Robert, I agree to the extent that the emphasis should be on what is "significant".
Yes natural gas has been used according to AR - so only the heat is absolutely necessary -- but an additional EM resonance, even if it is from eddy currents, could be helpful to maintain control. It is not either/or. Here is kind of the reverse situation where eddy currents are actually used in leak detection of SS. http://www.olympus-ims.com/en/ms-5800-tube-inspection/ . And also - in the images I saw - the resistor wires are spiral wound around each other so there could be more magnetic field than expected. Maybe Dave will run a sim on this in spice. Jones From: Robert Lynn To repeat myself, there will be no significant em field penetrating the reactor. So don't try to fool yourself that there is some special secret about using em fields to instigate or promote the reaction, also Rossi has claimed in past to have it running using gas heating. Rossi's setup only allows for heat to get in. The skin depth of the 3mm thick SS vessel will exclude all fields above probably about 100-200Hz entirely, and will greatly attenuate lower frequencies as well (DC would get through) but the surrounding magnetic fields in the resistors themselves are very weak anyway. (not that many turns). If he wanted or needed magnetic fields to penetrate the reactor then he would not be using spiral wound resistors arrayed around the reactor vessel, he would have a coil wound around the reactor vessel. As such preventing measurement of current and voltage through the heating resistors looks very suspicious - as there is nothing there to be sensibly hidden if we take him at his word.

Would you agree? SS spec sheet: http://www.northamericanstainless.com/wp-content/uploads/2010/10/Grade-310S- 314.pdf From: MarkI-ZeroPoint "It is possible that RF would pass through these ceramics, no?" Yes, more than likely that RF could pass thru a ceramic, however, if electrically conductive, then probably not. An E or B field will most likely go thru the ceramics, but the reactor vessel is stainless steel: "The most important element of the E-Cat HT was lodged inside the structure. It consisted of an AISI 310 steel cylinder, 3 mm thick and 33 mm in diameter, housing the powder charges. Two AISI 316 steel cone-shaped caps were hot-hammered in the cylinder, sealing it hermetically. Cap adherence was obtained by exploiting the higher thermal expansion coefficient of AISI 316 with respect to AISI 310 steel." End caps are made of 316 due to greater coef of thermal expansion: 310: 15.5x10-6 316: 16.5x10-6 For our noninvasive glucose sensor, we used a Ni-plated soft iron housing which acts as both a faraday cage to shield outside EM, and to complete a magnetic flux circuit which channels the flux from internal permanent mags. Since stainless is only about 50% Fe, a mag fld should penetrate it, but due to its electrical conductivity, an E-fld would not. In that case, is he using magnetic properties to help control the reaction? Is it causing alignment of grains, or forcing dipole oscillations to be aligned? -Mark From: Jones Beene Robert Lynn wrote: And all of the resistive heating elements are positioned around it, so they do nothing but deliver heat to the reactor contents - no special magnetic or electrical excitation can pass through the reactor vessel. There is still confusion on that point. From Forbes article: http://www.forbes.com/sites/markgibbs/2013/05/20/finally-independent-testing -of-rossis-e-cat-cold-fusion-device-maybe-the-world-will-change-after-all/ They described the E-Cat HT as a cylinder having a silicon nitride ceramic outer shell, 33 cm in length, and 10 cm in diameter. A second cylinder made of a different ceramic material (corundum) was located within the shell... It is possible that RF would pass through these ceramics, no?
