>Marten, One of the reasons for posting the "blue vortex" video yesterday was to show how a single wire can provide adequate RF as a stimulus.
The key feature of this is a spark gap which can be internal or external. Spark gaps are not very sensitive to heat. The blue light emission from the bulb is coherent enough to show that a single spark gap diode, combined with a coil (variation of Tesla coil) can provide RF which is capable of ionizing a noble gas. You do not need precision waves or lots of circuitry for this task - nor any kind of adjustment capability. What is needed only is a special kind of irradiation spectrum, which corresponds to a blackbody emission characteristic which you want to stimulate in that active material. In the case of Rossi, he likely need near UV not too different from the bulb. Thus the simplicity. Stimulation by RF to attain QM superradiance does not require high power. The light bulb shown was powered with a few watts. Get it? Jones Jones, for those of us who want to replicate Rossi, how does one go about building such a RF antenna? Any schematic or drawing. Any suggestions on frequency and power requirement as well as how to integrate it into the reactor design. You physicists tell us engineers how to build it and we will build it and try to replicate Rossi. Any suggestions and guidelines pointing us in the right direction will help a lot in coming up with a viable design. Jojo
