After lengthy calibrations and modifications, we finally launched test a high-temperature calorimeter at full capacity. While we had reached the temperature to 1200 C, at a power of 250 watts. Calorimetry accuracy with an error of 2-3%. For the future it is possible to increase the operating temperature up to 1350 C.

Welcome to the Alpha Research project thread!We are a group of enthusiasts with background in physics and mathematics keen on research in promising areas of science, such as new energy sources, new methods of creating drive force, new communication devices and so on. At the moment we study [lexicon]low energy nuclear reactions[/lexicon] (LENR) and perform experiments based on works of A. Rossi, F. Piantelli, A. Parkhomov and other pioneers of this field. We are open project and invite everyone to take part in discussion of our experimental results, to share ideas and to cooperate with us. Be a part of a better future!
Our additional resources:
Launched spent reactor test thermocouple, this time everything was clean.
Experiments by MFMP have suggested that there is a possibility of electrical leakage between the heater coil wrapped around the outside of the reactor tube and a thermocouple placed inside if the heater power supply is not isolated. Apparently it can arise as the conductivity of the alumina increases with temperature forming an electrical path. Possibly the anomalies in the thermocouple are due to electrical interference? Did you post details about the electrics of the experiment setup?
Just trying to understand the experiment setup. From the pictures, did you use a copper pipe coil for the calorimetry?
Without the raw data it is a little difficult to tell but the calorimetry output follows the input power fairly closely. I don't see any obvious signs of excess heat.
Copper tube used, previously were also similar experiments, but without calorimeter, there just was not abnormal heat and anomalies with thermocouple. Now there are a few guesses, one of them is a connection with hydrogen and air, condensation.
The calorimeter setup looks good.
Have you done a calibration run (without fuel) for this calorimeter ? How did the power and temperature curve look like for calibration ?
Is any raw data available ?
Calibrations were a few, this is one of them.
Experiment of 17 July
The total time of the experiment 18 hours
The fuel composition
Carbonyl nickel of 5 microns - about 1g
LAH - 0.1g
Important! Nickel capsule walls do not touch walls of the tube, thermocouple concerned only the capsule wall.
Precise data on the ceramic tube is not, but it is known that it is vacuum-tight.
Heater power AC frequency of 50 Hz, the adjustment occurred by increasing the amplitude of the input signal to the power amplifier.
Now the graphs, to the right watts power readings (input - orange bar, output - green) temperature scale left - yellow readings.
Deviation 8% calorimeter (power loss 7-8%), with maximum temperatures of minimum loss was 1.5%.
The main question today - why such anomalies thermocouple? The graphs clearly show that even at a temperature of 1200C to sharp differences arose. Maybe someone faced with a similar and will be able to explain? While come to mind thoughts of mundane problems thermocouple inside the tube.
Hi all, today is a lot of conflicting and possibly misleading information, the experiment was launched at 11:30 Moscow time, the duration of 12 hours.
Add the translation for the presentation.
I leave my mail, of course. But I'll soon be very busy and can not respond before June 15th. Just acknowledge that I still difficult to communicate in English, but I gradually teaching him.
I think to sum up the results of the last of an experiment.
Exothermic reaction was still, but very weak. After removing the burnt spiral with fuel cell was discovered discharge of thermocouples with a piece of cement by about 2 mm from the surface of the reactor. On the second empty reactor, coil and a thermocouple were whole, there were only small cracks on the surface of the cement, once again, the material, the length of the resistance spirals were completely identical.
Suppose that the difference in temperatures in the range above 1000 ° C reached ~30%, the reason for that was a defect of fastening a thermocouple on the reactor with fuel to cause rapid combustion and a spiral (1), while the other remained without evidence of deterioration (2).
But it's the thought, intuition.
The inside tube seems intact. You could refurbish it with a new wire. And retest it with a faster growth of the temperature.
Yes, I plan to do so with a thicker coil and operating temperatures up to 1300 C.
A little later will report, tube whole, burned only spiral and thermocouple.
Less than an hour I start the stream. Schedule heating reactor add later.
I would like to apologize for the delay in the launch. I had to go to the other end of the city for a second power meter. On the road, I thought how very clearly identify any excess heat. Now I will collect a second reactor, but without fuel, I connect it to the working reactor in series, and will monitor the temperature of the two cells at the same time.
I think for me and for you the best starting time will be tomorrow morning, undue haste could damage the experiment.
The first reactor cell from the ceramic tube is ready, the fuel used by Parkhomov nickel.
A little technical data:
Size (DxdhL): 10x5x140 mm
a rod of circular cross section
Size (DhL): 5,0x40 mm
Material: alumina ceramic grade S799
Max. operating temperature of the material: 1600 ° C
The fuel composition
500 mg of nickel
Cantal - 2m = 57 turns, 10.58 ohms, the diameter of 0.6mm.
To seal the used refractory cement prescription Parkhomov.
Al2O3 powder ~ 2 μm particle size - 1.5 g
ZnO powder particle size unknown - 0.5 g
Na2SiO3 solution 37.5% - 2.9 ml
The cell is assembled as in the photo, the two sleeves are recessed into the tube to 5mm, 50mm cavity tube filled with fuel.
Complete sealing of the spiral should slightly increase the service life of Cantal.
Thermocouple not installed before the experiment will be collected second cell without fuel, temperature measurements which are held inside and outside, and the findings make the necessary calibration for the working cell. Measurements of the temperature will produce a thermocouple attached to the surface of the reactor.
The launch is scheduled for today, but the date may be pushed to the next day. A few hours before I Stream, notified separately.
Running on new reactor materials will in the coming days, I'll let you know in advance of the launch.
Conclusions after the experiments with quartz - quartz does not fit or use the tube with very thick walls. The entire reactor tube can be seen a large number of microcracks. Inside there is fragile white coating that is likely the result of reaction of the fuel with quartz. The spiral of nichrome covered with solid white microspots, pleasant to the touch, is likely the result of the reaction with hydrogen.
It was the last experiment with quartz, now has 20 of ceramic tubes brands С799.
Less than an hour I run the experiment, as well as control manually, the thermostat will insure in the event of a sharp rise in temperature.
Every hour will update photos from sensor readings. The experiment was designed to test hydrogen leak through the quartz
