I agree Sockmonkey, there's many developments that stalled for reasons unrelated to the technology, and are now considered technological dead ends. It looks like the Faucetmobile almost fell into this category. Imagine if Barnaby had been killed in the crash of the Faucetmobile, would anyone be building one now?
I think an interesting exploration is looking at the Faucetmobile as a low poly version of a deltaish flying wing. The question I have is what's the best minimum panels/mesh size. In general Barnaby has broken the surface up into 2 or 3 major sheets (each side). As I understand it, the reason they are talking about honeycomb panels in the next development is because the large sheet size makes buckling in the sheets inevitable, but if the sheets were half the size they are now (and 2x as many), and each panel were bent to have a tab for riveting to the next sheet, that tab could also have flange bent down, acting like a stiffening beam. I wonder at what stage you'd have a strong and stiff enough surface to fly.
Funny thing is, sketchup is actually ideal for creating faceted shapes like that.Since I discovered Coroplast, I have pondered if a fauxetmobile could be built from it. I'd want to 'tape' bent tab joins or worry about them peeling. It may work better to have one sheet bent to make the stiffener, the other crushed flat and lap jointed to it. A 103 fauxetmobile doesn't look very doable, however built, so it might be a later project.
Structurally, a fauxcetmobile could also be made of lots of short bits held together with a latticework of cables inside. All struts would be in pure compression with the cables handling all the tension. When the cables are loosened, and the fuselage allowed to collapse, a full sized plane could fit in a closet.
