Rosemary Ainslie Quantum Magazine Circuit COP > 17 Claims

[MarkE]

Sometimes there are people who need reminders of the reminders:

"The experiments conducted:  June 29, August 10, and August 11 failed to reproduce the results reported here."

"The privately conducted August 10, and publicly conducted August 11 experiments were unable to corroborate net zero or negative battery draw during periods of Q2 oscillation."

"We therefore obtained heat output that was only a fraction of the input power."

"As we are unable to replicate our earlier reported results, we respectfully withdraw this paper in both of its parts."

[TinselKoala]

Ah yes... but recall that at the end of the August 11 demonstration, Ainslie can be heard protesting to Steve Weir that they got completely different results, at the exact same settings, before Steve showed up. And of course we believe the Great Scientist... don't we?

Meanwhile, I've been doing some DC calibration runs with the Tar Baby load, using the Arduino intervalometer photo data logging, and then transcribing manually to the spreadsheet for graphing.

Here's an example data set at one DC power level:

This is a 60-minute run, sampled once per minute, played back at 1 sample per second.

And here's the graph, attached below, generated by several runs at different DC power levels. Notice anything interesting?

I notice a couple of things:
There are at least two time constants in the system, a pretty short one and a long one. 

I also notice that the temperature rise versus power coefficient decreases with power, as expected due to increasingly efficient leakage from the vessel with higher temperature drop.  Going from 3.5W to 20W the leakage reduces the temperature rise / W from 3.1C/W to 1.9C/W.  That's probably due to increased convection.  A donut shaped piece of cardboard over the radiant barrier wraps might help that a bit. 

If the 9.76W run had heated up by 23C the linearity would be pretty damned good above 5W.

And I notice the 9.76W run never quite stabilized, suggesting something wasn't completely sealed up.

    I would almost think you guys would be totally tired of beating a
dead horse. Yet, you continue to kick it and seem to be enjoying your
selves while at it.
   I stopped reading this thread long ago and still it continues. Would
this not class as a total wast of time?

TinselKoala is still conducting useful and informative experiments.  I don't think there is even the corpse of a horse left to beat.
