			<description><![CDATA[In modern society, the lab glass reactor has important effects on many ways. Here: www.toption-china.com/products/lab-glass-reactor. Actually, this equipment is sometimes called ultrasonic cell grinder under many situations. At present, a lot of ultrasonic equipment suppliers begin to supply amount of related products. In fact, most people may not very unfamiliar with this product.]]></description>

			<description><![CDATA[Current temperature readings are biased because I had to put an aluminum foil on the top of the cell to increase artificially the temperature inside the cell with 10 more degrees that what I was able to do with my current power supply. I had 165°C with 56V (max) and 0.9A. So I did try to find the sweet spot to reach maximum loading temperature.]]></description>

			<description><![CDATA[@ Al Potenza In this calorimeter design, we eliminate the need to know the exact mass of air flow or the exact specific heat by measuring the number of watts it takes to heat the air 1 degree. Then we measure the temperature rise in the air after flowing through the chamber. Then it is simple math. In a perfect world the math is linear. In the real world it will have a curve due to any number of losses and imperfections. They are compensated by calibrating the unit with a test heater stepped through many different wattages. The resulting calibration curve compensates for most errors. The unit is insulated, but for high resolutions it will still need to be in a pretty constant temperature environment.]]></description>

			<description><![CDATA[The increase of pressure to around 8 bar has caused the cell time constant to increase to approximately 423 seconds. This is substantially longer than the typical 344 that I have been measuring. It is also noticed that the T_GlassOut is slowly rising as the pressure is slowly dropping during this test. It would be interesting to correlate the time constant of the cell with the pressure. Perhaps the extra gas adds thermal mass to the system.]]></description>

			<link>http://www.quantumheat.org#comment-1102</link>
			<description><![CDATA[I am not sure of the best place to discuss the new air flow calorimeter. It looks very nice and you have obviously thought about the design a lot. I was wondering if you'd planned for some insulation on the exterior to shield it from air currents. Otherwise, you may have the same problems you had before of instability. And are you measuring the air flow? If so, you can have an independent "first principles" method of measuring the enthalpy from knowing the mass flow of air, the specific heat, and the temperature rise. This is the difficult way to go. A liquid or even a Seebeck "perimeter" or "envelope" style of calorimeter would have been way easier in my opinion.]]></description>

			<link>http://www.quantumheat.org#comment-1101</link>
			<description><![CDATA[@Ecco No, because the glass will have same IR transparency during calibration period also. It's the excess that matters, not the absolute value of radiated power. Celani's setup is not suitable for accurately measuring the energy the glass radiates, his setup only shows that it radiates more than expected, hence the anomaly. It's pointless to calculate power and all, if all variables are kept constant, the rising temperature will be proof enough. If its not possible to keep the variables absolutely constant, then the temperature rise must be shown to be much more than that due to variables alone.]]></description>

			<link>http://www.quantumheat.org#comment-1100</link>
			<description><![CDATA[@Ecco, From my use of the black/gray body equation, any time you assume emissivity is less than 1, you decrease the watts you calculate based on the heat you detect. The equation for a gray body (anything with emissivity less than 1) is P/A = es(Tglass^4 - Tambient^4) , where P is power in Watts, A is surface area, s is the Boltzmann constant and e is emissivity. If not all of the IR is being absorbed by the glass, then we'll have a lower Tglass, which'll lower the calculated power. There's no way losing IR detection could increase the calculation.]]></description>

			<description><![CDATA[@Sanjeev: with the curve fit method used by MFMP, that's what I thought too. After all, the US cell, which uses quartz glass (which is more transparent to IR than borosilicate), is showing less excess power than expected. However the criticism I read was about the irradiated power calculation with the Stefan-Boltzman n law, as used by Dr.Celani. That the borosilicate quartz tube isn't an ideal black body at those wavelengths is supposedly causing an overestimation of excess heat in his case. Do you think it's actually the case?]]></description>

			<description><![CDATA[Following a tip in a different forum, today I learned that Schott-Duran 3mm thick borosilicate glass as used by Celani might not exactly be completely opaque to IR wavelengths of interest (>2.5 micron / >2500 nm as mentioned by him in the email published above). http://i.imgur.com/EIZzK.png As Dr.Celani is assuming that at those wavelenghts the glass tube is behaving like an ideal black body, shouldn't this have some implications on the expected results?]]></description>

			<description><![CDATA[@MFMP: maybe off-topic in this blog post, but seeing the data from the EU cell, was a new wire (an active wire?) installed? I see it's currently running at about half the normal power, is this because you are already using hydrogen and you don't want to cause the impedance anomaly (and subsequent excess heat) occur just yet?]]></description>

			<description><![CDATA[The main time constant associated with the EU cell during the 12/8 6:00 region is very similar to those of the US cell. I calculate 344 seconds. It is also very evident that some outer glass cooling event happened at 6:12. My curve fit is nearly perfect except for a short period around that time. There appears to be a drop in temperature of nearly 2.5 degrees which is very unusual for these cells. Do you know of any strange happening during that time?]]></description>
