Yes, normally 'thermal pulsing' from a PWM would be too "washed-out" to make itself felt inside the already hot reactor - since heat is effectively averaged out in a metal, and one does not get the full benefit of the speed of sound in the transfer medium. For instance a 50 Hz pulsation into a cartridge heater would be averaged out and would hardly be felt by the Ni-H filling... or at least, that is our normal expectation, based on experience. However, in thinking about this detail further, and re-analyzing the relative dimensions of the E-Cat, I am struck by the un-necessarily long length of the water intake manifold (which contains the axial cartridge heater). Why is it at least twice longer than it needs to be? Since Rossi has now admitted this is the primary heater, and not the "auxiliary" as it was intentionally mislabeled at first (or is he now being disingenuous?) ... it is all starting to make more sense than before, once you have access to one key detail. Plus, in analyzing the commercial cartridge heaters on Thomas.net and elsewhere on the web there are apparently none, in approximate L/D ratio which would get to full contact with the reactor having already gone down a long water manifold. Hmm ... none of it makes sense till you understand a possible phenomenon which can answer both quandaries. It would be a device know to every TEG expert but to very few outside the field of heat-pipes. Here is your Qu tip of the day .... :-) http://tfaws.nasa.gov/TFAWS06/Proceedings/Thermal%20Control%20Technology/Pap ers/TFAWS06-1010_Paper_Cummins.pdf "superconductivity" and super heat transfer only adds to the intrigue .... BTW, there is a back-story to the "supertubes" for those on this forum, and it concerns the fact that Gene Mallove had just received samples of Dr. Qu's tubes - which were meant to be tested at MIT - on the day he was murdered, but that story may have to wait on another posting ... And if you were thinking "Dr. No" instead of "Dr. Qu", don't forget ... Dr. Julius No was indeed a Wiseman...
