previous tests Criticisms: Calorimetry is still not good and lack of instrumentation is Rossi at his time wasting worst, don't like the thermal camera - as I lack familiarity with them and don't know if it requires calibration or is subject to significant errors I don't know about, or if its readings could be intentionally manipulated in some way. Was it Rossi's or someone else's? Perhaps others may be able to confirm its accuracy. Small temperature differences make huge power differences in radiative emissions (double power for increase of 200°C) - so errors are magnified. No thermocouples is just silly. Input power measurement between control box and wall were inconsistent (why?). Any checks of hidden power supplies in control box? No ability to tell if their were unmeasurable higher frequencies coming from wall. He needs an aggressive sceptic to do a proper test, not someone in his circle or in his employ. Skeptics hat: Not enough detail about reactor, could have been combusting a fuel for example (off top of my head) aluminium powder + hydrocarbon in air that would have same weight at start and finish,1kg would be enough to supply 10kWh heat seen Celani is doing a much better job of convincing people.

Just realised, if top of reactor was significantly cooler than bottom then all power calculations would be bollocks. Were there checks done on this and could the internals have allowed such an uneven heat distribution?

If Celani can make it self sustain, this will be as conclusive and irrefutable as the Fleischmann and Pons boil off experiments of 1992, which produced massive heat after death. It was easily measured and far beyond the limits of chemistry. See: http://lenr-canr.org/acrobat/Fleischmancalorimetra.pdf These 1992 experiments did not convince any prominent skeptics, because those people are pathological skeptics who have abandoned the scientific method. Or because they are scientific illiterates such as Taubes, the Wikipedia editors, or your typical mass media science writer. They do not understand middle-school level science. They have no idea what the limits of chemistry or 4 eV per atom means. A self-sustaining gas loaded experiment by Celani will not convince these people. They will: 1. Ignore the results OR, 2. Misunderstand the results. 2. Come up with absurd reasons to dismiss the results. 3. Accuse Celani of lying. You must ignore such people to preserve your sanity. Dealing with them is a no-win proposition. Never try to address their concerns. They will only invent one crazy objections after another.

Akin -- a member of the House Committee on Science, Space, and Technology committee no less! -- who imagines that women's bodies have a magical ability to avoid pregnancy after rape. If Celani takes the right steps he can easily convince a hundred thousand sane, professional scientists and engineers. The right steps include: 1. Allow independent observers to confirm the result. 2. Present the results in a properly written paper with lots of details and data. 3. Allow me and others to upload the paper, the full dataset from the instruments, photos, papers from the independent observers, and other proof of the claim. As I said in presentation at ICCF17, addressing the researchers, [if you will only do this] you will be believed, you will be funded, and we will triumph. Whether Celani or any of the others will follow my advice or not I cannot predict. So far, every cold fusion researcher who has had the opportunity to convince the public has failed to do so.

Re: [Vo]:Dominguez ICCF17 abstract
Just how hard would it be to detect if Deuterium is the product in Ni-H LENR? I don't have good data on P-P=D fusion, but based on mass difference it releases about 2.31e-13J/deuteron formed. Assuming that to really produce a strong Deuterium signal in needs to double in concentration from about 1/6000th to 1/3000th in hydrogen that means that 1/3000th of the hydrogen in the reaction needs to be converted to deuterium. That means about 23MJ/gram of hydrogen needs to be released to double the deuterium occurrence. In Rossi's claimed 50cc ~10kW ecat reactor at 20bar (about 0.1 grams in hydrogen gas, significantly more in the nanopowder) that would only take about an hour. For Celani with 15W, and a reactor vessel of 200mL at 8 bar (about 1.3grams Hydrogen + whatever metal loading was) that would take perhaps 2-3 weeks, but might be tricky due to leakage of hydrogen through walls. Defkalion at about 1kW would be perhaps 1 day. Much tougher to see in non-gas phase LENR due to large inventory of H in the water. These basic calculations suggest that probably Rossi or Defkalion already know (my money would be more on Defkalion, given their better scientific practices), and that Celani might be able to find out in next few weeks to months (easier if he increases the power output using more mass of wire). So hopefully we should know one way or the other quite soon.

