I was exploring a possible mechanism for the Papp engine. If there is an endothermic reaction to 8Be requiring a moderate input and an occasional transition to 12C with a large yield whose probability is increased by the resonance described in the paragraph, that might be one lead to be followed. I was also wondering whether the Rydberg state brought about by the plasma confinement (assuming there is plasma and Rydberg matter) might factor into the enhanced cross section for the 8Be + 4He -> 12C reaction. > Furthermore, where does the 4He come from in LENR?

I was assuming that the owner of the Papp engine would go to the store and buy some He rather than try to make it by hand. :) Eric
