Nanoporosity became evident on the sharp edges of the steel wool, which is why I used it instead of a flat piece of iron. There was no target cavity size. The idea of the steel wool was a scattershot random construction and if the right pit size happened to be included, then the shadowing of the fibers behind those toward the hot evaporating filament might include even more and thinner porosity. In any case, I had results. Your proposal involves concepts more sophisticated than mine. But I think we have the same general idea.
