Testing the TK Tar Baby

@.99
Thanks for looking; I didn't think I had said anything like what he claimed wrt PWM power computation. He's probably gotten confused by some of the many absurd things RA herself has said about power computations, averaging, DC vs PWM vs AC, and so on.

Nice armour, by the way!

I hope it's holding up to the corrosive environment you have to deal with.

Is there any  news about when RA will be showing us how she makes that Paper 2, Figure 2 scopeshot?  These replications of her own work do not require special noninductive shunts or bypass caps on the batteries, they must be done with the exact apparatus used to make them the first time, of course! And so there should be no reason for delay in presenting these replications, that were promised to us many times, beginning months ago, even with specific days and times (By dinnertime, God willing) ....
These replications must of course be performed with intact mosfets wired as she has been claiming -- that is, according to the schematic in Paper 1-- , a full 6 battery stack at 73 volts or more, and a period of about 160 seconds, with 15-second gate HI duty cycle, with a positive 10-12 volts at the gate of Q1 but no current shown at all in the CVR during those gate HI times -- the key points to be addressed in her replication.

I'm also wondering how she intends to show that the mosfets are functioning properly before and after reproducing that scopeshot.

I hope it's obvious to everyone that this was just intended as a little humor... the only rifling I did was through the old thread to find .99's posted pic, and through google to find a suitable pic to paste it into. I mean no offense to Poynt99 by this and hope none is taken. I chose the armor because he is nothing less than knightly when it comes to the way he carries himself in these forums. If there was any confusion here, or if I offended you Poynt, I apologize.

sorry poynt, i'm sure you wanted to keep that hidden...

175ml of water was heated 14.4C in 3 hours taking .9766867Watts to do that, but the heating circuit used only .43885Watts to do it.

Astounding. Gmeast can achieve precision to the tenth of a microWatt. Why, that is ten thousand times better than MOAC, which can measure to the milliWatt in good conditions-- and it is considered to be one of the world's most precise bulk calorimeters in civilian labs.

Either that.... or his numbers are wrong. After all, in the other part he is saying .43885 Watts is the actual value. A hundredth of a milliWatt precision, only 100 times better than MOAC can achieve after a week of stabilization and calibration.  Not .43884, or .43886, or even what I might say, "About 0.4 Watts". So if the actual value is NOT found to be 0.43885 Watts exactly.... his numbers are wrong.

Someone should remind this scientific researcher gmeast, experienced as he is, that the result of his computations cannot possibly be more precise than the LEAST PRECISE of his measurements. Sig digs and all that there neat stuff.

A tenth of a microWatt precision in the answer ... when the temperature rise is specified to the tenth of a degree C and the water quantity to the nearest milliLiter... if that.
I laugh in my coffee... all eight ounces of it.
