    No. Once again, gray body equations have to reduce to black body equations where there are no reflections.

    No, they don't, because you still have an emissivity (which is the same as absorptivity, in a gray body).

    You're trying to have it both ways again. There is also a "scattering" term which you're ignoring, which is not the same as reflection.

  3. Nothing I read shows they took any significant security precautions whatsoever, either in the digital or physical security. It's not that hard to physically alter the device, the monitoring equipment, or the data if you're intent on fraud and there are no experts in physical and digital security constantly monitoring the integrity of the experiment and the equipment used to monitor it.

    Oh, for crap's sake. The question isn't whether their security is perfect. The question is "Which is MORE LIKELY: that a bunch of university researchers were fooled by a very, very damned good stage magician, or that a technology (nickel-based LENR) which has been studied for many years by both the U.S. Navy and NASA was finally figured out?"

    To me, the answer is pretty clear: the latter is far more likely and plausible.

    Since Jane keeps bolding "from the wall" and claiming that "radiative power from the walls through that boundary cancels itself out," Jane seems to be saying:

    Jane's power in = electrical heating power + radiative power in from chamber walls Jane's power out = radiative power out from source + radiative power from chamber walls, re-emitted back out

    No, that is NOT what Jane is saying. Jane is saying what Jane already actually said, not this distorted nonsense of yours.

  5. It's megawatt HOURS. And yes, I damned well do know how much that is. That's very close to 1.5 times the amount of electricity used by an average U.S. home in a year.

    That's anything but "tiny".

    It's not "power" that matters. It's power times hours, divided by mass.

    Your jet engines are in vehicles that way tons. And they go through tons of fuel.

    The amount of "fuel" that went into this thing was weighed, and it was about one gram. Nevertheless, they calculated power output for the entire mass of the thing, and still came up with orders of magnitude more power output than any possible chemical reaction.

    this thing could have one too because nobody is allowed to get a close enough look to see if any of those tubes running in are carrying fuel.

    NONSENSE. Read the goddamned paper. The whole experiment was set up by university researchers. They "got close enough", all right. They held it in their own hands, and wired it up themselves.

  6. Sorry, but no - you need to read the paper better, because you're jumping to conclusions that the paper does not support. Rossi did not only provide the test cylinders. He provided the pumps, control boxes, cabling and pretty much everything except the meters. Just like a stage magician provides everything except the eyes.

    Sorry, but no. You're not reading the same paper I am. The one titled "Observation of abundant heat production from a reactor device and of isotopic changes in the fuel".

    The word "pump" doesn't even appear in that paper. Not even once.

    There are so many ways he could have turned on an electric power source while supervising the insertion and extraction with his fingers, and rigged it so this power drain would not show up on the meters.

    What the hell? Nonsense. There is nothing at all here that would indicate that. The researchers themselves set up the equipment. Do you think they were incompetent? And no, there is almost zero likelihood that "extraction with his fingers" would have occurred, as he was being closely watched by several people, and he's a goddamned university professor, not a stage magician.

    And no, there is absolutely zero chance that he would manipulate the instruments, because they were being continually used and in some ways adjusted by the researchers. Rossi wasn't even there most of the time.

    I really have no further reason -- absolutely none -- to have to read this utter nonsense.

    That's why radiation re-emitted by the source at temperature T1 is (e*s)*T1^4. There are no other factors involved.

    Uh... I hate to tell you this, but this exactly what I have been saying all along. Except for the "re-emitted" part. I'd ask you what the hell you meant by that, if I really cared. (e*s)*T^4 is NOT "re-emitted" radiation. That is the total radiative output per unit area. So... Huh? What? Are you trying to say something here?

    The source can't re-emit radiation at (e*s)*T4^4, so those terms in Jane's equation can't cancel. And the last term double-counts radiation emitted by the source, so it's zero.

    The source doesn't have to "re-emit" radiation at (e*s)*T4^4, because none (NET) is absorbed in the first place. Again, this is what I have been saying all along. It is reflected or scattered. As I have stated before, this is a requirement of the Second Law of Thermodynamics.

    I made one non-thinking slipup a while ago, which I pointed out. Don't try to present that as a genuine claim of mine: we have it here in black-and-white that I was not genuinely making that claim.

