An effort to offset weight by using cutouts. Long practise in aviation, and each module will be sealed by applying fabric the way they used to at Zeppelin. Ideally the parts will form a folding triptych so that pontoons and braces fall into place prior deflation, while the craft can still be stored flat. Search on for fabrics for the underside, tho' plastic tarp or the material used on curtain-side trailers each an option. Note valve for the vacuum, eventually to be subbed by portable means or drawn by ducted fans used in propulsion; varying the speed of either allowing for adjustment of displacement on the move using stretch fabrics.
The ethos is fast-build... the IKEA generation throwing up tents at places like Glastonbury and leaving them there afterward. Bad as disposables seem, they consume less energy and material than traditional means of ownership.
