Ambitious. And while I do love "practical" (physical) models, this one details all the reasons I went in for computer modeling when I discovered it back in the '90s. Physical models take up so much space, need to be dusted, and haunt you with the various limitations of whatever you made them from. In this case, it almost breaks my heart to see the amount of effort being put into something so cool that is also so fragile—and not fragile like a Faberge egg. Fragile in the sense that a sunny window could fade colors, dry and warp the materials.
I'm not naysaying! Second star to the right, and straight on 'til morning. This is cool.
But even the portion of the model seen in the video above made me think. The ship is more than just walled off spaces. Some sci-fi writers have stepped out of their own time to wonder what future engineering might look like. How much space is needed for ducting, or is there some engineering ahead of our own time that obviates the need for such bulky construction? Simple lighting has changed immensely since the time the TV show was made.
I loved the look of the Moonbase Alpha interiors in Space: 1999. They were brilliant from a production standpoint as well as "in universe." There were maybe a dozen types of wall modules. Each week the producers could show you a new section of Alpha without building all new sets just by snapping the modules together. The space was new, yet "looked like Moonbase Alpha."
James P. Hogan put it into words when he described a space station in The Two Faces of Tomorrow. Extruded on-site, wall modules also included built-in plumbing for gases and fluids, wiring for power and data, and control microprocessors. "Snap together" a new space in jig time, and it is ready with only a little software configuration. That's the "in-universe" part, and it dovetails with what Alpha looked like.
Of course, stuff like that is hard to explore with a physical model, cardboard or otherwise. Even CAD engineers use "collision avoidance" software to avoid pipes or support structures that would be in each others' space... like Airwolf's landing gear, turbos and "chain guns" all in the same space!