    But yes, radiation inward from the chamber walls does cancel, because it is reflected or scattered and goes right back out. (A small part of it misses the inner sphere completely.) So no matter how you look at it, it is still a zero sum.

    So what is your point here? Are you trying to claim that radiation from the chamber walls is absorbed, and NOT re-emitted? That's a violation of the Second Law, because it would require energy spontaneously flowing from cold to hot.

    I don't care how you try to divide it up. Everything you've said ends up a violation of physics in one way or another. In fact you're pretty damned good at dreaming up ways to violate basic physical laws, it seems.

    Now you've gone so far off base, I can hardly do anything but laugh.

    This is such a hilarious pile of misinformation that besides just recording it for may later writeup, I'm throwing a copy in my joke pile.

    Maybe that's why Jane won't even take a few seconds to write down an energy conservation equation before he wrongly "cancels" terms. Deep down, maybe Jane suspects that he's wrong and mainstream physicists are right.

    The "mainstream physicists" are the ones who wrote the heat transfer textbooks I used to prove you wrong, dumbass.

    Let's cut to the chase.

    You insist that the radiant power output calculation of the heat source has to take into account the cooler temperature of the chamber walls. In fact the equation YOU gave for this several times is actually a heat transfer equation:

    (epsilon * sigma) * (T1^4 - T2^4)

    But that's NOT a power out equation, it's a heat transfer equation. Now, I'm only speculating, but I have a very strong suspicion that HOW you got this wrong, was that you read somewhere that this is how you have to calculate the radiant power output of a body.

    THAT'S TRUE, WHEN YOU'RE EXTERNALLY MEASURING RADIANT POWER, BUT NOT WHEN YOU'RE CALCULATING IT FROM FIRST PRINCIPLES.

    That's why I say: I suspect you saw this somewhere as a way to calculate radiant power from a measured result in an environment with "ambient" temperature. Because that is the only kind of place this legitimately shows up as a "power out" calculation.

    When you measure the radiant output of a source, such as a human body in a colder room, for example, you have to correct for the ambient temperature (as pyrometers in fact do), because your instrument is receiving not just the source, but also the "ambient" radiation. So you have to subtract the ambient to get the radiant power of your body.

    But that is not the case in Spencer's experiment. We are calculating the power from first principles, not measuring it externally. There is no "ambient" radiation hitting a measuring device which needs to be subtracted.

    You've argued this every which way from Sunday, as the saying goes. You've even argued it rather dishonestly, as I have demonstrated. But as it turns out, you were wrong 2+ years ago, and you're still wrong.

    And I still don't think you're a physicist. Or, for that matter, even willing to pick up an actual textbook on heat transfer and understand it.

  15. No, input cannot easily be monitored, unless someone trusted to be impartial can provide and set up the lines.

    Uh... excuse me, but did you miss the part where this is a controlled experiment, by reputable university researchers, not some magic show?

    This wasn't some "demo" by Rossi. He didn't let them see inside the cylinder, but other than that, it was in their control the whole time.

    Well, yes, that's exactly what it's like. The chain of custody is compromised, in that he does not allow the test to be set up in a 3rd party controlled environment, and doesn't allow them to replace any of the outside equipment that isn't part of the "trade secret" core.

    Uh... yeah, I guess you did miss it. That's exactly what this was. A 3rd-party controlled environment. The only thing they did not control was what might have been already in the cylinder. They were present when the "fuel" was put in but not allowed to otherwise look inside. Which, if you know anything about physics, is irrelevant to these results.

    It could not have been some kind of chemical "cheater" because there isn't any similar mass on Earth that could have produced the same power chemically. And the electrical power was set up and monitored by the researchers, not Rossi.

    If this was legit, Andrea Rossi could seal a unit, and send it to independent testing along with instructions for how to test it. It would be reproducible, and he would still keep his trade secrets. But he has refused this.

    No, and you show your ignorance by saying so. They first did tests on the SAME, unfueled cylinder, which were necessary for calculating their results. THEN, they witnessed the fueling, and conducted their experiment. If they HADN'T measured the thermal characteristics of the unfueled unit first, they would have been dropping the ball.
