You're talking apples and oranges.
Per is suggesting a *method*, not a material.

Apples and apples. Edison had an idea and tried to implement it. Per found
the "boolean" button in his 3d program, threw some inaccurate adjectives
at
it and talks it up like it's cross sliced bread.

Not at all.
Per has suggested sheet steel and plywood.
Many other materials can be implied including composites.
For what its worth, I saw a *new* material recently, 2 sheets that when the
sheets are pulled away from each other it automatically creates *webs*
(structural) in between the sheets (sort of like corrugated cardboard or
luan doors).
As I've said all along Per has simply suggested a *way* to do things, and
has implied the materials.
I'm suggesting that the method AND the materials are yet unknown.
Face it, to chastize Per is to spit in ones own face as he is speaking of
the future and none of know what that holds.
As for me I will continue to observe and be skepticle of all things, and I
will try to hold my tongue regarding things I am not an expert on.