Re: [Vo]:Some doubts expressed about Celani demonstration
Is there any way to guesstimate – assuming the best reasonable kind of insulation is added to retain heat, something like aerogel, etc – how much more mass of active wire (if any) would be necessary to get close to a nominally self-sustaining system? ** ** Jones That would be very easy to do, no need for anything fancy, just wrap it in Fiberglass insulation and tape it on, like lagging a pipe. Quick mental calculation suggests on the order of 0.1W per cm of thickness per degree of temperature differential, so for 15W and 100 degree temperature differential you would need about 6mm thickness of fiberglass. Would only take 5-10 minute to set up. Bigger problem is stopping it from over-heating. Ideally need to surround it in a heat sink with a controllable temperature - eg 120°C so that as the reactor gets hotter than that it will rapidly start to transfer heat to the heat sink. Want the heat sink close to the reactor operating temperature (I think this was one of Rossi's problems in getting safe controllability last year) So put the whole reactor inside a really well insulated metal container filled with oil that can be heated up to as much as 190°C, and perhaps a way of dripping water into the oil if you need to get rid of heat (20cc water per hour would do it for 12W) The oil will prevent rapid thermal run-aways with it's thermal inertia.

Re: [Vo]:Some doubts expressed about Celani demonstration
From those numbers (30°C room, 120°C at 48W and 140°C when LENR active) I calculate 16W excess if you assume all radiative heat transfer. But it will actually be slightly less than that because the hotter tube surface will convect heat away at a rate that is roughly proportional to the air to tube temperature difference. The next level of complication is that the natural convection air flow will also be slightly faster due to the increased buoyancy, so the heat transfer coefficient will increase as temperature increases too, typically at a rate proportional to the temperature differential to the power of 0.25. I'll do the calculation assuming constant heat transfer coefficient and then with variable heat transfer coefficient caused by increased temperature, shouldn't be much difference due to relatively small relative temperature increase. From his paper he says that the tube dimensions are Ø40mm OD and 280mm long, I will use the full length assume that the temperature is the same everywhere due to internal convection of that most magical of heat transfer fluids hydrogen. Borosilicate glass has emissivity of about 0.9 so the tube is radiating about 27.4W at 120°C and 36.7W at 140°C in a 30°C environment. So 48-27.4=20.6W convected at 120°C and 20.6x(140-30)/(120-30)=25.2W at 140°C. Add that 25.2 to the 36.7 and subtract 48 input and you get 14W excess. Assuming that the heat transfer coefficient increases in proportion to the temperature differential to the power of 0.25 then the convected and therefore excess heat rises by about 1.2W to 15.2W All the same calculations repeated for a 25°C ambient temperature instead of 30°C drop the excess heat from 15.2W to 14.6W, again not much difference There might be a little more complication with the end caps etc, but I think you can pretty confidently state that it is over 10W. Also perhaps someone did a check on the temperature at the top and bottom of the outside of the tube to see if there was a significant temperature difference? I think it is pretty unlikely but you never know. On 18 August 2012 01:53, Jed Rothwell jedrothw...@gmail.com wrote: Several experts in calorimetry expressed doubts about the Celani demonstration at ICCF17. Mike McKubre in particular feels that it is impossible to judge whether it really produced heat or not, because the method is poor. He does not say he is sure there was no heat; he simply does not know. Others feel that he exaggerates the problem. There were concerns because Celani has programmed in the Stephan-Boltzmann law which multiplies things to the a 4-th power. Srinivasan worried that he makes a mountain out of a molehill. The temperature is measured at one point on the surface of the tube. I asked Brian of NI to give me the actual temperature readings. With 48 W of input power only, before excess heat or with the Ar calibration, in a room with 30 deg C ambient temperature, the temperature rose to 120 deg C. When the excess heat appeared it rose to 140 deg C. Celani says that equals 14 W excess, and that is what was displayed by the instrument. McKubre and others worry this may be caused by decreased pressure in the cell. However, the pressure fell only gradually, and stabilized in the last 2 days. They also worried about changes in conduction within the tube, and uneven heat on the surface. I do not think that such effects can account for a 20 deg C temperature rise, especially given the smooth line produced when there is no heat, with H or Ar. The temperature returned to the same level with 48 W, in Italy, Texas and Korea, after the gas had been changed out twice. Anyway, I would like to note that these people have doubts. Others agree with me that the method is crude but unlikely to produce such a large error. Celani hopes to run it in self-sustaining mode with better insulation. That will put to rest all questions about calorimetry. He hopes to do this as quickly as 2 weeks from now! More power to him. He has run it for as long as a month, so a 1 or 2 week self-sustaining run should not be a problem. Given the mass of wire, even 10 minutes would be convincing. - Jed

He was, but the story is a little complicated. He was severely beaten and then for some inexplicable reason they let him go. As described here, the family managed to get on a train and they escaped.

