Are there any data on the pressures in either the Parkhomov or Rossi reactors that you know of? I do not know that a significant H pressure is required for the LENR reactions in these two tests. Bob- The is no actual pressure measurement that I’m aware of – for the obvious reason – no place for a sensor. However, since the calculations do indicate that there must be substantial internal pressure due to H2 release from the hydride, then we are presented with the deductive possibility that substantial pressure could be required for success. What caused me to think about it today was the reference to Naudin’s MAHG. This is a hydrogen filled device which could have been operationally similar to the dogbone, since it probably would have been an SPP device (incandescent cathode with a ceramic spacer). The SPP would not have been optimized however. Perhaps it did not work as well as it could, because it was operating at a partial vacuum (0.1 atm) instead of several hundred PSI. Here is the website, if you are not familiar with it. http://jlnlabs.online.fr/mahg/mahg1.htm
