I was using Sm Co based magnetic powder. Curie point around 700C but it is only useable up to about 250C. (I expect some degradation of the material in hot H/D gas. Remember the old parking lot demo at ICCF-4 with the Samarium cobalt? I can't remember the couple's name at the moment. I am not sure about the thermal runaway. I have never been over 150C with it. (limits of my calorimeter and plastic parts). I would think that the Al bead bath would be a fairly good heat sink. Remember the transfer to the sink goes up with temp differentials. One of the "replicators" has made their own hot bead bath and will be trying at elevated temperatures. My first inclination was to submerge the whole thing into aerogel and a dewar. But, as Les Case found out, you have to have a thermal gradient or you have to circulate the gas through the powder .... or, as I am doing now, use some external stimulation for non-equilibrium hydrogen/deuterium. I am seeing a better results with a little D in with the H for Ni systems. D2

I was wondering how to compare this list of numbers with the observation at the conference. This result makes me curious as to whether or not the device reaches thermal run away at some drive temperature. Perhaps the components you have chosen tend to fall apart before the required drive temperature is achieved. This demonstration should make an impact upon those who witness it provided they believe that it runs for the extended time you mention. Is there any chance that you can construct one that hold together thermally until run away begins? I suspect that the magnetic source powder would fail before that temperature is reached. In that case, would a large external field perform the required task?

I’m pretty sure the water bath wasn’t at 397°C … neither 292°C From: DJ Cravens [mailto:[email protected]] Sent: vendredi 20 septembre 2013 23:14 To: [email protected] Subject: RE: [Vo]:Cravens report on NI Week demo E vs. temp was not done at the demo. However below are some typical (average) values from some old lab runs. I did not "calibrate" at the demo. I only showed that the sample was warmer than the control. That was the only point that was attempted there so there was no claim of amount of energy but it was around 4 watts. I did not want to confuse things and there was no time to calibrate. Just one sphere was hotter than its environment- that was it. The important point is that excess increases with temperature. You may want wait till the next issue of IE comes out to see some empirical models (Letts, in #112) for better data. Letts has fitted hundreds of data sets. temp C excess W 292 0.2 312 0.6 332 1.2 352 3.9 372 6.2 397 7.1 To: [email protected] Subject: Re: [Vo]:Cravens report on NI Week demo From: [email protected] Date: Fri, 20 Sep 2013 16:00:27 -0400 It is not clear how any form of energy gain is associated with this experiment. The demonstration appears to generate LENR energy, but the input function is not present. It would be educational to have a plot of energy generation versus temperature.

"Can you make me a chargerfor my Tesla car?" Charming. Indeed it is - and understated since the hot sphere transfers heat to thebed and to the control - so the actual gain is more than it appears. ... hey, Terry - are you the proud owner of a Tesla (or just wishing youwere)?
