Is this an appropriate qustion for the engineering.stackexchange group?
Note that in the body of the question, I want to ask a simple question and I want to differentiate that question from the research that I did into trying to answer my own question. So I thought I will litterly be using the word 'Question' in bold and 'Background' in bold to differentiate the two. The backgorund area will have a discusion of components that various news sources (cited sources) claim are difficult to mass produce.