Re: [Vo]:The faint young Sun paradox
Probably the most sensible solution is that the atmosphere was significantly thicker. 30% less heat input would drop the earth's temperature by about 20°C, but 20% more mass of air would increase the temperature by about 20°C at ground level. We know that during the age of the dinosaurs that there was a lot more oxygen in the atmosphere, it was up to about 30% O2 vs 20% now. Assuming the quantity of nitrogen is about the same (pretty safe as it doesn't react significantly or leak away) then you are looking at another 10°C just in the extra thickness of atmosphere caused by that extra oxygen. Before about 800 million years ago the atmosphere had very little O2 and a whole lot of CO2, which would have made the atmosphere even thicker and further increased the temperature at the surface. Also the earth was spinning a lot faster and the thicker atmosphere transported heat better from the tropics to the poles, producing a wider latitudinal band of temperature climates (this is known from geological studies) On 14 August 2012 23:27, Harry Veeder hveeder...@gmail.com wrote: Models of the Sun's evolution predict the Sun was 70% percent as bright 2 billion years ago, and the Earth should have been an ice ball at that time.

Re: [Vo]:Detailed inside information about Rossi's 1000C test reactor
I'll top-post this reply to make it easier to read: What I meant is that the device does not look at all convincing, this release could be Rossi's way of getting some early feedback on the types of objection that critics are likely to have when he unveils it for his next set of demonstrations, so I am perhaps doing him that small service. :) Hydrides release hydrogen at higher and higher pressures as the temperature increases, increasing temperature from 500°C to 1200°C could increase pressure by an order of magnitude. http://upload.wikimedia.org/wikipedia/commons/7/7c/Metal_hydride_hydrogen.storage.graph.gif http://www.rebresearch.com/sorbers.html pressure would be increasing massively as your temperature increased - a very dangerous situation for a reactor that is rapidly losing strength. And this would be quite scary in terms of the lack of control over the reaction that it would give (depending on what the influence of pressure is upon the reaction). He apparently has no way of measuring or releasing pressure - again very dangerous, and he would be lucky not to have a dangerous accident if he was really using such a system. Even using only a small amount of hydride (not running at pressure equilibrium) you would then have a pretty dangerous situation with pressure increasing as metal strength decreased. at 1200°C all superalloys are extremely weak. And the rate of hydrogen leakage would also increase massively at such high temperatures - you would need some way to compensate for that leakage. And then there is the added problem of how to ensure that the source of your heat energy is not leaking and reacting hydrogen (they store a lot of energy). It makes no difference what the temperature is under the skin - like the earth's core is thousands of degrees, but the surface is only about 280K on average, and it is the surface that radiates (or convects) away the heat. Though the hole you point to does look to be more like 700-800°C it is only a tiny area, and will be radiating very little energy. Almost the whole surface is barely starting to have a hint of red - so the temperature looks to be under 500°C. His stories about not being able to get close because it was too hot sounds like rubbish, you can easily put your hands in front of a bar heater or radiant gas heater operating at the power levels he is claiming, and 13kW on the surface of a 1.2m radius sphere is only about the same heat flux as the sun has on a cloudless day. His statement about heat being radiated by inner walls sounds like he doesn't understand basic radiative physics, as all that energy must leave through the small holes at the end, those holes are the only area that count (in terms of the heat energy from the inner tube).

Temperatures, as the description reports, in this case are measured through laser thermometers and a thermal camera. So the visible electrical connections are all is needed to make this work. Again, it's a very crude device. But if it's just supposed to make a lot of uncontrolled heat, it could be more than enough for the job. Also unclear how this heat is being radiated away when there is only a small hole for the heat to leave through, and from the colour it doesn't look like it is over 1000°C (though
