PhysicsProf Steven E. Jones circuit shows 8x overunity ?

Very interesting @nul.so despite the current being pulsed in a classic heat-cool magneto-thermodynamic cycle this shows net heat influx from ambient at the core

hello Steven and NerzhDishual

apologies for the long gaps in posting - i am continuing to investigate and log behaviour of related ccts

current tests are looking at 2 pulse ccts, with energy being returned both to their own sources (battery) and to each others - efficiency is high but currently still less than unity

i thought that you guys might be interested in the attached data

prompted by reading a 'paper' recently, describing the possibility of 'inverted population' action when magnetizing the core of a coil, and which suggested that there will be some evidence of energy flow into the core due to negentropic action, i started measuring the temperature inside the inner gap of the toroid compared with the temperature a little distance away from the toroid

the data is showing a definite drop in average temperature within the toroid (measured with two different probes and monitor devices)

the attached data is rather weird in that the temperature readings appear to be 'frequency modulated'!

it is unlikely that the cyclic nature of the temperature data is EMF pickup from the pulse circuit, since the pulse rate is approx 1 Hz and the temperature cycles recorded are many times slower than that (and indeed vary quite significantly themselves, depending on probe location)

data for 'ambient' temperature, as recorded inside one of the monitor cases, is by contrast very flat, increasing slowly from approx 21.25 to 21.5 degC throughout the period of data shown


i've normalised the graph data against the ambient temperature readings, referenced to a representative 21 degC baseline

the graph data represents temperature readings in degC against elapsed time in seconds - the probe was located initially inside the toroid for approx 5 mins, then it was relocated approx 10cms away from the toroid for approx 5 mins, then finally the probe was replaced back inside the toroid

it can be seen that the average temperature is lower within the central gap of the toroid than further away, and also that there is a cyclic nature to the temperature readings which changes significantly in frequency depending on probe location


interesting?

all the best

If you publish your test set-up and raw measurement data then others can replicate your experiments and discuss the possibilities.

@ profitis:  yes, the data does appear to support some endothermic behaviour

..sadly that hasn't been my general experience on this site - hence the addressing of my post to specific members who have a shared experience of these tests

 try this with different core para-materials to check for greatest temperature disparity @nul.try air core too.try ainslie's nichrome-air core at a current that doesn't heat the coil too much, wow.

Magnetic cooling is an old technology and is how liquid helium samples are cooled to temperatures just above absolute zero, using a process exactly analogous to the "room temperature refrigerator" cycle using gadolinium detailed above.

@nul-points:
The recent data set showing the cyclic temperature variations is interesting. But the total span of the data + noise appears to be about four tenths of a Centigrade degree, and there is at least one direct fluctuation in the data of three or four tenths of a degree. This data is too noisy to be interpretable, really. You are operating in a realm where statistical techniques applied to data from multiple, identical, trials is going to be needed to tease out any effect signature unambiguously. The last time I saw fluctuations like that in temperature data they were eventually  tracked down to two causes: the building's AC cycling on and off, and cleaning staff opening and closing the door into the laboratory.

But at least you are doing better than Bill Alek: His claimed temperature anomaly was perhaps half as large as yours, measured with a non-contact IR thermometer under poorly controlled conditions. That's good enough for him to proclaim "proof of cooling". That's fine, he doesn't really need to convince ME with better data because I don't matter. But maybe the people who DO matter, will eventually read and understand that extraordinary claims require a bit more rigor in the evidence put forth in support.
