			<description><![CDATA[ It is good that you can capture most of the heat and direct it to the moving air. My concern is that it might be difficult to establish the correct amount of air flow. Too much and the outside glass will cool down which will then reduce the temperature of the hydrogen. You might actually get valuable information by adjusting the outside glass temperature and determining how that effects the process. It seems that most times when new instrumentation is available, new discoveries are made.]]></description>

			<description><![CDATA[[quote name="David Roberson"]Have you decided upon an ideal T_GlassOut to use with the air flow calorimeter? I wanted to caution you that the air flow will most likely have a major effect upon the glass temperature as heat is extracted by convection. That temperature reduction will be reflected within the device. It has not been determined how important the hydrogen gas temperature is toward the LENR process. If you plan to keep the air flow very low so that all the temperatures remain nearly identical to the recent tests then your equipment downstream of the device must withstand that high temperature. I am thinking about the baffle material and the heat sensor wires, etc. One nice thing about a calorimeter is that it allows us to wrap the cell in heat reflectors or insulation and still measure the heat accurately.]]></description>

			<description><![CDATA[@Ecco, Oh wow, thanks for the graphs! The one in that PDF wasn't as clear, but those definitely clarify the behavior as power and temperature go up. Interesting to see it's response is much more sensitive to temperature than it is to power. At any rate, this suggests that even this small piece of a two layer wire still has plenty of headroom in these conditions. I really wonder where the max output point is.]]></description>

I was about to write a comment (which I quickly redacted since I wasn't very confident I was correct) on how excess heat appears to increase with heat, according to data in the pdf you linked, when this new chart, supposedly clarifying this, got posted there: http://i.imgur.com/A0OBf.png http://i.imgur.com/A0OBf.png The other one from the same discussion, based on temperature data that can be seen on the left portion of slide 2: http://i.imgur.com/pDJoY.png http://i.imgur.com/pDJoY.png]]></description>

			<description><![CDATA[Also interesting to notice from that link (unfortunately I don't know how to edit my own posts) and the data, is that the output excess seems to taper off as the input power increases, and is not strictly linear. This may imply there is a maximal rate the wire can work at (which is realistic), and any input after that point suffers from diminishing returns. However, it could be bimodal or more, too, where after a certain threshold it kicks back up again. So many questions, so much to explore. It's very exciting. What all this implies for our test cells here I'm not sure yet (at what point do these full wires hit diminishing returns vs input power/temperatu re?) -- we'll have to discover that ourselves I think.]]></description>

			<description><![CDATA[I have been putting together a model of the system and believe that the latest one does a reasonable job of simulating the operation. I can input the Power drive to the device and obtain the curves of T_GlassOut and PowerOut versus time. The non linear relationship between the two variables causes the rising edges of these waveforms to have different time constants than the falling edges. At first this seemed strange, but now my model reproduces the result. The time constants are dependent upon the pressure to a degree, but can be determined quickly from the data you publish. You are doing an excellent job of measuring the performance of the device which is demonstrated by my model.]]></description>

			<description><![CDATA[I was thinking: maybe there's something that can be done to speed up calibration runs, which currently take an enormous amount of time. What about applying for a short amount of time a higher power than needed in order to quickly heat the reactor to temperatures close of those of interest for each power step? Some time invested in finding a general purpose formula taking into account reactor temperature, input power delta and gas composition might save a lot of time later on. This could be then implemented in the automatic calibration script.]]></description>

			<description><![CDATA[I agree with Sanjeev. I think it would probably be a good idea to do the Hydrogen/Argon at 3.5 Bar again, since it's so far away from the otherwise tight pack of run results. This result should be kept as a reference, of course, but worth a double check I feel.]]></description>

			<description><![CDATA[The goal of this experiment is the duplication of another set of measurements from another lab It is a noble effort. The measurement tools are encumbered by the decisions of the past. I think the ideal measurement tool for this type of experiment is a "differential scanning calorimeter' DSC. For an introduction see http://en.wikipedia.org/wiki/Differential_scanning_calorimetry. jdk]]></description>

			<description><![CDATA[Another thing, I noticed that the Calib-75H2-25Ar -P3.5 is always off by a large margin, may be some sensors misbehaved in those runs ? Or may be it was the first, so some seasoning occurred. I highly recommend to do it again to remove all doubts. At what pressure do you plan to run the active wire ?]]></description>

			<description><![CDATA[Happy to see clean and predictable lines for all cases. 8) The resistance is a bit strange, but it varies only by 0.5 ohm max, so I wouldn't worry about it. That is R/Ro of 0.98, which can be ignored. Active wire may show R/Ro of 0.7 to 0.8. Anyway its a secondary thing. Is it possible to draw a plot of P_in vs convection and conduction energy also in addition to radiated energy ? It will help to total up the output energies and to estimate which component dominates. It will later help to estimate the error margins on excess power.]]></description>

			<description><![CDATA[@Nicolas Chauvin and 123star: I have written, that DC is used and there was a reason I explicitly stated that the frequency is zero and just the resistance is left. I know how it works ;-) With a good power supply the ripple voltage should be very low so on can neglect the AC components. It's not a source of a significant error. The procedure of determining the output power from the glass temperature has the potential to have way larger uncertainties and even significant systematic errors, imo. :sigh: But that is being worked on as I understand.]]></description>

			<description><![CDATA[Microcracks in the wire are pressed together by outside pressure and also if hydrogen penetrates the outer layer and makes it swell. The latter might however also create new cracks if swelling deformation is large enough. Maybe these effects could partly explain why gas composition and pressure affects the resistivity, because pressing cracks together should decrease resistivity.]]></description>

			<description><![CDATA[@Ged: I guess you are reading the graph wrong. What was done for the calibration is to vary the heating power. With higher heating power, the glass temperature of course rises, but so does the pressure (if there is no leak). You can't compare that with the observation, that the glass temperature appears to rise with lower pressures at the same heating power.]]></description>

			<link>http://www.quantumheat.org#comment-1036</link>
			<description><![CDATA[Ged, I agree it's very important to note that the inactive constantan wire doesn't make external glass temperatures rise inversely proportional with pressure. However, I think others noted that its emissivity spectrum might be different than that of the active wire, and this might affect temperature readings at the various thermocouples. This possible artifact is worth to be checked in detail. EDIT: following more recent comments by others, I think might have misread the chart.]]></description>

			<description><![CDATA[Interesting. Also good to see that as pressure drops, so too does T_GlassOut temperature, no matter the gas, in this new cell without an active Celani wire. Take note of this, it's very important. This could also imply that this new, "proper" glass is IR stable while the quartz was not. Or it could have implications for the activity of the "fried" Celani wire. As for the resistivity, very fascinating. Also very good at the resistances all converge (within the same glass) regardless of pressure once the temperature gets near the 270 C we want to shoot for. That cleans up the data for that temperature range, thankfully! Not sure why it's so different before hand. It seems that the microstructure of the wire is getting settled in after the first run; kinda like how pinging hot steel settles the lattice before it cools, and it stays that way permanently after. I guess this would be a "break in" period for the wire.]]></description>
