Nice presentation.
The negative results mean only two things:
1) Parkhomov never got excess heat.
2) He is holding some critical information.

Some people are saying that the international version is GRANTED. Is there any document or evidence showing this ?
-
Probably the experiment has already started. Is there any live data or periodic updates ? (E.g. on Google spreadsheet etc)
-

Soon i know more about AP..
@me356 , what is the name of replicators what would have succeeded ?Check this page which keeps track of all the replications : http://kb.e-catworld.com/index…-Cat_replication_attempts
You will need to see the references to know who has claimed success. There are many. Mostly in Russia and neighbors.If you know about AP's work, please let us know.

Parkhomov himself has disappeared, unfortunately.
-
So can we treat it as a control for Ni wire experiment ?
If yes, it eliminates the variable of H2 conductivity. -
Me, please set the temperature to 400C, so we can compare with the earlier experiments.
-
At 400`C, the power is lower by 2 or 3 W than before. This means that the excess is a bit more this time.
However I'm not completely convinced yet, we need a calibration again, or better, calorimetry. I recommend a calibration using a steel wire and LiAlH4.
Most probably, adding more Ni wires inside will increase the COP significantly. -
I see that the reactor is now alive with a temperature of 500`C at 90W.
Is it the same reactor or something has changed? -
@Ecco, thanks for the plots.
The last part of power plot is most interesting, where the power dips to 62.5 W with no apparent changes in the temperature. -
Thanks for trying it Me.
There should be a good arrangement to keep the power stable because if the power is constant and COP>1 then the temperature would go on rising. This will be a solid confirmation that COP>1 -
Is there a way to keep the power constant and observe if the temperature goes on rising?
-
@me356: that result outside the calibration range was in my opinion too optimistic due to too many assumptions needed to trust the trend extrapolation beyond calibration data, but 42W for maintaining a temperature 300°C as currently set (whereas it was 51.7W during calibration and 49.7W at the start of the run) cannot be easily explained except for potentially the previously mentioned drifts in heat distribution. Could you test how much power is actually needed now in the 50-400°C range, in 50°C steps in a steady state fashion?
Sorry I missed the cool down part. What was the power for 400C?
If it was 42W for 300C then the COP reached above 1.2 (compared to real calibration) -
It does not matter whether you choose Celsius or Kelvin as a unit, because only the temperature difference matters for the radiation law.
((450+273,15) K - (25+273,15) K ) = (450 K - 25 K)
Thus my calculation is completely correct.
But I agree that there are other uncertainties.
I guess you can not simply take a temperature difference, its actually T^4 - Troom^4. So the temperatures must be converted to kelvin.
See : http://hyperphysics.phy-astr.g…/hbase/thermo/stefan.htmlThe reason being that the black body is radiating a power proportional to T^4 and absorbing a power proportional to Troom^4, so net radiation will be proportional to T^4-Troom^4
Correct me if this is wrong... -
Me,
Can you tell us where is the temperature and power data in the text files you attached (which columns) ?
Thanks. -
Very clean calibration. I'm looking forward to your fueled run.
-
Someone mentioned that pure Iron (Fe) will not react with Li.
It needs to be confirmed. -
Congratulations to the group.
I think you should invite them here to post the details - setup, COP, fuel etc etc. -
Good to see your progress.
Perhaps temperature cycling is important. You need to keep increasing and lowering the temperature around the decomposition point of LiH.
We know that in the E-Cat a chopped AC waveform is used, but we do not know how its RMS value varies over a longer time period. Probably he cycles it up and down in a few minutes intervals.
If you see the older patent of Rossi, there is a clear mention of on-off cycles of input power (with a graph).
