Reproducing the anomalous effects witnessed by a long string of researchers over the past hundred or more years including Thomas Henry Moray, Edwin Gray, Joseph Papp, Alexander Chernetsky, Andrea Rossi, Paulo Correa, Nikola Tesla, and several others is SIMPLE - at least relatively so. Monty Childs stated that the concept behind the SAFIRE device is simple and the same is true for other devices. It's simply a combination of achieving the negative resistance regime, producing the complex space charge configuration (macro-EVO) supported by double layers that produce ion acoustic oscillations, and adding the correct fuel additives or "catalysts." The result will be excess energy in many forms (heat, light, electrical surges, longitudinal waves) and transmutations.
I really wish there were a couple OPEN SOURCE groups building such devices and testing them. The good news is that a small scale device that could fit in a shoe box should work. There's no need for a giant chamber like the one The SAFIRE Project is using. Probably, the cost would be fairly reasonable and the hardest thing to find would be an individual that could invest the time to perform a series of tests.
The EVO phenomena is proving to be at the root of LENR and all these exotic technologies.
