During the design of ISS there has been a few modules that have not been constructed or constructed and not used like the Interim Control Module which was constructed but not used or the US Propulsion Module; (there were many ideals about that but no hardware constructed),Transhab, X-38,Entrprise Module from Russia and the list goes on and on. I figure having these modules to make your own space station. Your thoughts Anyone?
