A further thought. Consider the fuel intake valve of an automobile. We all know that these can not be perfect and thus allow absolute isolation between the extremely hot gases within the cylinder and the intake mixture. Some explosive gas and heat must get to the intake mix but it does not ignite. I suspect that the heat injected within each small volume of input mixture does not reach that required to trigger a reaction. If the leak becomes too large then backfires would most likely result.
I think of the LENR reaction as being similar. The melted cavities that are seen on active experiments appear to me to be a cascade of individual small reactions. There is enough energy released within an active volume to spread outside of that region into the next sensitive one. This process would continue until the heat generated per volume no longer supports the heat loss through its surface area at which time the reaction quenches. There may be methods of controlling the energy generation volumes such as with magnetic fields which may be DGT's technique. The energy transfer through the surface areas of the tiny volumes of active LENR regions may be in some other form than heat such as radiation but the cascade would be similar. I can imagine that a focused beam might even occur where the reactions proceed along a relatively narrow path similar to a laser amplification. If this were the case then a cone shaped expulsion of melted material could appear which looks suspiciously like the pictures I have seen.

I'm looking for an answer involving a molecular level analysis.) >Sunlight will cause ignition, with only slight focusing. Magnifying glass is sufficient. Be my guest to try it, but stand back... This indicates that it is not only energy per photon that is important, but energetic photon-density per unit area. -----Original Message----- From: mix...@bigpond.com Hi, Here's a little conundrum that has troubled me for some time. Take a cup of gasoline and place it in open sunlight. It will slowly evaporate. Bring a flame near it and it will suddenly ignite. Why don't the UV rays from sunlight cause ignition?
