What is a spark-plug anyway?
Designing an apparatus means knowing as good as possible the essential components and their interaction. If You go to the junkyard and collect your arbitrary ignition electronics, ignition-coil, spark-plug, you are probably in for a surprise. Moderately modern components are evolving and are quite sophisticated. See eg here: http://en.wikipedia.org/wiki/Spark_plug -- Central electrode. And here: http://www.madehow.com/Volume-1/Spark-Plug.html Same with ignition coils and assotiated electronics. For LENR-related purposes it may suffice to say that typical spark-systems develop a bipolar damped voltage at the hot electrode in the range od 10...30msec, where motorbike-systems go up to 20 000 rpm, ie 300Hz, with spark energies of 0.0xJ to 0.3J per spark. The undesirable effect in the LENR-context is the bipolarity of the voltage/ionization direction, but is not killing the effect. It just has to be considered. As said, it diminishes the ionization efficiency by some 50%, which is an annoyance and mainly affects the stability of the mesh-grid-potential, which can be stabilized with a capacitor of sufficient withstand-voltage and capacity, ie several kV & several nF, as a first approximation. Note: I am trying to bring some hard parameters in here, and not Rossi said this, DGK done that, Chan exploded a tree, which does a disservice to the effect. Kill the concept, as I try to expose, and You do me a service. Spares me a lot of time. Thank You. Guenther
