I've sat on these thoughts hoping that my dissapointment would wane; after several days, it hasn't; so, here goes:
I really don't believe that trying to "think outside the box" is so-called "Rube Goldberg" thinking, in the negative sense in which it seems to have been used here. These kinds of thoughts have made actual leaps in science and technology many times over millennia.
Even if someone here should communicate something which may be initially considered by some others as being "stupid, ignorant, foolish", etc.; those ideas can be very valuable in that they may precipitate other ideas which have more practical merit. This kind of thing happens over and over again continuously. So, I, personally, reject the idea that "Rube Goldberg" is something that shouldn't be here. I encourage it!
Both Einstein and Tesla (and many others throughout recorded history) were "Rube Goldberg" thinkers, according to their "society" and peers, early in their careers; yet, they revolutionized our world.
Referring to other folks' ideas here as being "Rube Golberg" just puts them down and totally discourages potential progressive happenings on this website. I really hope this is not the direction being taken; as, I find this whole body of knowledge very enlightening; and, with good practicable thoughts, and practical information from many directions and areas of expertise.
To a few of you: Lighten-up on those with whom you don't agree; they actually have great value here too!
p. s. Many folks do not understand the difference between the words "practicable" and "practical": Practicable is used to describe an unproven idea which seems like it may work; practical describes an idea which has been proven to work; i.e., "Her idea may seem practicable; but, has not yet been proven to be practical."
